364 FLORA NIGRITIANA. 
The close affinity, so well pointed out by Brown between 
this Order and Passifloree, has been objected to by Lindley, 
(Veg. Kingd. p. 742), on account of their “ inferior ovary, to say 
nothing of their want of stipules and glands on the leaves, of 
the presence of glands at the base of the floral envelopes, and 
of their erect and very different habit ;” but besides Dissomeria 
and the Madagascar plant alluded to by Brown, in which the 
ovary is truly free, the other genera offer, as observed by 
Brown, very different degrees of adherence, and in almost all 
cases the summit, which is the only placentiferous portion, is 
free; stipules, though very deciduous, may be found on the 
young branches of most, if not all the species ; glands exist in 
the crenatures of the leaves of several species, and are not universal 
in Passifloree ; and the habit is surely much nearer to that of 
Smeathmannia and the allied genera than to any Cactee or 
Loasee. The glands of the flower, combined with the insertion 
of the stamens, remain the only essential characters which pre- 
vent the actual union of Homalinee with Passifloree.
