ing the first section of the order Rosacee in Jussieu's 
Genera Plantarum; a treatise about to appear in the forth- 
coming volume of the Transactions of the Linnean Society. 
We have only seen a part of it; whence we have extracted 
the above generic and specific characters.

and one doubtful species, natives of California and the 
temperate regions of Asia, all hitherto ranking in the genus 
Craracus. The limits are technically defined by “ a five- 
toothed calyx: reflex petals: a semisuperior villous two-celled 
germen: two smooth styles: a two-celled seed-vessel en- 
closed in a fleshy calyx: and a cartilaginous seedcoat.” The 
congeners are all arborescent, with a simple coriaceous ever- 
green, sometimes serrate, sometimes entire-edged foliage, 
compound corymbose panicles, and a small smooth-rinded

greenhouse-plant; flowers about August, and is distin-
