P. columnaris appears to have affinity to P. lanceolata Brandeg. of Series 10. 
Notable in P. colwmnaris are the very slender anthers, as shown in Fig. 7. 
They are erect, usually adnate and forming a column around the shortly exserted 
style. The species has very distinctive red matted waxy appearing tomentum 
and dendroid hairs with numerous short slender branches. The thin, slender, 
essentially entire leaves with red stellate appressed pubescence on undersurface 
and the very slender flower buds together with long pedicels further distinguish 
the species. In late flowering stages, young fruits and flowers are present in the 
same corymb.
