  • Lepidium
.
Bitter Cress, Lesser Swinecress, Wart cress • Hindi: Jangli hala;
.
Spreading annual herb, branched from base, bad smelling; basal leaves pinatisect 5-10 cm long, with numerous small segments, upper sessile with fewer segments; flowers minute, 1-1.3 mm across, in shot compact raceme elongatng in fruit; petals minute or absent; stamen 2; silicula didymus, broader than long, 2.5 mm broad, with globose valves with one seed in each.

It (Soliva anthemifolia) might be easily confused with Coronopus didymus (now Lepidium didymum L.) but the flowers occur in sessile axillary capitula hidden at the base of leaves. If you find a Coronopus like plant whose leaves also remind you of an umbellifer, look for the greenish sessile (brownish when dry and mature) capitala. It could be Soliva anthemifolia

Coronopus didymus,

 
Is This Lepidium didymum ?: 9 images.
Am attaching  photos of a plant which I think is Lepidium didymum. All photos were taken in second half of April 2023. The habitat is the side of a path in Srinagar, It has four sepals two tiny stamens with flat lower ends (1 mm long) and a large ovary with a very short style. Petals are absent. Small squares in all photos except photo 3 are 1 square mm. In photo 3 small squares are not visible and visible squares are of 5 sq mm area.
An interesting puzzle
I would like to draw attention to an interesting puzzle regarding this plant, I found the pollen grains to be elliptical or spindle shaped (Fusiform) (See Photo 8 and 9) but a google search shows the pollen grains of this plant  to be somewhat globose. Based on pollen morphology is our Himalayan plant a different subspecies of the European plant ? The Botany Departments of Universities in Himalayan states may like to investigate it further.

ID looks good !

Beautiful pictures of the commonest weed.

What puzzles me is the fusifòrm pollen grains that I saw and photographed.
Of course I depended on Google search for comparison which might have misled me

In photo 3 the visible squares are 25 sq mm in area and not 5mm as written.
Correction is requested

Two more photos of fusiform pollen grains:
Photo 1 X200
Photo2 X200 (Dark Field )

Yes, appears close to images at
https://efloraofindia.com/2011/02/19/coronopus-didymus/

Having examined the pollen grains of another crucifer I find that fusiform pollen grains are usual for cruciferae. I was misled by some images on google search to think that they are unusual.
