Order XLIL RHAMNACE^. 



By W. Trklkase. 



Woody plants, sometimes spinose or climbing. Leaves alternate or opposite, 

 simple, not lobed, or slightly lobed in some forms of Condalia, entire, denticulate 

 or serrate, not glandular-punctate (but sometimes with surface glands below), 

 with small or caducous stipules. Flowers in reduced axillary cymes or occasion- 

 ally subspicate or thyrsoid, small, mostly greenish, perfect or occasionally dioecious 

 by abortion (in some species of Rhamnus and Gouania), 4— 5-merous, w ith a con- 

 spicuous disk lining a short calyx-tube and sometimes adnate to the ovary. Calyx- 

 segments valvate, usually cristate down the inner face, often deciduous. Petals 

 distinct, inserted on the calyx near the margin of the disk, or in some genera 

 wanting, short-clawed, hooded or with incurved margins. Stamens as many as 

 and alternate with the calyx-lobes, hence in front of and mostly embraced by the 

 petals when these are present, distinct, inserted at or below the margin of the 

 disk ; anthers short, versatile, 2-celled, on more or less elongated filaments. 

 Pistil compound, 2-3-celled, or 1 -celled by abortion, sometimes lobed; ovules 

 anatropous, 1 or rarely 2 in each cell ; style evident, terminal, mostly notched or 

 lobed, with lateral stigmas. Fruit drupaceous, sometimes dry at maturity, or 

 septicidally capsular, the cocci or segments 1-seeded and frecpiently indehiscent ; 

 seeds not arillate, generally with scanty oily albumen ; embryo straight (some- 

 what curved in Retpiosia), usually with broad occasionally green cotyledons. — 

 The tribes readily separable, but the genera often scarcely distinguishable by 

 technical characters alone, though usually differing in habit, inflorescence, or 

 venation of leaves.
