The small alpine Potentilla described as Potentilla sibbaldii Haller.f. in Flora of British India has gone either as Sibbaldia procumbens var. procumbens (eFlora Pakistan; eFlora China) or S. cuneata Hornem ex Kuntze. The Plant list treats P. sibbaldii described in FBI (synonym of Sibbaldia parviflora Willd.) as distinct from P. sibbaldii of Haller.f. (synonym of S. procumbens)

We thus have three plants to account for, luckily two are described in eFlora of China.
Sibbaldia cuneata: Stems erect or ascending, epicalyx equalling calyx; petals equalling or longer than calyx
Sibbaldia procumbens var. procumbens: Stems prostrate or ascending; epicalyx much shorter than calyx; petals shorter than sepals.
Sibbaldia parviflora: Much like S. procumbens but densely downy and appearing Grey

There are two plants uploaded in our database. One by me as S. procumbens var. procumbens. This should be S. cuneataefi thread
The second by … uploaded as Sibbaldia cuneata should be S. parviflora- efi thread
… has perhaps correctly identified his plant as S. parvifloraefi thread

Sibbaldia cuneata Schouw ex Kunze
Many thanks to … for the ID in my earlier post.

at Valley of Flowers on August 2, 2012


id is correct.


Should be better identified as S. parviflora

notice petals shorter than calyx, epicalyx shorter than calyx and spreading hairy flowers especially calyx


Many thanks … for this validation; will soon correct my notes at flickr.


Habitat: growing on rock
Habit: small herb, about 15 – 40 cm high; flower about 3 – 4 mm across


Sibbaldia cuneata I hope


Now correctly known as Sibbaldia procumbens


Many thanks …
At The Plants List, found these are being treated as separate species: Sibbaldia procumbens L. and Sibbaldia cuneata Hornem. ex Kuntze


It would be interesting to resolve this mystery. Flora of British India records Potentilla sibbalii Hallier.f with following synonyms:
1. Potentilla sibbaldii Clairv
2. Potentilla sibbaldia Greiss.
3. Sibbaldia procumbens L.
4. Sibbaldia parviflora Willd.
5. Sibbaldia cuneata Edgew.
6. Sibbaldia cuneata Kunze
As it seems these are now considered under two species
1. Sibbaldia procumbens L. with synonyms Potentilla sibbaldia Greiss. , Potentilla sibbaldii Hallier.f.,
2. Sibbaldia cuneata Hornem ex Kunze
(Sibbaldia parviflora Willd. unresolved and Sibbaldia cuneata Edgew. not mentioned (in Fl. China or the Plant List) except as synonym of S. procumbens in Flora of Pakistan
Both species are described in Flora of China and differ as under:
S. procumbens: Petals shorter than sepals; floweringt stems prostrate or ascending, 4-30 cm tall; petiole pilose; flowers 4-6 mm in diam.
S. cuneata: Petals equal or longer than sepals; flowering stems erect or ascending; 5-14 cm tall; petiole appressed pilose; flowers 5–7 mm in diam.
Perhaps close up of flower can help resolve.


Thank you very much … for digging into these Sibbaldia.
Attaching cropped pictures showing out-of-focus area.
My recollection:
Could see 2 plants with flowering stems ascending.
1) about 15 cm max.
2) about 30 – 40 cm
The flower about 4 mm; looks lesser than sepals in most of the instances.
I do not know about pilose OR appressed pilose petioles. Not sure if it can be made out in these views.

I had also uploaded same plant. The petals are longer than the sepals.


… I saw your upload at efi thread
To me, when I see them in profile view, most of them have the green sepals higher than the yellow petals.
Top views of the flowers give an illusion that the yellow petals are longer.
Will wait for comment(s).


This should be Sibbaldia cuneata Hornem. ex Kuntze
Sibbaldia parviflora Edgw. is a synonym.

Sibbaldia procumbens L. is not an Indian plant. The representation at Flora of Pakistan probably needs revision.


Who knows we may have both in Himalayas. The two plants uploaded cropped by … look definitely different, first suggestive of Sibbaldia cuneata and second with taller habit and shorter petals S. procumbens
Perhaps we need to keep our eyes open when we go to alpine Himalayas ne
xt time, important in light of confusion in literature.


Many thanks for your clarification regarding possibility of both species distributed in the Himalaya.
I may have not properly expressed when I wrote:
……………….
Could see 2 plants with flowering stems ascending.
1) about 15 cm max.
2) about 30 – 40 cm

……………….
Both these plants are seen on the same rock in the last photo, put here for quick look;

No … You only give me the idea and the proof.

Thanks…; will update my notes at flickr soon.

One of the commonest alpine plants.
