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. 
Puorinia, as far as yet known, includes three certain 
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 _ 
fruit. 
_ Arbutifolia is from California, whence it was introduced. 
by Mr. Archibald Menzies in 1796. It forms a handsome 
greenhouse-plant; flowers about August, and is distin-
