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) http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=109728 http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=241000484 http://www.efloras.org/object_page.aspx?object_id=12445&flora_id=2 On 8/3/20, Dr. Anil Kumar Thakur <[email protected]> wrote: > Deutzia corymbosa > Shimla > May 2018 > > -- > With best Regards, > > Dr. Anil Kumar Thakur > -- With best Regards, Dr. Anil Kumar Thakur -- You received this message because you are subscribed to the Google Groups "efloraofindia" group.
