Notes: This species is characterized by its robust habit; its large, rather narrowly elliptic, petiolate, generally subcoriaceous leaves that are sharply acuminate at the apex and usually dry with a dark brown color and the venation not very evident; its pedunculate, several- to many-flowered, lax inflorescences with developed bracts; its sessile to very shortly pedicellate flowers with triangular calyx lobes and long, white to pink or red corollas with the tube (10)15-22 cm long; and its medium-sized fruits. This species has been commonly collected, particularly in the Masoala Peninsula region. Ixora siphonantha has been confused with several other, less commonly collected Ixora species with coriaceous petiolate leaves and long corollas, in particular Ixora crassipes, Ixora densithyrsa, and Ixora mocquerysii. De Block (2007) noted that although the pollinators have not been observed, this species is certainly pollinated by hawkmoths.
