Sikkim; alt. 3500-5000 feet, J. Scott. Assam, Mrs. Mack.—These are the only examples 
in the Kew Herbarium. I have several times collected the plant both in Sikkim, Bhotan, 
and Khasia; but it is far less common than Hemitelia Brunoniana. This species is a fine 
green, drying a rich brown, in texture so unlike the black-drying shining Malay A. late- 
brosa, that I strongly suspect it to be a different species. 
2. A. GLAUCA, J. Smith, in Hook. Journ. Bot. iii. 419. Frond glaucous beneath; 
veinlets (in the segments of a pinnule from the middle of a barren pinna) 2-branched,

surrounded by lax hairs.—M.ett. in Ann. Mus. Lugd. Bat. i. 54, with all syn.

Attains 50 feet (J. Scott). More or less prickly; fruiting segments more or less  - 
elongate; on the whole very uniform, and easily distinguishable from all other North- — S 
Indian Ferns. Neither of Beddome’s pictures is good; he shows an apparently well ` ` 
developed barren pinna without any 3-branched veinlets in the ultimate segments. - = 
J. Scott’s picture is excellent. 
3. A. ORNATA, J. Scott, in Trans. Linn. Soc. xxx. 36, t. 16 A. Pinnules glabrous be- ` 
neath, or the rhachis slightly flocculose villous; fruit-segments linear-oblong; —— 
crenulate-serrate ; veinlets (in the segments of a pinnule from the middle of a 
barren pinna) 2-branched, a few 3-branched; base of the carpophore, after the | 
“ie have fallen, naked.—Bedd. Ferns Brit. Ind. t. 342; Hk. & Baker, EL] D 
Sikkim ; alt. 2500 feet, Government Cinchona-plantation, J. Scott. 
Collected by J. Scott twice apparently. Two fertile pinnæ at Kew, communicated by 
J. Scott. Otherwise unknown tome. Attains 20—40feet, with a somewhat slender trunk. 
Seems to me more nearly allied to A. latebrosa than to A. Oldhami, but well distinct ; ` 
the veinlets are much wider apart, sometimes 3-branched. Here, as in other species, 
there are no pinnate veinlets (as might be inferred from J. Scott’s words) ; at the tips of 
the frond Wie videtur being imperfectly developed, become confluent ; BI the m
