 ma capitate, somewhat emarginate. Drupe depressed-globose, white, with a

Obs. This species is not very commi o ; but has been found in several place* 

 within the County, since my Catal gue was published. 1 am much inclined to the 

 opinion of Prof. Hooker, that this will prove to be only a variety of C. albu, -as 1 

 have found specimens extremely like it, with the inflorescence cytnose. The 

 C.etricta, Lam. may, also, be nothing more lhan a variety. 



* * Leaves alternate. 



4. C. alternifolia, L. Branches and loaves somewhat alter- 

 nate; leaves ovate, or oval, acute or acuminate, hoary beneath ; cymes 

 depressed, spreading; drupe globose, bluish black. Beck, Hot. p. 154.

Stem 10 to 16 feet high, with spreading irregularly alternate branches, which 

 are covered with a yellowish green bark, streaked with numerous oblong white 

 warts. Leaves somewhat alternate, often nearly opposite, about 3 inches long, 

 and one and a half to 2 inches wide, on petioles about an inch in Length, ovate, or 

 elliptic, more or less acuminate, smooth above, hoary and somewhat pilose be. 

 neath, margin and petiole slightly ciliate-pubesccnt ; nerves rather ferruginous. 

 Floirers in depressed spreading cymes. Calyx somewhat pubescent; segments 

 nearly obsolete. Corolla yellowish white \ petals lance-oblong. SHgma subcapi- 

 late, obtuse. Drupe globose, dark blue, or bluish black, when mature ; nut 2 or 

 3-celled. 

 Hob. Moist thickets ; fence-rows, &c. frequent. Fl. May-June. Fr. Aug. 



Obs. Four or five additional species are enumerated in the U. States,— of which, 

 however, one or two are not well established. The C canadensis ,-an interest- 

 Ing little herbaceous species, with an involucrc,-occurs in abundance on the IV 

 kono Mountain, in this State ; but seems to be very much confined to such regions.
