I cannot agree with Baker in regarding this as a variety of E. petiolatum, It differs 
from that species in its much larger leaves, its glabrous surfaces, and the different scales 
of the rhizome. In Æ. petiolatum the scales are dark brown, glossy, very narrow, and 
nearly hair-like. In general habit our new species resembles not a little Æ. flaccidum.

Mahé and Silhouette, Gardiner!; apparently common. 
Most specimens are rather densely clothed all over both surfaces with minute pseudo- 
stellate scales. 
E. petiolatum type is common in tropical America; the variety is frequent in the 
South-east African islands, and Kuhn refers specimens from tropical West Africa to it. 
Very similar forms occur in Southern China and the Himalaya (4. neriifolium, Wall.).

As suggested in my ‘Index,’ it is uncertain whether this East-African Platycerium 1s 
the same as the true P. bifurcatum from Australia.
