Taxonomy

1 Knema glauca is variable in a) the number of anthers, b) the mode of attachment of the anthers, i.e. stiped or not, and with upper side of the connective broad or narrow, hence, thecae opening ± downwards or laterally, c) the colour of the flowers inside, reddish or yellowish, and d) the size of the fruits. These features need more detailed study in the field. 2 Specimens from Central and E Java, Bali, and Borneo frequently have as many as 12-15 anthers, as compared to 8-10(-12) generally in W Java and other areas; in W Java, Sumatra, and Peninsular Malaysia 12-18 anthers is characteristic for the related species K. sumatrana. 3 As can be seen in the keys, Knema glauca belongs to a group of related (resembling) species, in which K. sumatrana is perhaps the one most closely allied; in most of their overlapping area morphologically intergrading specimens (leaf size, fruit size) can be found.
