Doubtful Species 
D. perakensis Kranzl. Notizhl. Kgl. Bot. Gart. Berlin , 1907, 294. 
From Perak, Gunong Hijau (Schlechter). I have not seen 
nor can make out from the description what this plant can 
be. Kranzlin gives it as of section Didymanthus, as he does 
his D. Schlechteriana, which is obviously Parabcea cordata, but 
does not seem certain that it is a Didymocarpus at all. The 
locality has been so well explored that it is highly improbable 
that the plant has not been previously described.
