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 on a single species is thus characterized by Mr. Arnott.

"Calyx 5-parlite, 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, burst- ing 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."

Affinities. Before offering an opinion of my own I shall first quote the remarks of both authors on this point.

"We scarcely know where to 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
