256 NATURAL HISTORY OF PLANTS. 



seed descending, obovate-compressed,immarginate smooth; cotyledons 

 incumbent ; funicle adnate to wall. — Small thin branching herbs, 

 quite glabrous ; leaves linear or oblong, sessile ; cauline cordate at 

 base ; flowers 1 (minute) racemose ; pedicels ebracteate filiform, when 

 fruiting recurved (Caspian, Songaria 2 ). 



70. Dipterygium Dcne. 3 — Sepals short, subequal at base. Petals 

 shortly unguiculate. Stamens 6, free ; filaments short. Siliqua 

 elliptical-oblong, compressed subdrupaceous ; exocarp dilated into a 

 lax thin vertical membrane ; endocarp nucamentaceous, unequally 

 rugose outside, 1 -seeded ; 4 style subulate; apex capitate stigmatose. 

 Seed ascending, immarginate ; embryo coloured ; cotyledons incum- 

 bent, concave. — A virgate undershrub, divaricately branching ; 5 leaves 

 small,- alternate, petiolate, ovate or oblong, acute entire ; flowers 

 racemose ; pedicels bracteolate, slender, short, erect, when fruiting 

 pendulous (Arabia, Nubia, West Indies*). 



71. Tauscheria Fisch. 7 — Sepals subequal at base. Stamens 6, 

 free 4-dynamous ; glands small, interposed. Siliqua shortly ovate- 

 cymbiform, unsymmetrical, arcuate-ovate, crustaceous in centre, some- 

 times convex, sometimes with margin involute concave alate ; apex 

 tapering into a subulate style. Seed 1, descending from near apex of 

 cell ; cotyledons incumbent. — An annual branching herb, glabrous 

 glaucous, or pilose; leaves entire; cauline amplexicaul; flowers 8 ebracte- 

 ate in simple axillary and terminal racemes ; pedioels decurved when 

 fruiting [Central Asia, North India*). 



72. Moriera Boiss. 10 — Sepals equal at base. Stamens free, nearly
