Systematics studies of for Shorea spp. in Sarawak.
Shorea is one of the genera in family Dipterocarpaceae of tribe Shoreae that is diversely distributed in Borneo. It is locally known as Meranti and about 2/3 of the species in Borneo are endemic to Borneo. Detail descriptions of pollen of genus Shorea were still limited. Hence, a study on comparativ...
