 to 20 in. in diam. of stem ; branchlets rather slender, dark brown, 

 glabrous, with prominent usually elongated lenticels. Leaves coriaceo- 

 chartaceous; 3-foliolate, the leaflets all petiolulate, glabrous, entire; 

 leaflets ovate or ovate-lanceolate, acuminate often bluntly at apex, 

 rounded or cuneate at base, the side leaflets sometimes slightly asym-

 ones usually about one-third smaller ; midrib slender, raised beneath ; 

 main nerves 12 to 24 pairs, usually regularly spaced and parallel, only 

 slightly curving to the margin and then anastomosing in an obscure 

 looped marginal nerve, all raised beneath ; secondary nerves and reticu- 

 lations firmly netted ; petiole 1 to 2 in. long, slender ; petiolules about 

 •5 in. long, the middle one only slightly longer than the others. 

 Particles terminal, with sometimes additional branches from the axils 

 of the upper leaves, minutely puberulous, sessile, many-flowered, reach- 

 ing sometimes 12 in. in length ; rachises very slender, puberulous, 

 obscurely 4-angled ; branches at first 3-chotomous, ultimately ending in 

 slender dichasia ; bracts many, conspicuous, persistent, linear-lanceolate, 

 •25 to '75 in. long ; bracteoles 2 to each pedicel, similar but slightly 

 smaller ; pedicels slender, sometimes ; flowers small, pale blue or 

 white. Calyx-tnhe campanulate, pubescent and with glandular dots 

 without, -05 in. long ; teeth 5, acute, '025 in. long ; in fruit much 

 enlarged, cup-shaped. Corolla small, 2-lipped ; tube •! in. long, pubes-

Briihl's description, with drawings, in the Calcutta Herbarium, is most complete, 

 and has been of great use, especially as perfect flowers are very few on the specimens 

 available.
