JAMESONIA CINNAMOMEA. Kze. 
Robusta pinnata, stipite breviusculo compresso canaliculato, 
rachide crassa densissime ferrugineo-lanosa, pinnis omnibus 
secundis imbricatis rotundatis basi cordatis coriaceis supra 
convexis lateribus deflexis marginibus insigniter revolutis 
longe ciliatis costa subtus setoso-paleaceis, soris linearibus 
convolventibus discum subtus totum obtegentibus. 
Jamesoniana cinnamomea. Kunze, in Bot. Zeit, 1844, p. 738: ; 
Has. El Equador. Abundant on the eastern flank of Cotopax!, 
at an elevation of 1,400 feet above the sea-level, growing m 
company with Culcita, Ribes frigidum, &c. Prof, W. Jamesim, 
m. 12 ; Columbia, Flartweg, n. 1516. 
: A very different species from Jamesonia pulchra, figured 
in Icones Filicum, tab. 178. And since our figure was pte 
pared we find that Professor Kunze has published the 
de Berlin,” under the name of J. cinnamomea, together with 
J. scalaris (Caraccas, Linden, n. 519), J. verticalis (Columbia, 
Hartweg, n. 1504), and two species “fronde pinnata,” namelY, 
J. paleacea (Caraceas, Linden, n, 505), and J. hispidula 
(Caraceas, Moritz, n, 72), making six species in all. Tome@ 
further examination of this beautiful genus seems to lead to the 
conclusion that its affinity is with Gymnogramma; for the normal 
orm of the sori appears to be oblong or linear, though generally 
roniluent, and frequently covering the whole disc of the pinnule 
beneath. The Present species is much larger and stoutel 
than J. pulchra; the silky wool is altogether of a deep i 
Tuginous brown colour, shorter and more compact ; the pinn® 
are singularly thick and coriaceous, and all point forwards, and 
mere orless downwards, and imbricate each other. Veins forked
