I believe this is *Swertia cordata*, which has the following characteristics:
Stem leaves are stalkless, ovate to ovate-heart-shaped, 0.8-2.3 cm
long, 0.5-1.2 cm broad, base heart-shaped and nearly stem-clasping,
margin rough, tip pointed, veins 3-5.
Flowers are borne in narrow, dense, many-flowered thyrses 13-40 cm.
Flowers are 5-merous. Sepals are lanceshaped to ovate-lanceshaped,
5.5-7 mm long, margin rough and usually slightly curled, tip pointed.
Flowers are white, with purple veins, 1-1.5 cm in diameter. Petals are
narrowly elliptic to elliptic-lanceshaped, 0.8-1 cm long, tip pointed.
At the base of each petal, is a circular greenish, viscous spot.

All these characteristics agree well with my plant.

In additions to this, stems of Swertia cordata are supposed to be 4-
angled, with wings on angles. Narrow wings can be seen on the stem in
the 2nd image.
