white, of the same shape and size as those of T. alata. The 
plant is of rather more rigid habit, and generally of longer 
duration. It requires to be grown in a stove to flower it well: 
the compost it appears to delight in is a mixture of peat and 
leaf-mould in equal quantities, with a proportion of a third loam 
and sand. It wall seed occasionally: these should be sown 
about the beginning of March in heat; and as soon as the seed 
leaves are thoroughly expanded they should be placed sepa¬ 
rately in small pots, and continued in the same heat until they 
have filled the pots with roots; then let them be placed at once 
in large pots—■ say twelves, and the advantages of the large 
shift will speedily be seen. Through the whole stage of growth 
until the plants have attained maturity, and are beginning to 
bloom, they should be continued in a moist heat, and, if prac¬ 
ticable, let them be saturated (if we may use the term) with 
steam every evening : this will prevent the ravages of that 
minute pest the red spider. Cuttings also may be struck in 
sand under a bell-glass in heat at the same time, and with the 
same treatment they make equally good plants. It will soon 
become evident as they grow that something is required to 
support them ; for this we prefer a flat trellis, as it shows all 
the flowers at one view. They do not require a large one. 
This species has been longer known than any other, having 
been imported from the East Indies in 1796. 
T. grandiflora is much the largest habited of the whole 
genus. The flowers are blue, and also larger than those of any 
other species ; though not being produced so abundantly, it is 
not so generally esteemed. They are more campanulate in 
shape, and are seated on a stiff, erect footstalk. The plant is 
altogether of too coarse a character to render it desirable in 
small collections; yet where there is sufficient space it may be 
grown into a fine specimen. The chief difficulty rests with the 
insectiferous pests that seem to claim this genus as their own. 
The least neglect in the supply of moisture to the foliage de¬ 
stroys all previous care; and from the size which this plant 
attains, it is soon impossible to keep it in a pit where steam is 
most at command: however, if grown in a stove, and attention 
is bestowed in syringing the whole of the leaves every day 
while growing, it will in one season cover a circular trellis of six 
feet circumference. It may be readily increased by cuttings,
