 prostritum, Lois. Gentian Blue Gromwell. Sub- 

 shrub: Iv.s. lanceolate-linear, margin somewhat revolute: 

 tube of corolla pubescent outside, densely villous at 

 apex. S. Eu. This is presumably the plant in the trade, 

 since L. prostratum, Buckl., is a white-fld. annual 

 pioperly called L. Matamorense. However, L. prostra- 

 liim, Lois., is referred by Index Kewensis to L. fruti- 

 fosioH, which see. Gn. 45, p. 135. J. H. III. 32:475. 

 BB. Habit erect: tube of corolla not hairy.

 (Inlle, and apparently more of a shrub, with the leaf 

 margins decidedly revolute. S. Eu.— Not cult.
