Eudicotyledons

The Eudicotyledons or "eudicots" with roughly 210,000 species or 71% of angiosperms (Christenhusz & Byng 2016), are by far the the largest plant group. As flowering plants, their reproductive structures are arranged as flowers and their seeds are enclosed in fruits. Typically flower parts are in 2's, 4's or 5's or multiples of 4 or 5. Leaves have netted venation, stem vascular bundles are arranged in a ring around the pith (= eustele), seeds have two seed-leaves (cotyledons), and pollen grains have 3 or more openings. Many familiar "wildflowers", "weeds" and most broad-leaved deciduous trees are eudicots. The sunflower family (Asteraceae), with about 260 local species, is the largest in the Pineywoods flora. The coontails (Ceratophyllaceae) a group of aquatic plants of uncertain taxonomic affinity,are also included in these galleries because recent evidence suggests that they are the sister group to the eudicots.
