 plant mostly pubescent (at least the foliage), and varil

 10. hjbrida, Hort. The hybrid 

 Lobelias are mostly of French ori- 

 gin, and they are little known in 

 the Amer. trade, although they are 

 occasionally imported by amateurs. 

 It is doubtful if they will endure 

 the winters of the northern states, 

 although they make excellent pot 

 subjects for blooming in the sum- 

 mer border. They may also be 

 planted in the open and lifted on 

 the approach of winter: or new stock 

 can be raised from divisions of 

 the old plants, or from offsets, or from seeds. Many of 

 these hybrids are most showy, and they should be bet-

11. Gerirdi, Hort. Tlahitot Z. fulgens or L.cardinalis: 

 Ivs. lanceolate or lance-oblong, glabrous, denticulate: 

 fls. in a heavy terminal spike or raceme, rich violet, 

 lA in. or more long. Obtained by Chabanne and Gou- 

 jon of the Botanic Garden of Lvons, and introduced to 

 the trade in 1895 by Rivoire PJre et Fils, Lyons. The 

 hispid calyx suggests £. «,/p;i»i7Jca. R.B.22, p ll' 

 I.H. 42, p. 2G8.- It varies into rose-color (var. Lugdu- 

 nSnsis) and into coral-red, violet-purple, and the like. 

 Ihe pistillate parent was a form of Z. syphilitica and 

 t^lie stammate parent was the "Queen Victoria" form of 

 Jy. fulgens. The plant was named for M. Gerard, direc- 

 tor of the botanical collection at Lyons.

13. Iaxifl6ra, HBK. (L. Cnvanlllesii, Mart. Sypho- 

 cdmpylus bicolor, Don). Tall, branching herb or sub- 

 shrub, with thinly hairy stems: Ivs. lanceolate or ovate- 

 lanceolate, acuminate, sharp-denticulate: fls. nodding, 

 on long, axillary pedicels, IJ^in. long, cylindrical, the 

 stamens projecting from the side, red and yellow, pu- 

 bescent. Mex. B.M. 3G0O. G.C. III. 1:585. -An old 

 plant requiring cool greenhouse culture, or thriving in 

 the open in pots. It may also be planted out like i. 

 fulgens.
