the corolla in the hud to issue ahove 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 

 Kiggeiaria ajHacma. perianth of Pangi/nn, has much 



smaller flowers in racemes, 

 and nearly as many alter- 

 nate stamens as petals- In the 

 female flowers they are reduced 

 to four or five sterile tongues ; 

 in the male, their filaments are 



Male flower (f). Female flower (f). joined below into a tube l'OUlld 



the rudiment of a gynseceum, 

 and their radiating anthers, at first introrse, turn their lines of dehis- 

 cence decidedly upwards. In Trichadenia 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 Bawsonia, closely connecting Pangiece to Bixece 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, Kiggeiaria (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.
