Dubyaea forrestii Mamgain & R. R. Rao (Edinburgh J. Bot. 65: 1. 2008) was described from rocky alpine slopes in Gaoligong Shan in NE Myanmar, close to the border with China or possibly inside Yunnan ("[F]lank of the N’Maikha-Salwin [Nu Jiang] divide, lat. 26°30′N, alt. 11,000′ [3700 m]"). It was described as being similar to D. atropurpurea and is known only from the type, G. Forrest 29660 (holotype, BM; isotype, E), collected in 1931.
