1 Horsfieldia squamulosa is related to H. coryandra, which generally has similar leaves (though usually with coarser venation), but differs in a more elongate male bud, (almost) glabrous androphore, and fruits with a pseudostalk of only 2 mm long. Vegetatively both species much resemble H. schlechteri from the same region, especially in the foliage. 2 Horsfieldia squamulosa forms a coherent group with H. clavata, H. coryandra, H. crux-melitensis, and H. clavata (the clavata-group), species of small trees or shrubs with club-shaped androecium consisting of a relatively large androphore and small sessile anthers at the apex. The remote species H. pulverulenta, H. sterilis, and H. triandra have somewhat similar androecia.
