CIIEILANTIIKS. 95 



Madras Peninsula, it seems quite confined to that district, and to the 

 mountains of Ceylon, where it has been recently found by the lamented Mr. 

 Gardner. 



36. Ch. Chusana, Hook.; small, root tufted, stipitcs tufted 

 very short 2 — 4 lines long slightly scaly (scales small subu- 

 late) and as well as the main rachis ebeneous glossy plane on 

 one side or furrowed above, frond lanceolate attenuated be- 

 low 3 — 4 inches long rather rigid subcoriaceo-membranace- 

 ous glabrous bipinnato-pinnatifid, primary pinnules petiolate 

 subdeltoid, lower ones opposite and gradually smaller the 

 rest alternate, secondary pinna3 rather distant and as well as 

 the lacinige linear crcnato-lobate or lobato-pinnatifid obtuse, 

 involucres in pairs formed of the inflexed lobules membra- 

 nous and pale only at the edge distinct but copious and ap- 

 proximate. (Tab. CVI. B.) 



Hab. Cliffs, Chusan, Mr. Alexander. — Apparently a very distinct spe- 

 cies from any hitherto published, but allied to Ch. Mysurensis. It differs 

 from it in the small size, broader and shorter primary pinnsp, but espe- 

 cially in the involucres, which are more decidedly inflexed margins of the 

 pinnules, and always in pairs. The stipes, short as it is, is ebeneous, glos- 

 sy, and plane on the upper side, and where it forms the primary rachis it 

 is distinctly furrowed, I have seen this in no collection but that received 

 from Mr. Alexander. 



37. Ch. tenuis, Pr. ; " fronds ovate tripinnate bipinnate at 

 the apex, pinnules sessile oblong obtuse nearly glabrous, up- 

 per ones confluent, sori distinct, rachises and stipes villoso- 

 paleaceous." Presl^ Reliq. Hmnk. p. 65. 



Hab. Mexico, HcBtike. — Presl says nothing about the affinities of this 

 species, and only gives descriptive notes ; " Caudex very short small, clothed 

 with black setas. Stipes 3 inches high filiform terete blackish-brown ; vil- 

 lous with pilifonn articulated brown paleas. Frond an inch and a half long 

 as much wide at the base, below tri- at the apex bipinnate. Pinnae lan- 

 ceolato-oblong, obtuse, subopposite shortly petiolate. Pinnules sessile ob- 

 long obtuse deeply crenate bearing scattered hairs, 2 lines long, 1 broad : 

 upper ones confluent. Rachises blackish brown villous with piliform arti- 

 culated paleae. Sori small distinct, situated in the sinuses of the membra- 

 naceous creuulated involucres." 



Lendigera-group. 

 * Hairy, rarely scaly or chaffy. 



38. Ch. lendigera, Sw.; caudex much creeping villous with 

 brown chaffy hairs, stipites distant a span to a foot long brown 

 and as well as the rachises more especially densely clothed 

 with tawny brown long scarcely chaffy hairs most copious and 

 persistent in the rachises more or less deciduous on the stipes, 

 fronds a sjjan long oblong or ovato-lanceolate subcoriaceous
