Lecanopteris deparioides or L. curtisii.


Recommended Posts

Lecanopteris deparioides Ces. (1876) John Gilbert Baker published this new combination in the Journal of Botany, British and Foreign 10, page 366, (1881), as an addition to his description in English of a supposedly new species he named L. Curtisii (sic.), but they are the same species.

http://www.biodiversitylibrary.org/page/34839810#page/381/mode/1up  p366.

Baker based his new combination of Lecanopteris deparioides on Dicksonia Deparioides (sic.) by Vincenzo de Cesati, supposedly published in Filices Borneenses 13, t4, fig8, (1876.)

However, according to Tropicos, http://www.tropicos.org/Name/50250532 Cesati actually published the basionym as Davallia Deparioides (sic.) in Atti della R. Accademia delle Scienze Fisiche e Matematiche di Napoli 7, 8, (1876) but original not yet available digitally.  Nevertheless, although not the original publication, this entry in the Journal of the Straits Branch of the Royal Asiatic Society; In a section entitled, The Ferns of Borneo, p37, (1878) thus written near to 1876, also notes that L. deparioides Baker was based on Davallia deparioides Ces., in Filices Borneenses: fougères receuillies par les expéditions de messieurs Nieuwenhius et Hallier dans la partie équatoriale de Bornéo, par H. Christ, 13, pl. 4, fig.8. (1876.) abbreviation = Fil. Born.  Again not yet available digitally, but see:

http://www.biodiversitylibrary.org/page/41737985#page/263/mode/1up p37.

L. curtisii (1881) and L. deparioides (1876) are identical species, which surely makes the former merely a synonym. Incidentally, Tropicos does not list L. curtisii at all.

Dr Honor Gay & Gay et al. (1990- 1994) in their various invaluable Lecanopteris papers, used the name L. curtisii Baker, which I think is incorrect.  Sources can be seen here: (the link now works.)

It was sunk into L. curtisii by E. Hennipman unpublished, hence now into into L. deparioides as currently accepted by https://worldplants.webarchiv.kit.edu/ferns/.  And others.

However, just to confuse matters, the name L. philippinensis has also been used for L. sinuosa and L. pumila collections.

Along with its New Guinean form (also considered by some to be a separate species) L. deparioides makes up the Gay et al. L. curtisii (sic.) group, now perhaps (???) the L. deparioides group, which are considered to be the most probable ancestral form giving rise to the L. pumila group (Gay 1993b, Gay et al. 1994.)

In this example, as far as I can ascertain, L. deparioides is the correct name, and L. Curtisii (sic) as used by Gay & Huxley et al. in their 1994 study, is an error.  I have no idea why such world leading botanists should regularly use a 'modern' specific epithet with a capital letter.  It certainly make me wonder if there is something here I don't know that I should know.

It seems no one reads my posts thoroughly. Although I found this error and have already corrected it in my book, no one noticed the glaring inconsistency in these copies. I have now corrected it by adding the prefix in (red type) to the word correct (see above). Dr Honor Gay & Gay et al. (1990- 1994) in their various invaluable Lecanopteris papers, used the name L. curtisii Baker, which I think is incorrect.  Sources can be seen here:
