parvis, oblanceolatis v. obovato-oblongis, obtusiusculis, apicem versus obscure denticu- 
latis, eveniis, brevissime crassiuscule petiolatis; floribus ad apices ramulorum sessilibus

Summit of Roraima. 
Folia conferta, imbricata, 4-7 lin. longa. Flores 4-4 poll. diam. 
A very distinct species, of which our material is rather imperfect. 
S. MAHUREA EXISTIPULATA, Benth.  Aroie Creek. 
288. TERNSTR@MIACEA ? (inadequate). Path to upper savannah. 
22. SIDA LINIFOLIA, Cav. Атароо В. 
130. BYRSONIMA CRASSIFOLIA, H. B. K., var.? Near house. 
136. TETRAPTERIS? (no fruit). Near house. 
255. TETRAPTERIS RHODOPTERON, Oliv., sp. nov. ; ramulis appresse sericeis; foliis petio- 
latis, obovato- v. oblanceolato-ellipticis, breviter apiculatis, basi cuneatis, utrinque 
tomentello-pubescentibus, supra glabrescentibus; racemis folio brevioribus, sericeis; 
bracteis brevissimis, ovatis, bracteolis medio pedicelli insertis, obovatis v. late ellip- 
ticis, bractea majoribus; calyce 10-glanduloso, sericeo ; ѕататғе alis lateralibus а 
basi divaricatis, coriaceis, nervosis, glabris, rubescentibus, obtusis, integris v. in- 
terdum inzequaliter dentatis. 
Roraima. 
Folia 23-3 poll. longa, 14-13 poll. lata: petiolus 1-1 poll. longus. Bracteole gemi- 
nate, j'5—$ poll longs. Samara alis longioribus 1 poll. longis. 
211. RAVENIA RUELLIOIDES, Oliv., sp. nov. (Plate XXXVIII. A. figs. 1-6); ramulis 
appresse pubescentibus; foliis unifoliolatis, petiolatis, ovalibus, utrinque attenuatis v. 
basi obtusis, apice obtusiusculis, nervo medio utrinque cum petiolo appresse pubes- 
cente ; pedunculis in axillis superioribus 2-vel 1-floris ; sepalis 2 exterioribus majoribus, 
ovatis v. oblongo-ovatis; petalis longe coalitis, tubo coroll: calyce 4—5-plo longiore, 
leviter curvato ; lobis ovatis lanceolatisve ; antheris 2 fertilibus, basi appendiculatis. 
Roraima, upper slope. 
Folia 14-23 poll. longa, 5-12 lin. lata; nervis subtus obliquis, prominulis; petiolo 2- 
3 lin. longo. Flores 1-1} poll. longi; corolla sericea. Calyx sepalis exterioribus 4—4 
poll. longis. Antheræ appendicibus brevibus, reflexis, obtusis, obovatis v. truncatis. 
Closely simulating some Acanthacea, with its opposite, simple (unifoliolate) leaves, and 
long curved corolla-tube, sheathed at the base by the unequal sepals. The reflexed, some- 
what fleshy appendage at the base of the perfect anthers has not, I believe, been observed 
in the two other described species of the genus.
