TROPICAL and TEMPERATE HIMALAYA and N. BENGAL PLAINS ; from Kashmir 

 to Bhotan, alt. 1-6000 ft. KHASIA MTS., alt. 0-5000 ft. CHITTAGONG, J. D. H. $" 

 T. T. DISTKIB. Burma, China. 



A very strong-scented strict erect herb, 1-3 ft. Leaves 1-1 \ in. ; petiole - in. 

 Racemes very slender, terminating the branches, lax-fld. Corolla % in. long, white 

 or purplish, tube short. Fruiting calyx in., hemispherical. Nutlets as in Perilla. 

 The other described species are all extremely near M. dianthera, and perhaps forms 

 of it. 



18. 1KENTHA, Linn. 



Strong-scented perennial herbs, rootstock creeping. Whorls many-fld., 

 in axillary and terminal spikes, bracts various ; flowers small. Calyx, cam- 

 panulate or tubular, 5-toothed, throat naked or villons. Corolla subequally 

 4-lobed. Stamens 4, equal, erect, distant ; anther-cells parallel. Style-arms 

 short. Nutlets smooth or reticulate. Species about 25, N. temp, regions, 

 introduced in many countries. 



Mentha viridis, L. (spear-mint), M. piperita, L. (peppermint), M. sativa, L., and 

 M. aquatica, L., occur in Indian gardens, and as escapes. 



1. IH. sylvestriSj Linn. ; leaves broadly or narrowly oblong obovate 

 or lanceolate subacute / serrate hoary beneath, whorls in terminal spikes, 

 calyx-teeth triangular or lanceolate, corolla hairy glabrous within. Benth. 

 Lab. 171, and in DC. Prodr. xii. 166 ; Eeichb. Ic. Fl. Germ. t. 82. 



TEMPERATE WESTERN HIMALAYA and WESTERN TIBET ; from Kashmir to 

 Gurwhal, alt. 4-12,000 ft., Royle, &c. DISTRIB. Affghanistau, Temp. Europe and 

 W. and Central Asia. 



Stem robust or slender, 2-3 ft., hoary-tomentose. Leaves 1-3 by f-2 in., base 

 rounded or cordate. Spikes 1-3 in., -J in. diam. ; bracts lanceolate ; pedicels hairy. 

 Corolla lilac, about ^ in. diam. Nutlets usually pale, smooth, sometimes brown and 

 conspicuously delicately reticulate. 



1 have vainly endeavoured to find any character whereby to distinguish M. 

 incana and Royleana from M. sylvestris, the only available one afforded by the calyx 

 being excessively variable. Boissier unites them under one variety 8. petiolata (Fl. 

 Orient, iv. 513), distinguished from sylvestris proper by the hoariness and petioled 

 leaves, but 1 think the slender spike and usually minute calyx of incana are better 

 varietal characters. Strachey and Winterbottorn's specimens from Gurwhal (Niti, 

 alt. 11,500 ft.) appear to be typical M. sylvestris with purplish calyces. 



VAR. incana ; uniformly hoary-tomentose, spikes slender much interrupted, calyx 

 very small, teeth short. M. incana, Willd. Enum. Sort. Berol. 609 ; Benth. Lab. 

 170, and in DC. Prodr. xii. 169. Simla to Murree, Mooltan, Edgeworth. Sometimes 

 densely woolly. Peshawur specimens have small capitate spikes. 



VAR. Royleana; uniformly hoary-tomentose, spikes stout usually continuous, 

 calyx-teeth lanceolate or triangular with subulate lips. M. Royleana, Benth. in Wall.
