 many-flowered, peduncled, axillary, usually 2 to an axil and one of them 

 simple and other divaricately pauci-ramose or sometimes developed into a 

 peduncle-bearing branch, longer or shorter than leaves, the superior ones 

 forming a loose panicle with or without small leaves; rachis slender, filiform, 

 adpressed-puberulent, about 2-10 cm. long ; peduncle not long, nearly gla- 

 brous, about 1-3 cm. long. Flowers small, about 7 mm. across, white, pedi- 

 cellate : pedicel gracile, patent in flower but then more or less reflexed and 

 free from deciduous flowers, puberulent with adpressed minute hairs, virides- 

 cent, shorter or longer than the flower, 2J-6 mm. long. Calyx : lobes 

 patent, minute, subulato-linear, dilated at the base, obtuse, entire, glabrous, 

 very sparingly ciliated, membranaceo-herbaceous, 1-nerved, light green, 1J- 

 l|mm. long; tube depressed-pateriform, thin, glabrous, about 2mm. across. 

 Corolla adnately inserted at the calyx-tube, patent, rotate ; lobes much 

 longer than the tube lined to the calyx-tube, ovato-oblong to oblong-lanceo- 

 late, obtuse or acutish, entire, membranaceous, 3-nerved, puberulent and 

 ciliated with short and minute verruculose hairs, about 2-times as long as 

 the calyx-lobe, 3 mm. long, 1-J mm. wide. Stamens 3, inserted at the 

 base of calyx-tube, erect, approximately placed, free, glabrous, opposite to 

 corolla-lobes, about 1 mm. long ; filament linear, straight, very hardly shorter 

 than or equal to the anther in length ; anthers erect, extrorse, about f mm. 

 long, one unilocular and oblong-elliptical, two bilocular and didymose, lato-
