1. H. integrifolia, Planch, in Ann. Sci. Nat. 3me. ser. 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, li-2J 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 f lin. long, puberulous on back. Filaments glabrous ; anthers 

 puberulous. Ovary compressed, pubescent, the stalk lengthening 

 as the fruit ripens. Samara |-1 in. broad, notched at the top, the 

 broad wings beautifully veined ; stalk J- J 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. PI. 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 

 sepals ; filaments free, not incurved ; anthers bluntly and shortly 

 ovate. Torus densely hairy. Fertile : Calyx and torus as in male ; 

 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 

 and margins. Drupe fleshy, ovoid to globose, sometimes slightly 

 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 

 with acuminate apex, and unequal at the base, margin entire or 

 serrate, penniveined, 1- or 3-nerved. Stipules lateral, free, caducous.
