Stamens inserted at 1.4-2.5 mm from corolla base which is 0.56-0.71 of tube length; Ovaries 0.6-0.9 mm high, pubescent in tuft between carpels or very sparsely pubescent around base only; Fruit with 1-7 articles in a string, 1.6-9.3 mm between articles, stalks 2.8-7 mm long; Seeds oblong, 4.9-8.1 by 4-5.3 by 3.5-4.2 mm.
The inflorescence of this species is usually a single axis with whorls of flowers at the nodes. Specimens with a more complex branched inflorescence may actually represent another species or a variety of this species but unfortunately the material is too poor to be sure.
