- Landolphia. | LXXXIV. APOCYNACE# (STAPF). 31 
sessile in few- or many-flowered corymbs at the ends of the branches 
(sometimes overtopped by barren sboots and then occasionally pseudo- 
axillary), or gathered in more or less elongate panicles at the ends of 
their distant branches which are (like the rhachis) sensitive, and act as 
hooks or tendrils. 
About 40 species, in tropical Africa, extratropical South-east Africa, and the 
Mascarene Islands. 
The plant described by Aublet as Pacouria is very probably a species of Lan- 
dolphia, § Ancylobotrys. It was found in French Guiana by Aublet, but has never 
been collected again, and is perhaps not indigenous there. The seeds of several 
species have been described as being covered with a dense coat of hairs. Lecomte 
has pointed out in Journ. de Bot. 1901, 86-88, that this appearance is due to the 
presence of a great number of laticiferous cells in the pericarp, the inner parts of 
which go to form the pulp. This closely envelops the seeds, and, as the orientation 
of the laticiferous cells is more or less at right angles to the surface of the seed and 
their refractive power differs from the rest, produces the impression of the presence 
of a coat of hairs.
