ZELKOVA 



mens 4-5; styles2: fr. a 1-seeiled drupe, usually broader 

 than high, oblique, with the style eccentric. X. acumi- 

 nata is an important timber tree; the wood is very dur- 

 able, and considered the best building material in Japan. 

 The young wood is yel- 

 lowish white in color; 

 the old wood is dark 

 brown and has a beauti- 

 ful grain.

ZENdBIA (after Zenobia, queen of Palmyra, who 

 lived in the third century; a fanciful allusion to her 

 having been chained as was Andromeda, whose name 

 is commemorated by a closely allied genus). UricAcece. 

 Ornamental low deciduous or half-evergreen shrub, with 

 alternate, short-petioled, simple and white, campanu- 

 late, nodding flowers arranged in clusters along the last 

 year's branches. Hardy as far north as Mass., and a 

 very handsome shrub for borders of shrubberies, par- 

 ticularly when in bloom; the glaucous form is one of 

 the most conspicuous shrubs with light-colored foliage. 

 Zenobia is also recommended for forcing. It thrives 

 best in a sandy or peaty soil. Prop, by seeds sown in 

 spring and by layers; also by greenwood cuttings from 

 forced plants. See, also, Andromeda and Pieris for 

 culture. Monotypic genus native of N. America, closely 

 allied to Androiiieda and Pieris but chiefly distinguished 

 by the open -campanulate fls. and 4-a\vned anthers; 

 calyx 5-lobed, with short valvate lobes; corolla cam- 

 panulate, as broad as high, obtusely 5-Iobed; stamens 

 10; anthers with 4 slender awns: capsule depressed 

 globose, obscurely 5-lobed, somewhat carinate at the 

 dorsal sutures, dehiscent into 5 valves: seeds numer- 

 ous, small, oval, angled. 



Bpecidsa, Don (Andromeda speciosa, Michx. A. ras-

 with upright or arching branches: quite glabrous: Ivs. 

 oval to oblong, obtu.se or acutish, crenulate or finely 

 serrulate, often covered more or less with glaucous 

 bloom, 1-2 in. long: fls. on slender nodding pedicels, 

 clustered and forming racemes 2-5 in. long ; corolla

ZEPHYEANTHES (Greek, tiotver of the west wind). 

 Amariillid(icea>. Zephvr Flower. Fairt Lily. About 

 three dozen species of bulbous plants native to the 

 warmer parts of America. Unfortunately they are not 

 quite hardy, but some of them are very satisfactory 

 plants for window-gardens, resting somewhat in winter 

 and blooming in summer under such treatment. They 

 all have linear Ivs. contemporaneous with the fls., and 

 slender scapes about 6-9 in. high, crowned by solitary 

 6-lobed fls. of white, rose or yellow. The fls. are 1-3 in. 

 across. Other generic characters: perianth regular, 

 erect or suberect : corona none ; anthers dorsifixed, 

 versatile: ovules many, superposed: seeds black, flat.
