Arceuthobium divaricatum Engelmann
(Pinon Pine Dwarf Mistletoe)
Family: Viscaceae
Status: Native
Synonyms:
Arceuthobium campylopodum Engelmann in Gray forma divaricatum (Engelmann) Gill
Razoumofskya divaricata (Engelmann) Coville
Arceuthobium divaricatum has scalelike leaves and is found growing on Pinon Pine. It is olive green in
color and generally less than about 10 cm long. Unlike the genus Phoradendron which is spread by birds,
Arceuthobiums forcefully eject their seeds from the drupes onto other suitable nearby hosts.
The specialized roots which penetrate host tissue are called "haustoria."
