which it was not originally intended. In intermedia the 
stem is described as smooth ; not pubescent, as in the pre- 
sent ambigua, the leaves pubescent only at the edge and 
base; not so over both surfaces, especially the under, the 
bractes smooth; not pubescent on both sides, the leaflets 
of the calyx equal; not conspicuously unequal, the upper 
lip of the corolla obtusely bifid; not broad rounded and 
slightly emarginate, the middle segment of the lower lip 
obtuse and straight; not acute, and somewhat reflex at the 
top. The flower of intermedia is also much smaller than | 
in our plant, of a paler sulphur colour, and its calyx 
nearly twice as large. 
_ Ambigua is a hardy plant, and will grow almost any- 
where without care. Propagated by ‘seed and by parting 
the root. Blooms in July and August. Native of the more 
southern parts of Europe, especially of Germany, chiefly 
affecting mountainous situations. No mention is made of 
its possessing any portion of the medicinal qualities for 
which the closely allied purpurea is famed. |
