The genus Ovalis, once a favourite amongst amateur 
horticulturists, has of late years experienced the neglect that 
has overtaken so many interesting classes of herbaceous 
plants. Upwards of one hundred and thirty species, chiefly 
natives of South Africa, have been figured as under cultiva- 
tion in Europe. By far the larger number of these are con- 
tained in the beautiful Monograph of the genus published by 
the elder Jacquin in 1794, from specimens cultivated in the 
Imperial Gardens at Vienna. In 1808 fifty-eight species 
were in the Kew collection, where there are now only thirty ; 
and no species has been figured in this Magazine for a quarter 
of a century, when (1850) the lovely 0. elegans of the Andes, 
Tab. 4490, appeared. Happily a love of the genus lingers 
amongst scientific horticulturists, to one of whom, G. Munby, 
Esq., I owe the opportunity of figuring the present species. 
Oxalis arenaria is a native of Chili, where it is widely 
distributed, being found in sandy pastures near Valparaiso, 
Santiago, and other localities. It has also been gathered on 
the Andes of Bolivia, by Mandon, in the neighbourhood of 
Sorata, at an elevation of between eight and nine thousand 
feet above the sea-level. The specimen here figured flowered 
with Mr. Munby in March. :
