25. CHEILANTHES, EUCHE1LANTUES. 135 



rachis below ; texture subcoriaceous, uppei- surface nearly naked, lower only 

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

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



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

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

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

 vention of M. Naudin, that this is the Nephrodium lano&um of Michaux's Herbarium. 



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

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

 pinnae 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. micropliylla, Swartz ; rhizome slightly creeping ; st. 2-6 in. 1., wiry, 

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

 3-9 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 the 

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

 and glabrous ; sori roundish or elongated ; invol. narrow, pale. Hk. Sp. 2. p. 84. 

 t. 98. A. C. elongate, Willd. Hk. I. c. p. 86. C. pygmsa, Klotzch, Hk. I c. 

 p. 88. /3, C. pubescens, H. B. K. ; rachis tomentose, both surfaces of the frond 

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

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

 aspidioides, Fee. d, C. Moritziana, Kunze ; whole plant larger ; pinnl. often 

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

 ~HL Sp. 2. 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. Tweediana, Hook., C. oltusata, Presl, and 

 C. cucullans, Fe"e, must also rank here. 



21. C. mysurensis, "Wallich ; st. densely tufted, very short, wiry, dark chesnut- 

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

 ovate-lanceolate, tripinnatifid ; pinnce numerous, the lowest opposite, f-1^ in. L, 

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

 pinnatifid pinnl.; texture 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. 95. t. 106. B. 



Hab. Abundant in Tropical Hindostan, but not known in the Himalayas. Foi\nd 

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

 Oldham in Japan. It resembles C. micropliylla 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 ; pinnce 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.
