    Description and taxonomic position of Maclura brasiliensis (Moraceae) (1973)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.389 (1973) nr.1 p.69
    Details
    Publication Date: 2015-05-08
    Description: During study of American Chlorophotas (Kaastra 1972) Chlorophora brasiliensis (Martius) Standley (= Maclura brasiliensis (Martius) Endlicher) and Chlorophora scandens Standley et Williams seemed not to be closely related to Chlorophora tinctoria (L.) Bentham et Hooker. The taxonomic position of Maclura brasiliensis was already called dubious by Bentham & Hooker (1880) and more recently also by Macbride (1937); the same holds true for Chlorophora scandens (Standley & Williams 1950). Chlorophora brasiliensis and Chl. scandens show much resemblance to some other genera treated by Corner (1962) as sections of Maclura: Maclura Nuttall s.s. (= Maclura pomifera (Rafinesque) Schneider), Cardiogyne Bureau, and Cudrania Trécul. Corner, however, did not mention Chlorophora brasiliensis nor Chl. scandens. There is at least one other taxon that seems to be closely related to the group concerned here, the genus Plecospermum Trecul. Bentham & Hooker (1880) combined Plecospermum with Cardiogyne; Corner (l.c.) regarded it as a distinct but problematic genus. Richter (1895), on account of anatomical studies, pointed out that Plecospermum, Cardiogyne, and Cudrania could be regarded as a single genus.

    Revison of Chlorophora (Moraceae) in America (1972)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.382 (1972) nr.1 p.657
    Details
    Publication Date: 2015-05-08
    Description: After several pre-Linnean mentions (see: Bureau 1873), the name Morus tinctoria for plants belonging to the present genus Chlorophora was first validly published by Linnaeus (1753). Later combinations were made under Broussonetia Ventenat by Kunth (1817), under Fusticus Rafinesque by Rafinesque (1838), and under Maclura Nuttall by D. Don ex Steudel (1841). Rafinesque (l.c.) based the genus Sukaminea on Morus tinctoria L., without mentioning any species. Gaudichaud (1830) established the genus Chlorophora, based on Morus tinctoria L. Sp. Pl. 1753. The valid combination Chlorophora tinctoria (L.) was made by Bentham, who added the African Morus excelsa Welwitsch to Chlorophora (Bentham et Hooker 1880). Recently Corner (1962) made the combination Maclura tinctoria again, when reducing the genera Cudrania Trécul, Cardiogyne Bureau, and Chlorophora Gaudichaud to sections of Maclura Nuttall. Beside C. tinctoria several other species were described, e.g. Maclura chlorocarpa Liebmann, Maclura affinis Miquel, Maclura mora Grisebach, Chlorophora mollis Fernald. Especially Bureau (l.c.) and Hassler (1919) distinguished several infraspecific taxa. Woodson, Schery et coll. (1960) distinguished only one American Chlorophora species, C. tinctoria. It seemed worth-while to investigate with ample material how many species and infraspecific taxa there are.

    Leaf sheaths and obturators in Rutaceae \xe2\x80\x93 Pilocarpinae (1977)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht vol. 451 no. 1, pp. 317-320
    Details
    Publication Date: 2024-01-12
    Description: From morphological and anatomical study it is clear that the dilated leaf bases of Metrodorea can be regarded as sheaths. They are not homologous with the spines of Raulinoa, as suggested by Cowan. The outgrowths on the ovules and immature seeds of Pilocarpinae have to be regarded as obturators.

    Myosotis palustris en M. laxa in Nederland (1973)
    In:  Gorteria: tijdschrift voor de floristiek, de plantenoecologie en het vegetatie-onderzoek van Nederland vol. 6 no. 9, pp. 141-150
    Details
    Publication Date: 2024-01-12
    Description: In members of Myosotis ser. Palustres Popov occurring in the Netherlands 3 distinct taxa can be distinguished on the basis of karyological, morphological and ecological studies: 1 M. palustris (L.) L. subsp. palustris, palustris, M. palustris subsp. nemorosa (Besser) C. C. Berg & Kaastra, stat. nov. et comb. nov., and M. laxa Lehmann subsp. cespitosa (C. F. Schultz) Hylander ex Nordhagen. Distribution maps and a key to these taxa are given. The chromosome numbers are: 2n = 22 and 44 (endoploid) for M. palustris subsp. nemorosa; 2n = 64 and 66 for M. palustris subsp. palustris; 2n = 88 for M. laxa subsp. cespitosa; 2n = 55 for a putative hybrid of M. palustris subsp. nemorosa and M. laxa subsp. cespitosa.
