drical spike, six inches high, formed of a dense mass of 

 sessile, or nearly sessile, spreading flowers, each subtended 

 by an oblong, leaf-like, small bractea, equal in length to 

 the flower. Calyx deeply cut into five, oblong, acute 

 segments, little more than half the length of the flower. 

 Corolla campanulate, cleft one-third of the way down, into 

 five ovate, acute, nearly erect segments. . Stamens ten, 

 arising from the base of the corolla, equal in length, 

 included, five opposite to, and five alternate with, the 

 segments of the corolla. Pistils five. Germens erect, 

 ovate, united at the base into a short stipes, each is termi- 

 nated above by a rather short, subulate style. Stigma a 

 mere point.
