ticillasters axillary, 1-3-flowered ; bracts sometimes present at 

 the basal sides of the verticillaster, leafy, green, narrowly ob- 

 long, few-dentate above. Flowers not large, sessile or subses- 

 sile, collectedly approximate ; bracteoles opposite at the base 

 of the flower, linear, acuminate, entire and ciliated, pubescent 

 externally, glabrous internally, 1-nerved, 2^-5 mm. long. Calyx 

 equal, green, herbaceous, membranaceous, pubescent externally, 

 arid also so internally above, persistent, 8-10 mm. long in 

 flower, but scarcely accrescent attaining about 12 mm. long and 

 open in the throat in fruit, 5-costate and with 5 accessory weak 

 intermediate veins, very loosely reticulated between the costas 

 and intermediate veins; tube obconically tubuloso-campanulate, 

 longer than the teeth ; teeth 5, equal, erect-patent or patent, 

 deltoid-subulate, acuminate in spinescent form at the apex but 

 not rigid, entire and ciliated, about 2§-4 mm. long, 3-nerved 

 with a strong midrib and 2 intramarginal accessory weak veins, 

 very loosely reticulated between the midrib and marginal veins. 

 Corolla much exserted, erect, membranaceous, openly bilabiate, 

 purpurascent, deciduous, about twice as long as the calyx and 

 14-21 mm. long ; tube angustate, straight, slightly enlarged 

 above, thinly pubescent with retrorse hairs and very minutely 

 granulato-glandular except towards the base externally, deli- 

 cately 10-nerved in middle ; annulus above the base within, 

 pilose with straight hairs anteriorly but interrupted posteriorly; 

 limb shorter than the tube ; posterior lip erect, obovato-ellip- 

 tical, concave in front, subgaleate, entire, rounded or sometimes 

 emarginate at the apex, ciliated, subdensely pubescent with 

 erect or suberect hairs and very minutely granulato-glandular 

 dorsally, about 5-8 mm. long, nerves several and loosely anas- 

 tomotic between them ; anterior lip about as long as the pos- 

 terior lip, horizontally patent, broad, about 5^-10 mm. wide, 

 3— fid, glabrous on the upper surface except the throat, which 

 is often minutely puberulent, thinly pubescent with antrorsely 

 adpressed hairs mixed with granular glands on the under sur- 

 face ; the face sometimes with 2 approximate ridges in centre ; 

 midlobe somewhat larger, orbiculate or broadly orbiculate, 

 rounded or truncato-rounded at the apex, very shortly stipitate
