ments short free 4-dynamous. Siliqua rather large, linear or ellipti- 

 cal-oblong, much compressed, obtuse at both ends, style slender erect ; 

 apex stigmatiferous 2-lobed ; lobes linear erect connate ; valves flat, 

 1 -ribbed, more or less undulate at edge ; septum membranous, 

 2 -lamellate, transversely areolate. Seeds go, 1, 2-seriate, orbicular much 

 compressed winged ; cotyledons accumbent. — Annual herbs, leafy 

 branching, pilose ; leaves dentate or sinuate ; flowers in rather short 

 racemes, pedicels ebracteate, subdeflexed when fruiting {Kirghiz*). 



18. Matthiola E. Br. 2 — Flowers nearly of Cheiranthus ; lateral 

 sepals saccate at base. Petals long-unguiculate. Siliquas elongated, 

 terete or compressed; rarely 2-rnorphous (superior as above) inferior 

 indehiscent subterete (Diptgchocarpus) ; 3 stigmatose lobes of style 

 erect connivent, often thickened or horned externally ; seeds co, 

 1 -seriate compressed, usually marginate-alate ; funicles filiform free. — 

 Herbs or branching shrubs ; hairs stellate ; leaves oblong or linear, 

 entire or sinuate ; flowers 4 racemose ebracteate 5 ( West and South 

 Uurojje, West Asia, North and South Africa*). 



19. Lonchopliora Dur. 7 — Flowers nearly of Matthiola; lateral sepals 

 gibbous at base. Siliqua (of tardy dehiscence) sagittate subligneous 

 4-gonous ; valves rigid, dorsally compressed, produced at base into 

 subulate horns (concave above, or slightly incurved at apex), un- 

 equally transversely septate ; style erect 2-horned ; stigmatiferous 

 lobes erect; horns alternating with valves. Seeds ovate-compressed ; 

 cotyledons more or less obliquely incumbent. — Annual branching 

 herbs ; hairs stellate-tomentose ; leaves linear or oblong superior 

 subentire ; inferior lyrate or sinuate-pinnatifid ; flowers 8 in terminal 

 ebracteate racemes (Algeria*).
