dense white tissue and the placente themselves being divided 
into as many partitions as there are seeds, 
The ripe fruit is red except at the base, the septa of the 
placentz have now a veiny appearance, they separate with 
the seed, which nevertheless have the peculiar membranous 
spurious arillus, filled with juice in immediate contact with 
the seed. "The seeds have the usual appearance. 
The original cellular placentze are still traceable, but now 
consists of a mass of veins, ramified on the septa surrounding 
each seed, 
Such plants as Triceras, Actinostemma and Zanonia will 
throw light on the true nature of the fruit. - 
In the Kunkree Cucurbita, the obscuring circumstances 
take place very early, for even when the bud of the female 
flower is only 34 lines long; the Placentz fill the cavity of the 
fruit, and have assumed their triangular shape Pl. DCXVII.

the stigma. - 
At this period, the resemblance they bear to an inverted 
leaf is very striking, and the axis of the inner angle is occu- 
pied by a developing vascular axis. 
The stizmata at this period have acquired the form they 
are to bear, as wéllas the cohesion, they separate into 3 
lobes, (each of which is dilobed along the outer face). 
The separable lobes correspond with the placenta, that is, 
a line carried up along the inner angle of these will corres- 
pond with their axes, impinging on the sinus of their lobes. 
The perfect stigmata are remarkable enough, a transverse 
‘section of each lobe shews that it represents a leaf rolled 
outward, with its: margins curved, and placed in oppost- 
tion. (See the lower figure.) 
The. stigmatie surface occupies the whole innerface of 
the lobe (as respects the axis) and also the whole of the ap- 
parent outer surface itself, extending to the margins. 
Stigmatic surface, and what is remarkable, presents hairs 
The space formed by the incurvation is not occupied ee
