CYRTANDREÆ (AUCT. C, B. CLARKE). 3 
$ 2. GEOGRAPHIC DISTRIBUTION. 
The Old-World Cyrtandreæ love heat and moisture; the great 
body of the tribe is situated in south-east Asia extending from India 
to-Japan and New Guinea; a single genus (Cyrtandra) having 
numerous species scattered through Polynesia to Tahiti and the 
Sandwich Isles. The Cyrtandreæ may be conceived as nearly conti- 
nuous over this area, abounding both in variety of forms and number 
of individuals. External to this area we find only a few small groups : 
viz. in Europe, one species (Ramondia) in the Pyrenees, and 3 spe- 
cies (Ramondia, Haberlea) in the Balkans; in South Africa, from 
the Cape to the Cameroons and Zanzibar (including Madagascar) 
22 species, of which 18 belong to one endemie genus (Streptocar- 
pus); in Australia 4 species and in New Zealand 1 species. Out of 
the 460 species described in the present Monograph, all except 
12 are confined between 30° N. L. and 30° S. L.; the extreme 
uorth points reached by the Tribe being the Pyrenees, the Balkan, 
North China and Japan; the extreme south, the Cape, the Aus- 
tralian Blue Mountains, and the Northern Island of New Zealand. 
Of the whole 460 species, 350 are concentrated in India and 
Malaya; while, of the remaining 110, 73 are from the Polynesian 
Islands. 
The Distribution of the Genera is set out in the annexed Table 
where Africa includes Madagascar ; North India includes the Hima- 
laya, Assam, Khasia and Chittagong; the Malay Peninsula extends 
from Pegu to Singapore including Penang ; the Malay Islands reach 
from Sumatra to Papua; East Asia includes Japan, China and 
Cochin-China; Australia ineludes the small islands adjacent. 
The regions have been divided thus minutely in order to bring 
out the exceedingly localised distribution of the species and genera. 
Though the limits assigned to the regions are at so many points arbi- 
trary, it is seen by adding up the totals of species in the various 
regions that these never greatly exceed the total of the species in the
