DV :: 31 JUL 12 – 0408 :: ¿ Lepidium ? at Tapovan near Joshimath: 3
1 JUL 12
Tapovan … about 6000 ft

Habitat: shrubbery on mountain slope
Habit: low herb

Yes, this is Lepidium sativum

To me fruits look much smaller and leaves much narrower than Lepidium sativum, and no emerging petals visible. Could you provide a close up of flower and fruit, and give idea about size of the fruit.

here are two photos (cropped versions). Hope they show to certain extent, what you are looking for.
I am not able to recollect the size aspects. In the first picture we see a small ant (about 3 mm long).

Thanks for the ant, which perhaps will help. The fruit seems to be shorter than ant, barely 2.5 mm or so, petals seemingly rudimentary and fruit with a small notch at tip: All pointing to Lepidium apetalum (syn; L. ruderale auct.).
In L. sativum petals are longer and fruit size more than 5 mm long.

Plant for ID :: Govindghat-Ghangria, Uttarakhand :: Aug 2018 :: ARKSEP-03 : 10 posts by 4 authors. Attachments (3)

Requested to please ID this plant found on the way from Govindghat to Ghangria, Uttarakhand in August 2018.

weed of brassicaceae. Thilaspi sp

Thank you so much … for the response. Based on the images in efi of the shape of the seeds, it seems to be Thlaspi arvense.

Brassicaceae ?

do you recall the size of the fruits?

I guess the size of fruits may be at most 4-5 mm.

Could this be Lepidium apetalum? I was going through … VOF posts. He has posted it here. The images look similar.

well its synonym. Thlaspi apetalum (Willd.) Poir. is a synonym of Lepidium apetalum Willd. per the plant list
http://www.theplantlist.org/tpl1.1/record/kew-2437667
i had typed the spelling wrong … a misplaced i above. you could go with either name

Thanks … for validating…

Earlier we had discussed this plant and it was concluded that this could be some Lipidium sp. Sharing this once again for ongoing Brassicaceae week.

… most probably Lepidium apetalum.

I guess it is matching however, habitat and leaf images would have helped more

Capsella bursa-pastoris? or may be other species of Capsella..

As … said this can be Capsella bursa-pastoris or any close species to the said plant.

I was also going to type that, till I saw notification of your mail, and this gave me time to think.
It is not Capsella, rather Thlaspi, the leaves are not clear (unlike … usual photographs) but short style and nearly orbicular fruits suggest T. arvense.
Capsella has a broad nearly triangular notch of fruit.

I stand corrected Sir Ji thanks for pointing out the difference

Thlaspi arvense only, from fruit and style. … how did you get confused about Capsella bursa-pastoris, the shepherd’s purse? Here it is

I got confused after seeing from the top view.

Thank you …, I was not attentive. This is not Capsella.

It looks like Lepidium to me, I may be wrong though.

Thlapsi arvense: illinoiswildflowers.info

… plant is not L. apetalum in which petals are rudimentary or absent and fruits hardly 2-2.5 mm. Please check my mails on Lepidium. The same plant of … is labelled at L. viginicum at FOI and L. apetalum at Flicker. That plant as already written by me is neither of these two. It is L. sativum.

efi thread 1

efi thread 2

Two things have been worrying me right from the begining the leaves (which are not focussed) and smaller plants, and in that respect (here … may be right): my plant on FOI as Lepidium sativum, … L. apetalum on Flicker and … L. virginicum on FOI are I think same plant, and it is Lepidium sativum.

Thanks … for the explanation. This will lead to some resolutions, I think.

Many thanks … for clarifying and correcting my plant’s ID.

May be Lepidium apetalum ? as per this thread.
