...% of the count. A second difference between the Homerian and Clamgulchian is the increased diversity of herbaceous groups (such as Ranunculaceae, Urticaceae, Onagraceae, Primulaceae and others), which are few in the Homerian (∼4–5 taxa), but many in the Clamgulchian (≤15–18 taxa). These herb groups show...

... the state. The assemblage contains 17 terrestrial forms and four to five brackish to marine forms of dinoflagellate cysts or algal taxa. Angiosperm pollen forms are comparable to extant taxa including the palms, Bombacacidites (Bombacaceae), Corsinipollenites (Onagraceae), Milfordia (Restioniaceae...

... quite smooth, and most often viewed in an oblate (flattened) state. The viscin threads are on the proximal and distal sides of the pollen and vary in length; they appear to have a simple morphology unlike the complex, rope-like threads seen on pollen of the Onagraceae and some other angiosperm families...

Palynotaxonomy was also one of the main topics of Enrique’s research, and this comprised work on several botanical families such as the Amaranthaceae, Chloranthaceae, Cornaceae, Fabaceae, Moraceae, Nyctaginaceae, Onagraceae, and Rubiaceae (Ludlow and Martínez-Hernández 1978 , 1979...

The Paleocene pollen are assignable to the Onagraceae, and represent the earliest known record of this family. The Onagraceae had not previously been...
