TOUENIAS.

plants early last summer, and by keeping them in a moist stove 
temperature, soon had a sufficient number to experiment with; 
their propagation, from May to September, is one of the simplest 
and most certain things that ever came under my notice, any 
little piece having two joints, stuck into a pot of light soil and 
covered with a glass, will make a plant in about a week, so that 
next season will surely witness them in nearly all collections. I 
did not observe much difference in the progress of those con¬ 
tinued in the stove, and others grown and flowered in the green¬ 
house, except the more sturdy short-jointed aspect to be reasonably 
expected from the lower temperature, the plants grow quite as 
rapidly with the advantage of being a deeper colour and more 
compact in habit; some others were placed out of doors, but 
they were so small, and not being ready till near the end of the 
season, had not a fair chance, still, from the manner in which 
they got along, I have little doubt that they may be had to orna¬ 
ment the flower-garden, providing well-established plants are 
provided to place out by the beginning of June. T. Asiatica 
was a lovely object in the greenhouse for a long period, the 
blueish purple of its flowers being thrown up, the intense colour 
of the three dark velvet purple blotches on the lobes of the limb, 
the blossoms being produced copiously, and in rapid succession, 
up till a very late period of the season. T. concolor , although 
inferior to the former in point of colouring, is still a beautiful 
thing, and being on the whole somewhat more hardy, will offer 
the greatest prospect of success as a bedding plant; each of them 
possess a rather trailing habit, especially when grown in a warm 
place, and advantage may be taken of this character in the orna¬ 
menting of many peculiar objects; two plants in the stove here 
placed in baskets suspended from the roof, the branches of which 
were allowed to grow downwards, or rather as they pleased, were 
much admired for their graceful appearance, the branches de¬ 
scending by the sides of the baskets, and rooting into the moss 
which lined them, gained additional strength and formed new 
branches, blooming all the time in a most delightful manner; 
concolor appeared to far more advantage when treated in this way, 
than when an attempt was made to train it on sticks, which gave 
a stiff unnatural figure. The soil they seemed to like best was a 
mixture of peat or leaf-mould, loam and sand in equal quantities,
