THE EVOLUTION OF POLLEN TETRADS IN ONAGRACEAE

American Journal of Botany, 1975
In Onagraceae, pollen is shed in mature tetrads in most Epilobieae, many species of Ludwigia (Jussiaeeae), and two closely related species of the large genus Camissonia (Onagreae). Mature tetrads of Camissonia cardiophylla and representative species of Epilobium and Ludwigia were examined with light, scanning, and transmission electron microscopes ...

A CLADISTIC ANALYSIS OF CIRCAEA (ONAGRACEAE)

Cladistics, 1990
Abstract— Circaea (Onagraceae), a genus of seven species from the northern hemisphere, forms a monophylctic group defined by the following synapomorphies: two stamens (opposite the sepals), fruits indehiscent capsules, hooked hairs on the fruits, and perianth parts reduced to two. A cladistic analysis of the genus was performed using 22 characters from

Pollen morphology of the Onagraceae

Review of Palaeobotany and Palynology, 1967
Abstract This incomplete but comprehensive survey based upon the pollen of 21 genera and over 100 species of the Onagraceae shows the following pollen types: 1. ( 1 ) Pollen in tetrads and disarticulated tetrads. The single grains usually have a thicker ring at the base of the somewhat aspidote pore. This condition occurs in Epilobium (in part),
