80 MISS L. 8. GIBBS ON THE FLORA AND PLANT FORMATIONS 
in Tenasserim (14.1.1839) and distributed under no. 2286. A Dissocheta 
collected by Haviland on Mt. Matang, Sarawak, at 750 m. is also referable 
to D. rubiginosa. None of these specimens have fully developed open 
flowers. Hence the dimensions given are liable to correction.
