rcnco fonns a fliittcmd |)\ nuiiiil. Comlla ^ iiioli lonp:, dull rose, rarely 

 wliito, with the riii^' of liairs more conspicuous than in any of the 

 previous species, and the lateral lohes of the lower lip with a subulate 

 tooth, which is rarely absent. Nucules similar to those of L. incisum. 

 I*l:int preen, frequently tinned with purple, thinly hairy, with the stem 

 subirlabrous, as in the preceding forms. 



The common form of this [)lant is readily distinguisliablc from 

 L. incisum by its faintly crenate bnicts, not at all wedpe-shaped at 

 the base, but the var. decipiens is very likely to l)e mistaken for it. 

 The corolla, however, is much longer, and with a distinct internal ring 

 of hairs in the variety as well .as in tiie typical plant. This ring is 

 merely rudimentary in L. incisum. 



It is (piite possible that L. iiitermedium, incisum, and purpureum 

 ought to be considered merely as sub-species, but I have not put them 

 in this form, because L. intermedium appears to have forms which, at 

 least as dried specimens, are scarcely distinguishal)le from L. amplexi- 

 caule, and to consider L. amplexicaule and L. purj)ureum as constitu- 

 ting extreme forms of a single super-species is impossible without 

 distiu'bing idl existing ideas of a species even as understood by 

 the class of botanists who use the term in its most comprehensive 

 sense.

Perennial. Rootstock passing insensibly into the stem. Barren 

 shoots short, erect. Stems much branched, a large po:-tion at the 

 base decumbent and rooting; the flowering part ascending or erect. 

 Leaves stalked, ovate or deltoid-ovate, cordate, slightly acuminate, 

 acute or subacute, irregularly crenate-serrate or crenate. Verticil- 

 lasters (or at least the lower ones) remote from each other. Bracts 

 all quite similar to the leaves, but the uppermost ones subsessile, 

 smaller, narrower, and more acuminate. Calyx sparingly hairy 

 or nearly glabrous; teeth triangulate-subnlate, spreading, sparingly 

 ciliated, scarcely longer than the tube; tube slightly curved down- 

 wards, oblique at the mouth. Corolla tube much longer than the 

 calyx-teeth, with a very conspicuous transverse ring of hairs within,
