 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. diarn. tomentose, calyx-teeth very short trian-

DECCAN PENINSULA, Eeyne, Wight ; Bababoodan Hills and Copper Mts., Belhiry, 

 Laiv, Stocks. 



Stem erect. 8-12 in., from a large woody rootstock, terete. Leaves 1-1 ^ by 

 ^-\ in., thick, silkily pubescent on both surfaces. Spikes very slender, shortly peduncled, 

 flexuous. Calyx ^ 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. rugrosa, Hook. /. ; 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. II. c. in part. Mentha rugosa, Herb. Heyne. 



UECCAN PENINSULA ; Mountains of Tinnevelly, Beddome ; at Pallamcotta, 

 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 shorcer 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 

 himself. 



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.

Stem 1-2 ft., much branched ; branches slender, erect, woody. Leaves 1-3^ in., 

 rather membranous. Spikes i- 1 in. diam., on slender peduncles; whorls confluent. 

 Calyx in fruit 7 ' 2 in., with erect teeth. Corolla-tube exserted, lobes sparsely hairy. 

 Outlets ellipsoid, obtusely 3-gonous, shining. 



4. D. auricularia, Blume Bijd. 826; annual, hirsute or villous, 

 leaves sessile or shortly petioled oblong serrate, spikes 2-3 in. villous, calyx- 

 teeth triangular incurved in fruit. Benth. Lab. 158, in Wall. PI. As. Rar.
