An exceedingly pretty Melastomaceous plant, probably 
not an unfrequent native of Brazil. It was first detected 
by Mr. M‘Rae at St. Catherine’s, who was the Collector 
there for the Horticultural Society ; and since, on the same 
line of coast, by Mr. T'weepte, from whose seeds it was 
raised at the Glasgow Botanic Garden, and the little bushy 
plants are pretty thickly studded with their delicate flowers 
in July and August. It seems to require the heat of the 
Stove to bring it to perfection.
