428 LXVIII. SAPOTACEiE [Hejjtonuf 



young shoots and young leavf^s clotlied with delicate pubescence. L. thickly coriaceous^ 

 1-1^ in. long, entire, obovate, narrowed into a short petiole. FJ. small, greenish-yellow 

 or whitish, almost sessile in compact axillary clusters. Corolla-tube short, lobes rounds 

 spreading, stamens inserted on the edge of the tube, filaments long exserted, anthers 

 dehiscing outwai-dly. Ovary clothed with 2-arnied hairs, 1-celled, with rudimentary 

 dissepiments at the base, ovules 5-7, basal. Vi\ fleshy, usually one-seeded. This 

 genus, as showai by Radlkofer, belongs to f^apotacecc. 



Order LXIX. EBENACE^. aen. PL ii. 662. 



Trees or shrubs. L. alternate, rarely subopposite, entire, stipules 0. FL 

 usually dioecious, calyx gamosepalous, persistent and nsually enlarged in fr. 

 Stamens 2-16 times the number of corolla-lobes, filaments often paired or in 

 bundles, styles 2-8, cells as many or twice as many as the styles. Seeds 

 pendulous, a small asile embryo in a horny often ruminated albumen. 



Fl. 4-5-merous, ovary 4-5- or 8~10-celled . . . .1. Diospyros. 

 ri. mostly 3-merous, ovary 3- or 6-celled .... 2 Maba. 



Like Sapotacce^ the Ebonies have concentric bands of w^ood parenchyma, appearing 

 like transverse bars across the medullary rays, but they are often extremely 

 fine and dilficult to see. The wood-fibres have minute bordered j)its. The wood of 

 many species is dark grey, and in the stems of some species "when old, irregular masses 

 of jet-black w^ood are formed, sometimes alternating w^ith strata of lighter coloured 

 wood. In this jet-black wood (Ebony) the vessels and wood fibres are filled with a 

 black substance, the nature and origin of which is not yet fully understood. 



1. DIOSPYROS, Linn. ; Fl. Brit. Ind. iii. 553. 



Trees, rarely shrubs. L, alternate, entire, subopposite in a few species. 

 Fl. in most species white, mostly 4-, in some species 5-, rarely 6-merous, 

 corolla-lobes usually overlapping to the right. (J and ? nsnally on separate 

 trees, often polygamous, the ? fl. larger, with the calyx usually divided nearly 

 to the base. Stamens ordinarily 8-52, often in pairs or otherwise connate, 

 anthers basifixed, in most species linear, staminodes in $ ii., ovary 4-10-celled. 

 I^r. generally supported by the enlarged calyx, rind coriaceous, seeds embedded 

 in soft or viscid pulp. Embryo small in horny albumen, which often is rumi- 

 nated by the intrusion of the dark coloured testa. Species 180, tropics of the 

 whole world, a few species beyond the tropics.
