cf. Endressistemon sp. 2

Text-fig. 29c, d

Description and remarks. The material comprises a single stamen fragment, about 0.8 mm long including the apical projection, and about 0.3 mm broad. The apical projection is compressed covering the distal portions of the thecae (Text-fig. 29c).

Pollen grains in situ are poorly exposed and the aperture configuration is uncertain, although it is clear that the grains are not tricolpate and we assume that the pollen is monoaperturate. Pollen is semitectate-reticulate, circular in equatorial view, about 9 µm in diameter. The reticulum is homobrochate and only loosely attached to the main body of the pollen (Text-fig. 29d).

Affinity and other occurrences. The stamen fragment is closely similar in general morphology to the individual stamens of Endressistemon cateficensis, but slightly larger and the reticulum of the pollen grains is more open and only loosely attached to the main body of the grains.
