Chinese Ixora, Chethi (Malayalam);

 

Small shrub up to 1.5 m tall; leaves oblong, elliptic to elliptic-obovate, 6-9 cm long, gradually narrowed to rounded base, subsessile with petiole barely 2-3 mm long; pink to orange in trichotomously branched corymbose cymes, of the three flowers in each cyme central sessile, lateral with 2-3 mm long pedicel; calyx lobes minute; corolla tube 20-30 mm, lobes elliptic, 5-8 mm long, apex broadly obtuse to rounded; fruit reddish-black, subglobose, 6-7 mm long.
Looking similar to I. coccinea in smaller flowers but obtuse (and not acute) corolla lobes and leaves subsessile (and not sessile).

Not Ixora coccinea …, which has sessile leaves and acute corolla lobes. This should be I. chinensis

Ixora coccinea L. ??


Yes, it is.


Looks like more than one species. Leaf base stem clasping nearly sessile, petals with pointed tip is true I . coccinea.

All from one place.


May be Ixora chinensis Lam. (Cultivated)- Ixora chinensis looks similar to I. coccinea in smaller flowers but obtuse (and not acute) corolla lobes and leaves subsessile (and not sessile).
