ZEPHYRANTHES

mens 4-5; styles 2: fr. a 1-seeded drupe, usually broader 

 than high, oblique, with the style eccentric. Z. 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.

 Fig. 2786. Tree, attaining 

 100 ft., with broad, 

 round - topped head ; 

 branches slender : lvs. 

 short - stalked, ovate to 

 oblong-ovate, acuminate, 

 rounded or slightly cor- 

 date at the base, sharply 

 and coarsely serrate, with 

 acuminate teeth, pairs of 

 veins about 10, somewhat 

 rough above, almost glabrous, 1-2VS in. long, on fertile 

 branches, 2-5 on sterile branches. April, May. Japan.

crenata, Spach (Z. carpinifdlia, C. Koch. Pldnera 

 Rlchardi, Michx. Aoelicea ulmoides, Kuntze). Tree, 

 attaining 80 ft., with slender branches forming an oval 

 or oblong head: lvs. oval or ovate to oblong, slightly 

 cordate or rounded at the base, coarsely toothed with 

 obtusish teeth, with 0-8 pairs of veins, usually almost 



cies, supposed to be Japanese; it is distinguished from Z. cre- 

 nata chiefly by the lvs. being somewhat smaller, more pubes 

 cent and rough above. Var. Verschaffelti, l>ipp CUlnraa 

 Verschaffeltii, Hort.), has the lvs. deeply incisely dentate and 

 broadly euneate at base. ALFRED Rehder.

2787. Forced plant of Zenobia spec 



ZEN0BIA (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). Erieacece. 

 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 Andromeda and Pieris but chiefly distinguished 

 by the open -campanulate fls. and 4-awned anthers; 

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

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

 10; anthers witb 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. 



specidsa, Don (Andrdwrdn spfciosu, Michx. A. ens- 

 sinefblia, Vent.). Figs. 2787, 2788. Shrub. 2-4 ft. high, 

 with upright or arching branches: quite glabrous : lvs. 

 oval to oblong, obtuse or aeutish, 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 

 white, Yn in. across. Mav, June. N. C. to Fla. B.M.

 23, suppl. 28 May. — Var. pulverulenta, Michx. 

 edit pulveruldnta, Bartr. A. glttitca, Hort. A 

 Hort.). Foliage covered with chalky-white o: 

 bloom. Gn. 24:420. B.M. 667. A. dealbata, Lindl., is 

 a form with similar foliage and the corolla 5-parted al- 

 most to the base. B.R. 12:1010. Var. nitida, Michx. 

 (Var. nitda. Vent, Var. rh-idis, Hort.), has green foli- 

 age without bloom. Alfred Rehder. 



ZEPHYRANTHES (Oreek, flower of the west wind). 

 AmaryllidAcece. Zephyr Flower. Fairy Lilt. 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 lvs. 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.
