82 INTRODUCTION. 
The following summary of the foregoing facts affords good evidence 
of the richness of the Cape Peninsula in Orchids, and shows that 
it is only surpassed, if indeed it be surpassed, by some portions of 
Australia :—

V.—Disrrisution oF GENERA AND SPECIES. 
Of the ten genera represented on the Peninsula, four, viz., Bartho- 
lina, Corycium, Pterygodium, and Ceratandra, are exclusively confined 
to South Africa, Holothrix, Disa, Satyrium, and Disperis attain their 
maximum in South Africa, but have outliers in other parts of Africa, 
and the Mascarene Islands,—besides one species of each of the two 
last-named in the Indian Peninsula. Lastly, Liparis and Eulophia 
are very widely distributed over almost the whole globe. 
The distribution of the species is, however, much more restricted. 
Out of the 102 recorded on the Peninsula, only one as yet has been 
even said to be found beyond Southern Africa, viz., Liparis Capensis, 
which was thought by Dr. Hooker to have been discovered by Mann 
on the Cameroons Mountain,* where some other typical Cape plants 
have also been detected. Of the remainder— 
1 extends northward into Namaqualand (Karroo Region). 
52 extend eastward and northward within the Western Province 
(South-western Region). 
15 extend eastward through the last-named districts into the Sub- 
Tropical Region. 
33 have not yet been recorded beyond the limits of the Cape 
Peninsula. 
The last number will, however, doubtless be reduced as botanical 
exploration, hitherto very incomplete, is further extended. 
* The locality given is ‘‘ Cameroons Mountain, alt. 6.00—7000 ft. (Frt. Dec.)— 
A small species, in fruit only, but clearly the same as L. Capensis.”—Dr. J. D. 
Hooker, in ‘ Journal of the Linnean Society,’ vol. vii. (1864), p. 218.—I have seen 
Mann’s specimens, which certainly greatly resemble those of L. Capensis, but 
cannot regard the identification as sufficiently certain in the absence of flowers.
