Notes
USES. None recorded on specimens from our area CONSERVATION Protected in the National Park; least concern (LC) F1 hybrids of D. keniensis x D. keniodendron are occasionally found on Mt Kenya (named as Senecio ¬ saundersii W. Sauer & E. Beck), but with no evidence of back-crossing or the maintenance of hybrid swarms there is little reason to recognize formally such hybrids.
