1. D. myosuroides, Benth. in Wall. Pl. As. Rar. i. 30, Lab. 157, and 
in DC. Prodr. xii. 156 (all in part); perennial, erect, silkily tomentose, 
branches woody, leaves subsessile linear-oblong obtuse denticulate, spikes 
very slender 3-5 in. by } in. diam. tomentose, calyx-teeth very short trian- 
gular. Wall. Cat. 1547; Dalz. & Gibs. Bomb. Fl. 208. Mentha myosu-

Stem erect, 8-12 in., from a large woody rootstock, terete. Leaves 1-1} by 
1-3 in., thick, silkily pubescent on both surfaces. Spikes very slender, shortly peduncled, 
flexuous. Calyx Ñ in., densely tomentose, fruiting hardly enlarged, teeth erect in 
fruit. Corolla minute, glabrous ; tube included. Nutlets ellipsoid, compressed, granu- 
late. —Bentham's var. bracteata is founded on a young spike with the bracts protruded. 
2. D. rugosa, Hook. f.; perennial, erect, appressed, fulvous-woolly, 
branches woody, leaves subsessile linear-oblong obtuse subentire, spikes 
slender 2 in. by } in. diam. tomentose, calyx-teeth very short triangular. 
D. myosuroides, Benth. ll. c. in part. Mentha rugosa, Herb. Heyne.

Heyne. . 
Very closely allied to D. myosuroides, and confounded with it by Wallich and 
Bentham ; of the same size and habit, but not at all silky ; form of leaves the same, 
but nerves more spreading, spikes much shorter and thicker.—Heyne seems to have 
distinguished the two from the names quoted by Wallich, of which that of M. rugosa 
is attached to a specimen in Rottler’s Herbarium, no doubt collected by Heyne 
imself. 
3. D. salicifolia, Dalz. mss.; stem and young leaves appressedly 
pubescent or silky, leaves sessile or petioled linear-lanceolate subentire or 
remotely serrate, spikes slender 2—4 in. villous, calyx villous short, teeth 
triangular almost equalling the tube. Dysophylla sp. 3, Herb. Ind. Or.
