base on the underside which may be regarded as modified 
“domatia.”’ Similar structures are present on the leaves 
of several melastomaceous plants, and are particularly 
well seen in Tococa lancifolia. (See Schimper, Plant 
Geography, p. 132.] The domatia of Blakea gracilis, under 
cultivation, are sometimes occupied by the troublesome 
Mealy Bug, Coccus adonidum. 
Blakea trinervia, the only other species yet introduced 
into European gardens, is figured at t. 451 of this work. 
B. quinguenervia, included in some horticultural diction- 
aries, has been referred to Bellucia grossularioides, Triana.
