 pilose and squamose ; sori near the costule at the furcature of the veins ; invol. 

 globose, glal)rous, opening irregularly at the summit; incept, globose, 'entire' 

 pilose." — Karst. FL Columh. 1. t. 74. 



Hab. Andes of Bogota, aU. 8-9,000 ft., Karslen. — This has the vestiture of Schanscliin 

 with an involucre like that of arborea. 



16. C. equestris, Kze. ; "fr. vast, coriaceous, bipinnate ; pinnce long-petiolate, 

 lanceolate ; pinnl. remote, alternate, peticilate, confluent into an acuminated 

 aj)ex of the jnnna, lower ones divaricato-reflexed, middle ones divergent, superior 

 ones patent, all oblong-lanceolate, pinnatifid, unequal at the base, acuminated ; 

 lobes falcato-oblong, rather obtuse, serrulate, lower ones soriferous ; sort near 

 the costule irregular ; cosice and petioles hairy above ; partial racltiscs at the base 

 sparingly aculeolate, beneath towards the base hairy." — Kze. in Schk. Suppl. 

 t.7G. Hk.Sp.l.p.ld. 



Hab. Peru, Poeppig. — The author compares this with our C. dkergcns ; but his figure, 

 and a pinna I possess from the author, show a greater resemblance to Ilemitelia guianensis, 

 Hk. It is, however, a true Cyaikea. This was quite unknown to me at the time I pub- 

 lished the Sp. Fil. I have since received a pinna from the late Professor Kunze. It is 

 5 in. 1., nearly 14 in- br., oblorgacumiaated, quite glabrous ; segments very close-placed, 

 7 lines 1. by 3-4 br., quite plane,

 I in. br., cut down to a narrow wing ; scgm. \ in. br., faintly toothed ; "texture 

 hrm ; both surfaces glal)rous except the ribs above ; veins 8-10-jugate, forked ; 

 sori medial ; invol. glabrous, membranous, breaking irregularly. — Fl. Columh. 2.

Hab Andes of Columbia. — I cannot by the description distinguish from this C. fir ma,

 crenulate ; texture membranous ; both sides, especially the lower, densely pilose
