Scrophulariaceae
Species Description - A widespread species of lowland Tropical America, growing mostly on and near the seashore, but extending inland on river-banks, plains and waste land. Very variable, but with most states found in the same region or even in the same colony. Varies in size of leaves, in form of leaves from linear-lanceolate to nearly ovate, and in serration from entire to sharply serrate-dentate; varies in the length of the pedicels; varies in length of and attenuation of the sepals, in size of corolla from 8 to 10 mm. long, and somewhat pubescent or glabrous within anteriorly, and in capsules from oblong to ovoid, and from round and emarginate to acutish. Most conspicuously does the plant vary in pubescence, from glabrous throughout, through states with the stem pubescent and the pedicels glabrous or the pedicels sparsely pubescent—pubescent either with short or long hairs—to forms densely hirsute on stems, pedicels, sepals and the midribs and margins of the leaves. The last state (forma hirta* Loes. in Bull. Herb. Boiss. ser. II, 3: 284. 1903. "Habitat in Guatemala, in dept. Chiquimula in ruderalibus ad S. Juan Ermita: Sel[er] n. 3314." Isotype seen in herbarium New York Botanical Garden) prevails in Colombia.
