wards. The stigma is furnished below with a disc, round 
which the anther-cells are fastened. The 2-celled ovary 
| divides, when ripe, into 
two long slender follicles, 
thus liberating a number 
of seeds, each furnished 
with a tuft of hairs at the 
hilum.

Parsonsia (mag.). 
Compare here also Periwinkle (Vinca), and note its remarkable 
stigma, shaped like an hour-glass. 
Of Gentians (Gentiana), the garden species are all European, and 
are blue-coloured. The New Zealand species are white, and some are 
very handsome; they flower in February and March. 
Nemophila, Phlox, Gilia, Cobea, &c., are commonly cultivated in 
gardens. 
Of Convolvulus and Ipomea, both wild and cultivated species are 
common. 
Poroporo, or, as it is commonly pronounced, Bullibulli (Solanwm 
aviculare), Potato (S. tuberosum), Petunia, Tobacco (Nicotiana), Tomato 
(Lycopersicum), &c., all with regular flowers, a 2-celled ovary, and seeds 
having a curved embryo in fleshy albumen, are more or less common.

The flowers are extremely irregular, and are arranged in 
bracteate racemes. ‘The 5-lobed inferior calyx is imbricate 
and persistent. The hypogynous corolla is also 5-lobed, and 
distinctly bilabiate,* or two-lipped. The upper lip is 2- 
and the lower 3-lobed, the opposite arrangement prevailing in 
the calyx. The lips are closely pressed together, and this 
form of bilabiate corolla is called personate.} The object 
of such a structure is evidently to prevent any but suitable 
insects from entering the flower ; and it appears to depend for 
its fertilisation solely upon different species of bees, which 
alone among flower-loving insects are strong enough to force
