 numerous. The cah-x teeth spread less than in B.

B. Americana, Linn., is considered by some a separate 

 species from the above, but in Germany, where most seeds of 

 annual flowers are grown, it is used by Siebert and Voss (in 

 Vilmorin's Blumengartnerei) to include B. demissa. Ji. elata, 

 and other forms.— i?. Jdmesonii, Benth. = Streptosolen .Tame-

 variegated lvs. is rarely found wild.

BRUNFfiLSIA (Otto Brunfels, physician and botanist 

 .if the Kith century). Syn., Franciscea. Solandcece. 

 Slore than 20 trees and shrubs of tropical America, a few 

 of which are grown in warm glasshouses. Lvs. entire, 

 oblong, often shining : fls. in terminal cymes or clus- 

 ters, or solitary, large and showy, fragrant ; corolla 

 with 5 rounded and nearly equal spreading lobes (or two 

 of them a little more united) ; stamens 4, in the throat 

 of the corolla, the anthers all alike : fr. berry-like. 

 Brunfelsias are usually winter-flowering plants. The 

 wood must be well ripened before flowering begins. 

 Grow in a rather sandy compost. Of easy culture. Re- 

 quire a night temperature of 50°. They bloom best when 

 pot-bound. Prop, by cuttings from the new growth in 

 spring. 



Hopeina, Benth. {Franciscea Bopedna, Kook. F.uni-
