extent except with moist^^re, coolness and a fairly rich 

 soil. The plant forces well and easily in a coolhouse for 

 early spring flowering. It is tenacious of life and gen- 

 erally easy to manage.

 or triangular, 3-5-lobed, the lobes crenate-toothed; steni- 

 Ivs. usually only 1, rarely 2-3: panicle loose; petals 

 small. W. Amer. — The lobing of the Ivs., according to 

 Bot. of ('alif., varies so that it may pass into the next 

 species.

 round at the base, short-petioled, densely setose above, 

 villous beneath, not foveolate, 5-nerved or 3-nervod : 

 bracts broadly suborbicular, somewhat rounded at the

Var. floribunda is more suited to pot culture in pots 

 and flowers more freely when sniail than the type. 

 L'tsidndra, or Pleroma spl^ndexs, Hort., should be 

 compared with this. T. scniUIecandra is a plant of easy 

 culture that has been highly praised by several con- 

 imisseurs. Cuttings struck in April will ;,nvo bushy 

 plants for fall and winter blooming. Handsome speci- 

 mens may be had by keeping the" same plant two or 

 three years, training it to wires or stakes in a cool- 

 house where it has plenty of root room. The flowers 



last but a day or so, but new ones open up every day 

 and the flowering season lasts for several weeks. 

 Plants may also be used for summer bedding. They are 

 seldom out of bloom. The species is much esteemed in 

 Florida, where it makes a showy shrub 8 ft. liigh. It 

 endures a few degrees of frost with impunity, and even 

 if cut down it sprouts readily. 



61egans, Cogn. (PJerdma Uegans, Gardn.) Tender 

 shrub, 3-6 ft. high: lvs. rigid, fragile, oblong or ovute- 

 oblong, 3-nerved: fls. purple, 1>2 in. across; calyx mare 

 or less armed with rigid spreading bristles which are 

 thickened at the base. "Brazil. B.M. 4202. P.M. 15:27.

TIEDEMANNIA rigida, Coult. & Rose, is a hardy 



native, white-flowered swamp herb, growing 2-5 ft. 

 high from clustered tubers. It has pinnate lvs. with 3-9 

 leaflets. This was ofliered in 1890-91 by a collector of 

 North Carolina plants, but is probably not in culti- 

 vation. For a fuller account, see Coulter and Rose's
