Stems decumbent, numerous, radiating from the root- 
stock, square above, rounded below, clothed with many 
short hairs, which are closely appressed in the upper part 
and pointing downwards, those in the lower part more 
spreading, but still much reflexed ; spikes slightly inclined, 
just raised above the ground, compressed-globose, the ver- 
ticils many-flowered, never distant; calyx covered with 
straight hairs, the sepals ending in stiff points; corolla 
three times longer than the calyx, the exterior covered 
with scattered shaggy hairs, which are long and silky at 
the base of the tube, but becoming shorter and more scat- 
tered as they approach the lip; opening of the mouth very 
wide, lower lip crenate, wavy ; lower leaves on long stalks, 
cordate at the base, oblong, regularly crenate, glandular on 
the under surface, with short scattered hairs, upper leaves 
lanceolate on short stalks. 
Specimens of B. hirta, Reich., have not come under my 
notice, nor have I been able to meet with Reichenbach’s 
diagnosis; but the form described above seems to agree 
very nearly with Professor Boreau’s description of that 
plant, which is here appended for the sake of comparison : 
“ Stem clothed with many short stiff hairs ; leaves with 
soft long hairs, very distinctly crenate ; spike short, inters 
rupted ; calyx softly hairy at the summit ; low&r lip of the 
corolla rounded crenate.’' ( Flore, &c., loc. cit.) Mr. Bentham 
in his Labiatarum genera et species, p. 532, gives, amongst 
the synonyms of his Stachys Betonica, “ Betonica hirta, 
Leyss., Reichb., Icon., Bot. Eur. 8, 4, t. 711,” which may be 
identical with B. hirta, Reich. ; but the only reference to 
it which I have met with is in Dr. Garke’s Flora von Nord- 
nnd-Mittel Deutschland, where it is shortly described as 
“ Yar. a, hirta, Leyss. — Stem with short hairs, calyx rough- 
haired.” (Ed. vi., p. 318.) 
The Cornish form is very plentiful on the cliffs of “ Killas” 
rock, lying between Caerthilian and the Lizard Lights, grow-
