NOTES ON NEW AND OLD GENERA OF PLANTS 383 
PILOPHORUM 
This name Pzilophorum is another example of one whose 
ending is indifferently used as om or um or even goes as Philophorus 
Nyl. Though there is an older Philophora Jacq.' Nevertheless the 
name of the fungus later used finds its way in all our books on 
these plants, and that too with the variations shown! This incon- 
sistency, moreover, does not seem to affect the matter in the least. 
We suggest the name Crinofera for the homonymous fungus name. 
POLYCEPHALUM 
Polycephalos Forsk? is an older name than the Polycephalum 
Kalchb. & Cooke. Gremlia may be used for the fungus homonym, 
in honor of August Gremli, author of a work on the flora of 
Switzerland. 
Gremlia Nov. Nom. 
Polycephalum Kalchbr. & Cooke, not Polycephalos Forsk. 
Gremlia aurantiaca (Kalchbr. & Cooke). 
Polycephalum aurantiacum Kalchbr. & Cooke. 
PTERYGIUM Nyl. 
Pterygium Nyl.can not remain as the Lichen name because 
of an older Pierygium Endl.3 also written Pterigium by Correa.‘ 
To replace it may be suggested Calkinsia in honor of W. W. 
Calkins a most zealous student and collector of American lichens. 
The plant had been called Wilmsia but there was another plant 
claiming that name. 
Calkinsia Nom. Nov. 
Pterygium Nyl. not Pterygium Endl. (1847) nor Pterigium 
Correa (1806) 1. ec. Wilmsta Korb. not Lahm = Pachyphiale Lonnr. 
Calkinsia subradiata (Ny].). 
Pterygium subradiatum Nyl. 
Calkinsia panariella (Ny]l). 
Pterygium panariellum (Ny). 
PYTHIUM 
Pythium Pringsheim would appear to be invalid because of 
* Frag. 32 t 35, (1800) Also Pilophoron. 
2 Forskal, Fl. Aegyp-Arab. 154 (1775).
