3. S. clandestina L. ( ' small- flowered S.) ; leaves ovate-oblong 
incise-toothed or pinnatifid, lower ones stalked, upper oblong 
acute sessile scarcely cordate or amplexicaul, bracteas cordate- 
ovate acuminate slightly shorter than the calyx, tube of the 
corolla longer than the calyx. S. obtusata Link. S. prascox 
Savi. 
Dry gravelly banks, rare. Lizard Point, Cornwall. Jersey. V- ■ 
7. — This is a very variable plant, but usually with deeply toothed or 
pinnatifid leaves, and appears to be the southern form or represent- 
ative of S. Verbenaca, to which also several other supposed species 
may be conveniently referred. 
B. Stamens 4. (Gen. 3 — 20.) 
Tribe I. Menthoideas. Tube of the cor. scarcely longer than 
the cal., its limb 4 — 5 cleft , nearly regular. Stam. diverging 
upwards. (Gen. 3.) 
3. Mentha Linn. Mint. 
Cal. equal, 5-toothed ; its mouth naked or rarely villous. Cor. 
nearly regular, 4-cleft ; its tube very short. Stum, diverging, 
exserted or included. Anther-cells parallel. — Name : or 
pivtiq, an ancient Greek term for these plants. 
* Throat o f the cal. naked. Inflorescence terminating the stems. Upper 
or ull the whorls approximated into spikes or in terminal heads. 
f Leaves sessile or the lower ones only stalked. 
1. M. sylvestris L. ( Horse M.) ; leaves subsessile ovate ellip- 
tical or lanceolate sometimes subeordate at the base serrate, 
downy hoary beneath, spikes almost cylindrical scarcely inter- 
rupted, bracteas subulate, calyx very hairy, its teeth acumi- 
nate. — a. leaves lanceolate. E. B. t. 686. — 0. leaves elliptical. 
M. rotundifolia Sole. 
Moist waste ground : not uncommon in England. Sidlaw Hills, 
Forfarshire. Ireland, y. 8,9. — Partial bracteas sometimes much 
longer than the flowers, and far more conspicuous than in the figure 
in E. B. There is a variety with somewhat wrinkled and crisped 
leaves, which passes into our y8. : it however can scarcely be M. crispa 
E. B. S. t. 2785, which seems, from the figure, more allied to M. 
aquatica. 
2. M. rotundifolia L. (round-leaved M.) ; leaves sessile ellip- 
tical obtuse sharply serrate wrinkled downy shaggy beneath, 
spikes interrupted, bracteas lanceolate, calyx somewhat hairy, 
its teeth short and acute. E. B. t. 446. 
Moist places, in waste ground ; not unfrequent in many parts of 
England. Anglesea. Near Auchindenny, Scotland; but scarcely 
wild. Near Cove, Ireland, y . 8, 9. 
3. M. * viridis L. (Spear M.) ; leaves lanceolate acute gla-
