Summary

Teppner H. 2010. Anther and anthesis in Pararchidendron pruinosum (Mimosaceae-Ingeae). – Phyton (Horn, Austria) 50 (1): 91–108, with 19 figures.

In pseudo-umbels of Parachidendron pruinosum (Benth.) Nielsen the flowers normally open successively during 3–4 days. The individual flowers, with corollas 4.5–5 mm in length, last five or six days in anthesis. The 22–28 stamens (8–14 mm long) form a brush, white on the first two or three days, then turning cream or light ochre-brown. Each of the two locules of a theca is divided transversally by a parenchymatous septum and the locule-halves contain one 16-grained, acalymmated polyad each. Anther wall anatomy and filament insertion are also considered.
