[ Thymus. 
the nearly sessile leaves of M. viridis ; in his Handbook he inad- 
vertently refers E. B. t. 449 to M. arvensis. 
*** Throat of the calyx closed with hairs. Flowers in axillary distant 
whorls, none among the uppermost leaves. 
9. M. Pulegium L. ( Penny-royal ) ; flowers tvhorled, leaves 
ovate downy obtuse subcrenate, stem prostrate, flower-stalks 
slightly and calyx very pubescent, teeth of the latter fringed. 
E. B. t. 1026. 
Wet commons and margins of brooks ; England and S. of Ireland. 
Rare in Scotland and scarcely indigenous. It. 8, 9. — The smallest 
of the genus, readily known by its prostrate stems, and small, fre- 
quently recurved leaves, both of which are thickly covered with short 
hairs, and especially by the hairy throat of the calyx. Smell powerful. 
Much used medicinally. 
Tribe II. Satureine/e. Corolla two-lipped , the lube about as 
long as the calyx; lips nearly equal in length , upper one nearly 
plane. Stum, diverging, nearly equal, protruded. (Gen. 4, 5.) 
4. Thymus Linn. Thyme. 
Flowers whorled or capitate. Cal. with 10 — 13 ribs, tubular, 
2-lipped ; upper lip 3-toothed, lower one bifid ; the throat hairy. 
Cor. with the upper lip erect, nearly plane; lower patent and 
trifid. Stamens diverging. Anther-cells at first nearly paral- 
lel, afterwards diverging; connectivum subtriangular. — Name: 
SvpoQ, the heart; from its balsamic odour strengthening the 
animal spirits. 
1. T. Serpyllum L. (wild 7’.) ; flowers whorled and capitate, 
stems branched decumbent, leaves plane oblong or ovate obtuse 
entire petiolute more or less ciliate at the base, floral leaves 
similar, teeth of the upper lip of the calyx ovato-lanceolate of 
the lower subulate ciliate, upper lip of the corolla notched 
more or less ovate. E.B. t. 1314. — a. stems prostrate creeping, 
flowering shoots ascending, upper lip of the cor. oblong. — ,d. 
stems and flowering shoots diffuse ascending, upper lip of the 
cor. semicircular. T. Chamaedrys Fries. 
Hills and dry pastures, abundant. If.. 6 — 8. — Variable in size, 
and in the hairiness and scent of its foliage, which is sometimes all 
over hoary, and smells like lemon. Flowers purple. Mr. Bentham, 
the best authority for what is a species among the Labiatte, unites 
T. Chamaedrys of Fries to T. Serpyllum, characterizing it as a variety 
by the larger and less rigid leaves. Mr. Babington separates it on 
account of its having a different habit: — the above characters of our 
varieties are intended to indicate the chief specific differences upon 
which he rests; he adds that in 1\ Serpyllum the achenes are “globose.
