138 Mr. J. Miers on the genus Lycium. 



way from Mendoza to San Luiz. It varies in having the leaves 

 more or less crowded, more or less attenuated; they are from 3 

 to 6 lines long, \ line broad ; the peduncle is 1| or 2 lines long ; 

 the calycine tube is cylindrical, f line long, with narrow, linear, 

 acute segments 1\ line long : the tube of the corolla is 4 or 5 

 lines long, the segments of its border are f line long, the larger 

 stamens are 2 lines in length : the oval berry is 3 lines long*. 



32. Lycium Berlandieri, Dun. in DC. Prodr. xiii. 520. — Mexico, 

 prope Laredo (Berlandier). 



33. Lycium senticosum (n. sp.) ; — intricato-ramosum, ramis tor- 

 tuosis, angulatis, griseo-helvolis, fere aphyllis, ramulis patenti- 

 bus, apice spinosis, foliis e nodis cottoneis prominentibus 

 paucis (2-3) fasciculatis, parvulis, lineari-spathulatis, obtusis, 

 glabris ; floribus solitariis, folio duplo longioribus, peduncu- 

 latis, glabris ; calyce parvo, poculiformi, insequaliter 4-dentato, 

 dentibus acutis, tubo duplo brevioribus ; corollae pallide flavse 

 tubo imo coarctato, infra e medium repente ac late campanu- 

 lato, limbi laciniis 4, curtissimis, tubo 4to brevioribus, rotun- 

 dato-deltoideis, reflexis; staminibus 4 exsertis, 2 paullo lon- 

 gioribus, filamentis in coarctationem tubi insertis, hinc geni- 

 culars et longiuscule hirsutis, superne capillaribus et glabris, 

 stylo staminibus longiore. — Mexico, ad Monterey. — v. s. in 

 herb. Hook. (Berlandier, Jan. 1828). 



This is evidently very near L. Berlandieri, and may possibly 

 be only a tetramerous variety of it. It appears to be more barren 

 of leaves, which are smaller and fewer in each fascicle : the leaves 

 are 2|- 3 lines long, \ line broad ; the pedicels are 2-2^ lines 

 long, the calyx is nearly a line long, the tube of the corolla 

 2 lines, the segment of the border If line in length; the con- 

 tracted portion of the tube is narrow, and a little longer than 

 the calyx, when it is suddenly enlarged into a bell-shaped form ; 

 the style is the length of the longer stamens, and the lower part 

 of the ovarium is encircled by the cupular remains of the corolla, 

 which here breaks away by a circumscissile line : this same pro- 

 cess is described as existing in L. Berlandieri ; but it partakes in 

 no degree of the nature of a disk, as stated by M. Dunalf- 



34. Lycium barbinodum (n. sp.); — intricato-ramosum, subinerme, 

 valde foliosum, ramis angulatis summe nodosis, cortice fusco, 

 nodis majusculis, prominentibus, subglobosis, albido-cottoneis; 

 foliis plurimis (6-8) fasciculatis, internodiis duplo longioribus,
