Beschreibung: In 1938, Verdam published an account of the then-known Charophyta of the Netherlands in the English language (cf. this journal, vol. 3), and one year later (1939) another in our own language in \xe2\x80\x9cNederlandsch Kruidkundig Archief\xe2\x80\x9d. In both papers reference was made to only five Netherlands\xe2\x80\x99 publications on the same subject, the oldest of which is dating from 1846. In studying i.a. the history of the Malaysian Charophyta (Zaneveld, 1940) I found that much more was published on the Charophyta of our Low Countries. As will be seen below, it became evident that the first printed record of a Netherlands\xe2\x80\x99 Charophyte dates as far back as 1636. It seems worth while to publish these notes on the history of the identification of our Charophyta as, moreover, a number of additional facts have become known.\nThe data of the present review have been taken from the following sources (chronologically arranged): 1. herbals ; 2. catalogues of Botanic Gardens; 3. local floras; 4. general floras and taxonomic textbooks; 5. monographs.

Beschreibung: The Talaud Islands are forming part of the Malay Archipelago, being situated north of Celebes and the Moluccas, south of Mindanao and east of the Sangihe group, between 3\xc2\xb045\xe2\x80\x99 and 5\xc2\xb035\xe2\x80\x99 N. lat. and 126\xc2\xb032\xe2\x80\x99 and 127\xc2\xb010\xe2\x80\x99 E. long.\nThe main group consists of three larger islands, viz. Karakelong, Salebaboe and Kaboeroeang. The Nenoesa islands, a group formed by the small islands of Garete, Karaton, Merampi, Mengkopoe, Intata, Kakelotan and Maroh are situated northeast of the main group, including also Miangas (Palmas), an islet about 65 miles north of Karakelong, near Mindanao.

Beschreibung: Several years ago the Director of the Bernice P. Bishop Museum, Honolulu, was kind enough to lend me the Sapotaceous material from the Pacific region preserved in its Herbarium. It has been enumerated underneath together with additional material from other herbaria. These have been quoted by means of the following abbreviations, which are taken from Lanjouw\xe2\x80\x99s list, published in Chronica Botanica V, 1932, 142. A. = Arnold Arboretum of Harvard University, Jamaica Plain (Mass.), U.S.A. B. = Botanisches Museum, Berlin-Dahlem. Bish. = Bernice P. Bish. Museum, Honolulu, Hawaiian Isl. and some specimens from the private herbarium of Mr O. Degener. Bz. = Herbarium, Gov. Botanic Gardens, Buitenzorg, Java. Cal. = California Botanical Gardens, San Francisco. G. = Institut de Botanique syst\xc3\xa9matique de l\xe2\x80\x99Universit\xc3\xa9 de Gen\xc3\xa8ve. GB. = Botanical Garden, G\xc3\xb6teborg. GH. = Gray Herbarium of Harvard University, Cambridge (Mass.), U.S.A. K. = Royal Botanic Gardens, Kew. L. = Rijksherbarium, Leiden. NY. = New York Botanical Garden, New York. O. = Universitetets Botaniske Museum, Oslo. P. = Mus\xc3\xa9um National d\xe2\x80\x99Histoire Naturelle, Lab. de Phan\xc3\xa9rogamie, Paris. PRC. = Botanical Institute, Charles University, Praha.\nBesides, a number of the specimens quoted are probably represented in other, particularly American herbaria, of which no data were available. I wish to tender my sincere thanks to the directors of the institutions mentioned for their kind assistance.

Beschreibung: Contrary to what Pliny and Dodoens assert, Satureja hortensis appeared to be very deleterious to onions when these species were sown together.

Beschreibung: La tourbi\xc3\xa8re au Sud de Veenendaal, dans la Vall\xc3\xa9e Gueldroise, ayant environ la forme d\xe2\x80\x99une halt\xc3\xa8re, a son origine dans une nappe d\xe2\x80\x99eau eutrophe, d\xc3\xa9ja pr\xc3\xa9sente lors de la premi\xc3\xa8re phase du tardiglaciaire. Dans les commencements s\xe2\x80\x99y forma un s\xc3\xa9diment (sable humeux), qui se composait, outre de restes v\xc3\xa9g\xc3\xa9taux, de sable apport\xc3\xa9 par le vent. Il est impossible qu\xe2\x80\x99un bras du Rhin ait coul\xc3\xa9 l\xc3\xa0 en ces temps. La tourbe se compose de mati\xc3\xa8res successivement eutrophes et m\xc3\xa9sotrophes. Une grande partie du profil (depuis le d\xc3\xa9but de l\xe2\x80\x99Atlanticum), est compos\xc3\xa9e de tourbe de marais bois\xc3\xa9 (Broekveen). Dans les sondages les plus m\xc3\xa9ridionaux on trouve de l\xe2\x80\x99argile dans les couches sup\xc3\xa9rieures (provenant probablement d\xe2\x80\x99inondations venant du c\xc3\xb4t\xc3\xa9 du Rhin). A mesure qu\xe2\x80\x99on s\xe2\x80\x99approche du Sud, l\xe2\x80\x99argile occupe une place de plus en plus importante dans le profil. Il n\xe2\x80\x99est trace de mati\xc3\xa8res oligotrophes (tourbe de Sphagnum), ni m\xc3\xaame dans le sondage VK (Veenkampen), o\xc3\xb9 cependant la carte g\xc3\xa9ologique mentionne une couche d\xe2\x80\x99argile recouvrant la haute tourbi\xc3\xa8re. La tourbe oligotrophe a sans doute \xc3\xa9t\xc3\xa9 compl\xc3\xa8tement enlev\xc3\xa9e par une extraction commenc\xc3\xa9e d\xc3\xa8s le moyen-\xc3\xa2ge. Il apert que l\xe2\x80\x99histoire des for\xc3\xaats que l\xe2\x80\x99on peut constater dans la tourbe, depuis la premi\xc3\xa8re phase du tardiglaciaire jusqu\xe2\x80\x99\xc3\xa0 la fin de l\xe2\x80\x99Atlanticum (premi\xc3\xa8re apparition de Fagus), est conforme aux r\xc3\xa9sultats acquis pour des tourbi\xc3\xa8res environnantes de cette m\xc3\xaame \xc3\xa9poque, par d\xe2\x80\x99autres investigateurs. Seulement un maximum prononc\xc3\xa9 de Corylus manque dans notre tourbi\xc3\xa8re. Les couches sup\xc3\xa9rieures de la tourbi\xc3\xa8re ne pr\xc3\xa9sentent pas de spectres polliniques r\xc3\xa9cents, mais les spectres qu\xe2\x80\x99on y trouve ferment un ensemble harmonieux avec ceux des couches plus profondes. Nous avons constat\xc3\xa9 que la couche de mousse vivante, dans le Bennekommer Meent offre un spectre pollinique qui repr\xc3\xa9sente assez bien la v\xc3\xa9g\xc3\xa9tation foresti\xc3\xa8re actuelle. Nous avons d\xc3\xa9crit un sondage dans une petite tourbi\xc3\xa8re isol\xc3\xa9e a l\xe2\x80\x99Est du Emmikhuizerberg, qui offre enti\xc3\xa8rement un caract\xc3\xa8re tardiglaciaire. Au cas o\xc3\xb9 l\xe2\x80\x99examen de GL et de AH III et \xc3\xa9ventuellement d\xe2\x80\x99autres sondages (encore en projet), nous ouvriraient de nouveaux horizons, nous donnerons en temps et lieu des informations a ce sujet.\nNous avons accompli cette \xc3\xa9tude au Mus\xc3\xa9e et Herbier Botanique d\xe2\x80\x99Utrecht (Directeur M. le Professeur A. A. PULLE). Je tiens a remercier ici M. F. FLORSCH\xc3\x9cTZ pour ses pr\xc3\xa9cieux conseils et pour la mani\xc3\xa8re enthousiaste avec laquelle il a bien voulu guider ce travail. En m\xc3\xaame temps je veux exprimer ma gratitude affectueuse envers Mlle A. M. J. VAN BERESTEYN pour la traduction dont elle s\xe2\x80\x99est charg\xc3\xa9e.

Beschreibung: Though an excellent, critical monograph of the genus Cassipourea was published some years ago by ALSTON (in Kew Bulletin, 1925, p. 241\xe2\x80\x94276), I should like to make a few remarks on the South-American species of this genus as my revision for PULLE\xe2\x80\x99s Flora of Suriname III.2 has brought to light a few new facts. It will also give me an opportunity to refer to a publication of BRIQUET on some American representatives of this genus (in Candollea IV, 1931, p. 342\xe2\x80\x94350), which disagrees with regard to a number of species with ALSTON\xe2\x80\x99s interpretations.\nThe species which covers the largest area is the chiefly West-Indian C. elliptica (Sw.) Poir. Formerly also a number of West- Brazilian and Peruvian specimens were referred to it, but ALSTON pointed out that these plants belonged to another species for which he introduced the name C. peruviana. A new West-Indian species, based on Broadway nr. 3841 and 4631, both from Tobago, was described by BRIQUET under the name C. Broadwayi. This species is, in my opinion, conspecific with C. elliptica. BRIQUET amply discussed the differences with C. latifolia Alston from Trinidad, but does not mention its relationship to C. elliptica. , though, in view of the latter\xe2\x80\x99s area of distribution, this would have been more to the point. That ALSTON had already referred Broadway nr. 3841 to C. elliptica was apparently overlooked by BRIQUET. In opposition to BRIQUET I agree with ALSTON that no value should be set on the varieties of C. elliptica described by GRISEBACH (Fl. Br. W. Ind. Isl., I860, p. 274).

Beschreibung: Het Hurener Veld is gelegen in de provincie Overijssel, ten Noorden van de spoorlijn Almelo-Zwolle; tussen Wierden en Nijverdal (zie kaart, fig. 1). Het maakt deel uit van een klein veen van ongeveer 13,5 km\xc2\xb2, dat nu practisch geheel ontgonnen is. Dit veen ligt in een dal, dat in het Oosten en Westen begrensd wordt door heuvelruggen, die ontstaan zijn door stuwing van de Riss-gletschers.\nAan de Westkant zorgt de Regge voor de afwatering van dit dal. Deze afwatering moet echter zeer onvoldoende zijn geweest, waardoor in het dal veenvorming mogelijk was. Het ontstaan van het aangrenzende moerasveen (lagg) in het Noorden kan ook het gevolg zijn geweest van deze onvoldoende afwatering; ongelukkig genoeg is dit moerasveen geheel ontgonnen, zodat een onderzoek naar het verband met het veen van het Hurener Veld onmogelijk is.

Beschreibung: The genera Mina and Lepistemon belong to the Ipomoeeae Hall, f., Stictocardia and Argyreia to the Argyreieae Hall. f.

Beschreibung: In recent years Baehni has provided us with some elaborate studies on the Sapotaceae (1, 2) and we understand that it is his intention to continue the series of generic monographs.\nAs I pointed out in a criticism (8) concerning the first of his papers, this seemed not a very successful beginning, be it only because one usually does not start a series of generic monographs by giving a survey of the whole family with the nature of a conclusion, without risking the judgment of prematurity. As might have been expected this paper contains a number of incorrectnesses, which may largely be ascribed to an insufficient knowledge of this intricate and difficult family.
