FLORA OF TIBET OR HIGH ASIA, 253 
Genera. 
Out of the 119 genera less than a dozen are peculiar to the 
region ; that is, to Tibet and the immediately contiguous countries, 
and it is exceedingly doubtful whether any genus is endemic 
in, or confined to, Tibet. The few more or less local genera 
are :— 
Dilophia (Crucifere), a diminutive monotype ranging from 
Ladak in the south-west across Tibet to Kansuh in the north- 
east. 
Lhylacospermum (Caryophyllacee), a monotype widely spread 
in the Himalayas, Turkestan, Tibet, and Mongolia. A moss-like 
plant forming excessively dense cushions. 
Stracheya (Leguminose), an almost stemless monotypic herb 
having prickly pods, limited to the Himalayas and the extreme 
west of Tibet. 
Allardia (Composite), a genus of about half-a-dozen dwarf 
herbaceous species inhabiting the Himalayas, Tibet, and Chinese 
Turkestan. 
Cremanthodium (Composite), better treated as a section of 
Senecio, which consists of eight or ten almost stemless herbaceous 
species inhabiting the Himalayas and Tibet. 
Cyananthus (Campanulacee), a genus of about eight tufted 
herbaceous species inhabiting the Himalayas, Tibet, and Western 
China. 
Microula (Boraginacex), a genus of two or three dwarf her- 
baceous species inhabiting the Himalayas, Tibet, Kansui, anil 
Western China. 
Oreosolen (Scrophulariacex), two stemless herbaceous species, 
one in the Himalayas and the other in Tibet. —— 
Gooringia, Williams, is a genus founded on drenaria Little- 
dalei, Hemsl., which, if accepted, would constitute, so far as our 
present knowledge goes, an endemic genus ; but we prefer retain- 
ing it in drenaria, at least until this group has been more 
thoroughly investigated. _ ; 
In contrast to this poverty of local genera is the numerically 
large representation of families and widely dispersed genera, as 
the following list shows :—
