 very slender, deuudate, 



25. C. microphi/Ua, Mett. ; cmid. 4 ft. higli ; st. and rachises very deciduously 

 forrugineo-tomentose ; fr. 2-3 ft. long, oblong-ovute, acuminate, tripinnate ;

 Per. p. 23 ; Hk. 2nd Cent, of Ferns, t. 1)9. 



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

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

 species of the genus.

 Madagascar, Mauritius, Bourbon, Seychelles, S^-c. Sp. 20-3-i. 



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

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

 ferruginous scales ; fr. bipinnate ; pinnl. sessile, 2-8 in. 1., glabrous or a little 

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

 /o5e5_ oblong-ovate, subfalcate, obtuse, more or less serrated; vivol. fragile, 

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

 Hk. Sp. ]. JO. 23. t. 10. B. and t. 17. A. (lobes more serrated). C. Burkei, Hk. 

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



Hab. S. E. Africa, Natal, Macalisberg, as far as the Zambesi ; Moramballa, alt. 

 3,000 ft., Livingstone, Kirlc (" caudex 4 ft. high"). — The same species, or a close ally, has 

 been gathered on Mt. Kilimanjaro. 



27. C. Mcvnniana, Hk. ; cand. 30 ft. 1. ; st, and rachises pale-brown, glossy, 

 muricate, glabrous ; fr. subcoriaceous, glabrous, tripinnate ; prim, pinme 2 ft. 1., 

 8 in. w. ; second, pinnce ^ in. w., sessile ddong, pinnatifid only towards the 

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

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

 pinnl., 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. Mann. — Quite 

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



28. C. Welivitschii, Hk. ; caud. 20-25 ft. 1. ; 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-muricate, as is the base of the rachis, the 

 rest glabrous ; rachis also castaneous ; fr. 3 ft. and more 1., subcoriaceous, very 

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

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

 dwarfed pinnce, bipinnate ; prim. pinn. 6 in. 1., 1 in. w., sessile, pinnatifid only at 

 the short acuminate apex ; pinnl. and lobes very patent, oblong and oi)tuse, 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- 

 cujishaped (possibly imperfect), surrounding the whole base of the sorus ; costce 

 on both sides densely and subferruginously villous. 



Hab. W. Africa, Island of St. Thomas, in the Bight of Biafra, alt. 3-7,000 ft., Wehvitsch, 

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

 formed by dwarfed pinnae, which extend nearly to the base of the stipes : thus the frouds 

 are subsessile. 



29. C. cameroo7iiana, Hk. ; ^. 1-2 ft. and more 1., paleaceous with appressed, 

 subulate scales at the base, scarcely asperous, and, as well as the rfircA^>(paleaceo- 

 hirsute upwards only) rufo-castancous ; //•. 4 ft. or more 1., 14-1(5 in. w., sub- 

 coriaceo-membranaceous, bipinnate, quite glabrous, above dark green, paler
