Microloma calycinum long, straight sepals

The narrow, spreading to angled-up sepals below the corollas of the Microloma calycinum flowers may be bright red, pink in various shades, or as here a subdued cream. The sepals are longer than in most of the other Microloma species and as long as or longer than their own corollas. M. incanum has pale flower colouring, its sepals shorter and often seen cohering around the ridged corolla tube.

The somewhat rosy M. calycinum corolla has five tufts of deflexed hairs inside the tube near its base.

The twisting of the closed Microloma corolla lobe tips is erratic in the flowers of the genus, present in some flowers (Grenier, 2019; Manning, 2009; Le Roux, et al, 2005; iNaturalist).
