Acanthaceae
Description:
Description - Variably pubescent perennial, sometimes erect, to 2 m, sometimes decumbent (especially in open, grazed habitats); leaves ovate or elliptic; inflorescence of terminal, leafy spikes with flowers in clusters in upper leaf axils; bracts oblong or oblanceolate, 6-12 x 1-3 mm; corolla orange-red, 18-23 mm long, not resupinate. In moist gullies in disturbed, usually seasonally dry forest and, less commonly, in rough, disturbed grassland, 200-2400 m. Dicliptera squarrosa is an exceptionally widespread species extending from Brazil south of the Amazon region westward to the eastern slopes of the Andes in Bolivia and Peru and then southward to Uruguay and northern Argentina. Its occurrence further north is uncertain though we feel that Dicliptera rauhii Wassh. from Peru belongs to this species and probably also several species described by Leonard from Colombia. D. squarrosa is very variable with a welter of different forms throughout its range all intergrading with each other and forming no discrete units except perhaps at a very local level. Presently we can make out the following 6 rather imprecise geographical forms, 5 of which occur in Bolivia.
Phenology - They flower throughout the winter season from about March to September.
