equal at base. Siliqua elliptical or subovoid, emarginate, laterally 

 much compressed; style very short; apex stigmatose minutely 

 capitate ; valves keeled subalate ; septum oblong membranous. 

 Seeds few (2-6) in each cell, ovate immarginate ; funicles slender, 

 adnate to septum at base. — An annual herb, rather thin glabrous 

 glaucescent ; inferior leaves petiolate ; cauline cordate-amplexicaul ; 

 flowers 1 in finally elongated racemes ; pedicels slender, ebracteate 

 (Sici/f). 



159. Campyloptera Boiss. 3 — Sepals nearly erect; lateral gibbous 

 at base. Larger stamens dilated or connate at base. Siliqua 

 dimorphous cymbiform ; edges incurved unequally winged ; some 

 1-celled, 1-seeded ; others 2-celled. Seeds 1, 2 in each cell, descend- 

 ing ; funicles free. — A branching glabrous herb ; 4 lower leaves 

 opposite sessile amplexicaul entire ; flowers 5 in terminal racemes 

 {Syria 6 ). 



160. Menonvillea DC. 7 — Sepals scarcely dissimilar; lateral sub- 

 saccate at base. Siliqua substipitate dorsally compressed, 2- 

 scutate ; valves convex at back ; sides broadly winged. Seeds soli- 

 tary in each cell ; cotyledons incumbent. — Erect herbs or under- 

 shrubs, glabrous ; leaves linear ; radical more or less dentate ; caul- 

 ine entire ; flowers 8 ebracteate in frequently elongated racemes, 

 simple Or sparingly branching {Peru, Chili 9 ). 



161. Hexaptera Hook. 10 — Sepals uniform subequal. Petals con- 

 tracted at base. Stamens 6 ; longer 4 connate in pairs or free. 

 Siliqua inserted in unthickened receptacle, shortly stipitate dorsally 

 compressed, 6-winged ; style cylindrical ; apex stigmatose capitate ; 

 valves much contracted at suture, 3-winged ; dorsal wing 1 ; lateral
