shorter. Petals large erect long-unguiculate. Stamens 6, free toothless 

 inserted on much thickened shortly clavate glandular receptacle. 

 Siliqua linear-elongated subcompressed tapering at both ends ; style 

 slender much elongated, exserted : apex stigmatose capitate 2-lobed ; 

 valves nearly flat 1 -ribbed; septum membranous. Seeds go, 1 -seriate 

 compressed immarginate, funicles filiform. — A tall branching glab- 

 rous herb; leaves imparipinnatisect; leaflets unequal at base, falsely- 

 pedicellate unequally toothed ; flowers ' long-pedicellate, in bracteate 

 racemes; bracts leafy 2 {Venezuela, New Granada*). 



25. Smelowskia C. A. Mey. 4 — Flowers nearly of Erysimum ; 

 sepals short lax, equal at base. Siliqua rather short, tapering at 

 both ends, either laterally compressed or sub-4-gonous ; style short ; 

 apex minutely capitate stigmatiferous ; replum filiform included. 

 Septum membranous ; valves concave submembranous. Seeds few ; 

 1 -seriate immarginate; funicles free. — Perennial herbs, subca?spitose, 

 hoary tomentose ; leaves pinnati- or 2-pinnatisect ; flowers 5 racemose 

 ebracteate 6 (Siberia, Rocky Mountains 1 ). 



26. Zerdana Boiss. 9 — Sepals erect elongated, subequal at base. 

 Petals long-unguiculate. Stamens 6, 4-dynamous; the larger ones con- 

 nate in pairs half way up. Siliqua linear rather compressed sublinear 

 subtorulose ; valves subcarinate veined ; septum membranous, sub-2- 

 costate ; style subulate ; apex stigmatose, 2-lobed. Seeds go, 1 -seriate 

 oblong ; funicles filiform free. — A perennial csespitose herb, hoary 

 all over with glandular hairs ; rhizome elongated, double or multiple ; 

 leaves all radical, rosulate subspathulate-obtuse ; flowers 9 crowded at

1 Purple, large nodding. 



2 A genus very near Cardamine.

5 White or yellow, usually small. 



6 " An anomalous genus, which, perhaps, needs 

 breaking up, and is intermediate between Sisym- 

 brium, Futrema, Draba, and Capsella, by S. 

 calycina and others ; it also approaches Parrya 

 by P. Frmani {Draba parryoides Eeh.). In S. 



calycina, the siliqua is very variable, sometimes 4- 

 gonous, sometimes laterally compressed, short 

 or elongated." (B. H., loc. cit.) — According to 

 Fotjen. (in Bull. Soc. Pot. de Fr., x. 7),. B. 

 arthrocarpa Wedd. approaches Smelowskia in 

 flower and fruit.
