86 CONTRIBUTION TO THE FLORA OF GAZALAND. 
Both Schumann (Engl. Bot. Jahrb. xxiii. 453) and De Wildeman deseribe 
and the latter (Pl. Nov. Hort. Then. i. t. 3) figures the ovule as solitary. 
On opening a cell of the ovary is seen а biscuit-shaped body—apparently а 
single ovule—hanging from the top of the cell. The width of this body in 
relation to its length, however, made me suspect its homogeneity ; accord- 
ingly it was examined under а low power of the compound microscope, when, 
as shown in РІ. 4. fig. 5, a couple of sharp points were seen projecting from 
either angle at the upper end. Sectioning showed each of these points to be 
the free portion of an ovule, the rest lying buried in the placentary tissue 
just as, for instance, is the case with the ovule of Myrsineæ. Fig. 6 represents 
semidiagrammatically the placenta with its two ovules; in this the integu- 
ment and the pyriform nucellus are well shown. There being only dried 
material to hand, no further details concerning these ovules are discoverable. 
One would much like to know how this singular body behaves in matura- 
tion ; possibly the second ovule at length aborts, and the food-stuff accumu- 
lated in its tissues and in that of the placenta serves to nourish the survivor. 
The result of this discovery is that //einsenia must be removed from the 
Alberteze, where Schumann placed it, to the Gardenie:, next to Итродопа. 
[The genus is also represented in Uganda, whence Mr. E. Brown has 
recently sent specimens to the British Museum of the following :—
