TRITERNATE. “When a common petiole divides 
into three secondary petioles, which are each sub-divided 
into three tertiary petioles, each bearing three leaflets ” 
(Lindley). ; 
TRITHRINAX (from treis, three, and thrinaz, a 
fan; alluding to the~division and form of the leaves). 
Orv. Palme. A small genus (two or three species) of 
stove, unarmed Palms, natives of Brazil, and one Chilian. 
Flowers small, hermaphrodite; spathes many, the lower 
ones inserted on the peduncle, oblong, obliquely cut, the 
upper ones obliquely truncate; spadices spreading, on 
thick peduncles, with flexuons branches. Fruit baccate, 
one-seeded. Leaves terminal, orbicular-ovate, flabellately 
multifid, glabrous; sheaths fibrous and spiny, erect or 
deflexed. For culture, see Thrinax. 
5 thocoma (spine-covered). fl., spadix branched. l. large, 
flabelliform, cut two-thirds of the way down into numerous 
linear, bifid segments. Caudex dwarf, clothed with the per- 
sistent, netted sheaths, armed with numerous, stout, reflexed 
spines. Rio Grande, 1879. (R. G. 959; G. C. n. s., ix., p. 661.)

T. brasiliensis (Brazilian). /l., spadix within the upper leaves, 
much branched. J. large, 5ft. or more long, flabelliform, nearly 
orbicular ; sheaths at the base composed of fibres, which are at 
first parallel and longitudinal, then obliquely interlaced, and 
finally plaited together at right angles like the pandanus mats 
in which coffee is sent from the Antilles and Bourbon; at the 
summit these stripes unite, forming a series of very long, stout 
spines, abruptly curved downwards, Caudex slender, 6ft. to 
Toft. high, 2in. to in. thick. Brazil, 1875. (I. H. 203.)

TRITICUM (the old Latin name for Wheat, probably 
derived from tritus, crushed or ground). Wheat; Wheat 
Grass. Including Ægilops. ORD. Gramineæ. A genus 
comprising scarcely half a score species of hardy, annual 
or biennial, erect Grasses, natives of the Mediterranean 
region and Western Asia. Spikelets two to five-flowered, 
distichously spicate, sessile, slightly compressed; glumes 
rigid, the two lower ones empty; spikes term‘nal, cylin- 
- drical or elongated; rachis flexuous, alternately excavated, . 
continuous or rarely articulated. Grain ovoid or oblong, 
often villous at apex. Leaves fiat. The plants formerly 
included in British Floras under this genus—viz., T. cani- 
num, T. junceum, and T. repens (Creeping Couch or Cooch 
Grass), the last-named being only too well known—are now 
referred to Agropyrum, the specific names being the same 
in both genera. To T. vulgare, may be referred nearly all 
the varieties of Wheat, a grain well known to every one. 
T, æstivum (summer). A form of T. vulgare. 
T. hybernum (winter). A form of T. vulgare. 
P, (common). Wheat. fl. awned or muticons; spikelets 
usually four-flowered ; valves ventricose, ovate, truncate, mu- 
cronate; spikes tetragonal, imbricated, the rachis tenacious. 
Grain free. h. 3ft. T. estivum and T. hybernum are mere forms 
of this, and 7. di m, F. cum, and T, Spelta (Spelt) are 
TRITOMA. A synonym of Kniphofia (which see). 
TRITOMANTHE. A synonym of Kniphofia 
(which see). 
TRITOMIUM. A synonym of Kniphofia (which |

_ TRITONIA (from triton, a weathercock; alluding to 
_ the variable direction of the stamens in different species). 
_ Syns. Aletris, Waitzia (of Reichenbach). Including Mont- 
Orv. Iridee. A genus including about two dozen 
s of cool greenhouse or hardy, bulbous plants, in- 
us to South Africa. Flower one in a spathe, sessile ; 
Tritonia—continued. 
perianth tube slender, straight, sometimes very short, 
sometimes elongated, rarely loosely incurved at apex; 
limb concave or broadly campanulate, nearly regular or 
slightly oblique, the lobes broad, all similar, or the three 
lower ones thickened or marked with a spot at the base, 
or sometimes slightly smaller; stamens affixed to the base 
of the limb; filaments filiform, free; spathes at the sides 
of the peduncle or on a few scattered branches, short, 
membranous, often three-toothed. Leaves few, narrow- 
linear or broader and ensiform, often falcate. Stem 
simple or slightly branched. The most important garden 
species are here described. All thrive in the cool green- 
house, except where otherwise indicated. The hardy 
species like a well-drained, sunny border, and luxuriate 
in a fairly dry, rich soil. Some of the greenhouse 
species do well in the open air if planted in a shel- 
tered, sunny spot — such as the foot of a south wall; 
they should, however, be housed during winter. When 
grown in pots, Tritonias require plenty of water during 
the period of growth, and a light, airy place close to the 
glass. When the leaves turn yellow, water should be 
gradually withheld, and the roots kept dry, or nearly so, 
until growth recommences. Propagated by division, or 
by seeds.
