Note. — Nos. 17 to 20 of this work are four Supplementary Numbers to " The Ferns of Southern India" and contain all the 
Ceylon ferns not as yet detected in Southern India. Since the first portion of this work has been in the Press, three of these ferns have been 
found on the hills near Courtallum in the Tintievelly district, and one has been detected on the Nilgiris, many more will doubtless still be 
found in Southern India, as most of them are also natives of Northern India, Burmah, or the Straits, so that this work would hardly be 
complete if they were not figured, all the other ferns found in Ceylon have already appeared in the former numbers of this work, so 
the entire work of 20 numbers will contain figures of all the ferns of Southern India and Ceylon.

1. Momgramma Junghuhnii. (Hooker.) Rhizome creeping hairy ; fronds linear filiform, grass-like, 2-3 inches long, 2 lines

Gymnopteeis. See page 15. 
1. G ymnopteris Feci. Var. pinnatifida. (R. H. B.) Fronds deeply and irregularly pinnatifid. Segments of the fertile fronds 
very narrow. 
Ceylon. (C. P. 1318.) 
A curious lyrate variety of the common Gymnopteris Feei. (See page 15.) I have not found it in Southern India, though the 
common form occasionally has the sterile fronds forked, variously lobed, or even sub-pinnatifid, the fertile fronds seem always to remain 
simple. I may here also mention that I have occasionally found the broad sterile fronds of the common variety with a contracted fertile 
apex (as in Hymenolepis), it is, however, an abnormal state.
