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:--
