Taccarum

Talauma 



TACCARUM. 



Stove, perennial, tuberous herbs (jird. Aroidese), 

 witli large, ornamental foliage. The leaves are 

 usually divided and subdivided into a large number 

 of segments, which gives them a very distinct 

 character. A long rest is required after growth. 

 Propagation, by imported tubers. Soil, rich loam, 

 thoroughly drained. 



Principal Species : 



cylindricum, 8' to4',grn., Wanningii, 3', Ivs. 2' to 

 Ivs. 2' across (<.'/. 2V across, 



peregrinum). weddelianum, 3', spr. , 



br. , Ivs. 'I' to 2 . ' across. 



TACHARDIA. 



An important genus of scale insects, the species 

 lacca providing lac, one of the principal ingredients 

 of varnish, French polish, and similar preparations. 

 In the larval state they settle upon twigs and 

 branches for the purpose of sucking food from the 

 plant. When feeding, the lac is formed round 

 their bodies, and eventually the females die. The 

 encrusted twigs are imported as " stick lac." In 

 addition to producing lac, the females form the 

 basis of a dye. 



TACHIGALIA. 



Hare stove shrubs or small trees (nrd. I/egu- 

 minosic) of no special horticultural value. Prop- 

 agation, by cuttings. Soil, fibrous loam and peat. 



Principal Species : 



multijngu, 20', sum., yd. paniculate, 'JO' to :>()', 

 sum., yel. 



TACIADENUS. 



I'ink, blue, or white flowered stove herbs or 

 sub-shrubs (ard. Gentianea;). Increase, by division, 

 or by cuttings in sandy soil in a close case. Soil, 

 equal parts fibrous loam and peat, with sand. 

 Keep on the dry side in winter. 



Principal Species : 



CJirinatus, K', Oct., M. gracilis. 1', Sep., pk. 



TACSONIA. 



Ornamental greenhouse climbers (itrd. Passi- 

 floreie). The principal difference between Tacsonia 

 and Passittora is found in the elongated tubular 

 calyx of the former. Most of the species have 

 very deeply lobed leaves. The most suitable 

 position for Tacsonias is the roof, so that the 

 branches will hang in a graceful manner, and show 

 the full beauty of the pendulous flowers. Propaga- 

 tion, by cuttings of young shoots 4" long in sandy 

 soil in a close case. Soil, fibrous loam, well-rotted 

 manure, and leaf mould, with sand. Insignis is 

 benefited by an addition of peat in equal bulk to 

 the loam. The best results are always obtained 

 from Tacsonias when they are planted out in a 

 thoroughly drained border ; from 12" to 18" of soil 

 is quite sufficient, and a border 2' to 3' wide gives 

 ample space. Two good shoots should be en- 

 couraged to grow up each rafter. Monthly 

 thinnings of the shoots will be necessary to allow 

 full light and air to those required for flowering. 

 An annual spurring back in January to within two 

 or three eyes of the old wood is necessary. Mealy 

 Bug and Heel Spider are the two worst insect 

 pests. After three years' growth the surface soil 

 to a depth of 4" should be removed, and replaced 

 with two parts good new loam to one part well- 

 rotted manure-.

T^ENITIS. 



Stove Ferns (onl. Filices), of interesting appear- 

 ance, but not in general cultivation. Propagate 

 by division, and grow in a warm house, using sandy 

 peat with a little loam. The following figures 

 apply to the length of the fronds. 



Principal Species : 



augustifolia, 1' to K'. lanceolata, 6" to 12", thick 



blcchnoides, 1' to 2', ill texture.

TAGETES. 



Hardy or greenhouse annuals and sub-shrubs 

 (iifil. Compoeitsa). Several species are largely 

 used for summer bedding. Propagation, by seeds 

 sown indoors, pricked off in boxes, and transferred 

 to the open borders in May, or sown out of doors 

 in April ; the perennial species by cuttings. Any 

 good garden soil is suitable. (See also MARI- 

 GOLD.)

TAINIA. 



Stove Orchids (ord. Orchidacea;), one or two 

 species only being cultivated. They may be 

 grown in perfectly drained pots of fibrous loam 

 mixed with crocks, charcoal, and sandstone. The 

 method of culture recommended for Calanthe is 

 suitable.

Stove or greenhouse evergreen trees (aril. Mag- 

 noliaceae), with pretty, fragrant, Magnolia-like 

 blossums, which last in good condition for a very 

 short, time. Propagation, by seeds. Soil, two 

 parts fibrous loam, two parts peat, and one part 

 leaf mould, with sand.
