You had asked for the list of Rhodiola sp. in H.P. I am attaching complete list of plants recorded from H.P. and published in Flora of Himachal Pradesh by Botanical Survey of India.
As Rhodiola genus was part of Sedum earlier, the various species are listed under Sedum.
I’ll try to reorganise the species later on.
I have updated eFI (efloraofindia) page on Rhodiola Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links. Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details. If someone can provide complete list of Indian species with source references it will be wonderful. Any comments/ corrections are welcome. . Rhodiola (Crassulaceae) page with images of species in efloraofindia : 8 posts by 3 authors. Pl. go through Rhodiola (Crassulaceae) page with images of species in efloraofindia. If you find any incorrect identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), if any, it will be really nice. Have you discontinued to show the names of contributors on species pages? Yes, …, for the time being, as putting images on all species, genera & family pages appears very daunting.
Instead some of us are putting images just above the threads as you can see at Rhodiola heterodonta, so that these are indirectly linked to the threads.
However, members who are inserting images can follow what ever they like. Thank you, … Even this is looking good. Thanks, …, for the understanding. As I have just stated, I am working on Rhodiolas of Ladakh (and surrounding regions) but am not yet ready to face commenting on all the Rhodiola entries for efi.
Hopefully, will be in a position to do so in the future. .
