year. They are now 12 feet high and 6 to 8 inches in 

 diameter at base. Oleanders need no attention here, 

 and are as readily propagated from hardwood cuttings 

 as willow. They are very floriferous, and the inflores- 

 cence comes out in large heavy heads, necessitating 

 a close pruning to make them self-supporting. 



A. Fls. not scented. 



Oleander, Linn. (N. lauriforme, Lam.). OLEANDER. 

 ROSE BAY. (Another plant called "Rose Bay" is 

 Epilobium angustifolium.) Fig. 2476. Lvs. in 2's or 

 3's, lanceolate: appendages of the anthers scarcely pro- 

 truding; segms. of the crown 3-4-toothed. Medit. 

 region, Orient. Gn. 51, p. 81 (fine trees in vases). A.F. 

 10:265 (Bermuda shrub with a spread of 25 ft.). L.B.C. 



2476. Spray of oleander Nerium Oleander. ( X \i) 



7:666 (var. Loddigesii, with a variegated fl. and the 

 appendages entire, ovate and obtuse). N. dlbum, N. 

 atropurpiireum, N. cdrnewn and N '. roseum, Hort., are 

 doubtless varieties. The plant is common in subtropi- 

 cal and tropical countries, sometimes planted in hedges, 

 and sometimes runs wild. 



AA. Fls. scented. 



odorum, Soland. SWEET-SCENTED OLEANDER. 

 Stout erect shrub: Ivs. in 3's, linear-lanceolate: fls. 

 rosy pink, 2 in. across, in clusters of as many as 80, 

 fragrant; appendages of the anthers protruding; segms. 

 of the crown 4-7, long and narrow. Persia, India, 

 Japan. B.R. 74 (fls. double). B.M. 1799 and 2032. 

 G.C. III. 50: suppl. July 8, 1911. A less robust plant 

 with Ivs. commonly narrower and more distant, and 

 angled branches. In wild plants the calyx-lobes of N. 

 Oleander are spreading; of N. odorum erect. It has the 

 same range of color as the above, and single and double 

 forms. Prop, by layers or cuttings.

NERTERA (Greek, lowly; referring to the habit). 

 Rubiacex. Creeping herbs, of which one is grown for 

 its handsome profuse berries. 



Nerteras are slender perennials, with small opposite 

 Ivs. which are stalked or not, ovate or ovate-lanceolate, 

 glabrous or somewhat pilose; stipules present: fls. axil- 

 lary or terminal, hermaphrodite, inconspicuous, ses- 

 sile; corolla 4- or 5-lobed; stamens 4 or 5, inserted in 

 base of tube of the tubular or funnel-shaped corolla, 

 the anthers exserted; ovary 2-celled: drupe 2-seeded 

 (two 1-seeded pyrenes), fleshy. Species about 8, 

 widespread in the southern hemisphere. 



depressa, Banks & Soland. BEAD-PLANT. Glabrous: 

 variable in size, sometimes forming patches: sts. 6-10 

 in. long, 4-cornered: Ivs. 2 lines long, broadly ovate, 

 acute or obtuse, leathery or almost fleshy; petioles 

 about as long as the blades; stipules very small: fls. 

 solitary, greenish. B.M. 5799. F.S. 21:2167 (charm- 

 ing). F.W. 1875:257. The bead- or coral-bead-plant 

 is a hardy perennial alpine or rock-plant which forms a 

 dense mat of foliage covered with orange-colored trans- 

 lucent berries the size of a pea. It ranges throughout the 

 Andes, from the tropics to Cape Horn. It also inhabits 

 Tristan d'Acunha, and the mountains of New Zeal, and 

 Tasmania. It is prop, by seed or division. The plant 

 needs a sandy soil, with some leaf -mold, and prefers shade 

 hi summer and may need some winter covering in the 

 N. It makes a good house plant and well-fruited speci- 

 mens are occasionally used abroad in fancy bedding 

 as a novelty. The fr. may last from midsummer well 

 into the whiter. In S. Calif., N. depressa grows well hi 

 the open if it is kept moist and does not receive the 

 direct rays of the sun. WILHELM MILLER.

NERVILIA (name refers to the nerved Ivs.). Orchi- 

 ddcese. By some authors made a section of Pogonia 

 with fl. -scape bearing only scales and not Ivs., the foliage 

 coming later and separately, stigma broad and lip 

 elongated: the small grayish or reddish fls. are some- 

 tunes solitary or twin but usually in a short raceme, 

 nodding: Ivs. radical, usually broad, sometimes colored 

 or marked. The species are about 20, from Trop. Afr. 

 to China. They are very little known in cult.

NEUWIEDIA (named for Prince Maximilian von 

 Newied). Orchidaceae. A half-dozen Malayan terres- 

 trial orchids with short caudex and leafy sts.: Ivs. 

 lengthened, stalked, strong-nerved: fls. small, mostly 

 white or yellow, sessile or nearly so, in a bracteate 

 terminal raceme or spike; sepals and petals free and 

 mostly similar, connivent or spreading; lip somewhat 

 spatulate, similar to petals; column short. Little cult.; 

 require conditions of warmhouse paphiopedilum. TV. 

 Lindleyi, Rolfe, has primrose-yellow decurved fls. 1 in. 

 long: 3-4 ft.: Ivs. many, 1-2 ft. long, oblanceolate, 

 membranaceous. B.M. 7368. N. Griffithii, Reichb. f., 

 has white deflexed pubescent fls. in a short spike; 16 

 in.: Ivs. 4-10 in. long, elliptic-lanceolate, acuminate.

NEVIUSIA (after Rev. R. D. Nevius, who discov- 

 ered it). Rosacex. SNOW WREATH. Ornamental shrub 

 sometimes planted for its white flowers. 



Deciduous: Ivs. alternate, petioled, doubly serrate, 

 stipulate: fls. perfect, in clusters or solitary; calyx-tube 

 flattish; sepals 5, petal-like, spreading, incisely serrate; 

 petals 0; stamens numerous, longer than the sepals, 

 persistent; carpels 1-A, styles slender, curved at the 

 apex, slightly shorter than the stamens: fr. consisting 

 of drupe-like achenes inclosed by the persistent calyx. 

 One species, found only in Ala. near Tuscaloosa and
