TRICORYNE (from treis, three, and koryne, a club; 
in allusion to the form of the capsules). Orp. Liliacee. 
A genus embracing six species of greenhouse perennials 
with fibrous roots, limited to Australia. Flowers in 
terminal umbels, with small, imbricated, scarious bracts; 
perianth spirally twisted after flowering, but at length 
deciduous, of six narrow, three or five-nerved segments ; 
stamens six, hypogynous. Leaves few and Grass-like or 
all reduced to searious scales. Stems usually wiry and 
branching, the branches often clustered. It is doubtful 
whether any of the species are in cultivation. T. elatior 
thrives in light, rich soil, and may be increased by 
divisions. : 
T. elatior (taller). f., perianth white, usually about iin. long; 
umbels, three, four, or six-flowered. June. Zl., lower oyes often 
Grass-like, 2in. to 4in. long, the upper ones, and sometimes all, 
reduced to short scales. Stem lft. to 2ft. high. 1824. 
TRICRATUS. A synonym of Abronia (which see). 
TRICUSPIDARIA (from tricuspis, three-pointed ; 
alluding to the petals), Syn. Tricuspis. ORD. Tiliacee. 
A small genus (two species) of Chilian, greenhouse trees. 
Flowers rather large; calyx campanulate, truncate, ob- 
soletely five-toothed, afterwards cut and deciduous; petals 
five, three-toothed or three-lobed, induplicate - valvate ; 
stamens numerous, inserted above the torus; peduncles 
axillary, solitary, one-flowered. Leaves alternate and 
opposite, serrated. T. hexapetala, the only species in- 
troduced, is a very beautiful, greenhouse shrub. For 
culture, see Correa. 
T. hexa (six-petaled). jl. red, on long peduncles. Cap- 
sule sub-rotund, silky-pilose. l. oblong-lanceolate, serrated or 
rarely entire. See Fig. 99. (Gn., Noy. 1880, under name of 
Crinodendron Hookerianum.)

TRICYRTIS (from treis, three, and kyrtos, convex ; 
alluding to the three outer perianth segments having 
bags at their base). Syns. Compsanthus, Compsoa. 
ORD. Liliacee. A small genus (five species) of half- 
hardy perennials, with shortly-creeping rhizomes, natives 
of the Himalayas, Japan, and China. Flowers few, rather 
large, on longish pedicels; perianth 
spotted within, campanulate; segments distinct from 
the base, lanceolate, the outer ones saccate at base, the 
inner ones flat, all spreading above; stamens six, hypo- 
gynous; inflorescence terminal or in the upper axils, 
loosely dichotomous, erect. Leaves alternate, ovate or 
oblong, contracted, sub-sessile, or cordate-amplexicaul at 
base. Stem erect, simple below the inflorescence, leafy. 
The three species introduced are ornamental plants. 
They thrive in a compost of sandy loam and peat, and 
require the shelter of a greenhouse or cold pit in winter. 
Propagation may be effected by offsets. `

species of hardy, perennial herbs, natives of tropical 
America. Flower-heads yellow, or the disk greenish, 
mediocre, long-pedunculate, heterogamous; ray florets 
ligulate or sub-bilabiate, the outer lip large, sometimes 
three-toothed, three-cleft, or three-parted, the inner smaller — 
or minute, two-lobed or two-parted, sometimes obsolete ; 
involucral bracts in few series; receptacle flat or convex; 
achenes turbinate, silky-villous. Leaves opposite, incised- 
toothed or pinnately dissected; segments few, narrow. 
The species possess but little beauty, and require ordinary 
culture. Propagated by divisions, or by seeds.
