ALFRED REHDER. 



ZENOBIA (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). Ericaceae. 

 Ornamental shrub grown for its handsome white flowers, 

 and also for the foliage which is covered with a bluish 

 white bloom in one form. 



Deciduous or half -evergreen : Ivs. alternate, short- 

 petioled, crenulate or entire: fls. in axillary clusters 

 forming terminal racemes on the upper part of last 

 year's branches; calyx 5-lobed, with short valvate 

 lobes; corolla campanulate, as broad as high, obtusely 

 5-lobed; stamens 10; anthers with 4 slender awns: caps, 

 depressed-globose, obscurely 5-lobed, somewhat cari- 

 nate at the dorsal sutures, loculicidally 5-valved; seeds 

 numerous, small, oval, angled. One species in N. 

 Amer., closely allied to Andromeda and Pieris but 

 chiefly distinguished by the open-campanulate fls. and 

 4-awned anthers. 



Zenobia is a low bush with medium-sized short- 

 petioled leaves entire or nearly so and with handsome 

 white nodding flowers in clusters along the upper part 

 of last year's branches. It is hardy as far north as 

 Massachusetts, and a very handsome shrub for borders 

 of shrubberies, particularly when in bloom; the glau- 

 cous form is one of the most conspicuous shrubs with 

 light-colored foliage. After flowering, the flower-bear- 

 ing part of the shoots should be cut off. Zenobia is also 

 recommended for forcing. It thrives best in a sandy or 

 peaty soil. Propagation is by seeds and by layers; 

 also by cuttings of half-ripened wood in July placed 



in gentle heat, or by greenwood cuttings from forced 

 plants. See, also, Andromeda and Pieris for culture.

 eda pulverulenta, Bartram. A. speciosa, Michx. A. 

 glauca, Hort. A. Candida, Hort. A. deaVbata, Lindl.). 

 Figs. 4043, 4044. Shrub, 2-4 ft. high, with upright or 

 arching branches: quite glabrous: Ivs. oval to oblong, 

 obtuse 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 white, J^in. across. May,

ZEPHYRANTHES (Greek, flower of the west wind). 

 Syn. Atamosco. Amaryttiddceae. ZEPHYR FLOWER. 

 FAIRY LILY. Half-hardy tunicate-bulbous herbs, grown 

 in the greenhouse, in window-gardens, and in the gar- 

 den for summer- and autumn-blooming. 



Leaves narrow, usually contemporary with the fls.: 

 peduncle elongated, slender, hollow; spathe membra- 

 nous, tubular, apex bifid: fls. white, red, or yellow, soli- 

 tary in the spathe; perianth funnel-shaped, erect or 

 slightly inclined, tube short or elongated, segms. sub- 

 equal; ovary 3-celled: caps, subglobose, loculicidally 

 3-valved. About 53 species, natives of the warmer 

 regions of Amer. A general revision of Zephyranthes is 

 found in Baker's Handbook of the Amaryllideae, 1888, 

 where the following subgenera are made: Subgenus 

 ZEPHYRANTHES proper. Fl. erect; tube short; stamens 

 inserted near its throat. Subgenus ZEPHYRITES. Fl. 

 slightly inclined; tube short; stamens inserted near its 

 throat; style more declinate than in the other two sub- 

 genera. Subgenus PYROLIRION. Fls. erect; tube longer, 

 dilated in the upper half; stamens inserted at the middle 

 of the perianth-tube. For the further separation of the 

 species, Baker uses the characters which appear in the 

 key below, except the foliage-characters and the color 

 of the fls. However, the genus may be readily separated 

 into 3 sections based on the color of the fl., and this 

 arrangement is here used as being more convenient to

the horticulturist. The seasons of bloom indicated 

 herein are those for localities where the plants will 

 thrive outdoors the year round. For an account of 

 bigeneric hybrids of Zephyranthes and Cooperia, see 

 Lancaster, Journ. Roy. Hort. Soc. 38, p. 531. 



The zephyr lilies must be wintered in a place free 

 from frost, and as the best kinds are natives of swampy 

 places it is fair to presume that they will need more
