unequal, lanceolate, serrate, acuminate, otherwise as in isophyllus.

 auriculatus, Nees in "Wall. PI. As. Ear." iii. 69 ; (fig. Bedd. "Ic. 

 PI. Ind. Or." t. 210). — Central India, in the plains. Leaves sessile, 

 auriculate ; spikes strobiliform, linear, oblong, velvety, 3-4 inches 

 long ; bracts obovate, obtuse ; flowers 1 inch, pale purple, tube 

 curved. 



callosus, Nees in "Wall. PI. As. Ear." iii. 85; (fig. "Bot. Mag." 

 t. 7538). — Central India. Leaves elliptic, acuminate ; spikes 

 strobiliform, more or less cymose, up to 4 inches long ; bracts 

 nearly 1 inch long, orbicular or elliptic ; corolla If inch long, blue, 

 tube ventricose upwards. 



COloratUS, Nees in "Wall. PI. As. Rar." iii. 89 ; (fig. "Bot. Mag." 

 t. 6922).— Sikkim, 2,000-4,000 feet elevation. , Leaves elliptic, 

 caudate at apex, serrate, glabrous, purplish beneath ; panicles 

 spreading, loose, capillary, very compound, leafless and bractless ; 

 bracts elliptic, early caducous ; corolla H inch, delicate pale blue, 

 tube ventricose. 



COnsanguineus, Nees, DC. " Prod." xi. 104 ; (fig. Bedd. " Ic. PI. Ind. 

 Or." t. 216). — South Indian mountains, up to 5,000 feet elevation. 

 Leaves ovate, acute, long-petioled, entire or crenate ; spikes 

 3-4 inches, filiform, simple or branched, glabrous or hirsute ; 

 flowers white or pale blue, f inch long ; bracts ovate-lanceolate, 

 glabrous or hirsute ; corolla ventricose from a contracted base ; 

 stamens 2 only. Mr. Clarke makes two varieties, but to me 

 (I have gathered quantities in various localities) it is all one 

 slightly variable species. 



CUspidatus, Nees in " Wall. PI. As. Rar." iii. 99 ; (fig. Bedd. " Ic. PI. 

 Ind. Or." t. 221).— S. India, mountains 4,000 to 7,000 feet eleva- 

 tion. Leaves ovate, long-petioled, white, silky underneath ; spikes 

 linear-oblong, 3 inches long ; bracts elliptic, § inch ; corolla 1 inch, 

 blue-purple, nearly glabrous ; stamens 2 only. 



Dalhousianus, Nees, DC. "Prod." xi. 174; (fig. Wight, " Ic." 

 t. 1509).— Himalayas, 6,000-8,000 feet elevation. Leaves elliptic; 

 flowers in capitate heads ; bracts small, caducous ; corolla 2 inches 

 long, glabrous, purple. I have had this in cultivation for many 

 years, raised from Indian seed ; it flowers well every summer. 

 See Collett, " Fl. Siml." p. 373. 



Dyerianus, Mast., " Gard. Chron." 1893, i. 442; (fig. " Bot. Mag." 

 t. 757 1). — Penang. Leaves ovate, acuminate, richly coloured with 

 bright rosy-purple all over the centre of the leaf ; spikes axillary, 

 small ; flowers pale blue, H inch long, funnel-shaped. Generally 

 grown for its very lovely coloured leaves. Young rooted cuttings 

 in small pots are most effective. It is a weedy-looking plant 

 when it grows large and flowers, as it then loses the colour in 

 its leaves. Young plants should be constantly reared in the propa- 

 gating frame, the old plants being thrown away. It is scarcely 

 worth growing for its flowers ; it flowers annually. See also
