 breviter adpresse hirtulis, pilis imo scabridule bulbosiSj nervis temiissimis utrinque circa 15 subpatule 

 diraricatis, subtus flavide opacis, dense et breviter tomentosis, costa nervisque prominulis molliter

 brevioribus : racemo solitario, ad nodos laterali, quam folium 2pIo longiore ; pedunculo valido, pro 

 tertia parte basali nudo, superne valde iacrassato et alternatim plurifloro ; pedicellis brevibus, sub- 

 reflexis, puberulis, bracteis ovalibus tomentosis suffultis ; sepalis subparvis, lanceolatis, puberulis ; 

 corolla nondum explicata flavida, undique molliter niveo-lanata ; tubo cyliadrico medio angustipre,

 peduncle IJ line thick below, 2 lines thick above, bare at the base for 1 in. ; flowers 

 alternate, 3 lines apart, on pedicels 2 Hues long, supported by oval bracts 4 lines long ; 

 sepals 2J lines long ; corolla in bud 1-| in. long ; tube 11 lines long ; follicles (in a very

A climbing species with glabrous branches, and patent branchlets hispidulous towards 

 their base, with remote axUs ; leaves oblong-ovate, narrowed and cordate at the base, 

 acuminate, rigidly membranaceous, glabrous above, with about 11 pairs of slightly 

 arching and very slender reticulated veins, ciliate on the margins, paler beneath, hispid 

 along the midrib and nerves, 3^-5 in. long, li-2J in. broad, on petioles 6-10 lines long, 

 the upper pairs shortest ; raceme axillary, erect, on a short peduncle, with many flowers 

 on rigid puberulous pedicels 2 lines long, supported by narrow, linear-lanceolate, long- 

 acuminate bracts with ciliate margins 11 lines long ; sepals ovate-lanceolate, long-acumi- 

 nate, margins cihate, 3f lines long, each with a small ovate inner scale ; tube of corolla 

 12 lines long, cylindrical below, subcampanulate above the middle; segments sub trapezoid 

 ovate. If line long ; disk of 5 truncate-ovate concave lobes, shorter than the ovaries ; 

 follicles torulose, glabrous, 4 in. long, 2^ lines broad ; seeds as long as the coma. 



A species probably belonging to Laseguea.
