Ehretia amoena (SA Tree List No. 656), the sandpaper bush or in Afrikaans skurweblaarbos (rough or coarse leaved bush), grows in South Africa only in the far northeastern parts, typically near rivers or in bushveld. This tree is more widely known in Africa as it grows in several countries to the north and also in Swaziland and Mozambique.
The leaves are obovate with dark green hairy surfaces, rough to the touch. The base tapers narrowly while the tip may be rounded, notched or also tapering. The flowers are fragrant, white, blue or sometimes pale mauve. The corollas are funnel-shaped with lobes that curve back. The calyx has triangular lobes. Flowers grow in spring and summer in lax terminal panicles (Coates Palgrave, 2002; Schmidt, et al, 2002).
