Lycopus LABIATAE Mosla 



pinnatifid sharply serrate or incised lvs. and small white or purple fls. in dense axillary 

 whorls; calyx with 4-5 nearly equal teeth; corolla almost equally 4-cleft; fertile stamens 

 2, on the lower side of the corolla tube; staminodes 2, on the upper side: nutlets smooth, 

 the top truncate. About 15 species, in north temperate regions; one in China. (From 

 the Greek terms meaning " a wolf " and " foot ", referring to the form of the lvs.) 



1. Lycopus lucidus Turcz. %JE^H (Ti Kua Erh Miao; Ground-melon Seedling) 

 (Mak.F.168). Erect stoloniferous herb, to 1.2 m.; fls. white, VIII-X; lvs. sharply 

 serrate. Eastern Asia; locally in Ki., Ku. Damp meadows. 



Lycopus europaeus Linn, has been listed from our area (F.H.E. 2: 282). This species is 

 described by Bentham as without stolons, " stolonibus nullis " (Benth. Lab. 186; DC. P. 12: 178). 

 It is named by Hooker from India (H.F. 4: 648j, but is described with " rootstock creeping or 

 stoloniferous". Kudo (p. 85) has reduced Miquel's L. europaeus from Japan to a variety of 

 L. lucidus. All the forms of Tsycopus known to the writer from China have stolons, and the 

 stolons, often bear tuberous rhizomes, as in Henry No. 4599 in the Gray Herbarium. 



15. Mosla Buch.-Ham. W%M (Chi Ning Shu; Green- vegetation Genus) 

 Branching aromatic annuals with slender stems, opposite lvs. and fls. in terminal 

 or axillary secund racemose 2-fld. whorls; calyx bell-shaped, enlarged in fr., gibbous 

 at the base; the throat hairy; corolla slightly 2-lipped: stamens 2, inserted on the upper 

 side of the corolla tube; staminodes 2, on the lower side; anther cells 2: nutlets globose. 

 About 10 species, in eastern Asia; most of them found in China. (The Nepalese name 

 of M. nepalensis.)
