These isolated Cape genera form the most remarkable feature in 
the distribution of F'umariaceae, suggesting independent origin. 
The three genera forming the distinct and most primitive group 
Hypecoideae have each a separate distribution (see map, p. 101). 
Hypecoum extends from South-West Europe to Turkestan and the 
North-West frontier of India. Chiazospermum occupies a more 
north-easterly area, from Soongaria to North-East China; whilst 
Pteridophyllum is endemic to Central Japan. 
Dactylicapnos, which is here restored to generic rank, and 
Dicentra also occupy separate areas, the former from North- 
_ West Himalaya to Yunnan, the latter from Szechuan eastwards 
through Central China to the Eastern United States (see 
map, p. 105) 
Other genera of very restricted distribution are the four that 
occur at the Cape of Good Hope, Phacocapnos, Cysticapnos, T'ri- 
gonocapnos, and Discocapnos. Sarcocapnos (see map, p. 105) and 
Rupicapnos are confined to the Western Mediterranean, in Spain 
and North-West Africa, while Ceratocapnos, a genus of two very 
closely allied species, has one in North-West Africa, the other in 
the Holy Land. Adlumia has a wide range in the Eastern cage 
States, and Professor Komarov,* a few years ago, ma 
interesting phytographical announcement in _ recording this 
interesting plant from Corea. 
Corydalis is the most widely distributed genus of the family 
(see map, p. 109), occurring almost throughout the temperate 
zone of the Northern Hemisphere, but absent from Mediterranean 
North Africa, entering the tropic only in the mountains around 
Lake Victoria in Tropical East Africa, where two species have 
been discovered during the last few years, one, as yet unnamed, 
by Mr. Snowden, at 9,000-10,000 feet on Mt. Elgon, the other 
Corydalis Mildbraedit, Fedde, by Dr. J. Mildbraed in the 
mountains near Lake Kivu at an elevation of 7,700 feet. There 
is no true Corydalis in South Africa. 
Fumaria is also widely spread in the Northern Hemisphere, but 
is absent from North America except as a weed of cultivation.
