Burma : — Meiktila, Collett n. 877. 



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

 cm. long, 0-75 — 1 cm. across, distinctly gland-dotted ; racemes terminat- 

 ing in a few sterile coloured bracts, bracts 25 mm. diam., 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 ; 7iutlets 3 mm. diam, 



A very interesting species unlike any Indian Ocimum and belonging 

 to § Ocimodon (Iliantia) ; nearly related to the African 0. obovatano 

 and 0, jilannentosum,
