Agelanthus pennatulus is a species of hemiparasitic plant in the family Loranthaceae, which is found in Tanzania, and Kenya.
A description of the plant is given in Govaerts et al., based on Polhill & Wiens (1999).
A. pennatulus has been found at altitudes of 1650–2400 m in both moist & dry evergreen forests. Recorded hosts are Olea, Strombosia, Maytenus and various Rutaceae.
The major threat is from forest clearance for agriculture (and forest disturbance).
