Hardy annuals. Seeds. Common soil.<br />

TRICORYNE. Three species.<br />

Greenhouse herbaceous perennials, except<br />

T. simplex, a green-house biennial<br />

increased by seeds, the other two by<br />

division ; a light rich soil suits them all.<br />

TRIDENTIA. Seven species. Stove<br />

sited in a cabbage or cauliflower, the<br />

young larva immediately eats its way to<br />

the centre, on which it feeds till it is<br />

grown, when it is about two inches<br />

long, greenish or brownish green in<br />

with two rows <strong>of</strong> black spots<br />

on the back. During the winter, it lies<br />

beneath stones or clods <strong>of</strong> earth, and in<br />

April or May it descends a few inches<br />

below the surface, where it changes to<br />

a reddish pupa, from which the perfect<br />

moth emerges in June or July. The<br />

M. F. Otto observes, that—" Seven TRIPHASIA trifoliata. Green-house<br />

species are cultivated in our gardens, evergreen shrub.<br />

namely: Trillium sessile; T. erythro- \oa.m and peat.<br />

carpum; T.pusilium; T. cernuum ; T.\ TRIPTILION.<br />

TRISTANIA. Eight species. Green-<br />

house evergreen trees and shrubs. Half<br />

without covering, in shady places, and ripe cuttings. Loam, peat, and sand,<br />

fiorum. Their cultivation is very sim- |<br />

pie. They grow freely in the open air !<br />

!<br />

in a mixture composed <strong>of</strong> marsh or TRITELEIA. Three species. Haltheath<br />

soil, mixed with river sand. They hardy bulbous perennials. Offsets or<br />

'<br />

bloom abundantly every year, in April"<br />

seeds. Peat, loam, and sand.<br />

and May, and are a great ornament to TRITOMA. Four species. Hardy<br />

our gardens; the tuberous roots spread or half-hardy herbaceous perennials.<br />

rapidly by the formation <strong>of</strong> lateral eyes,<br />

so that after some years, if the plants<br />

have not been removed, they will form<br />

large handsome bushes. The seeds<br />

ripen in August, and if sown immediately,<br />

they will come up the following<br />

year. They may be sown either in the<br />

open ground, in a shady peat border, or<br />

in pots. The stronger seedlings will<br />

bloom in the third season." Gard.<br />
