in its mach-petiolated pinnules resembling some species olBemitdia. Candez 18 ft. high, 

 Teiy slender, denndate. 



25. C. microphylla, Mett. ; catid. 4 ft. high ; it. and radiises very deciduously 

 feiTugineo-tomentose ; fr. 2-3 ft. long, oblong-ovate, acuminate, tripinnate ; 

 prim, pinnw sessile, broad-oblong, acuminate ; second, ones similar to them but 

 smaller, crowded ; pinnl. small, scarcely 2 lines ]., ovato-oblon?, deeply pinna- 

 tifid ; lobes oblong, obtuse, single-veined, entire ; soriis solitary at the base of the 

 veinlet ; invol. globose, breaking irr^nlarly into 3-4 portions. — Melt, in Lechl. F. 

 Pa-, p. 23 ; Ml. 2nd Cent, of Ferns, t. 99. 



Hab. Andes of Pern and Ecuador, Lechler, Jameson, Spruce. — A remarkable mi 

 most distinct species, with very compound fronds, and the smallest pinnules of any 

 species of the genus. 



+t Species of tropical and subtropical Africa, including the adjacent islands, 

 Madagascar, MatarMus, Bourbon, Sa/cheUes, 8{C. Sp. 26-34. 



26. C. Dregei, Kze. ; unarmed, or only rough with small tubercles at the base 

 of the_ St., and there paleaceous with rather large, lanceolate-subulate, glossy, 

 feiTuginous scales ; fr. biplunate ; pinrd. sessile, 2-3 in. 1., glabrous or a little 

 arachnoid at the base beneath, narrow-oblong, acuminate, deeply pinnatifid ; 

 Idies ^ oblong-ovate, subfalcate, obtuse, more or less serrated ; intol. fragile, 

 opening at the top and forming a cup with a small slightly irregular margin. — 

 Hh. Sp.^.p. 23. t. 10. B. and t. 17. A. (lobes more serrated). C. Burkei, Hi. 

 Sp. 1. t. 17. B. ; lobes of the pinnules rather broader. 



Hab. S. E. Africa, Natal, Macalisberg, as fer as the Zambesi ; Morsmballa, alt. 

 3,000 ft., livingstone, Kirk (" candex 4 fu high"). — The same species, or a close ally, has 

 been gathered on Mt. ^Kilimanjaro. 



27. C. Manniana, Hk. ; caud. 30 fl. 1. ; st. and rachises pale-brown, glossy, 

 muricate, glabrous ; fr. subcoriaceous, glabrous, tripinnat« ; prim, pinnae 2 ft. 1., 

 8 in. w. ; second. pintUB ^ in. w., sessile oblong, pinnatifid only towards the 

 narrow acuminated apices ; pinnl. narrow-oblong, falcate, acute, serrated ; veins 

 forked, not prominent ; sori rather large, few, mostly on the lower half of the 

 phuil., and mixed with ovate, fringed scales; invol. lax, deep-cupshaped, but 

 breaking down at the margin, and subpersistent. 



Hab. Fernando Po and Cameroon Mountains, alt. 3—4,000 ft., G. Mcmn. — Quite 

 different from any other tropical African Oyathea I am acquainted with. 



23. C. Wdimtscha, Hk. ; caud. 20-25 ft. L ; St. scarcely any (2-3 in. 1. in 

 my specimens), as thick as a swan's quill, castaneous, paleaceous, with large, 

 subulate, firm, glossy scales, tuberculato-mnricate, as is the base of the rachis, the 

 rest glabrous ; rachis also castaneous ; fr. 3 ft. and more ]., subcoriaceous, very 

 dark-green and slightly hair)- above, paler and more villous with spreading 

 hairs beneath, ovato-lanceolate, contracted below and there hearing numerous 

 dwarfed pinnae, blpLnnate ; prim. pinn. 6 in. L, 1 in. w., sessile, pinnatifid only at 

 the short acuminate apex ; pinnl. and lobes very patent, oblong and obtuse, sub- 

 falcate, strongly crenato-serrate ; veins prominent beneath, forked ; sori mostly 

 near the base of the pinnl. at the forking, and near the costule ; invol. shallow- 

 cnpshaped (possibly imperfect), surrounding the whole base of the sorus ; costae 

 on both sides densely and subferrugiuously villous. 



Hab. AV. Africa, Island of St. Thomas, in the Bight of Bia&a, alt. 3-7,000 ft., WeJicitsA, 

 n. 66, G. Mann. — Remarkable for the contraction of the lower portion of the frond, 

 formed by dwarfed pinnse, which extend nearly to the base of the stipes : thus the fronds 

 are subeessile. 



29. C. camerooniana, Hk. ; si. 1-2 ft. and more 1., paleaceous with appressed, 

 subulate scales at the base, scarcely asperous, and, as well as the rachis (paleaceo- 

 hirsute upwards only) nifo-castaneous ; fr. 4 ft. or more 1., 14-16 in. w., sub- 

 coriaceo-membranaceous, bipumate, c^nite glabrous, above dark green, paler
