5. AMBLYANTHERA OVATA, nob.: ramis simplicibus, scandentibus, flexuosis, fistulosis, pallide brunneis, 
pubescentibus ; axillis remotis: folis late ovatis, imo rotundatis, integris et subplicatis, aut vix 
cordatis, apice emarginatis aut subito in acumen acutum constrictis, supra fusco-viridibus, opacis, 
breviter adpresse hirtulis, pilis imo scabridule bulbosis, nervis tenuissimis utrinque circa 15 subpatule 
divaricatis, subtus flavide opacis, dense et breviter tomentosis, costa nervisque prominulis molliter 
hirsutis, venis conspicue transversis et reticulatis; petiolis tenuibus, puberulis, quam limbus 3-4plo 
brevioribus : racemo solitario, ad nodos laterali, quam folium 2plo longiore ; pedunculo valido, pro 
tertia parte basali nudo, superne valde incrassato 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 cylindrico medio angustiore, 
superne vix inflato. In Bolivia? v. s. in herb. meo, sine loco. 
A distinct species, with branches 1 line thick, the axils 4-6 in. apart; leaves 22-24 
in. long, 13—2 in. broad, on slender petioles 8-9 lines long; raceme 4 in. long, on a stout 
peduncle 1j line thick below, 2 lines thick above, bare at the base for 1 in.; flowers 
alternate, 3 lines apart, on pedicels 2 lines long, supported by oval bracts 4 lines long; 
sepals 23 lines long; corolla in bud 13 in. long; tube 11 lines long; follicles (in a very 
immature state) densely niveo-tomentous. 
6. AMBLYANTHERA CILIATA, Müll. Fl. Bras. xxvi. p. 146; Linn. xxxi. p. 449: Echites ciliata, Stad. Bot. 
Zeit. 1861, p. 32; A. DC. Prodr. viii. p. 459. In prov. Bahia, ad Caiteté: non vidi. 
A. elimbing species with glabrous branches, and patent branchlets hispidulous towards 
their base, with remote axils; 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, 31—5 in. long, 11-21 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 oyate-lanceolate, long-acumi- 
nate, margins ciliate, 32 lines long, each with a small ovate inner scale; tube of corolla 
12 lines long, cylindrical below, subcampanulate above the middle; segments subtrapezoid 
ovate, 1j line long; disk of 5 truncate-ovate concave lobes, shorter than the ovaries; 
follicles torulose, glabrous, 4 in. long, 24 lines broad; seeds as long as the coma. 
A species probably belonging to Laseguea.
