The form T. interrupta, Wall, is hardly worthy the rank of a variety ; it only differs 
from the type in having the lines of fruit more or less broken irregularly.—I do not 
doubt the locality of this plant, as Wallich has noted that his single specimen was for- 
warded him from Sylhet by his collector Da Silva, who collected there. 
40. DRYMOGLOSSUM, Presl. 
l. D. carnosum, Hook. Sp. Fil. v. 189. Rhizome wide-creeping, bearing scattered 
lanceolate-linear spreading blackish scales; soral lines when young not marginal, 
but in age often covering nearly the whole frond.—Hk. & Bauer, Gen. Fil. t. 784 ;

Fertile fronds sometimes linear, sometimeselliptic. The species is easily distinguished 
from the next by the scales of the rhizome: Hooker both figured and described the scales 
of D. carnosum from a rhizome of D. piloselloides, and Beddome's figure of the scales is 
rather suggestive of a compromise than characteristic. D. subcordatum, Fée (not an 
Indian form), has the rhizome densely clothed with spreading linear scales, and may be 
à variety of D. carnosum.
