20 Mr. J. Miers on the genus Lycium. 



This is a mere fragmentary specimen, agreeing sufficiently 

 with AVilldenow's description, but whether it be identical with 

 the original, or it be the same as that described by M. Dunal, I 

 have no means of judging. The foregoing diagnosis is therefore 

 only founded upon Drege's plant above mentioned : it consists of 

 a branchlet 5 inches long, with spinous axils \ inch apart ; the 

 spines are slender, bare, 3 or 4 lines long, each springing out of 

 a crowded fascicle of leaves, which are spathulately linear, 3 to 5 

 lines in length and ^ line broad ; a single flower arises out of 

 each fascicle, the peduncle being 2 lines long ; the smooth calyx 

 is 1^ line long, with five short rather equal teeth ; the tube of 

 the corolla is 3 lines long, and the oblong segments of its border 

 1 line*.

With these plants I am wholly unacquainted, but from the 

 descriptions quoted, no specific difference is perceptible between 

 them, as was suggested by M. Dunal himself. 



22. Lycium pendulinum (n. sp.) ; — ramosum, ramulis gracilibus, 

 pendulinis, annotinis strumoso-nodosis, subnudis, apice spi- 

 nosis, junioribus foliosis, foliis e cupula ossea axillari fascicu- 

 latis, linearibus, acutis, in petiolum tenuem imo angustatis, 

 eveniis, glaberrirais ; flore e fasciculo solitario, pedunculo gra- 

 cili, calyce 4plo longiore, calyce tubuloso, breviter ac subse- 

 qualiter 5-dentato, corolla infundibuliformi, imo intra calycem 

 coarctata, et extus pilosa, superne glaberrima, limbi laciniis 

 oblongis, venosis, tubo 4plo longioribus, staminibus insequa- 

 libus, uno longiore exserto, 2 faucem attingentibus, 2 brevi- 

 oribus inclusis : filamentis supra coarctationem tubi insertis, 

 hinc nudis et geniculatis, mox fasciculo globoso pilorum mu- 

 nitis, superne glabris; stylo filiformi, exserto. — C.B. S. — v. s.

This plant accords more with L. tenue, Dun., than with L. 

 tenue, Willd. ; its branches are very slender and pendulous : the 

 leaves are 4 or 5 lines long, ^ line broad ; the peduncle is 3 lines 

 long ; the tubular calyx 2 lines, with five short erect teeth ; the 

 corolla is 3 lines long, and the oval segments of its border ^^ to ;[ 

 of its length t-
