on the authority of an authentic specimen of Berlandier's, No. 2310, which is certainly the same 
as ours. 1618 a shrub 3 or 4 feet high, often quite unarmed, and usually the prickles are sparse 
and extremely short. Flowers yellow, turning to a deep brown. The fruit is about the size of 
a peppercorn and is juicy when ripe. It may be only a variety of L. Camara.

The ripe nutlets are the same in both. We know of no plants which, in the wild state, are 
more prone to hybridize than the North American species of this genus. Dr. Engelmann has 
enumerated (in Silliman's Journal, vol. ?,) many intermediate forms between V. ofticinalis, V. 
hastata, V. urticefolia, and V. strieta, which he found in the vicinity of St. Louis, Missouri.
