hairs, which, on being rubbed off, leave an impression on 

 the surface ; glaucous, very pale beneath, with elevated, 

 sometimes pink-coloured, sublongitudinal, arched nerves, 

 having each a minute gland in their axils. Petioles very 

 short, furrowed. Head terminal, solitary, round, as large 

 as a moderate-sized cherry, thickly covered with flowers, 

 supported by a sulcated, club-shaped peduncle, which 

 widens at the upper end into a convex ligneous receptacle 

 for the insertion of the flowers. Involucre consisting of 

 four spreading, somewhat unequal, coriaceous, yellow, 

 obovate-cuneate, sometimes broad -ovate, veined, scabrous 

 leaves, an inch long, rounded at their ends, with a short, 

 slightly grooved point. Calyx cylindric, pubescent, with 

 four oblong, erect, obtuse segments. Corol twice as long 

 as the calyx, consisting of four spreading cuneate leaflets ; 

 their upper surface slightly keeled. Stamens equalling the 

 petals, subulate, recurved. Anthers ovate. Ovarium im- 

 mersed in the receptacle, oblong, 2-celled, with a pendulous 

 ovulum in each cell. Style thick, clavate, striated, shorter 

 than the stamens, surrounded at its base by a short, 

 cylindric, fleshy, crenulate nectary. Stigma truncate. 



" Obs. — This beautiful tree is very distinct from all the 

 other species. It approaches a little to C. florida and cana- 

 densis ; but is easily recognised by its copious, harsh, 

 adpressed hairs, its stature, which is that of a large shrub 

 or small tree, and the position of its leaves." 



We do not understand upon what principle this very 

 distinct genus has been combined with Cornus, from which 

 it differs essentially both in flower and fruit. Whether or 

 not Q. florida, which agrees with it in habit, is also a species 

 of Benthamia, our materials do not enable us to determine.
