THE GENUS THUNBERGIA.

in the same manner as recommended for fragrans introduced 
in 1820 from the East Indies. 
T. alcita is a well known summer-flowering climber, and, as 
we have before remarked, well suited for so many purposes. 
The limb of the corolla is a clear buff colour, and the tube or 
throat (eye it is often called) a very dark purple, approaching 
black. The treatment suitable for this differs but little from 
that of fragrans. If it is wished to obtain fine specimens in pots, 
they should be treated precisely the same until they begin to 
bloom, when the greenhouse is the most eligible situation ; or 
if intended for ornamenting the flower-garden, they should be 
kept in small pots until all danger of frost is past, and then 
turned into their respective places. As it is sometimes difficult 
to keep these plants through the winter, it should always be an 
object to obtain seed; and here too is another difficulty: they 
do not usually produce seed when unassisted, or at least to any 
extent, and artificial impregnation is rather a tedious operation. 
The most likely method of obtaining it is to remove the plants 
when in full bloom from the greenhouse to the open air, choos¬ 
ing fine, dry weather, and place them in a situation fully ex¬ 
posed to the sun. Here the fructification is completed. This 
species was brought from the East Indies in 1823. 
T 1 alata alba. — Apparently a variety of alata, though desig¬ 
nated a species : the limb is pure, spotless white; the tube 
dark purple, the same as in the previous species; habit, treat¬ 
ment, and appliances the same. Brought from Madagascar in 
1826. 
T. aurantiaca .—We well remember the “sensation” that 
was created when this fine plant was brought into public notice, 
and well deserving it is of all that was said of it. The limb of 
this is a bright dazzling orange colour, and the tube dark purple. 
Its treatment should be the same as for alata, and it may be 
used for the same purposes. It usually seeds more freely than 
any other species, and this by facilitating its propagation has 
been the means of distributing it wherever plants are admired. 
It emanated from the Epsom Nursery, and was said to be a 
native of Nepal. 
For this and the two preceding species we would recommend 
that the soil contain a larger proportion of leaf-mould ; say leaf- 
mould two thirds, peat and loam one third, with a portion of
