1. L. urticsefolia, Br. 



An erect hairy herb with square pubescent stems 1-2 ft. high and 

 nettle-like ovate to lanceolate coarsely obtusely serrate leaves l-2'o''' 

 long. Flowers white in very dense globose whorls -7-1" diam. 

 supported by linear or subulate-lanceolate hirsute bracts -S-'S" long. 

 Calyx membranous, reticulate, •4--5" long with very oblique mouth, 

 split above, ribs produced into spinulose teeth. 



Patna, Madden ! Fl., Fr. Dec-March. 



A very distinct species. L. softly pubescent beneath with 4-5 raised sec. n., base 

 sometimes shortly suddenly cuneate on the "i-'S" long petiole. 



2. L. lanata, Benth. 



Woody below with many stems 8-18" from a stout stock, densely 

 wooUy-tomentose all over or (in our variety) indumentum of longer 

 less woolly hairs, always spreading or suberect (cp. montana). 

 Leaves 1-2" ovate, rounded or obtuse, crenate, base sometimes 

 subcordate. Lower petioles up to 5" long, uppermost leaves sub- 

 sessile. Whorls sessile dense. Calyx •22--25", ribs excurrent 

 as linear unequal teeth -09' or less, tube shortly finely sericeous 

 within except at base. Corolla *3-"35', tube included, lower lip "Z". 



The typical plant has not been found in our area and is Himalayan. Var. 

 nagpurengis occurs on Parasnath (see below). Var. Candida occurs on the hills of 

 the Central Provinces, and is easily distinguishable by the beautiful dense pure 

 white tomentum and broadly ovate rounded leaves, larger flowers and calyx-teeth 

 up to '09. It appears to me to be separate from true L. Janata and also from the 

 Parasnath plant. It possibly occurs on the higher Sirguja mountains. Fl., Fr. 

 Oct.-Dec. 



Var. nagpurensis, G. B. Clarice. 



Stems sometimes "2" diam. at base. Leaves ovate to lanceolate-ovate subacute 

 densely sericeous-tomentose beneath and less so above, rather coarsely and obtusely 

 serrate or dentate-serrate, sec. n. 3-5. Whorls lO-20-fld. Calyx with minute subu- 

 late teeth only "01" long. Corolla "3", upper lip contracted at base, suborbicular 

 above, shorter than the lower. Calyx sericeous within one-third of the way down.
