opposite, sometimes ternate, petioled, entire, simple (in IlUgera 8-folio- 

 late) ; stipules 0. Flowers bracteotate at the base, in tbe tribe Gyrocar" 

 pese cyraose ; in the Conihreteas spicate or racemose (the racemes often 

 panicled) ; often poljgamo-monoecious. Galyx-tuhe adnate to the ovary 

 and produced above it (sometimes to a great length), the limb of 4-5 

 (rarely 4-7) valvate lobes. Petals 4-5 or 0, (raiely 6-7). Stamens 4-5 

 or 8-10, inserted on the calyx; (in the Gyrocarpeoe the filaments -with 

 staminodes attached at the base, and the antliers dehiscing by recurved 

 lateral valves). Ovary inferior, 1-celled ; style simple ; stigma simple or 

 in IZZ/grem sinuate, almost lobed ; ovules 1-7 (usually 2-3), pendulous 

 from the apex of the cell. Fniit coriaceous or drupaceous, generally 

 indehisceut, ovate, angular or very commonly winged ; in Calycopteris 

 and Gyrocarpus crowned by the greatly enlarged calyx. Seed 1, with- 

 out albumen ; cotyledons in Terminalia and others convolute ; in Com- 

 hretiivi and others plano-convex. Distrib. Species about 320, in the 

 tropics of the whole world ; and in S. Africa outside the tropics.
