AUSTRALIAN PLANTS. 167 



139. Solanum oligacantJium, F. Muell. ; stem upright, fruticose ; 

 branches beset with distantly scattered setaceo-subulate prickles ; leaves 

 small, cordate^ obtuse, entire, on both sides as well as the branches 

 covered with a very thin grey toment, hardly armed, short-stalked; 

 peduncles two- or many-flowered, short ; calyx half as long as the co- 

 rolla, with deltoid, acute segments ; anthers yellow, excelled in length 

 by the style. 



This species approaches to Solanum orbicular e (Dunal, Syn. 27), from 

 which it differs chiefly in its not shining toment, and its exact, heart- 

 shaped, somewhat larger leaves. 



To complete my additions to the elaborate description of more than 

 nine hundred Solanum species, published by Professor Dunal in the 

 thirteenth volume of CandoUe's 'Prodromus,' I beg to add yet the 

 diagnosis of an unknown South Australian species, having also given 

 since an account of three others in Professor Schlechtendars 'Linnaea' 

 (vol. XXV. p. 432-434). 



130. Solanum simile, F. Muell. ; unarmed, smooth; stem upright, 

 suffruticose ; leaves narrow-lanceolate, elongate, entire or lobed at the 

 base, thin-venose; corymbs lateral, few-flowered, simple or divided; 

 segments of the half five-parted calyx rounded, apiculate ; berries glo- 

 bose, nodding. 



Hab. On less fertile plains on the Murray and Angas Eiver, on 

 Spencer's and St. Vincent Gulfs, and in Kangaroo Island. 



It is distinct from Solanum laciniatum in its constantly low stem, 

 smallness of all parts, its never pinnatifid leaves, its shorter, nodding 

 pedicels, and smaller, always spherical berries. 



I conclude these contributions towards the Australian Solanece with 

 the remark, that this Order received, by the first and ever-memorable 

 expedition of the unfortunate Dr. Leichhardt, the addition of the genus 

 Datura (in Datura Leichliardtii} , and by the researches of Dr. Bchr, the 

 additional genus Lycium (in i. Australe), both imnoticed not only in 

 the golden ^Prodromus' of R. Brown, but also in Dunal's monograph, 



published in 1852.
