 24 species of hardy perei 

 subtropical America, allie. 

 bv the long and very sU'iid.-i- tub,- of tlie corolla, iiie 

 species in cultivation are valued cl,i,-tly 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, difl'usely 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 fuunel-shaped 

 limb, which has 5 broad, obtuse lobes. 



Several species of Niererabergia have distinct value 

 for certain purposes. xV. gracilis makes an excellent 

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

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

 able as a pot-plant. iV". rivitlaris is perhaps the most 

 desirable species of the group, and is adapted to a wide 

 range of conditions. It thrives best in a moist soil with 

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

 a dry bank, or even in the rockery. Both JV. gracilis 

 and N. frutescens love a loose, rather moist soil, but 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 bv seeds. N. rivularis is most readily 

 increased by dividing the creeping stem where it has 

 rooted at the nodes. 

 A. Stem prostrate or creeping : branches ascending. 

 B Fls. creamy white, sometimes slightly tinted with
