NATURAL HISTORY OF PLANTS. 
dibuliform or hypocrateriform, with narrow tube and limb divided 
into five equal lobes.’ The androceum is formed of ten stamens 
superposed, five to the divisions of the calyx, and five placed lower, 
to the lobes of the corolla. They are all inserted towards the throat 
of the latter, and each formed of a two-celled, introrse anther dehis- 
cing by two longitudinal clefts, and of a filament which varies some- 
times in length,’ sometimes inasmuch as it is free or united to a 
Papaya Carica.

variable distance from the base with the neighbouring filaments.* 
A rudimentary gynæceum, with tapering apex, occupies the bottom 
of the flower. In the female flowers there is a calyx analogous to 
that of the male flowers, and a corolla with five free petals, valvate 
or contorted in the bud. The androceum is totally wanting, or more 
rarely it is formed of a variable number of hypogynous stamens, 
little developed but fertile however, like those of the male flowers.’ 
The gynæceum, here completely developed, is composed of a free 
unilocular ovary, surmounted by a style with five branches, more or

The corolla is generally large, white, yellowish, or 
greenish. In the true Papaya (Hupapaya) DE

as being constantly ‘ dextrorsum (e centro 3 The monadelphia is more or less pronounced
