NIEREMBERGIA (named after 

 John Ensebius Nieremberg, 1595-1658, 

 a Spanish Jesuit, author of a work 

 on the Marvels of Nature). ORD. 

 SolanacecB. A genus comprising about 

 a score species of mostly half-hardy, 

 elegant, perennial herbs, creeping, dif- 

 fuse, or rarely almost erect, often slen- 

 der and glabrous ; they are natives 

 of extra- and sub-tropical America. 

 Flowers pale violet or whitish, on 

 solitary pedicels ; limb of corolla often 

 elegantly expanding; tube slender, 

 elongated. Leaves entire. The hardy 

 species prefer a light but not very 

 dry soil, and are all easily increased 

 by cuttings, placed in a gentle 

 heat. The species best adapted for 

 growing in cool houses are of com- 

 paratively easy culture. They thrive 

 best in a compost of three parts good 

 sandy loam, and one of thoroughly 

 decomposed manure and sharp sand. 

 These kinds should be propagated, 

 during August, by cuttings, which, 

 when well rooted, should be potted off 

 singly and placed for the winter on a 

 light, airy shelf in the greenhouse; 

 only enough water being given to pre- 

 vent flagging. In February or March, 

 shift into Sin. pots, in which the 

 plants may be allowed to flower,' or 

 they may be transferred afterwards 

 to beds or vases outside. Propagated 

 also by seeds, which should be sown 

 in a warm greenhouse during spring 

 or in autumn, and the plants grown 

 on in the way recommended above for 

 cuttings. The undermentioned species 

 are those best knowu to cultivation. 

 N. calyclna (large-calyxed).* fl. yellow 

 at the base, with a yellowish tube and 

 a white limb; peduncles lateral, one- 

 flowered, short. September. I. opposite 

 and alternate, roundish-obovate, petiolate. 

 Stems procumbent. Buenos Ayres, 1834. 



Plant clothed with glandular pubescence. Half-hardy. (B. M. 

 3371 ; S. B. F. G. ser. ii. 319.) 



N. nlicanlis (thread-stemmed).* /. usually lilac, with a yellow 

 centre ; tube slender, glandular ; peduncles opposite the leaves, 

 one-flowered. May. I. linear-lanceolate, acute or obtuse. A. 6in. 

 to 12in. Buenos Ayres, 1832. Plant glabrous, erect, filiform. 

 Greenhouse. (B. M. 3370 ; S. B. F. G. ser. ii. 243.) 



N. frutescens (shrubby).* fl. delicate blue, shaded to white at 

 the edges, about lin. iu diameter, densely produced on much- 

 branched flax-like stems. Early summer. I. linear, liin. to 2in. 

 long. A. 1ft. to lift. Chili, 1867. A handsome hardy species, 

 with a shrubby habit.

 long. Summer. I. linear, sub-spathulate, obtuse. Stems
