96 ? Pugionium GjErtn. 1 — " Sepals deciduous ; lateral saccate at 

 base. Petals linear-oblong. Stamens free, toothless. Siliqua trans- 

 versely elongated, 2-celled ; one cell 1 - seeded ; the other barren 

 smaller ; indehiscent, 2-valved ; valves closely connate with septum, 

 keeled, produced into a dagger-shaped process; each one 2-spinous on 

 both sides, reticulate without ; epicarp only connected with endo- 

 carp by fibres ; stigma simple sessile. Seed horizontal, with a 

 2-lobed strophiole at base ; cotyledons flat accumbent. — A glabrous 

 herb; leaves linear entire half-amplexicaul ; racemes 2 lax" 3 (Deserts 

 of Caspian 4 ). 



V. LUNAEIE^]. 



a. Altssine^:. — Cotyledons generally accumbent. 



97. Lunaria T. — Sepals dissimilar ; lateral saccate at base. Petals 

 obovate unguiculate. Stamens 6, free, 4-dynamous; filaments some- 

 times possessing a tooth (Braclii/pus). Siliqua stipitate broadly 

 elliptical or oblong, much compressed ; style slender erect ; apex 

 capitate obliquely 2-lobed stigmatose ; valves chartaceous or 

 membranous ; septum thin transparent. Seeds co, often few and 

 remote, usually suborbiculate, much compressed, winged at edge ; 

 cotyledons leafy (coloured) accumbent on shorter conical radicle ; 

 funicles elongated, adnate to septum or more rarely free (Bracliy- 

 pus). — Biennial or perennial herbs, slightly pilose; stems branching; 

 leaves alternate entire cordate petiolate ; flowers in terminal ebrac- 

 teate racemes {Europe, Western Asia). See p. 199. 



98. Farsetia Turra. 5 — Sepals imbricated or subvalvate, frequently 

 erect ; lateral more or less, or very slightly saccate at base. Petals 

 long-unguiculate. Staments 6, 4-dynamous ; filaments of smaller 

 sometimes dentate inside. Hypogynous glands 6 ; 4 lateral larger, 

 alternating with shorter stamens. Siliqua of very variable form
