Hippoman, 251, fig. 48 F. A tree, 18-25 ft. high, glabrous everywhere 
except on the margins of the stipules; twigs slender, perulate at the 
base, scales oblong, obtuse. Leaves short-petioled, membranous or 
thinly papery, oblong-ovate, more or less cuspidately acuminate, base 
cuneate or somewhat rounded, minutely auriculate-cordate, but not 
glandular, at the point of junction with the petiole, margins entire or 
obscurely crenulate-toothed, 24-31 in. long, 1-14 in. wide, dark green 
above, paler beneath ; lateral nerves 7-8 on each side ; petiole slender, 
$-3 in. long, slightly channelled above; stipules large, oblong-lanceo- 
late, acute, } in. long, with ciliate margins, otherwise glabrous, very 
caducous. Spikes terminal on the twigs, 2}-3 in. long, appearing before 
the leaves which sometimes fail to develop, the scaly branch below the 
lateral leaf-bud at the base of the spike 4-2 in. long, with many rather 
lax distinctly pedicelled male flowers above, and usually 2 distinctly 
pedicelled basal female flowers; male bracts small, suborbicular, acute 
or obtuse, denticulate, 2-glandular at the base, each 3—12-flowered ; 
female bracts oblong-lanceolate, acute, } in. long, eglandular, like the 
stipules but smaller and not or obscurely ciliate on the margin, each 
1-flowered ; pedicels in both sexes exceeding the bracts, males distinctly 
articulate, females twice as long as the males in flower. Male: Calyx 
cupular, 2-3-lobulate ; lobes denticulate. Stamens 2, shortly exserted; 
Female: Calyx deeply 3-sect ; lobes wide-triangular, acute, denticulate, 
with a large gland at each sinus. Ovary glabrous, not horned, 3-celled ; 
styles 3, shortly connate at the base. Capsule with a thin leathery 
exocarp and a very thick woody endocarp, slightly 3-dymous, breaking 
up rather tardily into three 2-valved cocci, } in. across; pedicel in fruit 
gin. long. Seeds narrowly ovoid-cylindric, smooth, brown.
