Garcinia assamica is a newly discovered species of plant found in areas near Manas National Park, Assam. It seems to be rare and is hitherto only known from very few individuals, near to a rivulet. This new species is allied to Garcinia nigrolineata in arrangement of flowers on axillary short spikes; arrangement of stamens on a convexdisc and number and arrangement of staminodes in female flowers; but it is distinct from the latter in having greenish-yellow (not yellowish) exudate; 2âÂÂ5 female flowers fascicled at nodes against solitary flowers; 4âÂÂ5-locular ovaries against 5âÂÂ7-locular ones.
