 purple, the obovate obtuse blade of the outer segments 

 light purple; inner segments "folded together in such 

 a manner as to form a sunken longitudinal tube down 

 the center, the dilated sides at the outer end of the 

 tube approaching each other in the form of two cheek- 

 like prominences, — these are colored white, purple and 

 yellow, while the small rounded terminal blade is a 

 deep purple." Mts. of Jolisco, Mex. G.P. 2:413. -Of-

T. ailrea, Hort., is Cypell.-i plumbea, but it is not in the Amer- 

 ican trade. See page 429.— r. Hoiutei, Roezl. is Hydrot^enia 

 Van-Houttei. See page IST.—T. Meleagris. Hort., is also a Hy- 

 drotsenia (H. Meleagris. Lindl.), but is not in the American 

 trade. B.R. 28:39.— T. violacea. Sehiede. One of the Beatonia 

 section: slender, narrow-lvd.: Hs. 2 in. across, violet, spotted

TlLIA (the classical Latin name). Tilidcem. Lime. 

 Linden. Basswood. Whitewood. Trees distributed 

 generally throughout the northern temperate zone, with 

 soft, light, white or light-colored wood, tough librous 

 inner bark, serrate alternate petiolate, mostly cordate 

 Ivs. and caducous stipules: inflorescence cymose, the 

 peduncle attached to, or adnate with, for about half its 

 length, a ligulate membranaceous bract: fls. small, yel- 

 lowish; sepals 5; petals 5; stamens many, with long 

 filaments nectariferous: fr. globose, nut-like. In some 

 species, small petaloid scales are found among the 

 stamens. 



The soft white wood of several species is in great de- 

 mand for making fruit, honey and other light packages, 

 the facility with which the wood is cut into veneers 

 rendering it admirable for such use. The fibrous inner 

 bark is used as a tying ma- 

 terial and in the manufac- 

 ture of Russian bass or bast 

 mats. Extensively planted 

 as an ornamental tree and 

 for bee pasture. As a 

 source of honey .supply per- 

 haps no other plant excels 

 it, as under favorable con- 

 ditions the nectar sometimes 

 drips from the flowers in a 



Nearly all the species are 

 of rapid growth and not 

 very particular as to soil. 

 Propagated by seeds, layers 

 or grafting. In layering, it 

 is usual to twist the branch 

 layered before covering it. 

 The method known as 



IS cut close to the ground 

 and the " stools " or suckers 

 are banked up with earth 

 until they root, when they are severed from the old 

 stump and planted in the nursery rows. Rare varieties 

 are usually increased by budding or grafting. 



Much confusion exists in the trade names, especially 

 in the European varieties. This is no doubt largely 

 due to the fact that at least three species have been 

 sent to this country under the name of T. Miiropcea.
