quantities. Our drawing was made in August 1828, in 
the Horticultural Society's Garden, where it had been 
raised from Mr. Douglas's seeds. 
. This genus is highly interesting in several points of 
view. 
In the first place, it exhibits a second instance of uni- 
locular fruit with parietal placente, in an order with multi- 
locular fruit and axile placenta ; but the fruit is constructed 
upon a very different plan from that of Lysipomia, to which 
it is in this point of view to be compared : while Lysipomia 
exhibits a placenta apparently parietal, in consequence .of 
the abortion of two cells of a trilocular ovarium, Clintonia 
has its placente absolutely parietal, without any abortion 
of the same nature. 
In the second place, it is an instance, and a very 
uncommon one, of the abortion of one of the placentas of 
'an ovarium made up of three carpella, having a triangular 
figure, and finally bursting into three valves. 
Thirdly, this deviation from' the normal structure of 
the order is unaccompanied by any corresponding irregu- 
larity in the other parts of the fructification. 
A procumbent annual, but little branched, and destitute 
of hairs. Stem terete, angular. Leaves sessile, ovate, with 
three principal veins. Flowers solitary, axillary. | Ovarium 
sessile, tapering to a point, four or five times as long as the 
leaves, triangular, twisted. Corolla blue, the lower lip 
with a clear white spot. Anthers blue. Stigma conical, 
surrounded by a papillose beard. Capsule much longer 
than the leaves. Pollen oval, with a furrow in the middle. 
When the seed-vessels are quite ripe they split into 
three strap-shaped valves, which cohere by either ex- 
tremity. The seeds are minute, brown, smooth.
