FLORA NIGRITIANA. 383 
contains several African and one East Indian species. Amongst 
them, R. Bowieana differs from the others by the calycine 
limb divided to the base. 
: 2. Randia (Ceriscus). Lobes of the calyx not divided to the 
base of the limb, and often foliáceous. Corolla of a thick 
consistence, with a short thick tube, and broad, blunt, often 
undulate lobes. These species are all African or Asiatic, and 
include, amongst others, R. dumetorum and its allies, as well 
as Lachnosiphonium, Hochst., in my specimen of which at 
least the ovary has certainly two cells only. 
8. Randia (Genipantha). Calycine limb tubular or campanu- 
late, with short teeth. Tube of the corolla cylindrical, not 
twice as long as the calyx, lobes pointed.—African species, 
connecting Randia with Oxyanthus. 
4. Randia (Oxyceras). Calycine lobes long and narrow, usually 
divided to the base. Tube of the corolla slender and cy- 
lindrical, not much longer than the calycine lobes.—All 
American species. 
5. Randia (Euclinia). Calycine lobes usually short and not 
divided to the base. Tube of the corolla considerably longer 
than the calycine lobes, and slightly dilated under the limb.— 
The genuine species are all American, excepting perhaps one 
undescribed one from Senegambia, which comes very near 
to them, and the R. longistyla, differing rather more in 
the remarkable style, which may probably hereafter be consi- 
dered as the type of a sixth group. . 
Oxyanthus, with its very slender tubed corolla and small 
calyx, and Griffithia, with a very deciduous limb of the calyx are, 
again, in close connection with the above groups. eos
