 rying to elliptic, and lance-oblong, often with a short abrupt acumination, finely

 under surface usually very tomentosc (sometimes nearly smooth), pale, the upper 

 surface smooth, deep green, with numerous dark purple glands on the midrib; 

 petioles 1 line to 1 third of an inch long, pubescent. Flowers in terminal pedun- 

 culate cymose or compound corymbs; pedicels villose, with smoothish deciduous 

 bracts at base. Calyx villose ; segments erect, acute, minutely glandular on the

Ob8. The P. melanocarpa, Willd. (Aronia arbutifolia, Pers.) with the calyx and 

 leaves beneath smooth, and fruit nearly black, has been very properly, 1 think, 

 reduced to a variety of this. I have specimens from E. Marlborough, which appear 

 to belong to that variety,— but it is much more rare than the red-fruited one.
