190 Mr. J. Miers on the genus Lycium. 



petiolum tenuem spathulatis, utrinque viscoso-puberulis, pilis 

 crebris, brevissimis, crassiusculis, glanduliformibus; floribus 

 subsolitariis, breviter pedunculatis, calyce insequaliter 4- rarius 

 5-fido, segmentis acutis, subreflexis, utrinque glanduloso- 

 pubescentibus ; corollse tubo extus glandulis brevibus farinoso- 

 puberulis, calyce 2plo longiore, infundibuliforme, limbi laci- 

 niis 5, oblongis, margine ciliatis, tubo brevioribus : stami- 

 nibus 5 insequalibus, 3 longioribus laciniis aequilongis exsertis, 

 filaraentis tenuibus, medio tubi insert is, imo geniculars et 

 longe hirsutis, superne glabris : stylo exserto, cum ovario arti- 

 culato; ovario corolla? reliquo semi-vestito. — Chile. — v. s. in 

 herb. Lindley (Coquimbo) MacRae. 



This species differs little from L. floribundmn, Dun., but its 

 branches are more intricately spreading and spinose, the bark 

 is darker and more farinose, the leaves are smaller and more 

 oblong ; on the other hand, their axillary nodes are equally ap- 

 proximated, and there is no difference in the size or structure of 

 the flower. The leaves are \\ to 2 lines long, | line broad; the 

 barren spines are 2 to 3 lines, the gemmiferous 4 to 6 lines or 

 longer; the peduncle | line; the calyx 1^ line long, cleft nearly 

 halfway into five very acute teeth ; the tube of the corolla is 2 

 lines, and its segments 1 \ line long ; it is glabrous, except near 

 the point of insertion of the stamens : the filaments are pilose 

 at their base for a quarter of their length, three of them reach the 

 extremity of the segments, two are shorter ; the slender style is 

 the length of the longer stamens, and is articulated with the 

 ovarium*. 



53. Lycium tenuispinusum (n. sp.) ; — fruticosum, intricato-ramo- 



sum, ramulis helvolis, viscoso-puberulis, valde divaricatis, 



tenuiter et crebre spinosissimis : foliis minutis, fasciculatis, 



anguste linearibus, viscoso-puberulis ; floribus e fasciculis soli- 



tariis, calyce tubuloso, pilis articulatis crebre pubescente, ultra 



medium 5-fido, segmentis lanceolatis, subreflexis, pedunculo 



gracili sequilongo ; corolla tubulosa, tubo calyce sequante, parte 



infimo cylindrico, attenuato, pilosulo, superiori innato, glabro, 



limbi laciniis tubo brevioribus, oblongis, staminibus exsertis, 



filamentis supra medium insertis, hinc geniculars et hirsutis, 



2 ultra faucem prolatis, 3 fere ad apicem laciniarum extensis.

This species, which I found near Mendoza, in the desert tract 



called La Travesia, in many points resembles L. floribundmn and 



rachidocladum, but is widely distinct. It is remarkable for its 



almost denuded, slender, spreading brauchlets, armed with short, 



closely-set, neeedle-like spines ; they are generally 2 or 3 lines 



* This species with analytical details is shown (Joe. cit.) in plate 71 A.
