branches opposite and axillary, simple. Leaves opposite, 
pubescent, ovato-acuminate, coarsely serrated, tapering at 
the base gradually into a footstalk, nearly equal to the leaf 
in length. The leaves at the extremity of the branches 
appear suddenly to become ovato-lanceolate, lax, sessile 
bracteas, enclosing one to three flowers. Calyx of five 
deep, linear-lanceolate, ciliated segments, not half so long 
as the tube of the corolla. Corolla hypocrateriform. Tube 
curved, white, purplish upwards, where it is somewhat in- 
flated. Limb very bright blue, of five nearly equal, emar- 
ginate lobes. Stamens four; two with hairy filaments, the 
other two small, and apparently abortive, all included. 
Germen oblong, tapering into a slender Style, included 
within the flower: Stigma of two, very unequal, sharp- 
pointed lobes. |
