Mr. J. Miers on the genus Lycium. 339 



hairs being always articulated, often short, and sometimes only 

 visible under the lens : they are also remarkable for ihe peculiar 

 glandular long adnate scale with fimbriated or barbated margins 

 attached to the lower portion of the stamens, and which by the 

 geniculation of the filaments at their origin, compot>e a fornix 

 that closes the tube of the corolla : they might almost form a 

 distinct section or subgenus {Celidophora) . The angles of the 

 branchlets generally exhibit raised reddish-coloured ribs which 

 spring from each side of the bony cupular or bracket-shaped 

 node seen at the origin of each branch or leaf. In this species 

 the leaves are often small, in some cases almost linear, in others 

 ovate, varying from 4 to 8 lines in length, and 1 to 3 lines in 

 breadth : the petiole is almost obsolete : the peduncle is 3 lines, 

 the calyx 2 lines long, which offers the peculiarity of being 

 thickly pubescent within as well as outside ; the pointed reflected 

 teeth are a line in length : the tube of the corolla is 2 lines 

 long, the segments of the border 3 lines ; the stamens are 2^ 

 lines in length : the scarlet berry is nearly 3| lines long and 

 2^ lines broad, and contains numerous small flattened reniform 

 seeds, in which the slender terete embryo makes a gyration and a 

 half, in a spiral form ; the radicle, nearly equal in length to the 

 cotyledons, points to the basal angle of the seed, avoiding the 

 lateral hilum. This shrub is very common along the coast of 

 Chile, where it is called Piquillin : it is no. 367 of Cuming^s col- 

 lection. I have not seen L. gracile of Meyen from the neigh- 

 bourhood of Coquimbo, referred to this species by M. Dunal, 

 which from the description appears to me to accord better with 

 L. salsum, R. & P.
