the Andes within the latitudes of Chile; the latter district, how- 

 ever, has been very little explored, and there is every yeason to 

 believe it will be found by far the most prolific in number of spe- 

 cies of any quarter of the globe. 



According to M, Dunal's distribution of the genus, I find it 

 absolutely impossible to determine the sections to which this 

 large number of new species should be referred. He divides 

 Lijcium into four sections, Schistocalyx^ Eulycium^ Amblymerisj 

 and Lyciobatos :^ Schistocalyx, distinguished by its calyx cleft to 

 the base, comprises only two species, which I have shown do not 

 belong to Lycium^; Amblymeris, another new section, is pre- 



* Huj. vol App. ji,6\. The first plant (my SaZ;?^cAromac^7^a^^m, described 

 in vol. 1. p. 9 and 133; Lycium ciliatum, Schl.) is distinguished by its 

 alternate pointed leaves, nearly as broad as long, almost cordate at base 

 upon a short petiole, with ciliated margins, and covered with short jointed 



:rw; 



calyx split to the base mto distmct hnear segments covered with glandular 

 hairs, especially on its margins, its corolla externally pubescent, with a short 

 tube, and a border of 5 triangular reflected segments, the mouth of the 

 tube closed by a densely villous ring of hairs around the place of insertion 

 of the exserted stamens, the berry encircled by the longer enlarged calyx : 

 such characters are foreign to Lycium, but closely correspond with Salpi- 

 chroma, especially with its section Perizoma ; this is strongly indicated by 

 the triangular segments of the corolla, showing a valvate estivation, while 

 those of Lycium are always very rounded, and remarkably imbricated ; this 

 agam is farther confirmed by the total absence of any induvial remains of 

 the corolla after its fall, which is a constant feature in Lycium, The cha- 

 racters of this plant appeared to M. Dunal so different from others of that 

 genus, as to draw from him the expression " an genus diversum ? " I think 

 there can be Uttle doubt of its being allied to S. rhomboidea (huj, op, vol. i 



p, 7-pl. 1). 



In regard to the second plant, L. serpyllifolium. Dun., I obser\^e, from M. 

 Duna! s description, that its leaves are not fasciculated, its flowers are soli- 



tary 



linear seements, its filaments are recurved 



.„ _ «^»yx.v..ii.o|Juciii,ui auu cmaieuj wiin cuvancatea lobes; these 



are all characters quite foreign to Lycium, and more appertaining to Scro- 

 pfiuiariaceee. ° 



Since the above was written, I Lave seen the original specimen in Dr. 



Hurchell s collection, and find my previous inferences fully verified As the 



plant IS yet otherwise undescribed, I will here annex its characters • it is 



ditticult to imagme upon what grounds it could have been referred to 

 Liycium.
