278 PROF. OLIVER ON NEW PLANTS FROM RORAIMA. 



Arapoo River. 



Folia rigida f-lf poll, longa, 5-8 lin. lata ; petiolus ad 1 lin. longus. Umbellse 3-5- 

 cephalae, pedunculis hispidulis capitulis ssepe paullo longioribus. Capitula late cam- 

 panulata f poll, longa atque lata. 



247. Erechthites hleraciifolia, Raf. 5400 ft. 



10. Stifftia condensata, Baker. Near Waetipoo M. 

 314, 346. Centropogon l^evigatus, A. DC, var. ? Ledge 5400 ft. 



77. C. surinamensis, Presl ? 3500 ft. 



56. Psammisia ? sp. (inadequate). 5400 ft. 



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 ^-f 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. 



109. Notopora Schomburgkii, Hook. f. 5400 ft. 



243. Sophoclesia aff. S. sabscandenti (ovario glabro). Ledge 7300 ft. 



329. (333?). Vaccinium, an V. floribundum, H. B. K. ? (V. poly stachy urn, Benth.). 



Top and ledge. 

 326 365. Vaccinium, an V. floribundum, H. B. K., var.? Top. 



308. Ledothamnus guyanensis, Meissner in Mart. Fl. Bras. vii. 172. (Plate XLIV. A. 

 figs. 1-6.) 172. Var. minor ; foliis minoribus imbricatis acutis ciliolatis, fioribus 

 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 2^ lines long (in the type 4 lines), minutely setulose-ciliolate. Flowers 1 to 

 lj in. in diameter, of vivid crimson. In our type the flowers are on pedicels, of | to 1 in. r 

 but these may perhaps elongate after flowering. 



Label missing. Befaria guianensis, Klotzsch. 



310. Befaria aff. B. resinosce, Mutis (sepalis obtusioribus). (2 forms.) Top. 

 With no. 333. Pernettya, near P. parvifolia, Benth., and allies (in fruit). 

 103. Gaultheria cordifolia, H. B. K. 5400 ft. 

 332. Gaultheria aff. G. vestitce, Benth. (pedicellis longioribus). Top. 

 137. Lucuma rigida, Mart. & Eichl. 5400 ft. 

 108. Grammadenia lineata, Benth. 5400 ft. 

 36. Ditassa taxifolia, Decne. Arapoo R.
