HYMENOPHYLLUM. 
HyMENOPHYLLUM POLYANTHOS. (Sw.) At plate 267 of the Ferns of Southern India, I have figured under this 
name a fern from Ceylon which has been named by Van den Bosch, Hymenophyum macroglossum, but which is considered by Sir W. 
Hooker to be only a small variety of the true H. polyanthos ; as the Himalayan fern is so much longer and finer, I have given a figure of 
a specimen (from the Khasya hills), but will not offer any opinion as to whether the two are distinct species or only varieties—the 
Ceylon form I have lately found in the Anamallay and Tinnevelly mountains and elsewhere on the western ghats of our presidency. 
Sir William Hooker in his Synopsis Filicum includes under his H. polyanthos about 30 species of Van den Bosch and amongst others the — 
H. Blumeanum Spr. (Plate CCLXVI, Ferns of Southern India), which I have lately discovered on the Tinnevelly mountains (in the — 
` Ayen Coyl pass near Courtallum) and have no doubt about its being quite distinct from polyanthos. | | |
