LXXIV.—SURIANEÆ.
In our Prodromus Mr. Arnott viewing the genus Suriana as the type of an order, established
this one on it. Two years after, Dr. Lindley taking a similar view, published it under
the name of Surianaceae but without the slightest notice or reference to the previously published
name of Mr. Arnott. Why this omission ?
This order established oh a single species is thus characterized by Mr. Arnott.
“ Calyx 5-partite, persistent, aestivation twisted, imbricative. Petals 5, alternate with the
sepals, distinct, inserted into the bottom of the calyx. Stamens 5, alternate with the petals,
sometimes with 5 alternating ones that are occasionally abortive, all inserted with the petals :
filaments persistent, distinct, subulate from a broad base, hairy below: anthers 2 celled, bursting
longitudinally. Torus fleshy, filling up the bottom of the calyx, supporting the ovaries on
its middle and the petals and stamens on its margin. Ovaries 5, opposite to the petals, 1-celled,
distinct, each with a long style arising from the inner angle near the base. Ovules in
pairs, collateral, erect, straight, with the foramen at the opposite extremity from the hilum.
Fruit of 5 coriaceous pyriform indehiscent carpels. Seeds solitary, uncinate, attached to the
base of the carpels. Albumen none. Embryo of the same shape as the seed ; radicle as long
as the cotyledons, at the opposite end from the hilum: cotyledons oblong, fleshy, incumbent.
Sea-side shrubs. Leaves simple, oblong-spathulate, thickish, pubescent, crowded at the apices
of the branches, exstipulate. Flowers yellow, bracteated, somewhat terminal.”
A ffin itie s. Before offering an opinion of my own I shall first quote the remarks of both
authors on this point.
i( We scarcely know whereto arrange the only genus of which this order is composed.
Some refer it to Rosaceae ; Kunth proposes to place it near the Geraniaceae: we think it has
