78 ILLUSTRATIONS OF 
equal oblong segments of the length of 2 lines, with deep 
inflected estivation ; both the calyx and corolla are smooth 
nside, and are covered on the outside with dense stellate 
tomentum. The stamens are included, the filaments rise from 
about the middle of the tube, out of as many prominent 
longitudinal ridges, which are retrorsely pilose, they are 
quite smooth above; the anthers are deeply cordate, 2-lobed, 
fixed on the apex of the filament, the lobes being oval 
and slightly scabrid. The pollen grains are spherical 
3-grooved, with alternating convergent lines. The ovarium 
is ovate, very sericeous, surmounted on a distinct glabrous 
stipes, which is surrounded by a short tubular cup, being 
a persistent portion of the corolla, which here breaks off 
by a horizontal line as I have described in Alibrewia, a feature 
I find to be apparent in nearly all the species hitherto placed 
in the Cestrinee that I have examined. The style is columnar, 
erect, suleated, slightly but distinctly scabrid in its entire 
length, and is longer than the corolla; the stigma is bilabiate, 
the upper lip being erect and longer than the other, which is 
somewhat declined. The capsule is curved, cylindrical, 
4-grooved, about double the length of the persistent calyx, 
smooth, bursting by four nearly equal fissures that extend 
half way down. They usually contain two or four seeds 
in each cell, imbricate in two series; they are oblong, com- 
pressed, winged and keeled, much in the same manner 
as in Metternichia, only smaller and broader in proportion ; 
the cavity containing the embryo is about 2 lines long, $line 
broad, the inner membrane remains attached as a lining 
to the cavity, the albumen, which entirely fills the cell, 
is thin and fleshy, and encloses an embryo of the same 
cylindrical shape ; this is nearly straight, slightly sigmoid in 
one direction, and a little curved in the other, the cotyledons 
are not broader than the radicle, are semiterete and some- 
what compressed, and are about half the length of the 
inferior radicle.*
