A very beautiful Mexican Melastomaceous plant, inhabiting 
mountains about Xalape, at altitudes of six to eight thousand 
feet, and although hitherto kept in the stove with us, there is no 
doubt of its succeeding well in a cool greenhouse. It has been ~ 
circulated, judging by the appellation which we have received 
with it, as “ Heteronoma subtriplinervium, ’—the genus of which 
is quite different ; and the specific name implies a character, 
common to most of the Order Melastomacee, but quite at 
variance with the species and the genus to which our plant be-. 
longs. Our plants have flowered in the autumnal and early 
winter months, and prove exceedingly ornamental at that un- 
favourable portion of the year. We owe the possession of our 
FEBRUARY Ist, 1860.
