Abstract
Pavetta glaucophylla Retief, S. J. Siebert
& A. E. van Wyk, a new species of the Rubiaceae
(Ixoroideae) from South Africa, is described and
illustrated. A member of Pavetta L. subg. Pavetta, it
has a restricted range and is near endemic to the
Sekhukhuneland Centre of Endemism. Hitherto P.
glaucophylla has mainly been confused with P.
zeyheri Sond., from which it differs in being a taller
plant with larger, blue-green leaves in living
condition instead of dark green to gray-green leaves
and flowers in which the calyx lobes are 0.5–0.75 mm
long and triangular-ovate, and 1.25–2 mm long and
not triangular-lanceolate, as in P. zeyheri.
