1. H. integrifolia, Planch. in Ann. Sci. Nat. 3me. sér. x. 266. 
A large spreading deciduous tree 50-60 ft. high, with ash-grey (brown- 
violet, according to von Doering) pustular bark; shoots glabrous. 
Leaves elliptic, acuminate, base rounded or cordate, margin entire 
_ (often serrate on seedlings and shoots), 3-5 in. long, 14-23 in. wide, 
glabrous, upper face shining, midrib prominent beneath, veins 5-7 
on each side, ascending and uniting below the margin. Flowers 
in short branched inflorescences at the scars of fallen leaves, usually 
male and hermaphrodite, the latter above. Sepals concave, obovate, 
about ? lin. long, puberulous on back. Filaments glabrous; anthers 
puberulous. Ovary compressed, pubescent, the stalk lengthening 
as the fruit ripens. Samara 3-1 in. broad, notched at the top, the 
broad wings beautifully veined; stalk }-} in. long, jointed in the 
middle.—Planch. in DC. Prodr. xvii. 164; Hook. f. Fl. Brit. Ind.

2. CELTIS, Linn.; Benth. et Hook. f. Gen. Pl. iii. 354. 
Flowers polygamous, the fertile generally hermaphrodite. Male: 
Calyx membranous, deeply divided, sometimes to the base, into 5, 
rarely 4, concave imbricate segments. Stamens as many as the

stamens smaller than in male. Ovary sessile; ovule pendulous 
from the apex, anatropous; style central, 2-partite, branches 
undivided or 2-fid, densely papillose-stigmatose on the upper face

keeled ; endocarp bony, rough, sometimes keeled. Embryo curved ; 
cotyledons very broad, applied face to face.—Trees or shrubs, 
deciduous or evergreen, unarmed in tropical African species. Leaves 
alternate, short-stalked, generally more or less coriaceous, often
