104 NATURAL HISTORY OF PLANTS. 
The leaves are pari- or imparipinnate, with sometimes three leaflets, 
but usually with more, and possess caducous lateral stipules. Their 
flowers form simple or ramified axillary or terminal racemes, which 
are often reflexed. 
The flowers of Berlinia,' like Vouapa, are at first completely en- 
veloped by two coriaceous bracts; but the androceum consists of 
two quinary rows of fertile stamens as in Schotia, Baikiea, &c. The 
calyx consists of five imbricate sepals like those of Vowapa, and the 
corolla has but one large petal, the vexillary one, the other four being 
reduced to short scales. The multiovulate ovary is inserted on the 
posterior edge of the receptacle; the fruit is unknown. Halfa dozen 
species of Berlinia are known, fine unarmed trees from tropical 
Africa.? The alternate paripinnate leaves have stipules of variable 
size, and their lovely scented white flowers form simple or ramified 
racemes. 
The receptacle of Daniella’ forms a thick-walled cornet, on whose 
rim are inserted four imbricate sepals and a vexillary petal super- 
posed to the posterior sepal.*| The androceum consists of ten free or 
nearly free stamens, all fertile, in two whorls. The gynzceum is 
inserted by a slender foot not far from the bottom of the receptacle ; 
its ovary contains numerous descending ovules with their micropyles 
upwards and outwards, in two vertical rows. The fruit is a flattened 
elongated stipitate bivalve pod, often one-seeded. The embryo is 
exalbuminous, and the funicle dilates near the seed into a fleshy aril. 
At maturity the endocarp separates elastically from the mesocarp. 
The only known species’ of this genus is a handsome unarmed re- 
sinous tree from the west of tropical Africa. Its paripinnate leaves 
have unsymmetrical leaflets and caducous leafy stipules. Its nu- 
merous flowers form much-ramified compound racemes towards the 
ends of the branches.

4 This petal ‘‘is very variable in size and form, 
and often appears quite solitary when adult. But 
an examination of the young flower-bud reveals 
also two lateral petals besides two smaller (an- 
terior) ones, which usually disappear in the adult 
flowers. The lateral petals may have their de- 
velopment early arrested, or present all kinds of 
variations of form and consistency in the adult 
flowers.”
