25. CHEILANTHES, §§ EUCHEILANTUES. 135 



rachis below ; texture subcoriaceous, upper surface nearly naked, lower only 

 slightly hairy, not densely matted ; rachis thinly tomeutose ; sori copious. — 

 Gray, Manual, p. 592. C. lanosa, Watt, oldest name. 



Hab. Delaware and Penusylvauia southward to New Carolina. — This is not described 

 in the "Species Filicum," the C. vestita there given being our C. Immginosa. We owe 

 the unravelling of the synonymy to Prof. Eaton, who has ascertained, through the inter- 

 vention of M. Naudin, that this is the Nephrodmm lanosum of Miohaux's Herbarium. , 



10. C. pilosa, Goldm. ; st. tufted, 2-4 in. 1., flexuose, dark chesnut-brown, 

 pilose, brittle ; fr. 6-12 in. 1., 1^-2 in. br., linear-oblong, tripinnatifid ; lower 

 pinncB distant, |-1 in. 1., deltoid, cut down to the rachis below into oblong 

 pinnl., 3-4 lin. 1., 2 lin. br., deeply lobato-pinnatifid ; texture herbaceous ; 

 rachises and both surfaces glandulose-pilose ; sori copious, slightly confluent. — 

 C. MacLeanii, Hk. Sp. 2. p. 93. t. 1 10. B. 



Hab. Andes of Peru. — This comes nearest the true C. vestita, but is very flaccid in 

 habit, larger, and more hairy. 



20. C. rrAcrophylla, Swartz ; rhisome slightly creeping ; St. 2-6 in. ]., wiry, 

 flexuose, polished, dark chesnut-brown, tomentose below when young ; fr, 

 S-9 in. 1., 2-3 in. br., ovate-lanceolate, bi- or tripinnatifid ; pinnce in numerous 

 nearly opposite pairs, the lowest 1-2 in. 1., |-f in. br., lanceolate Or tending 

 towards deltoid ; pinnl. linear-oblong, entire or subdeltoid, and cut down to thd 

 rachis below ; texture subcoriaceous ; rachis usually naked ; both surfaces green 

 and glabrous ; sori roundish or elongated ; invol, narrow, pale. — Hk.Sp.'Z.p. 84. 

 t. 98. A. C. elongata, Willd. Hk. I. c. p. 86. C. pygmsea, Klotxch, Hk. I. c. 

 p. 88. — ;8, C. pubescais, II. B. K. ; rachis tomentose, both siirfaces of the frond 

 pubescent. Hk. Sp. 2. p. 93. — y, O. micromera, Link; pinnce numerous, close, 

 spreading, pinnules ovate-oblong, entire or nearly so ; invol, subcontinuous. C. 

 aspidioides, FSe, — S, G. Moritziana, Kunze ; whole plant larger ; pinnl. often 

 i in. 1., cut down nearly to the rachis for the lower two-thirds into oblong segm. 

 —Hk.Sp.i.p. 85. «. 99. B. 



Hab. Tropical America, from Mexico and the West Indies southward to Peru. — A very 

 variable plant, and it is to be feared that C. Tweedicma, Hook., 0. obtmata, Presl, and 

 C. cucullams, F^e, must also rank here. 



21. C. »jys«reresj«, Wallich ; af. flensely tufted, very short, wiry, dark chesnut- 

 brown, polished, fibrillose below when young ; fr. 3-12 in. 1., lf-3 in. br., 

 ovate-lanceolate, tripinnatifid ; pinnae numerous, the lowest opposite, \-\\ in. 1., 

 lanceolate-deltoid, cut down to the rachis into numerous linear-oblong inciso- 

 pinnatifid pinnl.; tessture herbaceous when young, subcoriaceous when, mature; 

 rachis polished, chesnut-brown, slightly fibrillose, both surfaces naked ; sori 

 small, roundish, distinct or slightly confluent. — Hk. Sp. 2. p, 94. t, 100. A; 

 C. Chusana, Hk. Sp. 2. p, 96. t. 106. B; 



Hab. Abundant in Tropical Hindostan, but not known in the Himalayas. Found 

 also in Ceylon, West China, and at Canton and Chusan, and gathered lately by Mr. 

 Oldham in Japan. — It resembles C. microphylla very closely, but the stipe is shorter and 

 more scaly. 



22. C. fragilis, Hk. ; st, densely tufted, not more than 1-2 in. 1., strong, 

 erect, tomentose and fibrillose ; fr. 6-12 in. 1., 2-4 in. br., ovate-lanceolate, 

 bipinnatifid ; pinn(e numerous, alternate, the lowest 1-2 in. apart, 1-2 in. 1., 

 \ in. br., oblong-lanceolate, cut down to the rachis below into numerous linear- 

 oblong, blunt, sinuato-crenated lobes ; texture herbaceous ; rachises bright-brown, 

 tomentose, both surfaces green and naked except the midrib beneath ; sori 

 small, roundish or subcontinuous ; invol. pale-brown, membranaceous. — Hk. Fil. 

 Exot. t. 96.
