apex, terminating near the margin, and as well on the prim, and second, costce 

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

 globose, glabrous, opening irregularly at the summit ; recept. globose, entire, 

 pilose." Karst. Fl. Columb. 1. t. 74. 



Hab. Andes of Bogota, alt. 8-9,000 ft., Karsten. This has the vestiture of Schanschin 

 with an involucre like that of arborea. 



16. C. equestris, Kze. ; u fr, vast, coriaceous, bipinnate ; pinnae long-petiolate, 

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

 apex of the pinna, 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 ; sori near 

 the costule irregular ; cosiee and petioles hairy above ; partial rachises at the base 

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

 #.76. HLSp.l.p.19. 



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

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

 Hk. It is, however, a true Cyathea. 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 1^ in. br., oblong acuminated, quite glabrous ; segments very close-placed, 

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



17. C. calva, Karst. ; jr. ample, tripinnatifid ; rachises naked ; pinnce oblong- 

 lanceolate, H-2 ft. 1. ; pinnl. ligulate acuminate, lower short-stalked, 4-4^ in. 1., 

 | in. br., cut down to a narrow wing ; segm. in. br., faintly toothed ; texture 

 firm ; both surfaces glabrous except the ribs above ; veins 8-10-jugate, forked ; 

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

 p. 175. t. 192. 



Hab. Andes of Columbia. I cannot by the description distinguish from this C.firma,

18. C. vestita, Mart. ; fr, ample, tripinnatifid; rachises stramineous, densely 

 pubescent ; pinnce oblong-lanceolate, 1-1^ ft. 1. ; pinnl. close, sessile, 2|-3 in. 1., 

 -| in. br., cut down to a narrow wing ; segm. close, ligulate, blunt, 1 lin. br., 

 obscurely toothed ; texture thin and membranous ; both surfaces, especially the 

 lower, densely pilose ; veins 9-10-jugate, immersed, forked ; sori minute, cos- 

 tular ; invol. fragile, membranous, pilose, bursting irregularly. Mart. Ic, Crypt,

19. C. pilosa, Baker; fr, ample, tripinnate ; st. densely muricated ; basal 

 scales lanceolate, castaneous, f-1 in. 1. ; rachises stramineous, muricated, those of 

 the pinnae densely shortly pilose ; pinnce 1-1 ft., oblong-lanceolate ; pinnl. ligu- 

 late, 3-3^ in. 1., ^-f in. br., the lower short-stalked ; segm. 1 lin. br., falcate, blunt, 

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

 on the ribs; veins 7-8-jugate, forked; sori minute, costular; invol. fragile, 

 glabrous, bursting irregularly. 



Hab. Andes of East Peru, Spruce, 4729. Midway between vestita and Schanschin. 



20. C. Schanschin, Mart. ; "fr. bipinnate ; st. and rachis sharply aculeated, and, 

 as well as the rachis and veins, strigoso-villous ; pinnl. downy, linear, cuspidato- 

 acuminate, pinnatifid; hies linear-oblong, obliquely rotundate, subcrenulate ;
