Burma :— Meiktila, Gollett n. 877. 



Apparently perennial, stems more than 30 cm. high ; leaves 2 - 5 — 3'5 

 cm. long, Q'75 — 1 cm. across, distinctly gland-dotted ; racemes terminat- 

 ing in a few sterile coloured bracts, bracts 25 mm. diani., pedicels 1 — 4 

 mm., calyx 3 mm. long 2 mm. across (fruiting 8 mm. long 4'5 mm. across, 

 lower teeth strongly aristate), corolla tube 8"5 mm long, externally 

 puberulous as are the lips, lower lip 3'5 mm. long ; stamens 10 mm. 

 long ; nutlets 3 mm. diam. 



A very interesting species unlike any Indian Ocimum and belonging
