 green and some other ornamental low aromatic plants 

 with alternate, evergreen lvs., white, pink or scarlet, 

 often fragrant fls. in terminal or axillary racemes or 

 solitary, and with decorative, berry-like red or blackish 

 fr. G. procumbens is fully hardy North, while the other 

 N. American species need protection during the winter; 

 they are well adapted for borders of evergreen shrub- 

 beries as well as for rockeries, and in suitable soil they 

 are apt to form a handsome evergreen ground-cover. 

 Most of the foreign species can be grown only South or 

 as greenhouse shrubs. Some have edible fruits, and an 

 aromatic oil used in perfumery and medicine is ob- 

 tained from G. procumbens and several Asiatic species. 

 They grow best in sandy or peaty, somewhat moist soil 

 and partly shaded situations. Prop, by seeds, layers or 

 suckers, division of older plants, and also by cuttings of 

 half-ripened wood under glass. About 90 species in the 

 warmer and subtropical regions of Asia, Australia, and 

 in America from Canada to Chile. Erect or procumbent 

 shrubs, rarely small trees, usually hairy and glandular: 

 lvs. petioled, roundish to lanceolate, mostly serrate : 

 fls. in terminal panicles or axillary racemes or solitary; 

 calyx 5-parted; corolla urceolate, 5-lobed; stamens 10: 

 ovary superior: fr. a 5-celled, dehiscent capsule, usually 

 enclosed by the fleshy and berry-like calyx.

 ding; corolla ovate, white, about Ji in. long: fr. scarlet.

GAtTRA (Greek, superb). Onagr&cem. This includes 

 several herbs which are distinct in appearance, but 

 scarcely possess general garden value, though they are 

 pleasant incidents in the hardy border of those who like 

 native plants. The bloom ascends the slender racemes 

 too slowly to make the plants as showy as possible. The 

 best kind is G. Lindheimeri, which has white fls. of 

 singular appearance, with rosy calyx tubes. Gaura is a 

 genus of 20-25 species of annual and perennial herbs 

 confined to the warmer regions of N. Amer. : lvs. alter- 

 nate, sessile or stalked, entire, dentate, or sinuate: fls. 

 white or rose, in spikes or racemes; calyx tube decidu- 

 ous, obconical, much prolonged beyond the ovary, with 

 4 reflexed lobes; petals clawed; stamens mostly 8, with 

 a small scale-like appendage before the base of each 

 filament; stigma 4-lobed, surrounded by a ring or cup- 

 like border: fr. nut-like, 3-1-ribbed, finally 1-celled, and 

 1— 4-seeded. Gauras are easily prop, by seed. They pre- 

 fer light soils, and the seedlings can be transplanted 

 directly into permanent quarters.
