P. Browne remarks that this plant may be deemed a variation of 
T. longifolia, they being so much alike in habit, the form of the 
leaves is almost the only difference ; that they are always cor- 
date, the upper ones only being ovate and sessile; the corollas 
are also rather larger.

lary ; segments of corolla ovate, acute, erect; stamens much ex- 
serted. h. S. Native of Jamaica, on the blue mountains.

Cult. These are elegant shrubs when in blossom. They 
will grow freely in a mixture of peat and sand, mixed with a 
little loam ; and cuttings strike root readily in sand under a 
hand-glass, in heat. The species are difficult to keep through . 
the winter in this country, being very apt to damp off; but 
to prevent this, as much as possible, they should be kept rather 
dry in damp weather.
