Gynochthodes can tropical, subtropical, temperate, and arctc regions be segregated from other genera of the tribe Morindeae (Davis et al. 2009). The subfamily classifcaton based by having inforescences that are never paniculate, on morphological characters divided Rubiaceae into small fowers (corolla tubes 0.7–5.5 mm long and four subfamilies, viz., Cinchonoideae, Ixoroideae, corolla lobes 1.5–11.0 mm long) and partly exserted Antrheoideae, and Rubioideae (Robbrecht 1988), anthers (Razafmandimbison et al. 2009; Suratman though recent molecular phylogenetc studies recognize 2018). Razafmandimbison et al. (2009) also discussed three subfamilies such as: Cinchonoideae, Ixoroideae, the circumscripton of Gynochthodes in a wider sense and Rubioideae (Bremer 2009). One of the tribes of the to accommodate all lianescent species of Morinda with subfamily Rubioideae is Morindeae (Bremer & Manen small fowers in order to make Morinda monophyletc 2000; Bremer & Eriksson 2009), which is comprised based on molecular phylogeny. The majority of of six genera namely, Appunia Hook.f., Coelospermum lianescent species of Morinda having multple fruits Blume, Gynochthodes Blume, Morinda L., Pogonolobus have been transferred to Gynochthodes and necessary Muell., and Siphonandrium Schum. (Razafmandimbison nomenclatural changes made (Razafmandimbison & et al. 2008). Bremer 2011). According to Johansson (1987), the genus Blume (1827) described the genus Gynochthodes can be distnguished from Morinda by its lianescent by putng together the species having similar habit, stpules and bracts with marginal hairs, terminal morphological features such as presence of 8–9 fowers umbellate inforescences, fowers with recurved calyx per umbel on the inforescence, fowers being villous tubes, corollas with long hairs within the tubes and inside the tube; 4–5 stamens, one style, bifd verrucous on the adaxial side of the lobes.
