2-lobed above. Ovarium bilocular, obsoletely 4-sided, surrounded
at the base by a cup-shaped slightly crenulate disk.
Ovula numerous, attached to two fleshy placentae.
A native of sandy plains on the banks of the Parana,
where it was discovered by Mr. Tweedie, and from seeds
transmitted by him to Mr. Neill, the plant was raised in
the garden at Canonmills in 1832. The drawing was taken
by our friend Mr. James M’Nab in the month of August
last year. In habit it comes very near to gracilis andjilicaulis,
but is essentially distinguished from these, as well as from
every other species of this section, by its broad orbicular,
not compressed stigma, which is entirely that of the section
Petunia. The form of the corolla is but a character of
secondary importance among the Solaneee, as is evinced by
the variety which occurs in Solanum, Nicotiana, and in
others of the larger genera.
We have remarked in this species, as well as 'wijilicaulis
and gracilis, that one of the lobes of the anthers is occasionally
abortive.
The plant thrives best in a mixture of peat and sand,
and roots freely at every joint, if the branches are allowed
to lie on the surface of the earth.
For the meaning of the generic name, see fol. 172.
