This, as well as the purple-flowered variety of it, were im- 
ported by Mr. Bridges from Bolivia (not Chili, as stated by Mr. 
Smith, in Bot. Mag. under Tab. 4521). The latter is already 
figured in the plate just cited, and we scarcely know which is the 
more striking of the two. The purple-flowered variety has the ad- 
vantage in the colour of the flower, but the present kind produces 
the largest blossoms; the petals are broader in proportion to 
their length, a cream-white gradually passing into the greenish- 
purple of the outer sepals. The spines in the present variety 
are more slender, less curved, of a paler colour, but tipped with 
a darker brown. In other respects the two plants correspond, 
and a full description under Tab. 4521 will equally suffice for 
the present. Its flowering season 1s July. 
Echinopsis, as we there observed, is a genus recently sepa- 
rated from Echinocactus by the Prince de Salm-Dyck, in which 
twenty species are included in the recently published ‘ Cactes 
in Horto Dyckensi cult,’ etc., and these are divided into two 
principal but very unequal groups: “1, TuBERCULAT# : tuberculis
