dots, sub-triplinerved at the lm,se ; midrib prominent underneath, lateral 

 veins loose and inconspicuous. Spike terminal, furnished with the bract- 

 like leaves close below, erect, cylindrical or oblong- sometimes ellipsoidal- 

 cylindrical, lj-4| cm long, 1-1| cm broad, composed of confluent verticil- 

 Listers and numerous crowded flowers. Bracts minute, linear or linear- 

 lanceolate, usually shorter than the flowers, but often longer than them in 

 the inferior ones, pubescent and ciliated, covered with many minute 

 glandular dots ; bractlets shorter than the flowers, linear, narrowed below, 

 pubescent and ciliated. Verticillasters sessile, closely placed, densely 



flowered. Flowers minute, with very short and pubescent pedicels, 7-8 

 mm long. Calyx obovoid-campanulate, 21-3 mm long, obtuse at the base, 

 thin in texture, pubescent and glandular externally, thinly and very shortly 

 even obscurely pubescent internally, with 5 main nerves running each 

 towards one lobe; veinlets loose and obscure; lobes 5, equal, deltoid, acute, 

 ciliated, erect, shorter than the tube. Corolla violet-lilac, exserted, 3J-4 

 mm long, thin ; tube included or just exserted, narrow, somewhat and 

 gradually enlarged above, with longitudinal nerves, glabrous; limb 4— fid, 

 S} treading, subequal, slightly pubescent and glandular externally, often very 

 thinly ciliated, the posterior lobe broader than the anterior ones, deltoid, 

 acutish, the anterior lobes 3, ovate, obtuse. Stamens 4, much exserted, 

 inserted <>n the corolla-tube and alternate to the lobes, straight at full 

 anthesis, 5-6 mm long, sub-equal, the two posterior ones very slightly shorter 

 than the two anterior ones ; filament filiform, minutely villosulate below 

 and densely and manifestly barbate at the middle part with delicate 

 violet-lilac hairs which are seen to be moniliform under the microscope ; 

 anther minute, terminal, sub-reniform, confluent into 1-cell, transversely 

 dehiscent on the fore side, the valves explanate after dehiscence'. Disk 

 equal, entire, thick, somewhat longer than the ovarian lobes. Style longer 

 than the stamens, filiform, glabrous, 2— fid at the top ; lobes divergent, 

 Blenderly subulate, slightly carved outwards, equal in length. Ovary-lobes
