acuminate, with 2 acute basal prongs; disk of 5 erect emarginate lobes, as long as the 
2 ovate ovaries; follicles 2, nearly straight, terete, subparallel, suddenly inflected near 
the apex, seemingly as if they had been there conjoined, black, opake, lenticellate, 
2? in. long, 1 line thick; seeds many, linearly fusiform, i line long, compressed and 
subchannelled on the ventral face, which bears a longitudinal raphe terminating in a 
point by which they are attached to the placenta, striate on the dorsal face; a widely 
spreading sericeous coma of fine soft hairs, 12 lines long, with an outer series of hairs of 
half that length. 
17. TEMNADENIA CORRUGULATA, nob.: volubilis, ramulis tenuissimis: foliis elliptico-oblongis, imo sub- 
acutis, acuminatis, marginibus subrevolutis, undulatis, flaccide chartaceis, utrinque minutissime 
corrugulatis, supra leete viridibus, ad costam nervisque sulcatis, ad basin coste glandula munitis, 
subtus flavide opacis, subscabridulis, costa nervisque fuscis et prominulis, eveniis, petiolo tenui: 
racemis lateralibus, simplicibus, quam folium quadruplo brevioribus; floribus subapproximatis ; 
pedieellis tenuibus, calyce paullulo longioribus; sepalis lanceolato-linearibus, puberulis, intus 
squamula obtusa donatis; coroll tubo cylindrico, parallele nervoso, quam calyx duplo longiore ; 
. segmentis inzequilatere deltoideis, quam tubus dimidio brevioribus, dextrorsum convolutis ; staminibus 
medio tubi insertis; antheris longe cuspidatis, basi tenuiter biaristatis; disci lobis emarginatis, 
ovaria «equantibus : ceteris ut in precedentibus. In Brasilia: v. s. in herb. Mus. Brit. Rio de Janeiro, 
in montibus (Bowie et Cunningham). 
A species closely approaching the preceding. The axils of its slender branches are 3 in. 
apart; leaves 2-31 in. long, 3—14 in. broad, on petioles 5 lines long; raceme 1 in. long» 
with about 10 congested flowers on pedicels 23 lines long; sepals 13 line long; tube of 
corolla 6 lines long, its throat exactly as in the last species; the segments 24 lines long 
and broad. It differs from the preceding in its more corrugulate leaves, not folded at 
the base, in its shorter raceme on a shorter peduncle, smaller flowers, in its erect sepals, 
with a rounded internal scale, and in its longer disk. 
18. TEMNADENIA PARVIFLORA, nob.: Hemadictyon parviflorum, Benth. Pl. Hartw. p. 355. In Nova 
Granada, circa Pandi (Hartweg 1053): non vidi. 
A plant bearing all the appearance of a Prestonia, as Mr. Bentham observed. Its 
scandent branches are softly and rufously tomentous, its axils furnished with many seti- 
form stipules; leaves ovate-oblong, narrowed below the middle, acute at the base, acu- 
minate, softly chartaceous, villous above, sericeo-tomentous beneath, 4-7 in. long, 2-4 
in. broad, on petioles 6-12 lines long ; corymb terminal, on a divided peduncle bearing 
numerous flowers in a densely capitate head 1-3 in. in diameter, on thickish subfasci- 
culated tomentose pedicels 3 lines long; sepals membranaceous, very acuminate, velu- 
tino-tomentose, 21 lines long, each with an inner bifid or 2 simple scales; corolla villous 
outside; tube nearly 3 lines long, its mouth fleshy, without appendages; Segments 
nearly as long as the tube, oblong-lanceolate, glabrous ; stamens seated on a pilose ring 
in the middle of the tube; filaments short; anthers included, the tips scarcely exserted ; 
disk of 5 connate bifid lobes as long as the villous ovaries; follicles less than a foot long. 
clothed with rufo-velutinous hairs; seeds with a long apical coma.
