Prain.—A Review of the Genera 
a second species, local and endemic, near the southern border of Lower 
Guinea, in which area there is another endemic species. The section 
Psendathroandra has only two species, one of them endemic in Lower 
Guinea, the other in the 5 Zanzibaria ’ sub-region of East Africa. 
The section Hemierythrococca is confined to West Africa ; its three 
species are all endemic in Upper Guinea. The section Chloropatarie has 
eleven species in West Africa ; three of these are endemic in Upper and 
three in Lower Guinea. There is only one species common to both the 
Guineas, and this, which extends as far as East Central Africa, may be only 
an overflow from West Central Africa. Another species extends equally 
far to the East from Upper Guinea only ; one more from Upper Guinea 
and two others from Lower Guinea extend into West Central Africa. Of 
the six species of Chloropatane , one of them with a very distinct variety, 
which occur in West Central Africa, one, and the variety in question, are 
endemic; the remaining five are distributed, two to Lower Guinea only, 
one to Upper Guinea only, the other two to East Central Africa on the one 
hand, to West Africa on the other. In East Central Africa there are but 
three species of Chloropatane , and only one of these, so far as is known, is 
endemic. 
The distribution of the genus Micrococca is interesting, but presents 
no feature of difficulty. The only annual species, M. Mercnrialis , is a wide¬ 
spread tropical weed in the Eastern Hemisphere. In Africa it is common 
in cultivated ground in West Africa, both in Upper and in Lower Guinea ; 
it occurs both in West Central and in East Central Africa; it has been 
reported in East Africa, both from the Mozambique and the Zanzibaria 
subdivisions. It appears to be common also in North-East Africa, and 
extends thence to Southern Arabia. It has been met with in Madagascar. 
In Asia it is widely spread in Western, Northern, and Southern India, 
extends thence to Burma and the Malay Peninsula, and is common in 
Ceylon. The shrubby species have much more restricted ranges. One 
species, M. capensis , is confined to the eastern, or Natal, subdivision of 
South-East Africa, but is widely spread there from Pondoland to Delagoa 
Bay. Two species, M. Volkensii and M. Holstii , seem confined to the 
Zanzibaria subdivision of East Africa. One species, M. Hnmblotiana , is 
endemic in the Comoro Group; two, M. Wightii, with its distinct variety 
hirsuta , and M. Beddomei , are endemic in the Malabaria subdivision of 
India; the last species, M. oligandra , is endemic in Ceylon. 
The subjoined tables show the details of this distribution more com¬ 
pactly.
