Dr. Sahab,
Your photographs are from UK, where only D. staminea and D. compacta
occur. In H.P., only D. staminea and D. corymbosa occur. According to
FLORA OF GARHWAL by GAUR, young branches are reddish brown in D.
compacta (also in your samples), while brownish in D. corymbosa.
Leaves are comparatively larger in size in D. corymbosa.

I think, your plant is rightly identified and my plant is different.




FROM FLORA OF CHINA
(They do not have D. corymbosa)

Oh! Got another hint in PLANTS OF KEDARNATH WILDLIFE SANCTUARY,
WESTERN HIMALAYA by Rai, Singh and Rawat.
Leaf base rounded or broadly cuneate in D. compacta.

Hi, Anil ji,

Your images look similar to those at Deutzia staminea R.Br. ex Wall. 

What are the keys ?

Deutzia corymbosa R. Br. is a syn. of Deutzia hookeriana (Schneid.) Airy Shaw as per Catalogue of life.

Details available in Flora of China and FoC illustration.

Checklist of Nepal gives Deutzia hookeriana (C. K. Schneid.) Airy Shaw as a syn. of Deutzia compacta Craib

Both these are closely related as per keys in Flora of China:

9 (8)	Leaf blade abaxially sparsely 6-8-rayed stellate hairy, hairs of 2 types (minute and larger ones)		7 D. compacta
+	Leaf blade abaxially densely 8-10(-15)-rayed stellate hairy, hairs uniform		8 D. hookeriana

Calyx is different in D.compacta as per FoC illustration and appears different from your post, to me.

Surprisingly, I do not find any stellate hairs on abaxial surface in your image DSCN0168.JPG (in fact, it appears totally glabrous)

No, Sir 

These are quite different from D. staminea.

D. staminea is very common species in H.P. and U.K. 

Thus one very rare. Seen only 2-3 plants during the last 10 years. It is similar to D. compacta occurring in UK and Nepal. 

D. compacta was enlisted at FoI. But, when I sent D. corymbosa to Dr. Tabish ji, he changed the correctly identified D. compacta to D. corymbosa. 

Kindly go through the complete thread. There is no error in my ID.

Garg ji
I am following Local Floras (Flora Simlensis, Flora of Sirmaur, Flora
of Kullu, Flora of Chamba, Flora of Bashahar Himalaya, Flora of Lahul)
along with POWO and WFO at present. I do not use Catalogue of Life.
POWO as well as WFO consider these three species (Deutzia hookeriana
(C.K.Schneid.) Airy Shaw, Deutzia corymbosa R.Br. ex G.Don and Deutzia
compacta Craib) as separate and accepted species. Deutzia staminea is
quite different from these.

Thanks, Anil ji.
You can clearly see calyx teeth is acute here and not obtuse as given in the keys for D.corymbosa. I think this is the most important character.

With regards,
J. M. Garg

[J.M. Garg]

For your posted plant, I will go for Deutzia staminea R.Br. ex Wall.

For your posted plant, I will go for Deutzia staminea R.Br. ex Wall. (where calyx is clearly seen).

With regards,

[Dr. Anil Kumar Thakur]

Kindly see the leaf characteristics, leaf size, abaxial surface and
inflorescence type.
I have no confusion between D. staminea and D, corymbosa. However, due
to nomenclatural changes, status of D. compacta, D. hookeriana and D.
corymbosa may change as they are more similar to each others.

Have you seen my another post on D. staminea?
Attaching information from FLORA OF KULLU which says calyx lobes
ovate/obtuse as seen in this case.

Yes, Garg ji
Calyx teeth acute in the key is confusing. However, they look entirely
different from each other. Leaves are large in D. corymbosa with green
lower surface (Grey in D. staminea). Inflorescence is terminal
(axillary panicles in D. staminea).
