Big parts of the two-lipped Salvia africana-caerulea corollas are white, in spite of the name part, caerulea, a Latin word meaning blue, azure or sky-blue. The blue on show varies in pale shades, darkest in the dots in the centre of the lower lip and about palest on the stubbly exterior of the upper lip or hood.
More blue is contributed by the two-branched, down-curving style that emerges like a snake tongue from under the hood. Some obscure whitish and dark brown stamen appendage parts extend in front of the the upper lip lower than the hood.
The barrel- to funnel-shaped calyces that have lost their corollas are green with protruding purple and hairy ridges ending in longish, narrow lobes. Similar to the corollas, the calyces are not regular in shape as radially symmetrical flowers (Manning, 2007; Leistner, (Ed.), 2000; Andrew, 2017; iNaturalist).
