It may be (as per your earlier observations):

https://efloraofindia.com/2020/03/02/rubus-treutleri/

However, I now feel that images at both the above links may be of Rubus treutleri Hook.f.

Resembles moluccanus,

I guess … is right !

Thank you sir for the id. R.alceifolia ?

Lucid Central gives the following difference between the two:

Giant bramble (Rubus alceifolius) is often confused with Molucca bramble (Rubus moluccanus), which is sometimes also known as “wild raspberry”. These two species can be distinguished by the following differences:

giant bramble (Rubus alceifolius ) has relatively large leaves (8.5-20 cm long) with 5-7 shallow lobes. There are a pair of relatively large (about 15 mm long and 15 mm wide) leafy structures (i.e. stipules) on the stem near the base of each leaf stalk (i.e. petiole). The flowers are white and the fruit are made up of numerous segments (i.e. 110-180 carpels).
Molucca bramble (Rubus moluccanus) has relatively small leaves (4.5-15 cm long) that are unlobed or three-lobed. There are a pair of relatively small (about 12 mm long and 6 mm wide) leafy structures (i.e. stipules) on the stem near the base of each leaf stalk (i.e. petiole). The flowers may be white or pink and the fruit are made up of relatively few segments (i.e. 35-70 carpels).

Pl. check.

I think Rubus alceifolius has not been reported from India (but reported from Myanmar) so far on checking at net as per Catalogue of Life CABI WSSA Flora of China.
