Viuliis helow ; texture subcoiiaceous, upper surface nearly naked, lower only 

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

 Gray, Manual, p. 592. C. lanosa, JFai^, oldest name. 



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

 in tlie "Species Filicuui," the C. vcslita there given being our C. laniif/inosa. 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 lanosum of Michaux's Herbarium. 



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

 pilose, brittle ; /"r. G-12 in. 1., l|-2 in. br., linear-oblong, tripinnatifid ; lower 

 pinnce 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. iSp. 2. p. 93. t. 1 10. B.

 habit, larger, and more hairy. 



20. C. microph)/lla, Swartz ; rhizome slightly creeping ; st. 2-6 in. 1., wiry, 

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

 3-9 in. 1., 2-3 in. br., ovate-lanceolate, hi- 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 ; rachis usually naked ; both surfaces green 

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

 —Hk. Sp. 2. p. 85. t. 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 G. Tweediana, Hook., C. ohlusata, Presl, and 

 C. cucullans, Eee, 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. 1., 1^-3 in. br., 

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

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

 pinnatitid 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. Sj). 2. p. 94. t. 100. A.

 more scaly.
