109. Coluteocarpus Boiss. 3 — Flowers nearly of Jlyssus ; sepals 

 equal erect. Siliqua subglobose-inflated vesiculose, hardly dehiscent 

 at apex; valves tumid membranous ; reticulate; mid-rib strong; 

 septum membranous, disappearing above; style short; apex stigmatose 

 capitate. Seeds few immarginate ; funicles adnate to septum, un- 

 thickened at base. — A low subcaespitose glabrous herb ; leaves linear- 

 oblong; radicals crowded, entire or toothed; flowers 4 in short terminal 

 racemes {Alpine Asia Minor 5 ). 



110. Aubrieta Adans. 6 — Lateral sepals usually saccate at* base. 

 Petals nearly of Cheiranthus. Stamens smaller either all enlarged 

 by tooth at base within, or frequently inflated within and laterally 

 subalate with epidermis. Glands lateral large subquadrate. Siliqua 7 

 linear, globose or oblong ; valves unribbed ; septum transparent ; 

 style thin straight, apex capitate stigmatose entire. Seeds go, 2- 

 seriate, immarginate. — Perennial hoary-tomentose subcsespitose herbs; 

 leaves entire or unequal-dentate ; flowers 8 ebracteate in long pedi- 

 cellate few-flowered racemes {Italy, Greece, Asia Minor, Persia 9 ).
