: 
S. germanica. 
Leaves (basal) ovate-oblong, 
acute, provided with dense 
white silky non-glandular 
pubescence (and thus grey- 
ish in appearance) more 
abundant on lower surface ; 
petioles similarly clothed. 
Upper leaves and bracts 
ovute- or linear-lanceolate, 
decidedly more densely 
silky than basal. 
All leaves thick in tex- 
ture. 
Flowers in whorls forming a 
dense terminal spike with 
a few separated whorls 
below. 
Calyx 10-11 
obeonic, teeth 
acuminate, usually rather 
shorter in proportion to 
calyx than those of alpina, 
Whole calyx (and teeth) 
clothed with long white 
ascending silky hairs, with 
sessile glands but no glan- 
dular hairs. 
min. long, 
triangular- 
Corolla pale purple or rose- 
pink; upper lip arched, 
c. $ as long as calyx, with 
long white silky hairs pro- 
jecting considerably beyond 
tip; lower lip slightly 
longer than upper, + entire 
or crenulate. 
Hairs in corolla - tube 
about halfway down. 
Stiyma white. 
Ripe seeds smooth, almost 
black (blackish brown), 
c. 2 mm. long. 
A HYBRID STACHYS. 
S. digenea. 
Leaves (basal) ovate-oblong, 
+ obtuse, green and hairy 
above, usually grey-green 
below with hairs and + 
silky pubescence and also 
sessile glands; petioles 
more silkily hairy than in 
alpina, 
bracts than in 
alpina and broader than in 
Upper leaves and 
narrower 
germanica, decidedly more 
silkily hairy than basal. 
Leaves slightly thick in 
texture. 
Flowers in whor!s laxer than 
those of germanica and 
closer near top of spike than 
those of alpina. 
Calyx 10-12 mm. long, ob- 
conie, teeth triangular- 
acuminate, as in germanica. 
Whole calyx (and teeth) 
clothed with long white 
ascending silky hairs, not 
quite so dense as in ger- 
manica, with sessile glands ; 
short glandular hairs pre- 
sent on calyx-teeth, rarely 
on tube. 
Corolla bright purple, paler 
near throat, larger than in 
germanica or alpina ; upper 
lip arched, c. $ as long as 
calyx, with long white 
hairs (not quite so dense 
as in germanica) projecting 
considerably beyond tip; 
lower lip considerably 
longer than upper, + entire 
or crenulate, broader than 
in germanica or alpina. 
Hairs in corolla- tube 
about ł way down. 
Stigma almost white, faintly 
tinged with purple. 
Ripe rather more 
coarsely rugulose than in 
alpina, brown, c. 23 mm. 
long. 
Only one seed usually 
fertile in each calyx.

S. alpina. 
Leaves (basal) ovate, obtuse, 
green, paler on underside, 
hairy above, rather less so 
beneath where there are 
sessile glands; petioles 
hairy. Upper leaves and 
bracts ovate-acute, only 
slightly more hairy than 
basal. 
Leaves thin in texture. 
Fiowers in whorls almost all 
separated, with a few aggre- 
gated ones at summit. 
Calyx 10-11 mm. long, cam- 
panulate, teeth broadly tri- 
angular (more abruptly 
pointed than in germanica) 
acuminate or mucronate, 
Whole calyx (and teeth) 
hairy with ascending- 
patent hairs, mixed with 
shorter glandular ones ; 
sessile glands also present. 
Corolla dull brownish-purple ; 
upper lip flat, c. } as long 
as calyx, with dense hairs, 
shorter than those of ger- 
manica, projecting beyond 
tip slower lip considerably 
longer than upper, + emar- 
ginate. 
Hairs in corolla-tube near 
the base. 
Stigma purplish. 
Ripe seeds usually minutely 
and irregularly rugulose, 
brown, c. 2? mm. long.
