TRELLIS. 



The name given to framework of various kinds 

 and materials on which plants are trained, such as 

 on the roofs and walls of glasshouses, in pots to 

 support plants, on walls for the same purpose, ot- 

 to screen unsightly objects or form a shelter in the 

 garden. Plain trellises may be used, but the 

 diamond pattern looks best. Balloon shaped or 

 pyramidal trellises are in common use for pots. 

 For a permanency galvanised wire (which ought 

 also to be painted) is good, but many prefer 

 wooden trellis for the ornamental garden or 

 for a shelter. Both wire and wooden trellises 

 can be purchased at a cheap rate, and with various 

 sizes of openings or " mesh." The only advantage 

 of having wooden trellis made to order is that the 

 timber can be painted one or two coats before 

 being fastened together, which preserves it better 

 where the timbers cross. Half-round wooden 

 spars are stronger than the flat. 



TREMANDRA. 



Greenhouse shrubs (iird. Tremandrefe). Propa- 

 gation, by cuttings of young side shoots in sand 

 under a glass. Soil, turfy loam, peat, and sand, 

 with some charcoal and pieces of brick or broken 

 pots. 



Trefoil (sec Trifolium). 



Trefoil, Jiird's Foot (see Lotus cornwnlatus). 

 Trefoil, (iolden (see Anemone Jfejiatica). 

 Trefoil, Milk (see Cytisus). 

 Trefoil, Moon (Medirago arbarea). 

 Trefoil, fre-nted (see Melilotm). 

 Trefoil, Minibby (Jasminnm frutieans and Ptelea 

 trifoliata). 



Principal Species : 

 Huegelii of gardens (now 



Tetratlieca hirsuta). 

 stelligera, '!' ', sum., pur- 



plish (ti/n. oppo&iti- 

 folia). 



verticillata (now Platy- 

 tlioca galioides). 



TREMBLING TREES. 



Several trees which move their leaves at the 

 slightest breath of wind are popularly known as 

 Trembling Trees. The best known of these are 

 Populus tremula and P. tremuloides, the former 

 jeing the well-known Aspen. 



TRENCHING. 



An important and valuable operation, but one 

 often neglected because of the labour involved. 

 Where the subsoil is inert or of bad quality it is 

 an error to adopt trenching at first, and bastard 

 trenching (which see) ought to be performed in the 

 first place until the lower spit of soil is ameliorated. 

 At the beginning make a trench two spits or three 

 spits deep and 20" or so wide, wheeling the soil thus 

 removed to the farther end of the ground to be 

 trenched. After this, measure out another trench 

 with:the line, and fill the bottom of the first trench 

 with' the soil from the top of the second one, that 

 from the bottom of the second going on the top, 

 leaving it rather rough during winter. Manure 

 and surface rooting weeds may be buried at the 

 bottom of the trench. Autumn is the most suitable 

 season. 



TREVESIA. 



Handsome foliage stove shrubs or trees (tint. 

 AraliaceEe). The flowers are of little consequence. 

 Propagation, by cuttings in heat. Soil, loam, leaf 

 soil, and sand. 



Principal Species : 

 emiueus, Ivs. palmatifidly Ivs. palmate or digitate 



divided and serrated. ' (//. insignis). 



pahnata, 10', Men., grn., suuclaica. resembles palm- 

 ata. 



TREVOA. 



Greenhouse trees (prd. Rharanese). The only 

 species introduced, trinervia, is lost to cultivation. 



TREVORIA. 



A recently introduced genus of Orchids (ortl. 

 Orchidaceas), named in honour of Sir Trevor Law- 

 rence, Bart. Chloris, the only known species, ia 

 not yet sufficiently in commerce to test its full 

 cultural requirements. It has racemes of yel- 

 lowish flowers. 



TREWIA. 



Three or four species of stove trees (ord. En. 

 phorbiacefe). Propagation, by cuttings in sand 

 under a glass. Soil, loam and peat, with sand. 



Principal Species : 



nudiflora. 'A' to 8', My., st.. grn. 



TRIANEA. 



The correct name of the floating aquatic plant 

 known in gardens as Trianea bogotensis is Limno- 

 bium bogotense. Propagation, by runners. It 

 requires stove or greenhouse treatment. 



TRIAS. 



Stove Orchids (ord. Orchidacese) of creeping or 

 tufted habit, with one flower on a leafless scape. 

 Grow on blocks or in pans with sphagnum and 

 peat. 



Trerirana (of Willdsnom, sec Achiniencs}.
