The revealed as Deutzia compacta Craib under family Hydrangeaceae
Can it be Deutzia staminea as per images herein ?
Deutzia corymbosa R.Br.
The plant seems to be matching well with this species, but is not featured on our database, nor on Flowers of India, nor eFlora of India. The name is considered accepted according to TPL, World Flora Online and Kew Database. Catalogue of Life considers it  ambiguous synonym  for Deutzia hookeriana (Schneid.) Airy Shaw

To me appears similar to images at Deutzia staminea
Flora of Pakistan only mentions this species with distribution as N.W. Himalayas, Kashmir, Nepal & N. China along with Deutzia scabra Thunb.
Checklist of Nepal mentions this with distribution as Himalaya (Kashmir to Bhutan) along with Deutzia bhutanensis Zaik. (E. Himalaya (Nepal to Bhutan)) and Deutzia compacta Craib (syn: Deutzia corymbosa var. hookeriana C. K. Schneid.) and distribution as Himalaya (Nepal to Bhutan), N. Assam, S. Tibet, N. Burma, W. China.
Our plants, I think closer to Deutzia staminea as per comparative illustrations from Flora of China:
Leaves are grey-tomentose underneath in D. staminea, green here. 
Moreover leaves are never more than 4.5 cm long in D. staminea, here they are much longer.

Calyx is quite different between the two as per comparative illustrations from Flora of China:
Pl. show it clearly. Matter will be decided accordingly.
