climbing lierbs. When they are perennial the subterranean part is 

 often a tuberous rhizome of variable form (157, 158), the evolution 

 of which presents numerous specific peculiarities. 1 The leaves are 

 alternate or subopposite, multisect exstipulate. The flowers form 

 terminal or leaf-opposed, simple or more 

 rarely ramified racemes. Corydalis inha- 

 bits Europe, Temperate Asia, North and 

 South Africa, and Temperate America. 



Sarcocapnos" has altogether the flower of 

 Corydalis; but the number of ovules on 

 each of the two placentas is small 3 or 

 often reduced to one only. The fruit is a 

 little, flattened, one- or two-seeded, inde- 

 hiscent achene. Three or four species 4 of 

 this genus are known, low lierbs, from the 

 Mediterranean, Spain, and North-western 

 Africa. Their leaves are dissected as in 

 Corydalis, with usually larger fleshier segments, 

 terminal paucifloral racemes. 



The Fumitories 5 (figs. 142, 159-165) offer a reduced type of Cory- 

 dalis and Sarcocapnos. They have the same flower in perianth 6 and 

 androceum, 7 and the indehiscent fruit of Sarcocapnos. But the ovary
