LIN. SYST. Didynamia, Gymnospermia. Calyx 5-nerved, 

 turbinate, nearly equal, with a truncate mouth, and 5 teeth, 

 which are subulate, and rather spiny at apex, and at length 

 spreading. Corolla with an inclosed, rarely exserted tube, 

 which is naked, or obliquely annulate inside, and a bilabiate 

 limb : superior lip oblong, quite entire, sometimes flattish, with 

 a narrowed base, and sometimes arched : lower lip spreading, 

 trifid, the lateral lobes oblong, and the middle lobe obcordate. 

 Stamens 4, ascending, didynamous : lower 2 the longest ; an- 

 thers approximate by pairs, 2-celled : cells parallel, transverse, 

 rarely diverging, with naked valvules. Style about equally 

 bifid at top ; lobes subulate, rarely short, and obtuse, stigmati- 

 ferous at top. Achenia dry, smooth, triquetrous, truncate at 

 apex, with acute angles. Erect herbs. Leaves generally deeply 

 lobed : lower ones roundish : floral ones narrower, all exceeding 

 the flowers much. Whorls dense, axillary, distinct. Bracteas

SECT. I. CARDI'ACA (the Latin name of motherwort, from 

 cardia, the heart ; in allusion to its supposed efficacy in the cure 

 of cardialgia.) Benth. lab. p. 518. Cardiaca, Mcench, meth. p. 

 401. Tube of corolla obliquely annulate inside, rather ventri- 

 cose above the ring ; upper lip flattish, narrowed at the base : 

 lower lip spreading, with the middle lobe entire. 



1 L. PUBE'SCENS (Benth. in Wall. pi. asiat. rar. 1. p. 63. lab. 

 p. 518.) finely pubescent; leaves all ovate, acuminated, rather 

 deeply toothed ; corolla about 3 times as long as the calyx. If . 

 or $ . H. Native of the mountains of Kamaon, Wall. ; Choor 

 and Kanaour, Royle. Leaves more toothed than lobed. Whorls 

 20-30-flowered, remote. Corollas larger than those of L. Car- 

 diaca.

2 L. ROYLEA'NUS (Benth. 1. c.) stem erect, finely tomentose ; 

 leaves ovate, acuminated, deeply serrated, or 3-5-lobed, villous 

 above, and clothed with hoary tomentum beneath, as well as the 

 calyxes. 3 . or $ . H. Native of Mount Choor, Royle. 

 Stem branched, with pilose axils. Whorls many-flowered : 

 lower ones remote : upper ones spicate.

3 L. CARDI'ACA (Lin. spec. p. 817.) pubescent ; lower cauline 

 leaves palmatifid : superior leaves ovate, lobate : floral leaves 

 oblong, subtrifid, narrowed a long way at the base : lobes all 

 ovate or lanceolate ; calyxes glabrous or villous. JJ . or $ . 

 H, Native throughout Europe and Middle Asia, on banks or 

 under hedges, in a gravelly or calcareous soil. In several places 

 both in Scotland and England, in like situations. Smith, engl.

 Mor. hist. sect. 11. t. 9. f. 18. Stems branched at the base. 

 Whorls 6-15-flowered, distant. Corolla villous outside, pale 

 red or white, and striped with purple veins. The herb is bitter 

 and tonic, with no very pleasant, but pungent smell. It was 

 formerly used in Cardialgia, whence its old name ; but it has 

 now become wholly obsolete, except, perhaps, among cow- 

 leeches and farriers. Bees are fond of the flowers. In Ger- 

 man, Motherwort is called Herzgeshaun or Herzkraut. In 

 Swedish, Bonassla. In French, Agripaine, Cardiaque, La Cor- 

 diale. In Italian, Spanish, and Portuguese, Agripalma, Car- 

 diaca, &c. 



Var. /3, villosus (Benth. lab. p. 518.) leaves more wrinkled, 

 and are, as well as the stems, villous ; calyxes rather villous.
