299. Dryopteris Jamesoni (Hook.) C. Chr. comb. nov. — Fig 30 b. 
Syn. Nephrodium Jamesoni Hook. spec. 4: 66. 1862. 
Type from Ecuador, ad ripam fl. Napo, JAMESON nr. 761 (Kew!) a very 
similar plant was collected in Peru, Tarapoto by Spruce nr. 3946 (L). 
A small species closely related to D. semihastata, which it resembles in size, 
colour, pubescence and the auricled upper base ot the pinnz, but the lamina is 
fully pinnate scarcely to the middle, upwards pinnatifid only. Largest leaf seen: 
stipe 9 cm, lamina 17 em long, 4 cm broad below the middle. Stipe and rachis 
rather pilose by long, stiff, simple hairs, between which some very small, stellate 
hairs can be found. Upper surface densely and adpressedly pubescent, coste and 
veins beneath setose by patent setze. Lowest pair of pinne reflexed and considerably 
reduced. Veins in about 3 pairs in the lobe of the larger pinnze, the basal ones 
normally united. Sori inframedial furnished by a setose indusium. 
It is possible that D. Jamesoni is a small variety of D. macrotis, which it re- 
sembles closely in pubescence of the surfaces, the auricled pinnz and other cha- 
racters. BAKER referred it in Syn. Fil. 293 to Nephr. molle, to which it is, of 
course, not at all related. 
223. Dryopteris Warmingii n. sp. — Fig. 30 c. 
Syn. Nephrodium molle var. ; Jamesoni Bak. Fl. bras. 1°: 489. 1870. 
Type from Brazil: Minas Geraes, Lagoa Santa, leg. WanwrNa 1864 (H!) and 
the same from Sao Paulo, Cajurü, REGNELL nr. III. 1449 b. (Rg, W). 
Rhizomate crasso, ad 5 cm alto, 1 cm crasso, squamis brunneis sparse stel- 
lato-ciliatis praedito. Stipitibus fasciculatis. ad 20 cm longis, tenuibus, pilis minu- 
tis stellatis puberulis vel subglabris, supra sulcatis. Lamina 15—20 cm longa, 
ovato-oblonga, sursum in apicem pinnatifidum sensim attenuata, membranacea vel 
firmo-herbacea, atro-viridi. Rachi dense pilosis; pilis simplicibus longioribus pilis 
minutis stellatis intermixtis. Pinnis suboppositis, sessilibus, basalibus reflexis vix 
abbreviatis, medialibus horizontalibus apicibus curvatim ascendentibus, 3—5 cm 
longis, 1—1'/» cm latis, basi superiore distincte auriculatis, acuminatis, grosse loba- 
tis, dense ciliatis, supra pilis simplicibus adpressis subdense strigosis, subtus ubique 
(praesertim ad costas venasque) pilis simplicibus pubescentibus. Lobis contiguis, 
faleatis, obtusis, basali anteriore duplo majore, subacuto. Venis simplicibus, 5—6- 
jugis, basalibus aut anastomosantibus aut ad sinum conniventibus.  Soris infra- 
medialibus, parvis; indusiis parvis, dense setosis, mox deciduis. Sporangiis pilis 
longioribus maxime in pedicellis sedentibus intermixtis. 
I am convinced that this new species is specifically distinct from the Andine 
D. Jamesoni, with which Baker united it. It is true that the two species agree as 
to almost all characters, still our new species is larger, has a larger number of 
veins, the basal pinnz scarcely reduced, and the lamina is generally fully pinnate 
at the lower two-thirds.
