Flowering 'Partridge Pea' populations dominate open, disturbed habitats of the Navasota Valley in mid-summer. As indicated by the detail), these plants are placed in the Fabales. Close inspection of the leaf that is said to be toxic to livestock but apparently favored by node reveals typical features of the family (an expanded petiole base or pulvinus and stipules) and an unusual extrafloral nectary on the petiole (usually termed a 'gland' in the keys). Features of this nectary, shape of the stipules, and the presence of
A less conspicuous denizen of open, disturbed sites in central Texas, Polypremum procumbens (Loganiaceae Gentianales Asteridae) is a small, diffusely branched herb with opposite leaves. The 4-merous, sympetalous flowers, ca. 2 mm in diameter, produce equally small capsular fruit. This taxon, the only representative of its genus, is endemic to North and Central America and quite common in eastern Texas. However, it has no 'common' or 'local' name.
Gynoecia of the American Beautyberry (Callicarpa americana - Verbenaceae), contained within the calyx just after anthesis several weeks ago, have now expanded to maximum diameter. Typical coloration of mature fruits will be established by October. This plant is less common than Polypremum procumbens in Texas, at least in terms of number of individuals per unit area. Its fruits are, however, quite evident to animal vectors and those that provide 'common' plant names. Thus, Callicarpa americana is also known as French-Mulberry, Bermuda-Mulberry, Sour-bush, Bunchberry, Filigrana de Mazobca, Filigrana de Pinar, Foxberry, Purple Beautyberry, Spanish-Mulberry, and Turkeyberry.
