278 PROF. OLIVER ON NEW PLANTS FROM RORAIMA. 
Arapoo River. 
Folia rigida 3-14 poll. longa, 5-8 lin. lata; petiolus ad 1 lin. longus. Umbellæ 3-5- 
cephale, pedunculis hispidulis capitulis sepe paullo longioribus. Capitula late cam- 
panulata $ poll. longa atque lata.

49. PSAMMISIA, with glabrous smooth purple-brown stem, ovate-oblong, shortly apiculate 
quintuplinerved leaves of 4 to 6 in., and contracted umbelliform racemes of flowers 
1 in. in length on pedicels of 1-$ in. This is probably Schomburgk's nos. 670, 974, 
of which corollas are wanting in our example. Whether it be Klotzsch's P. guya- 
nensis I cannot say. 
Roraima, upper slope. 
Under the same no. is apparently another Psammisia in early bud, with more broadly 
elliptical leaves and acute calyx-segments.

sessilibus v. subsessilibus, filamentis anthera 3-5-plo longioribus. 
Roraima, upper part of ledge and summit. 
Possibly a distinct species, but, as our Schomburgk specimens are more advanced and 
scarcely in a comparable state, it is better left as above for the present. The leaves are 
only about 23 lines long (in the type 4 lines), minutely setulose-ciliolate. Flowers 1 to 
11 in. in diameter, of vivid crimson. In our type the flowers are on pedicels, of + to 1 in., 
but these may perhaps elongate after flowering.
