Lower leaves up to 7 by 4 in., ovate-cordate, acuminate, bright green above, paler beneath with prominent pubescent nerves, decurrent at the base; petiole 2 in. long; upper leaves smaller, more deeply cleft, shorter petioled. Inflorescence racemose, terminal on the branches, narrow, erect, 6–10 in. long; branchlets short, bearing dense-flowered dichotomous cymes of 10–15 shortly pedicelled flowers; bracteoles minute, green. Calyx very small; tube subglobose, hispidulous with stellately spreading hairs; dorsal sepal linear-oblong, puberulous, nearly as long as the corolla-tube below its flexure; lateral sepals about half as long; two anticous segments small, linear, obtuse. Corolla bright blue, 1/2 in. long; tube suddenly deflexed a little above the short base, then ascending and again deflexed, forming a sub-campanulate laterally compressed throat; upper lip reflexed, obovate, with 4 short broad rounded lobes; lower lip rather longer, cymbiform, subacute.
