 bract-lv.s. cream-white: fls. white or greenish.

NIEKEMBfiKGIA (for John E. Nieremberg [1590- 

 1503], a Spanish Jesuit and first professor of natural 

 history at Madrid). Holandcew. Cup-Flower. About 

 24 species of hardy perennial herbs from tropical and 

 subtropical America, allied to Petunia and characterized 

 by the long and very slender tube of the corolla. The 

 species in cultivation are valued chiefly for the open 

 border or for pot-plants, and are mostly of prostrate 

 habit, with showy fls. borne freely through the summer 

 and autumn. Stem decumbent or creeping, rarely sub- 

 erect, diffusely branched, the branches usually slender 

 and nearly glabrous : lvs. alternate, scattered, entire : 

 fls. borne singly on the tips of young shoots, mostly 

 white with a purple center ; calyx 5-parted, tubular or 

 bell-shaped ; sepals spreading ; tube of corolla long, 

 slender, attenuated below, abruptly expanded above into 

 a broad bell-shaped, saucer-shaped or funnel-shaped 

 limb, which has 5 broad, obtuse lobes. 



Several species of Nierembcrgia have distinct value 

 for certain purposes. JV. gracilis makes an excellent 

 pot or basket plant, and is also popular for the border. 

 ST. frutescens does finely in the open, but is more desir- 

 able as a pot-plant. If. rivularis is |i( rlKips the most 

 desirable species of the group, and is ;Miai>i<-d to a wide 

 range of conditions. It tlirives best in ;i moist soil with 

 a half-shaded exposure, but often makes tine patches on 

 a dry bank, or even iu the rockery. Both iV". gracilis 

 and iV. frutescens love a loose, rather moist soil, biit are 

 not impatient of dryness. These three species endure 

 winters without protection in the latitude of N. Y. 



Nierembergias are propagated chiefly by cuttings taken 

 in the fall, or by seeds. JV. rivularis is most readily 

 increased by dividing the creeping stem where it has 

 rooted at the nodes.

 rivuliris, Miers. WHiTE-Ctrp. Whole plant glabrous : 

 stem slen<ler, creeping, rooting freely at the nodes, form- 

 ing a dense mat, the branches seldom rising over (i in. 

 higli: lvs. oblong to oblong-spatulate, obtuse membra- 

 naceous, variable iu size, with a long, slender petiole: 

 fls. sessile or short-peduncled; calyx cylindrical, the 

 lobes oblong-lanceolate, slightly spreading: corolla-limb 

 broadly bell-shaped, 1-2 in. broad; throat golden yellow. 

 La Platte river, S. A. B.M. 5608. J.H. III. 31:.'!n. Gn. 

 23, p. 188; 25, p. 145. — A very adaptable and desirable 

 species for a stream bank, dry border or alpine garden. 

 The fls. are large and beautiful. It is difficult to eradi- 

 cate after once established, as small pieces of the stem 

 will take root and grow. 



BB. Fls. icJiile, with purple center. 



gracilis, Hook. Fig. 1490. Branches very slender, 

 ascending 0-8 in., slightly downy: lvs. scarcely ^'iin. 

 long, linear or slightly spatulate, those on the younger 

 branches somewhat hairy: limb of corolla spreading, 

 convex, white tinged and veined with purple towards 

 the center, throat yellow. Argentine Republic, S. A.

Vfeitchii, Berkeley. Stem 8-12 in. long, with slender, 

 glabrous or slightly pubescent branches : lvs. \^-\ in.

 lower broadly spatulate: calyx-lobes linear-oblong, re- 

 curved: corolla-tube K-?4 in. long, white, the limb 

 broadly bell-shaped. Trop. America. B.M. 5.599. F.

AA. Stem nearly erect. 



frutescens, Dur. Tall Cup-Plower. Stem 1-3 ft. 

 high, much l)ranched, shrubby: lvs. scattered, linear: 

 fls. about 1 in. broad, tlie limb saucer-shaped, white 

 tinted with lilac or blue; throat yellow; handsome. 

 Chile.— The fls. resemble N. gracilis in color, but are 

 much larger. Valuable iu the greenhouse or for the 

 border. As a pot-plant it makes a fine bush and bears 

 fls. almost continuouslv. It can be used as a bedding

 annuals with erect stems and finely divided alternate 

 lvs.: fis. showy, white, blue or yellow; sepals 5, regu-
