Ten species. Stove evergreen climbers, except T. auran-tiaca, a green-house herbaceous perennial. Cuttings or seeds. Sandy loam and leaf mould.

Mr. MacIntyre says, that the species of this genus, "though usually grown in a stove, will flower freely in a greenhouse, or even when they are planted out in the open border, during the summer months: if the situation is sheltered, and exposed to the influence of the sun, they will flower well. In propagating those that are intended for planting out, take off the lateral shoots when they are of a sufficient length, which, if possible, should be done in March, so that the plants may have attained a medium size before they are put out; pot them in equal quantities of peat and sand, then plunge them in a hot-bed, and they will strike root in a week or two. When they are rooted, pot them off into small pots filled with good rich loam and leaf-mould, mixed with a little sand; then replace them in the pit or frame until the middle of May, when, if the weather is favourable, they may then be planted out. If the soil is not naturally good, it should be made so; and as the plants advance in growth, they should be trained to some kind of support, which may be of any shape that fancy may suggest. If the season is dry, they should be watered and syringed.

About the middle of October, take up the plants with good balls, re-pot them, and place them in the green-house. After they have been there for a short time, they may be removed to the stove, where they will keep gay for the greater part of the winter.

"T. alata has a beautiful effect when it is planted out on a rock-work, where the plant appears in its natural character, clinging to the various projections, which it quickly covers." - Gard. Chron.
