In Am. Fern Journ. 60 (1970) 7—12 the late Mr. C. V. Morton published ‘A further note on the type of Platycerium alcicorne’ in which he contests the lecto-typification of Acrostichum alcicorne Sw. (nom. ill.) = Platycerium alcicorne Desv., as established previously by De Joncheere in Blumea 15 (1967) 443—445, i.e. on Plukenet, Amaltheum t. 429 = Herb. Sloane vol. 102 fol. 194 from Johanna Isl., Comores (BM). Instead, Morton advocated to lectotypify Acrostichum alcicorne Sw. by some sheets in the Afzelius Herbarium at Uppsala from Sierra Leone, representing the West African taxon now properly called Platycerium stemaria (Beauv.) Desv. |

Because of their size Platyceriums are in herbaria represented mostly by fragmentary specimens; often only nest-fronds or foliage fronds are represented in a mostly mutilated form. This, and the difficulty of placing Plukenet’s pre-Linnean protologue and plate, the independent description of Platycerium alcicorne by both Willemet and Swartz, and the various interpretations of three of Desvaux’s four species, have led to great confusion on identity and typification. P. alcicorne Desv. (new name, 1827) is accepted as the correct name for the Madagascar and East African species. It is lectotypified by Plukenet’s phrase-name Neuroplatyceros, etc. of which the type specimen after which the plate was drawn is in the Sloane Herbarium, London. P. stemaria (Beauv.)... |
