This one was just above Triund. I think this is V. serpyllifolia. Please advise. Veronica serpyllifolia. Triund, 2850m approx., 03-04 May 2017

Could this plant shared by me in 2017 be V. serpyllifolia ssp. humifusa?
I am asking because I recently found a smaller and whiter version of this species at 1800m which I suspect to be ssp. serpyllifolia. Please advise.


I got the keys from Scrophulariaceae of the Western Himalayas By Francis & Pennell.
I also got the keys as below from Go Botany:
1a.  Corolla blue, 5–8 (–10) mm wide; pubescence of pedicels, in part, of viscid or glandular hairs; filaments 2–4 mm long; racemes with 8–15 flowers; larger capsules 4–6 mm wide 
 … 17a. V. serpyllifolia ssp. humifusa (Dickson) Syme
1b.  Corolla pale blue with blue lines, 2–4 (–6) mm wide; pedicels puberulent with eglandular hairs; filaments 1–2.5 mm long; racemes with (12–) 20–40 flowers; capsules 3–4 mm wide 
 … 17b. V. serpyllifolia ssp. serpyllifolia
Pl. check.


Thank you very much … I had seen the Go Botany keys but was wondering ion a member had first hand experience of the subspecies. I will file the other ssp. Soon.


On checking with keys from both the sources lead me to V. serpyllifolia ssp. humifusa (Dickson) Syme


But what is worrying me is that Catalogue of Life does not give its distribution in India.
Although Conspectus of the genus Veronica Linnaeus (Plantaginaceae) in India by Priyanka Agnihotri, Veena Dixit and Tariq Husain – Pleione 8(1): 9 – 16. 2014, gives its distribution in Uttarakhand only as below:
V. serpyllifolia Linnaeus, subsp. serpyllifolia 2400 – 4000 May – August- J&K, UK, HP, WB- Afghanistan, Europe, Australia, China, Japan, Africa, N. & S. America
V. serpyllifolia subsp. humifusa (Dickson ex Withering) Vahl 2100 – 4000 May – August- UK- Europe, Australia, N. & S. America, China, Japan, Russia

Thank you … Perhaps we have only one ssp. and there is good variation in plants growing at different elevations in the same area. Or perhaps a further study is required to establish the differences. I am posting a plant here for your reference.

While the plant I posted earlier is from above 2800m, the other included here is from 1800m. The flowers of the plant at the lower elevations are significantly smaller and whiter. The leaves too are smaller and smoother with no hint of hairiness. I am including them for your reference.

Thanks, …, for the superb presentation.
For your original images, I will go for V. serpyllifolia ssp. humifusa (Dickson) Syme only, as per keys.

No, it is different. Pl. check comparative images at genus page in efi site.


Ok. I will check.


Please check Veronica serpyllifolia subsp. humifusa (Dicks.) Syme !


Pl. send the high resolution image to check the details.

Here it is..

May be Veronica serpyllifolia subsp. humifusa (Dicks.) Syme although I do not clearly see pubescence of pedicels, in part, of viscid or glandular hairs, which differentiates it from Veronica serpyllifolia subsp. serpyllifolia 

Thanks … Another similar one was seen near Gulmarg, but couldn’t go closer.

So the picture is not clear.
