BOTRYOPLEURON Hemsley 
BOTRYOPLEURON LONGISPICATUM sp. nov. 
Frutex erectus, parce ramosus, circiter 1 m altus, inflores- 
centiis perspicue castaneo-capitato-glanduloso-pubescentibus ex- 
ceptis glaber; foliis coriaceis, nitidis, ovatis ad oblongo-ovatis, 
8 ad 13 cm longis, perspicue acuminatis, acute serratis, nervis 
utrinque 3 vel 4, subtus valde elevatis, arcuato-anastomosantibus; 
inflorescentiis axillaribus, solitariis, spicatis, 10 ad 18 cm longis, 
cum floribus castaneo-capitato-glanduloso-pubescentibus, brac- 
teolis lanceolatis, 4 ad 4.5 mm longis, inferioribus longioribus, 
dentatis; floribus numerosis, confertis, sessilibus, 6 ad 7 mm 
longis. 
An erect, sparingly branched shrub, about 1 m high, glabrous 
except the conspicuously castaneous, capitate-glandular-pubes- 
cent inflorescences, the stems terete, castaneous, smooth, 4 to 5 
mm in diameter, the ultimate branchlets about 2 mm in diam- 
eter, slightly angled. Leaves coriaceous, ovate to oblong-ovate, 
shortly petioled, 8 to 13 em long, 4 to 7 cm wide, narrowed 
upward to the conspicuously acuminate apex, the base rounded 
to broadly acute, the margins coarsely and sharply serrate, the 
upper surface when dry often nearly black, shining, the lower 
surface somewhat brownish; lateral nerves 3 or 4 on each side 
of the midrib, distant, slightly impressed on the upper surface, 
very prominent on the lower surface, arched-anastomosing; 
petioles stout, 2 mm long or less. Inflorescences axillary, soli- 
tary, spicate, 10 to 18 cm long, shortly peduncled, the rachis, 
bracts, and flowers rather conspicuously castaneous-capitate- 
pubescent. Flowers all sessile, numerous, crowded, pale-blue, 
the subtending bracteoles lanceolate, acuminate, 4 to 4.5 mm 
long, the lower ones larger, persistent, distinctly toothed and 
up to 1 cm long. Corolla tube about 5 mm long, castaneous- 
pubescent externally, the lobes ovate, acute or acuminate, 1.5 
to 2 mm long, the tube somewhat hirsute inside in the upper 
part. Calyx lobes lanceolate, acuminate, pubescent, 2 to 3 mm 
long. Stamens exserted, the filaments 8 mm long, somewhat 
ciliate-hirsute in the lower part; anthers ellipsoid, 2 mm long. 
Ovary ovoid-ellipsoid, pubescent, 2 mm in length.
