290 NATURAL HISTORY OF PLANTS. 
the corolla in the bud to issue above it elongated, anthers, and 
an ovary with five multiovulate placentas, surmounted by an equal 
number of style divisions, with a large stigmatiferous head; 
Bergsmia, which, with the 
Kiggelaria africana. perianth of Pangium, has much 
smaller flowers in racemes, 
and nearly as many alter- 
nate stamens as petals. In the 
female flowers they are reduced 
j to four or five sterile tongues ; 
Re sn meanest in the male, their filaments are 
Male flower (3). Female flower (2). joined below into a tube round 
the rudiment of a gynæceum, 
and their radiating anthers, at first introrse, turn their lines of dehis- 
cence decidedly upwards. In Zrichadenia the calyx is unequally torn 
or detached circularly at the base. The stamens are narrow and elon- 
gated, like those of Gynocardia ; but the cells are marginal, and the 
androceum isostemonous. The placentas are generally uniovulate. 
Hydnocarpus has from five to eight stamens. In the female flower they 
are often fertile, that is to say, provided with a basifixed anther, often 
reniform, with marginal cells. The placentas are often pauciovulate, 
and the ovules ascendent, with the micropyle directed downwards 
and inwards. ‘The calyx, instead of being gamosepalous and val- 
vate, is composed of leaves very distinctly imbricated. it is the 
same in Rawsonia, closely connecting Pangiee to Bixee by means 
of Oncoba, the polygamous flowers of which have from four to five 
sepals, passing gradually to a like number of petals, lined within 
by a plate almost petaloid, or covered with down, and‘very numerous 
* stamens with anthers more or less sagittate at the base, and in- 
serted upon a receptacle more or less dilated. The ovary contains 
from two to five multiovulate placentas, and is surmounted by a 
style with lobes more or less developed, erect or finally patulous 
and radiating. Lastly, Avggelaria (figs. 330, 331) has a valvate 
or scarcely imbricated calyx, anthers only dehiscing for a short 
distance near the apex, and a fruit which opens with difficulty, or 
incompletely into a variable number of valves.
