The genus Discoglypremna is perhaps most nearly allied to the genus 
Mallotus, Lour., but is readily distinguished by the 4-celled anthers, 
the receptacular glands associated with the male stamens, the anthers 
dorsifixed near the apex as in the gin Podadenia, Thw., and the 
well-marked hypogynous disk.—D. P
