Anthers long, linear, deep yellow, opening with two pores 
at the extremity. Pistil: Germen globose: Style rather 
longer than the stamens: Stigma obtuse. Berry orange- 
colour, glabrous, about the size of a large pea. 
Introduced to the Horticultural Society of London, by 
Mr. M‘Rag, from Chili, and to the Botanic Garden of Glas- 
gow, from Mendoza, by Dr. Gitties. Our dried specimens, 
in the Herbarium, are from this latter gentleman, gathered, 
in November 1820, near Rio Saladillo, and the remark is 
added, that “ it is the same species which is so common all 
over Mendoza, of which the unripe berries are used instead 
of soap, to wash woollens, and which are called Killo-Killo.” 
It is from this peculiar property, that we have taken the 
liberty of altering the MSS. name of Mr. Linpzey (S. deal- 
batum) to S. saponaceum. 
Our dried specimens prove most clearly how liable this 
plant is to vary in the number of its aculei; some. being 
almost destitute of them, whilst others have the stem, peti- 
~si and underside of the mid-rib thickly clothed with 
them. 
Its nearest affinity is perhaps with the Sot. eleagnifolium 
of Cav.; but that has the lower leaves sinuated, the corolla 
much larger, its laciniz less deep, and its colour blue. 
In our stoves, where the plant has been hitherto culti- 
vated, it flowers in the month of October.
