LXXIV.— SURIANEiE. 



In our Prodromns Mr. Arnoft viewing the gRnus Surlana as the type of an order, esta- 

 blished this one on it. Two years aFler, Dr. Lindley taking a similar view, published it under 

 the n^me of Surianaceee hut without the slightest notice or reference to the previously pnbli^ih- 

 ed name of Mr. Arnott. Why this omission ? 



This order established on a single species is thus characterized by Mr. Arnott. 



** Calyx .5-partite, persistent, aestivation twisted, imbricative. Petals 5, allernate 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 p* fals : 

 filaments persistent, distinct, subulate from a broad base, hairy below: anthers 2 celled, l)urst- 

 ing longiludinally. 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, I cell* 

 ed, 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 extremiry from the hilum. 

 Fruit of 5 coriaceous pyriform indehiscenl carpels. Seeds solitary, uncinate, aftHched to the 

 base of the carpels. Albumen none. Embryo of the same shape as the seed ; radicle as lung 

 as the cotyledons, at the opposite end from the hilum: cotyledons oblong, fleshy, incumbent. 

 Sea-side shru!>s. Leaves simple, cblong-spalhulafe, thickish, pubescent, crowded at the apices 

 of the branches, exstipulate. Flowers yellow, bracteated, soraewiiat ternjinal." 



Affivitiks. Before offering an opinion of my own I shall first quote the remarks of both 

 authors on this point. 



** We scarcely know where to arrani:^e the only genus of which this order i*? composed. 



Some refer it to Rosaceae ; Kualh proposes to place it near the Gera/iiaceae : we think it has
