* The species is extremely variable, and many forms have received specific 

 names ; but they are so closely connected by the intermediates in the large series 

 now before me, and they are so devoid of any geographical significance, that 

 it appears most reasonable to treat the whole as unispecific. The constant 

 characters are the raceme or panicle of small blue flowers, cylindric calyx, pro- 

 truded corolla tube, upper straight concave lip, and reflexed 3-lobed lower one. 

 The degree of protrusion of the tube and the stamens is certainly in some cases 

 sexual. The leaves vary through a very wide range ; they are even occasionally 

 digitate or pedate through the division of the lower leaflets of a trifolinlnte leaf 

 [Morse, 4). Hemsley's var. erythrophylla has the upper lip shorter and the 

 , stamens protruded from earliest anthesis, but the intermediates are numerous.
