** Throat of the cal. naked. Inflorescence indeterminate, flowers in 
axillary distant whorls, none among the uppermost leaves ( or much 
shorter than they). 
■(■ Leaves stalked. 
6. M. satwa L. (Marsh whorled M.) ; leaves stalked ellip- 
tical ovate or ovato-lanceolate serrate, upper ones similar but 
smaller all longer than the distant dense whorls, calyx tubular 
with lanceolate acuminate teeth. M. arvensisvar. Benth. — a. 
whole plant more or less hairy, calyx and pedicels hairy. E. B. 
t. 448. — M. acutif'olia Sm. : E.B.t. 2415. — f3. whole plant 
nearly glabrous, pedicels and lower part of the calyx quite 
glabrous. M. rubra Sm. : E. B. t. 1413. 
Wet places, banks of rivers, and in hedges and thickets, . 7, 8. — 
The chief difference between this and the next is in the form of the 
calyx. The present is never, we believe, found in corn-fields, while 
genuine specimens of the other are almost confined to them or gardens ; 
but M. gentilis L. has the calyx and large upper leaves of M. arvensis, 
while it is almost glabrous like M. rubra Sm., and grows in wet 
places: Mr. Babington unites it to this species; Mr. Bentham to the 
next : it seems to connect the two. 
7. M. arvensis L. (Corn M.); leaves stalked ovate or ellip- 
tical sometimes cordate at the base serrate, upper ones similar 
and equally large all longer than the distant whorls, calyx 
campanulate, its teeth triangular acute about as broad as long. 
— a. hairy, leaves narrowed at the base, calyx clothed all over 
with spreading hairs. E. B. t. 2119. — d. hairy, leaves some- 
what cordate rugose, calyx clothed all over with spreading 
hairs. M. agrestis Sole : E. B. t. 2120. — y.? more glabrous, 
upper part of the calyx clothed with erect hairs, lower part and 
pedicels glabrous. M. gentilis L. : E. B. t. 2118. 
a. Corn-fields, common. — fl. corn-fields and neglected gardens ; 
Somersetshire; plentiful in Sussex. — 7 . watery places, rare; Holt 
in Norfolk ; Somersetshire; river-side above Warrington. N. Wales. 
21 . 8, 9. — The smell of the common variety has been compared to 
that of decayed cheese. 
'(■'(■ Leaves nearly sessile. 
8. M. * pratensis Sole (narrow-leaved M.) ; leaves nearly 
sessile ovato-lanceolate acute serrate, upper ones similar all 
longer than the distant subglobose whorls, calyx campanulate, 
lower part and pedicels glabrous, teeth triangular acute hairy. 
M. gentilis Sole : E. B. t. 449. M. gracilis Sm. 
Watery places in moist meadows (Sm). fl. 8, 9. — Stem and 
leaves usually glabrous. Leaves paler beneath and the calyx glandular. 
With this we - are not acquainted. Sole doubts if it be indigenous. 
Mr. Bentham remarks that it is intermediate between M. viridis and 
M. sativa var. 0., having the inflorescence of the present section and
