2. C. quinatum (Hook.) comb. nova. 
Gymnogramme quinata Hooker Sp. Fil. 5 (1864) 152, Tab. GGXVI1. 
No. 262, Ambasi. 
Reported, from the Solomon Islands to Sumatra. 
This differs from the preceding species in having a hispid, chestnut stipe, in 
being smaller throughout, with the leaflets thinner and abruptly contracted below 
the apex, and the margin subtended by a single row of areolae. 
The genus is between Syngramma and Coniogramme in its characters. In the 
form of the frond it differs from either. In essentials, it also differs from 
Goniogramme in venation and from Syngramma in the absence of filamentous 
paraphyses.

3. P. deltoidea spec. nova. 
Pteris P. creticae affinis, forma deltoidea; pinnis infimis tripartite, 
pinnula inf eriore pinnata pinnnlis 11 quattuor, pinnulis terminate et su- 
periore ad basin fissis; pinnis lateralibns ntroqne latere una fissa et 1 
(vel 2) simplice; pinnis vel pinnnlis ultimis omnibus linearibus 5-18 
cm longis, 8 mm latis, ubi sterilibus acute non grosse serratis; soris 
medialibus. 
No. 21,2, Ambasi. 
An obvious relative of P. cretica, but the relative development of the lowest 
pinnae too great to permit its reference to that polymorphous species. The stipes 
are stramineous below, light-brown above. 
4. P. ensiformis Burm. 
No. 21,3. 
Polynesia to India.
