 Mag., Tokyo, XXVI. (1912), p. 298, nomen. 



Labiatas, Stachydeas. 



Calyx turbinately tubuloso-campanulate, 5-toothed, 5-cos- 

 tate and with 5 accessory intermediate nerves, equal ; teeth 

 equal, subulate, herbaceous, not rigid. Corolla-tube much ex- 

 serted upon the calyx, elongato-cylindrical, with an interrupted 

 pilose annulus within, gradually enlarged towards the throat ; 

 limb bilabiate ; posterior lip erect, obovate, entire or sometimes 

 emarginate, concave, subgaleate, pubescent dorsally ; anterior 

 lip 3-fid, horizontal and patent ; midlobe larger, rotund ; lateral 

 lobes shortly ovate. Stamens 4, didynamous, longer in the an- 

 terior 2, close to front of the galea, exserted upon the corolla- 

 tube ; anthers approximate, 2-celled ; anther-cells distinctly 

 and vertically divergent, glabrous. Disc equal, short. Style 

 2-fid into subulate arms at the apex, the upper arm slightly 

 shorter. Nutlets usually acutangularly triquetrous, smooth, 

 truncate with subacutangular margin at the apex. 



Dwarf erect perennial herb, stoloniferous; stolons hypogasous. 

 Leaves large, opposite, petiolate, but sessile in the superior ones, 

 approximate, coarsely dentate with obtuse teeth, undivided, 

 penninerved, rugose. Verticillasters 1— 3-flowered, axillary, ap- 

 proximate ; bracteoles linear. Flowers sessile or nearly so, small, 

 purpurascent. 



This genus comes near to Stachys, Loxocalyx, Leonurus and 

 Lamium, and may be placed next to Matsumurella to which 

 it is very closely allied. It differs from Stachys by having 

 truncate (Maximowicz wrongly described and figured it as 

 " vertice rotundato.") nutlets, from Leonurus by its divergent 

 anther-cells and non-spinous calyx-teeth, from Loxocalyx by 

 not having the distinctly obliquely bilabiate calyx, and from 

 Lamium by having stolons and glabrous anthers.
