[* This remarkable plant constitutes a new and very curious genus of
Sterculiads. It agrees with STERCULIA in the position of the radicle with
respect to the hilum, but it is, otherwise, a BRACHYCHITON, with which it
more especially corresponds in the singular condition of the seeds. These
are placed, six together, in the interior of long-stalked, ovate,
mucronate, smooth, deep brown follicles, of a tough papery texture, and
lined with a thin fur of stellate hairs. The seeds themselves are also
closely covered with starry hairs, which are so entangled that they hold
the seeds together firmly; these hairs, however, are absent from the
upper half of the seed, whose thin brittle vascular primine is shining,
smooth, and marked with a brown nipple, the remains of the foramen.
Within the primine lies the bony crustaceous secundine, which is quite
loose, and seems as if it were independent of the primine. Eventually the
end of the thin brittle primine breaks like an eggshell and the secundine
falls out. The seeds themselves, remaining attached to each other and to
the follicle, resemble six deep cells, or may be rather compared to half
a dozen brown eggshells, placed on the broad end, from which the young
have escaped through the point.

Sir Thomas Mitchell has named the genus after Sir Henry T. De la Beche,
as president of a Society which has greatly encouraged him in his
Australian researches; and in honour of a science which has occasionally
thrown some light on his dark and difficult path. It may be
scientifically described as follows:--
