DIVISION II. 
I. Narrow-leaved Pennyroyal. 
Pulegium angufii folium. 
The root is compofed of numerous fibres, long, 
flender» crooked, and whitiHi. 
The ftalk is firm, upright, not much branched, 
and a foot high. 
Tlie leaves are placed in pairs ; but they have 
ufually tLifcs of young ones in their bofoms : they 
are longifla, narrow, of a pale green, a little in- 
dented, and lliarp-pointed. 
The flowers grow in clufters at the joints; and 
they are fniall, and of a very faint bluilh, ofttn 
white. 
The feeds are fmall and blackifh. 
It is a native of the warmer parts of Europe, 
and flowers in June. 
C. Bauhine calls it Puhglum angufii folium. 
Others, Piikgium cervinum. Harts pennyroyal. 
Its virtues are the fame with the others.

WATER HOARHOUND. 
L r C O P V S. 
THE flower is made of a fingle petal which is tubular at the bottom, and divided into four 
parts at the edge, which form a kind of lips : the upper one confifls of a fingle fegment, which 
is broader than the others, and nipped at the end ; the other three fegments form the lower lip ; and 
of thefe the middle one is fmalier than the reft. The tubular part of the flower is of the fame 
length with the cup ; which is alfo formed of a fingle piece ; but it is divided into five fegments 
at the rim, which are narrow and lharp-pointed. The feeds are four ; and they ftand naked 
in the cup. 
Linnsus feparates this and feme others from the reft of the verticillate plants. They ftand among 
his didynamia ; this is one of his diandria monogynia ; the threads in the flower being only two, and 
the ftylefrom the rudiment of the fruit fingle. It is certain, that there are, as this author oblcrves, 
only two threads or filaments in the flower of lycopus^ and there are four in that of pennyroyal. But 
this is a flight mark of dilHndlion. The form and itrufture of the flower and of its cup, and the difpo- 
ficion of its feeds, agree with thofe of the other. This is a plain, familiar inftance of that author's 
unnatural arrangement of plants : thefe are both in every one's way to examine ; and from thefe I ap- 
peal to thofe who yet are inclined to own his fyftem, whether ■pennyroyal and water hoarhound do not 
evidently belong to the fame clafs, though he has feparated them into two very remote ones In his 
works. Every clafs affords many like inftances. 
DIVISION I. 
BRITISH SPECIES. 
Common Water Hoarhound. 
Lycopus vulgaris. 
The root is compofed of a multitude of long, 
white fibres, joined to a fmall head. 
The flalk is fquare, firm, upright, hollow, 
and two feet high : it is of a pale green, and is 
rarely branched. 
The leaves are placed in pairs ; and they have 
fhort footftalks : they are large, broad, oblong, 
and pointed at the ends : they are very fiiarply 
ferrated at the edges, and finuated deeply near 
the bafe ; and their colour is a flrong and lively 
green. 
The flowers are fmall and white : tiiey fland 
in chiflers round the ftalks at the joints, where 
the leaves fife. 
The feeds are fmall and brown. 
It is common by ditch-fides, and flowers in 
July. 
C. Bauhine calls it MarruHmn pahijtre giahrum. 
Others, Marrubium aqmticim. 
It is deftitute of tafte and fmell, and, fo far as 
we know, of virtue. 
DIVISION II. FOREIGN SPECIES. 
Narrow-leaved Virginian Lycopus. 
Lycopus Joins tenukis ferratis. 
The root is fibrous and fpreading. 
The llalks are numerous, fquare, upright, not 
much branched, and a foot or more in height. 
The leaves are placed in pairs, and are of a 
faint green : they are broad at the bafe, narrower 
to the point, and very elegantly ferrated at the 
edges. 
The flowers are finall and whitilh : the feeds 
are oblong and brown. 
It is frequent in the wet grounds in North 
America, and flowers in June. 
Gronovius calls it Lycopus foliis hnceolaiis u- 
mujjlms jerrciSis,
