Asystasia gangetica subsp. micrantha or A. intrusa corolla tubes

The corolla tubes of Asystasia gangetica subsp. micrantha or A. intrusa, the African coromandel, are longish and asymmetrically funnel-shaped before the elaborate flare in the separating lobes. The tubes bend down slightly, presenting more or less horizontal surfaces for pollinators to walk on. The lower lobes of the flowers protrude angled down, possibly a bit helpful for arrivals short of gas.

The green calyx lobes clutching the back ends of the corollas are acutely pointed and comparatively small. The pedicels are short. The flowers face to one side of the axis, the buds erect.

The scrambling plant stems are here about prostrate, their tips lifted for presenting the flowers (Leistner, (Ed.), 2000; Pooley, 1998; iNaturalist).
