TIBISirLl. A Guiana name for the fibre 

 of the Ita Palm, Mauritia flexuosa. 



TICK.SEED. Corispermiim ; also Core- 

 opsis. 



TICOREA. A genus of Rutaceco, con- 

 sisting of tropical and subtropical South 

 American trees or shrubs, with white 

 flowers speckled with glandular dots, and 

 arranged ina branched inflorescence. The 

 calyx is fire-toothed ; the corolla funnel- 

 shaped, its limb five-parted ; the stamens 

 five to eight, some of them sterile ; the 

 ovaries five, surrounded by a disk, free, or 

 united by their inner corners; and the fruit 

 capsular, of five carpels. The bark of T. 

 febrifuga, is bitter, astringent, and used 

 in Brazil in fevers. The leaves of T. jas- 

 mini flora are also used medicinally in 

 Brazil. [M. T. M.] 



TIEDMANNIA. A genus of North 

 American orthospermous Umbelliferce es- 

 tablished on a single glabrous herb, with a 

 fistulose stem, and leaves reduced to te- 

 rete nodose petioles. The involucres and 

 involucels are composed of from four to 

 six subulate leaves ; the calyx-limb is 

 five-toothed; the petals broadly ovate, 

 with a narrow inflexed point ; the obovate 

 fruit much compressed dorsally; and the 

 carpels with five somewhat carinate equal 

 ribs, the lateral ones being dilated into a 

 membranaceous margin nearly as broad 

 as the dorsal disk, and the furrows having 

 a single large vitta in each, the commis- 

 sure having two. [W. O.j 



TIEITTE. Strychnos Tieute. 



TIGAREA. Tetracera Tigarea. 



TIGELLATE. Having a short stalk, as 

 the plumule of a bean. 



TIGER-FLOWER. Tigridia. 



TIGER-LILY. Lilium tigrinum. 



TIGER-WOOD. The heartwood of Ma- 

 chorrium Schomburgkii, valuable for cabi- 

 uetmaking, obtained from British Guiana. 



TIGRIDIA. A genus of Mexican bulb- 

 ous herbs of the order Iridacece, having 

 ensiform plaited leaves, and flowers of 

 great beauty, but of a very evanescent 

 character. The perianth has a short tube, 

 and a six-parted spreading limb, the outer 

 segments of which are larger, and the 

 smaller inner ones subpanduriform ; there 

 are three stamens, continuous with the 

 tube of the perianth, their filaments con- 

 nate into a long tube ; the ovary is three- 

 celled, with a filiform stvle as long as the 

 starainal tube, and three filiform bifid 

 stigmas; and the capsule is membrana- 

 ceous, with numerous seeds. The flowers 

 are orange or yellow, richly spotted, 

 whence the name Tiger-flower. [T. M ] 



TIKOOR, TIKUL. Indian names for 

 Gareinm pedunculate. 



* TIKOR. An Indian name for the tubers 

 of Curcuma levcorrhizn ; also for a kind of 

 arrowroot prepared from the tubers. 



TIL, or TEEL. Sesamum orientate and 

 S. indicum, the seeds of which are com- 

 monly known as Til-seed. The black-seeded 

 variety is called Kala-til in India, the white 

 seeded Suffed-til. — BLACK. Guizotia 

 olei/era. 



TIL-TREE. Tilia. — , CANARY IS- 

 LAND. The stiuking-wooded Oreodaplnie 

 fcetens. 



TILE-ROOT. Geissorhiza. 



TILI ACE JS (Elceocarpece, Lindenblooms). 

 An order of polypetalous dicotyledons, 

 consisting of trees or shrubs or very 

 rarely herbs, with alternate stipulate 

 leaves, and usually cymose flowers. They 

 are chiefly characterised by a valvate ca- 

 lyx, indefinite hypogynous'stamens, and a 

 free ovary divided into several cells, with 

 the placentas in the axis. The calyx con- 

 nects the order with Malvaceee and Ster- 

 culiaceo?, from which it is chiefly distin- 

 guished by the stamens. The species are 

 numerous, especially within the tropics; 

 some are natives of the temperate regions, 

 both of the Northern and Southern Hemi- 

 spheres, but none extend into the Arctic 

 Circle, or ascend to great mountain 

 elevations. The genera, about forty in 

 number, have been distributed into two 

 suborders or independent orders, Tiliece 

 and Elceocarpece, upon characters which 

 have failed in so many instances that they 

 have been rearranged in seven tribes.viz — 

 Broicvlowiece, Grewiece, Tiliece, Apeibece, 

 Proclciece, Sloaviece, and Elceocarpece. The 

 most important genera. zre—Broicnloiuia, 

 Grevna, Triumfetta, Cor chorus, Lilhea, 

 Tilia, Apeiba, Prockia, Sloanea, and Elceo- 

 carpus. 



I TILIA. The typical genus of Tiliacece, 



j well known through the Common Lime, so 

 frequently planted as an ornamental tree. 



I It consists of very few species, though a 



j considerable number of supposed ones 

 have been described ; and is entirely con- 

 fined to the temperate countries of the 

 Northern Hemisphere, the Limes being 



j the only European representatives of the 

 order. All the species are large trees, 

 with alternate more or less heart-shaped 

 deciduous leaves, and small yellowish 

 highly fragrant flowers borne in axillary 

 cymes, which have a curious long leaf-like 

 bract attached to their stalks. The flowers 

 have five sepals, as many petals, numerous 

 stamens, and a globular five-celled ovary, 

 each cell containing two ovules ; but four 

 cells are abortive, so that the fruit is only 

 one-celled, and two (frequently only one) 



! seeded. 



| The Common Lime or Linden, T.europcea, 

 attains a height of from sixty toahundred 

 and twenty feet. It is met with generally 

 throughout Europe, except in the extreine 

 North ; one variety of it, the small-leaved 

 Lime, is indigenous to Britain, but the 

 large-leaved variety which is commonly 

 planted, is a native of the South of Europe. 

 Various parts are applied to useful pur- 

 poses. The white soft but close-grained 

 woodis used by carversand turners,"and by
