 wide, rarely rather larger low down on the stem ; petiole -6 to 1-5 in. 

 long. Floioers in dense whorls, distant below, approximate above in a 

 dense spicate inflorescence ; in fruit the cymes sometimes subsecundly 

 explanate ; bracts -15 to -2 in. long, linear, beset with long firm hairs. 

 Calyx -25 in. (in fruit -35 in.) long, subsessile, hirsute with firm hairs ; 

 teeth lanceolate, acute, almost as long as tube, hairy within and without, 

 ciliate. Corolla -6 in. long, light-purple with blue lower lip ; tube -2 in. 

 long ; lower lip l:-lobed from deep division of the middle segment into 

 two oblong lobes ; the lateral lobes small, rounded ; upper -25 in. long, 

 oblong, entire. Filaments hirsute. Nutlets -1 in. long, wide-ovate, 

 subcompressed ; inner face bluntly angular, outer rounded, smooth,

 generally ; China. 



A very variable plant as regards tomentum ; the extreme forms being A. glabrata, 

 Benth., which is only sparsely hairy, and A. mollissivia. Wall., which is densely 

 softly woolly-pubescent. The two forms mentioned are probably deserving of separa- 

 tion as varieties ; intermediate states, however, occur.
