Stem 2-3 ft., hairs spreading. Leaves membranous, more or less pubescent. 

 Whorls 1-2 in. diam., surrounded by the imbricating membranous appressed bracts, 

 which are quite unlike those of any other species. Calyx usually softly pubescent, 

 membranous ; hairs of mouth as long as the teeth.

 Islands, China. 



Stem 1-3 ft., branched above ; hairs spreading, deflexed or appressed. Leaves 

 sometimes 1 in. diam. Whorls small, f- in. diam., rarely axillary ; bracts fewer 

 and shorter than in the allies, filiform, ciliate. Calyx very constant in size and shape, 

 teeth erect or spreading horizontally, 



VAK. Walkeri ; branches long and strict, hairs appressed or spreading, leaves 

 very narrow 2-3 by - in. L. Walkeri, Benth. in DC. Prodr. xii. 531. Ceylon, 

 Walker, Champion. Bentham regards this as near L. hyssopifolia. Without 

 knowing whether it is annual or perennial, it is difficult to say whether it is a variety 

 of that plant or of L. zeylanica, of which it has the tall habit and solitary terminal 

 whorls. 



34. Xi. diffusa, Benth. Lab. 615, and in DC. Prodr. xii. 531 ; annual, 

 diffusely branched from the root, branches slender ascending hispid or 

 hirsute, leaves -1 in. linear or linear-oblong obtuse subentire, whorls 

 chiefly solitary and terminal few-fld., calyx J in. turbinate curved smooth 

 below ribbed and hispid above, mouth wide truncate, teeth small subulate 

 erect rather longer than the villi. Phlomis diffusa, Serb. Rottler. 



DECCAN PENINSULA ; Heyne, Wight, &c. 



This differs from L. zeylanica in the diffuse habit and small leaves. It has been 

 mixed in Wallich's Herbarium with L. nutans and L. dimidiata, Benth. (? of 

 Sprengel), which is the same as L. aspera. From the latter the habit, almost entire 

 leaves, smaller fewer-fld. whorls, and much shorter calyx with a wider truncate not 

 oblique mouth abundantly distinguish it.
