4. CYATHEA. 19 



scales, acuminate, frondose at the summit ; fr. ovato-lanceolate, 12-14 ft. 1. l>y 

 C ft. w. ; pinnl. 4-5 in. 1., from a broad base lanceolate ; lobes oblong, margins 

 recurved, penniveined ; veins forked, their branches clavato-incrassate at the 

 apex, terminating near the margin, and as well on thejPrtJV. 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. 14,400 ft., Karsten. Apparently allied to C. arborca, var. 

 pcdlida, and to C. Sckanschin ; but, unfortunately, no essentially distinguishing features 

 are pointed out. 



1G. C. equestris, Kze. ; <r '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 ; costce and petioles hairy above ; partial rachises at the base 

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

 fc 70. Hk. Sp. 1. p. 19. 



Hab. Peru, Poeppig. The author compares this with our G. diveryens ; but his figure, 

 and a pinna I possess from the author, show a greater resemblance to Hemiteiia Gma- 

 neiisis, Hk. It is, however, a true CyatJiea. This was quite unknown to me at the time 

 I published 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. Beyrichiana, Pr. ; st. aculeate and at the base clothed with long, 

 brown, chaffy hairs ; fr. ample, subcoriaceous, bipinnate ; rachises and costa 

 more or less downy ; prim.pinnce 1^ ft. 1. \pinril. 3-3 in. 1., sessile, oblong, acu- 

 minated, deeply, nearly to the costa, pinnatifid ; lobes linear-oblong, subfalcate, 

 the margins obscurely serrate, recurved ; sori rather copious and close to the 

 costule, not extending to the margin ; invol. dark-brown, firm, and persistent, 

 lax, often splitting at the back and spreading or bifid, to all appearance covering 

 the whole eorus in an early stage. Hk. Sp. I. p. 21. and Ic. PL t. 023. Am- 

 phicosmia, Moore. 



Hab. Brazil. I scarcely think it correct to refer this to the Amphicosmia section of 

 Hemiteiia, as Mr. Moore has done ; but, indeed, both the genera and species of Cyathe- 

 aceous ferns present great difficulties in the way of accurate determination. Beyrich 

 looked upon this Fern as an Alsophila ; but that it cannot be, 



IB. C. vestita, Mart. ; "fr. bipinnate ; st. and rachis shortly and sharply 

 aculeated ; partial racMs and veins with rusty hairs ; pinnl. pubescenti-villous 

 beneath, linear-acuminate, deeply pinnatifid, the lobes falcato-lanceolate, acute, 

 crenulate with G-10 sori in each." Mart. Ic. PL Cr, p. 75. t. 52, C. Delgadii, 

 Pohl (Moore'). 



Hab. Brazil, Martins, PohL, Gardner, n. 1907 (Moore). There seem to be no tangible 

 characters to mark this species, if such it be. 



19. C. hirtula, Mart. ; "fr. bipinnate ; st. sharply aculeate and the rachis villous 

 with brownish hairs and sparingly paleaceous ; pinnl. slightly pubcscenti-hirsute 

 on both sides, linear, acute, pinnatifid ; the lobes ovato-lanceolate, rather obtuse, 

 subcrenulate or entire ; sori in each segment few and basal." Mart. 1. c., p. 70. 

 t. 53. Hk. Sp. p. 20. . - 



Hab. Brazil, Martins. Guiana, R. Sclwmburgk, n. 1124 (according to Kunze and 

 Moore). Unknown to me. 



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

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

 acumiuate, pinnatiiul ; lobes linear-oblong, obliquely rotundate, subcrenulate ;
