Racemes dense, slightly or considerably elongated in fruit, (flower buds narrowly oblong). Fruiting pedicels usually horizontal to divaricate, rarely ascending or reflexed, usually straight, rarely incurved, slender or stout, (2-)3-9 (-13) mm, often strongly flattened, rarely not flattened at base. Flowers: sepals erect, linear to linear-oblong, (3-) 3.5-5.5(-7.5) × (0.5-)0.8-1(-1.5) mm; petals white or lavender to purple, spatulate to oblanceolate, (4.5-)6-9 (-13) × (0.5-)0.8-1.5(-2.3) mm, margins not crisped, claw differentiated from blade, [slender, (2-)3-4.5(-7) mm, narrowest at base]; nectar glands lateral, flat or toothlike, median glands absent; filaments subequal to slightly tetradynamous, (3-)4.5-7.5(-12.5) mm; anthers exserted, linear to narrowly oblong, (1-)1.5-2.5(-4.5) mm, not circinately coiled; gynophore 0.5-2(-5.5) mm. Fruits usually horizontal to divaricate-ascending, or ascending, rarely reflexed, usually torulose, rarely submoniliform, usually strongly incurved, sometimes straight, rarely arcuate, terete, (0.8-)1.4-6.5(-8) cm × 1-1.3(-2) mm; ovules 14-40 per ovary; style usually cylindrical, rarely subclavate, 0.5-1.3(-3.2) mm.
