NATURAL HISTORY OF PLANTS. 



flowers 1 racemose, ebracteate, or lower ones bracteate (South Russia, 

 the East, Siberia:). 



30. Pachypodium Nutt. 3 — Sepals elongated, equal at base or 

 lateral slightly saccate. Petals much elongated-contracted. Stamens 

 6, 4-dynamous ; anthers elongated twisted. Siliqua raised on a short 

 thick gynobase, rather short or elongated torulose ; style short ; 

 stigmatose apex capitate or emarginate ; valves convex, with a pro- 

 minent rib ; septum hyaline, slightly thickened at middle or ribless. 

 Seeds oo, more rarely few, 1-seriate oblong ; embryo rather fleshy ; 

 cotyledons obliquely incumbent ; funicles free slender. — Annual 

 or 2-ennial robust glabrous herbs ; leaves entire laciniate or 

 pinnatifid ; flowers 4 in elongated racemes or dense coombs, ebrac- 

 teate 5 ( Calif orn ia 6 ) . 



31. Stanleya Nutt. 7 — Sepals equal at base, spreading. Petals 

 narrow elongated long-unguiculate. Anthers elongated, finally 

 twisted. Siliqua long-stipitate, 8 much elongated slender, 4-gonous- 

 subterete rather compressed ; style very short or nearly absent ; 

 stigmatose apex entire; valves carinate 1-ribbed; septum membran- 

 ous. Seeds oo, ] -seriate descending oblong subterete ; funicles slen- 

 der free. — Glabrous glaucous perennial herbs ; 9 leaves simple entire or 

 pinnatifid ; flowers 10 in elongated straight multifloral racemes, ebrac- 

 teate (California 11 ). 



32 ? "Warea Nutt. 12 — Flowers nearly of Stanleya ; sepals short. 

 Petals rather broad, narrowed at base but not unguiculate. Siliqua
