Habit: Herb or Shrub

Habitat”: Hill slope, shady place

Location: Ruma, Bandarban

Flowering: December

Oxyspora paniculata, Melastomataceae

Maybe Osbeckia rostrata Don (if glabrous) or O. stellata Wall. (with rigid hairs).

But the color of flower is pink to purple regarding Osbeckia rostrata Don (if glabrous) or O. stellata Wall. (with rigid hairs). But its color is blue

Also similar with Tibouchina urvilleana flower

I agree 100% with …

Strangely though ‘Bengal Plants’ doesn’t feature this!

They flowing information regarding 2 species (as per “Encyclopedia of Flora and Fauna of Bangladesh, Volume 9”)
1. Oxyspora cernua: In Bangladesh, this species was reported from Chittagong District (Heinig,1925)
2. Oxyspora vagans: In bangladesh, it occurs in the forest of Chittagong and Sylhet districts (Heinig,1925;Alam,1988).

… informs that two Oxyspora are found in Bangladesh (as per “Encyclopedia of Flora and Fauna of Bangladesh, Volume 9”) –

Oxyspora cernua
Oxyspora vagans

Flora of British India, vol2, p526 also informs this and both looks similar to paniculata.

Since leaf margin seems to be entire (against denticulate in remaining two species) in this plant it may be Oxyspora cernua (Roxb.) Hook. f. & Thomson ex Triana.

Oxyspora cernua and O. vagans are supposed to differ in their lower leaf surface, but that is invisible in these two photos.
