Kashmir and Baltistan; alt. 5000-7500 feet, frequent. Kulu, ZEdgeworth.—Distrib. 
Cabul, West Asia, South Europe. 
Exceedingly like Ch. fragrans, and only to be distinguished by the indusial hairs. 
The hairs are really confined to the sori, which occupy a large portion of the very 
small segments, so that the lower surface of the frond appears densely matted. Ch. 
Szovitzii is the oldest name. Notholena persica is 4 years later than the full description 
of Oh. Szovitzii by Fisch. & Meyer. 
** Fronds not powdered beneath ; stipe not hairy, sometimes slightly scaly. 
9. CH. VARIANS, Hook. Sp. Fil. ii. 89, t. 103 a. Glabrous; frond long-lanceolate, pin- 
nate; pinnz subentire, pinnatifid or with a few secondary pinnæ ; involucres attain- 
ing §-+ in.—Bedd. Ferns South. Ind. t. 189; Hk. & Baker, Syn. Fil. 127. Pteris 
varians, Wall. Cat. 86. - Pt. cespitosa, Wall. Cat. 90. 
- East Bengal Plain from Assam to Chittagong, general on red Terai soil: ascending 
the Khasi range to 2000 feet alt.—Distrib. Moulmein, Ava, South China, Luzon. Ana- 
mallays (Beddome). 
This is a fern of the plains; common at Dacca. Mr. Baker says its locality is the 
Himalaya ; but I never saw it there, nor is there any example thence at Kew. Mr. Baker 
also does not admit Col. Beddome's locality in Malabaria; but Col. Beddome's figure 
above quoted is so exactly the plant, that I suppose Mr. Baker suspected that Col. Bed- 
dome did not prepare it from his Anamallay plant. 
4. CH. TENUIFOLIA, Swartz, Syn. Fil. 129, 332. Glabrous; frond triangular-lanceolate, 
2-3-pinnate, secondary pinnz numerous; involucres rarely exceeding 3 in. (though 
often confluent in age).—Schkuhr, Crypt. t. 125; Blume, Enum. Pl. Jav. Fil. 137;

alt. 1000 feet.—Distrib. Deccan and Ceylon, Malay Peninsula and Islands, extending to 
China, Australia, New Zealand, Polynesia, Uruguay. 
This fern is also said by Mr. Baker to be confined in North India to the dire, 
there is no example from the Himalaya in the Kew Herbarium, but I have collected it 
in Sikkim. ‘Wall. Cat. 68 has Pellea nitidula, Baker, mixed with it. There isa marked
