Though this has been several times collected in the mountains of the Malay 
Peninsula by different collectors, 16 seems to have been eonfused with 
Р. venenosa, Juss. Its smaller flowers on very short pedicels, as well as 
its dwarf stem and dense erect raceme, make it very distinct from the 
great spreading half-shrub which is common in the lower damp forests ; 
and it is difficult to see how it could be considered a variety of P. venenosa, 
which is really much less variable than would appear from the number 
of varieties of it recorded.
