106. LABIATJE. [7. Coleus. 



thyrsoidly panicled stalked 2-chotonious cymes in the axils of the 

 leaves or bracts. Calyx •12" campanulate, pubescent, snb-2-liiDped, 

 teeth sharply lanceolate ; in fi'uit decurved. Corolla hairy, tube 

 •15--16", equalling or exceeding the lower lip, declinate, suddenly 

 swollen above the very short base, gibbous above. 



In wet grassy places, also on cool hill sides but then less tall ; Neterhat, 3000 ft. ! 

 Fl., Fr. Octj-Dec. 



Very aroniatic. Leaves pubescent both sides. Cymes divaricate, "5" long. 

 Upper lip of corolla with 4 rounded lobes and violet markings, lower boat-shaped, 

 pale blue. Filaments declinate, 2 lower longer. Nutlets oblong. 



This, as Clarice states, is probably only a variety of P. coetm. I class it under 

 P. menfhoideg because the corolla-tube in P. coetsa is much shorter than the 

 lower lip. 



3. P. incanus, Link. 



An erect coarse herb or undershrub 3-4 ft. high Avith square stems, 

 long-petioled velvety ovate cordate crenate leaves 2-1" by 1-75-4" 

 with a strong smell, and terminal racemes or panicles of small pale- 

 lilac flowers "3" long, arranged mostly in opposite peduncled 2-fld. 

 cymes in the axils of small green bracts •15--25" long. Calyx -12" 

 long, enlarged to •45" in friiit with an upper broadly ovate lip and a 

 lower lip with 4 long subulate teeth. Seeds grey-brown subglobose 

 with sparse small dark warts. 



Waste ground near villages under shade, or among rocks or in the open on the 

 pats. Singbhum ! Ranchi plateau, common ! Parasnath, Kew Herb. ! Fl. Aug.- 

 Sept. Fr. Oct. 



The name is not a very happy one as the plant, although shortly softly puloescent, 

 is scarcely grey or hoary. L. acute, deeply cordate, gland punctate beneath. 

 Lower petioles 3-4!" long. Cymes of 2-3 fls. on a short common peduncle with 

 pedicels 'S-'o". Corolla pubescent, tube only slightly exserted, boat-shaped lower 

 lip about •2".
