This pretty and very distinct Opuntia is said to be a native of 
Brazil. Our collection is indebted for the possession of it to the 
Royal Gardens of Herenhaussen. It blossoms freely, and the 
ordinary-looking stems and branches are ornamented by the 
variegated red and yellow and rather copious flowers in Sep- 
tember and October. In the generic character we follow 
that given by the venerable Prince de Salm-Dyk in his recently- 
published volume entitled  Cactez,”” a work which ought to be 
in the hands of every cultivator of this curious tribe of plants. 
Drscr. Plant small, one to two feet high, erect, branched, 
branches erecto-patent, cylindrical, rather of an ashy-green colour, 
destitute of tubercles, obtuse at the apex. Areoles scattered, 
forming white downy tufts of wool, bearing six to eight unequal, 
brown, small aculez, the largest less than half an inch long. 
Flowers moderately sized, clustered at the apex of a branch. 
Ovary obovate, not scaly but areolated, and bearing aculet 
like the branches, and, what is remarkable, after the floral 
OCTOBER Ist, 1850.
