Description: This publication is a continuation of \xe2\x80\x9ePlantenkaartjes voor Nederland\xe2\x80\x9d, published by Dr. J. W. C. GOETHART and Dr. W. J. JONG MANS in the years 1902\xe2\x80\x941908. For both publications the same methods, differing in two respects from those usually adopted elsewhere, have been employed.\nAs in the first place it is utterly impossible to show on a very small-scale map, the exact spot where a certain species of plant is to be found, this mock-accuracy has been avoided. Only that part of the topographical map is indicated, which contains the finding-place. With this end in view, each of the 64 sheets of the survey-map of the Netherlands is covered by a net of 48 rectangles, each side being approximately one hour\xe2\x80\x99s walk long (exactly 4180 X 5000 metres). These rectangles are called \xe2\x80\x9ehour-squares\xe2\x80\x9d, each being subdivided into 16 \xe2\x80\x9equarter-hoursquares\xe2\x80\x9d of 1045 X 1250 metres. The \xe2\x80\x9ehour-square\xe2\x80\x9d, in which any special finding-place of a plant occurs, is clearly shown on a photo-lithographically reduced map with the \xe2\x80\x9ehour-square\xe2\x80\x9d division. As the scale of the reduced map is left large enough, even the \xe2\x80\x9equarter-hour-square\xe2\x80\x9d in question can be clearly distinguished within its \xe2\x80\x9ehour-square\xe2\x80\x9d.

Description: Culmi robusti, foliati. Folia lata, linearia, trinervia. Inflorescentia corymboso-paniculata, multispiculata. Spiculae (\xe2\x80\x9dspicae\xe2\x80\x9d multorum auctorum) parvae, multiflorae. Flores hermaphroditi (\xe2\x80\x9dspiculae androgynae\xe2\x80\x9d auctorum) perianthio utriculiformi, compresso, vix carinato, staminibus (\xe2\x80\x9dfloribus masculinis monandris\xe2\x80\x9d auctorum) tribus, binis lateralibus tertio anteriore, ovario (\xe2\x80\x9dflore foemineo terminali nudo\xe2\x80\x9d auctorum) rostrato, basi angustato, haud stipitato, styli ramis ternis. Nux tri-costata, rugulosa.\nGeneri Hypolytro L. C. Rich. proxima, a quo differt styli ramis tribus et nuce tri-costata. A Thoracostachyo et Paramapania, quibuscum stigmatum numero convenit, et structura florum et perianthio connato et nucis forma longe diversa, faciliter dignoscenda. Mapaniae potius affinis, sed ab omnibus speciebus huius generis inflorescentia a plerisque etiam perianthio connato discrepat.

Description: Genera Mapania, Hypolytrum, Thoracostachyum valde cognata sunt. Quamvis enim adhuc diversa sit botanicorum sententia de structura florum huius tribus morphologice interpretanda, de hac re omnes consentiunt, squamellas laterales binas generis Hypolytri, sive sepala sive glumas floriferas vocandas, squamellis exterioribus Mapaniae et Thoracostachyi homologas esse. F. Pax solum, qui cum nonnullis aliis auctoribus Thoracostachyum cum Mapania iungendo systema Benthamianum et Hookerianum secutus est, tertium genus, cui solo flores bisexuales ascribit, longe disiunxit. Conspectus generum usitatus ut in Hook. f., Fl. Brit. Ind. VI, p. 586, ubi C. B. Clarke Cyperaceas disposuit, ita fert: A. Spicula capitata .............................. Mapania B. Spicula corymboso-paniculata. 1. Stylus bifidus ...................... Hypolytrum. 2. Stylus trifidus ................. Thoracostachyum.\nHic conspectus autem numero specierum cognitarum sensim augente quibusdam vitiis laborare apparet. Corymbos a capitibus diiudicare non semper facile. Discrimen a numero styli ramorum sumptum incertum, quia in eodem genere sicut in Scirpo et in Carice, quin etiam in eadem specie, saepe mutari cernitur. Praeterea speciebus spicula singula praeditis nullum genus hospitium praebere videtur.

Description: The region, from which the Vernonieae and the Eupatorieae have been worked out, includes the Greater Sunda Islands, the Lesser Sunda Islands and the Moluccas. It is a well-known fact, that the Malay Peninsula and the Philippines have a flora, which is related to that of the Malay Archipelago, sensu stricto, belonging to the same region indeed. The Compositae of these parts have, however, been recently dealt with by RIDLEY (Fl. Mal. Pen. II, 1923, 177) and by MERRILL (Enum. Phil. Flow. Pl. III, 1923, 591) respectively, whereas those from New Guinea, which is floristically less related to the Malay Archipelago, have been worked out by MATTFELD (Engl. Bot. Jahrb. LXII, 1929, 386).\nThe material, used for this paper, chiefly belongs to the National Herbarium (Rijksherbarium), Leiden (L), the Herbarium of the Botanical Gardens, Buitenzorg (B) and the University Herbarium, Utrecht (U); for the rest it is to be found in the Herbarium of the Royal Botanic Gardens, Kew (K) and the Herbarium of the British Museum, London (Br. M.); some specimens of the Herbarium of the Linnean Society of London and of the Herbarium of the \xe2\x80\x9eConservatoire botanique de la ville de Gen\xc3\xa8ve\xe2\x80\x9d (G) have also been studied, whereas the type specimen of Vernonia arborea was discovered in the Herbarium of the Royal Botanic Garden, Edinburgh. I feel greatly indebted to the Directors of these herbaria for their kindness in putting these materials at my disposal.

Description: The Ericaceous genus Rigiolepis was founded by Sir JOSEPH D. HOOKER (Ic. plant, third ser. II (1876), 54, pl. 1160) on a single species from Borneo, viz. R. borneensis HOOK.F. HOOKER was not quite sure about some of the characteristics, and failed to compare it with Vaccinium to which genus, indeed, several authors have reduced it.\nIn 1914 I have discussed the Rigiolepis question (in Ic. Bog. IV, 68) in the note under Vaccinium uniflorum J. J. S. and was inclined to believe that Rigiolepis should be maintained as a distinct genus, although my material was not sufficient to solve the question definitely. Since I have studied many other species of this affinity and I do not hesitate to accept the genus.

Description: Das \xe2\x80\x9eKorenburgerveen\xe2\x80\x9d, in der N\xc3\xa4he von Winterswijk im Osten der Provinz Gelderland (Abb. I), etwa 110 ha, ist seit 1918 Naturdenkmal. Der gr\xc3\xb6sste Teil des Moores ist abgetorft. Nur einige Torfw\xc3\xa4lle sind erhalten geblieben. Die Oberfl\xc3\xa4che des Moores liegt um einige Meter tiefer als die Umgegend, welche haupts\xc3\xa4chlich aus Geschiebelehm und fluvio-glazialem Sande der Riss-Eiszeit besteht. In der Mitte des Moores wurde ein Bohrprofil von etwa 4 m M\xc3\xa4chtigkeit genommen. In etwa 200 m Entfernung wurde ein zweites Profil gebohrt. Beide Profile wurden pollenanalytisch und stratigraphisch untersucht, wobei es sich ergab, dass beide eine weitgehende Uebereinstimmung zeigten. Deshalb soll hier nur das erste und vollst\xc3\xa4ndigste Profil besprochen werden. Nur am Ende dieser Besprechung sollen einige im zweiten Profil hervortretende Unterschiede kurz erw\xc3\xa4hnt werden.\nAus dem abgebildeten ersten Profil (Abb. 2) geht hervor, dass wir es mit einem alten Moor zu tun haben, da in den unteren Proben die Erle praktisch nicht vorhanden ist. Die Birke ist am h\xc3\xa4ufigsten vertreten (56%), aber auch die Weide ist bedeutend (37%). In der untersten Probe zeigt die Kiefer nur einen geringen Prozentsatz (17%), steigt aber rasch empor bis 60%. Abwechselnd treten Kiefer und Birke am meisten hervor. In einer Tiefe von 3.40 m tritt eine wesentliche Aenderung im Diagramm auf, Kiefer und Birke verlieren ihre hohen Werte, w\xc3\xa4hrend die Erle scharf empor steigt, um bis auf einigen Dezimetern unter der Oberfl\xc3\xa4che der bedeutendste Baum zu bleiben. Gleichzeitig mit dem Erlenanstieg f\xc3\xa4llt das erste Auftreten der Eiche und der Linde. Letztere erreicht kurz nach ihrem ersten Auftreten ihren h\xc3\xb6chsten Wert (6%), um bald zu verschwinden. Bedenkt man aber, dass es sich hier um einen entomophilen Baum handelt, so ist auch ein Wert von 6%, der verh\xc3\xa4ltnism\xc3\xa4ssig geringen Pollenproduktion wegen, von einiger Bedeutung. Bald findet eine starke Zunahme von Hasel und Eiche statt. Beide Kurven sind anfangs mehr oder weniger parallel, w\xc3\xa4hrend von 175 cm an die Hasel immer weniger bedeutend wird. Die Eiche schwankt bis dicht unter der Oberfl\xc3\xa4che zwischen 35 und 15%. Die Buche ist zwar l\xc3\xa4ngst mit einigen Prozenten vertreten, erreicht aber erst von 130 cm an h\xc3\xb6here Werte, bis zu ihrem Maximalwert von 34%, in einer Tiefe von 40 cm. An dieser Stelle des Diagramms weist die Eiche einen um 10% niedrigeren Wert auf als die Buche. Letztere wird nun bald nach ihrem Maximum ganz unbedeutend. Die Hainbuche tritt erst von 75 cm an regelm\xc3\xa4ssig im Diagramm auf und erreicht einen Maximalwert von 6%.

Description: X.\nNOTES ON THE NEWLY DESCRIBED GENUS\n\nCACOPHRYNE DAVIS\nRecently Davis (1935) pointed out that the toad known in literature as Bufo borbonicus (Tschudi) or Nectophryne borbonica (Tschudi) does not belong to either of these genera, and that it even does not belong to the Bufonidae, for the species differs from the true toads (Bufonidae) in two important characteristics, as it lacks Bidder\'s organs and does not possess testes of an elongated shape. Moreover the pectoral girdle proved to be firmisternal instead of arciferal. A new genus, Cacophryne, in the family Atelopodidae, was erected for this species by Davis, and this author (1935, p. 90) mentions that possibly some other species at present included in the genus Bufo, i.e., Bufo penangensis (Stol.), Bufo cruentatus (Tschudi) and Bufo leptopus Gthr. might also belong to the genus Cacophryne. To ascertain whether this was really the case I examined some specimens of Bufo cruentatus (Tschudi) and two specimens of Bufo leptopus Gthr. Of Cacophryne borbonica (Tschudi) I examined some specimens for comparison.\nAs I had but two specimens of Bufo leptopus Gthr. I only examined the pectoral girdle of one, and this proved to be decidedly arciferal as in the true Bufo\'s. Of Bufo cruentatus (Tschudi) and Cacophryne borbonica (Tschudi) I examined especially the osteological characters, and these led me to conclude that both species are congeneric, and that, therefore, cruentatus must also be referred to the genus Cacophryne Davis.\nThe following notes may be given on the anatomy of Cacophryne borbonica and Cacophryne cruentata. The vertebral column consists of eight

Description: I have lately received for determination some very interesting sawflies collected in Java mostly by Dr. J. van der Vecht. The collection contained eight species not recorded in Forsius\' recent list of Javan Sawflies (Forsius 1934), six of these being entirely new species. The types of these new species have been deposited in the Rijksmuseum van Natuurlijke Historie, Leiden, Holland; paratypes and duplicate specimens where available have been retained in the British Museum. In addition to these I have added the description of a new species of Anapeptamena given to the British Museum by Dr. C. Ferri\xc3\xa9re. The additions to the Javan fauna are listed below.\n\nORUSSIDAE\nOphrynopus maculpennis (Smith) Bajoekidoel, Banjoewangi, East Java, 1 \xe2\x99\x82, IX. 1932, Toxopeus leg.\nForsius (1926) suggests that O. loriae (Mantero), and O. trifasciatus (Cameron) (New Guinea), as well as O. sericatus Mocsary (New South Wales) and O. queenslandicus (G. Turner) (Queensland) are synonymous with this species. The Australian species O. sericatus Mocsary, is, however, certainly a very distinct species from O. maculipennis (Smith) as I have indicated in the key below.\nThe Malaysian and Australian forms of Ophrynopus Konow can be distinguished from the Central and South American forms by the fact that segment 3 of the abdomen is about two-thirds as long as segment 2 while in the American forms segment 3 is about half as long as segment 2. In the American species also the ocellar region is usually about as broad as long, the tubercles being arranged in a semicircle behind the
