 DANIEL, THOMAS F.
Systematic relationships among various African (including Malagasy) and American (including West Indian) Acanthaceae recently have been shown to be closer than previously believed; several pairs of amphiatlantic genera, formerly treated as endemic to their respective hemispheres, have been shown to be congeneric.

The present phytogeographic links among Acanthaceae in Africa, Madagascar, India, and South America are indicative of a "Gondwanan" distribution pattern for the family and suggest an early radiation in southern land masses.

 Lamiales   (Site not responding. Last check: 2007-11-03)
Plocospermataceae are shrubby plants that may be recognised by their rather small, opposite leaves that are articulated near the base of the petiole, and their quite large, polysymmetric, campanulate-rotate flowers with versatile, extrorse anthers and a twice-divided style.
In other taxa like Acanthaceae there are no septal bundles, the gynoecial vasculature forming a sort of circle as a result (there are of course placental bundles: see Wortley et al.
As their distinctive alternative name Labiatae implies, Lamiaceae have always considered to be "eminently natural", being immediately recognisable because of their paired, serrate leaves, square stems, monosymmetric flowers, gynobasic style, and four nutlets, but the gynobasic style and the four nutlets have evolved more than once (Cantino 1992a).
