184 Mr. J. Miers on the genus Lycium. 



twisted and interlaced branches and small leaves, and has evi- 

 dently grown in an exposed and arid situation ; while the latter 

 has long, slender, virgate branches, and abundant foliage of much 

 larger leaves, and was apparently produced in a damp and sheltered 

 places, favourable to its more luxuriant growth. Dr. Stocks' 

 specimens present more the aspect of L. Barbarum, but are 

 distinguished by their much shorter peduncles, more fleshy 

 leaves, and a generally more tartareous appearance ; the very 

 flexuose divaricating branches are covered with a splitting bark 

 of a cretaceous hue, with fascicles of few leaves (three to six) 

 proceeding out of the knotty base of the axillary spines : the 

 leaves are linear, obtuse at the summit, tapering below into a 

 short petiole ; they are remarkably thick and fleshy, of a pale 

 glaucous hue, 4 to 9 lines long and i line broad : one to five 

 flowers grow out of each fascicle ; the peduncle is 2 lines long ; 

 the pale glaucous, tubular calyx, often unequally cleft, is \\ line 

 long : the tube of the corolla, greatly contracted in its lower 

 moiety and funnel-shaped above, is 3 lines long, the oblong 

 segments of its border being 2 lines in length ; it is quite smooth, 

 excepting a little appearance of pubescence about the insertion of 

 the stamens, which are unequal in length, the filaments being 

 quite smooth, one not extending beyond the mouth of the tube, 

 two of the length of the segments, and the other intermediate ; 

 the style is the length of the longer stamens. It will be seen 

 how little this structure differs from L. Barbarum, and it might 

 be almost considered as a mere variety of that species, from 

 which it is easily distinguishable by the characters above enu- 

 merated*.

A plant completely with the habit of L. Barbarum, but dif- 

 fering in the structure of its flowers. The steins are smooth, 

 very pale, flexuose, with spinose spreading branchlets ; the axils 

 are nodose ; the leaves, two to four in each axillary fascicle, 8 to 

 15 lines long and 1 to 2^ lines broad, are quite smooth and 

 fleshy : several flowers spring out of each fascicle ; the peduncles 

 are 2-2| lines long, the calyx 1 line, the tube of the corolla 

 3 lines, the segments of the border 2 lines ; the filaments are
