Triteleia

Trochodendron 



TRITELEIA. 



Dwarf, pretty, hardy or half-liardy bulbs (t>rd. 

 Liliacese), now included in Brodiaea. They have 

 usually small, flattened leaves, ranging in the 

 various species from "A" or 4" to 12" in length. 

 The flowers are small and white, yellow, or bluish 

 in colour. Propagation, by separating the bulbs 

 .and taking away the offsets when at rest. Soil, 

 light, sandy loam. A warm border at the foot of 

 a south or west wall makes a suitable home. 

 After the death of the leaves the ground must be 

 kept as dry as possible to ensure the proper ripen- 

 ing of the bulbs. Pot culture in a sunny frame 

 may also be tried.

TRITHRINAX. 



Ornamental stove Palms (tird. Palime), with 

 roundish leaves, which have deeply divided 

 margins. The sheaths of the leaves are conspicu- 

 ous by reason of their intense spininess and the 

 large quantity of loose fibre they produce. They 

 are grown from imported seeds in rich, loamy soil 

 iiniler similar conditions to Thrinax.

 rhi/a aculeata).

 Ivs. 3' long, nearly 

 round. 



TRITICUM. (WHEAT, WHEAT GRASS.) 



With regard to number of species this (ord. 

 (iramiiiese) is quite a small genus, and yet it is of 

 the greatest importance, seeing that the cultivated 

 Wheat is referred to it. 



Almost all the forms of the cultivated Wheat are 

 placed uniler the sprcies vulgare, ffistivum and 

 hybernum being good instances. Dioccum, monoc- 

 cum, and Spelta, which take rank as distinct 

 species, are also closely allied to vulgare. The 

 notorious repens, popularly known as Couch Grass, 

 and probably dreaded more than any other weed 

 that can be named, is now removed from the genus 

 Triticum and placed in Agropymm, the specific 

 name, repens, remaining the same. From a 

 cultural point of view the farmer is more interested 

 than the gardener in the Triticums. For hints as 

 to the extermination of repens, set' COUCH.

TRITOMA (.see KNIPHOFIA). 



TRITONIA. 



Ornamental bulbous plants (ord. Iridese), suit- 

 able for a sunny greenhouse or for warm positions 

 out of doors. The genus is closely allied to 

 Crocosmia, and includes the species which were 

 at one time known ;is Montbretias. The flowering

period extends over several weeks, and the flowers 

 are usually brilliantly coloured. A large number 

 of garden hybrids are in commerce, the majority of 

 which are very handsome. Tritonias, whether 

 grown in pots or in the open border, like rich, 

 light, well-drained soil, and require thorough 

 ripening and a prolonged season of rest.

TRIZEUXIS. 



Falcata is the only species (ord. Orchidaceae). 

 It is an epiphyte, requiring stove culture, of no 

 horticultural value, but interesting to botanists on 

 account of its untwisted ovary, a rare occurrence 

 in the order. It grows about 9" high, and bears 

 green flowers. 



TROCHETIA. 



Evergreen trees or shrubs (ord. Sterculiacese), 

 seldom cultivated. Propagation, by cuttings, in 

 heat. Soil, loam, leaf mould, and sand. 



Principal Species :

Erythroxvlon (now Mel- 

 hauia Erythroxylou). 



TROCHOCARPA. 



A small genus (ord. Epacridese), composed of 

 stiff growing bushes and small trees of no horti- 

 cultural value. 



TROCHODENDRON. 



Aralioides (ord. Magnoliacea;) is the only species 

 of tliis genus. It is an evergreen shrub, hardy in 

 the south of England, grows 12' to Iti' or more in 

 height, and bears terminal racemes of green flowers 

 in spring. The bark is aromatic. It is by no 

 means common. Sandy soil with a little peat 

 suits.
