Discussion
: This
variety was
initially described at species level by Bamps (1962) on account of its narrow, almost linear leaves; it also tends to have less tomentose inflorescence than the
type
variety. The new specimens identified show that the variety is widespread in the Upemba region, where the other two varieties [
var.
coerulea
and
var.
obovata
(Robyns & Lebrun) Vollesen
] are rare or lacking.
