Please help me identifying the Euphorbiaceae herb – Euphorbia sp. attached herewith.
Habit: Herb, prostrate
Habitat: Road side waste land
Leaves: 1 to 1.5 cm, Elliptic – oblong, glabrous, rounded tip, minutely serrated to crenulate, petiole – 2 mm
Entire plant very leafy, glabrous.
Currently in flowering. Image taken on 9th April 2014
This appears to be E. pycnostegia Boiss. var. zornioides (Boiss.) Santapau, endemic to C.& Pen. India.
Thank you so much for identifying this. But I have few doubts.
The description given by Fr. Santapau on E.pycnostegia var.zorniodes in Flora of Khandala is as follows:
“Very similar to E.pycnostegia from which it is separated by smooth, non-tuberculate seeds. Leaves are opposite, but branches quite often are only produced in the axil of one of them; size of leaves upto 55×17 mm “
I had seen E.pycnostegia in field last year and it was an erect, stout 1 – 2 feet high plant.
While the plant in question is prostrate, small and spreading.
BSI Flora of Maharashtra has not included this var. zorniodes instead mentions E.zorniodes as a different species.
But the features given under this doesnt seem to match with my plant.
I can quiet understand your concerns on the identity of the species. It is necessary to have broader look at each species.
Herbaceous Euphorbia species growing in wet habitats, particularly the pycnostegia complex is very variable, depending on the ecological conditions, where they grow. Hence we cannot fix hard and fast parameters on their morphology. Each author describes them in different ways depending on their ecological environment. It is nor advisable to describe each as a separate variety, which would add only confusion and chaos; one has to take a broad outlook on the phenotypic plasticity to each species. Only a monographer, who has studied a large number of herbarium specimens from various localities can give a broad all-encompassing description.
Really grateful for clarifying my doubt! I will keep this under E.pycnostegia var. zornoides as suggested by you.

ID please. Is this some species of Euphorbia ?
Date: 02 OCT 2016
Place: along Khopoli Mangaon Road
Habit: erect slender branched herb with slender stem, about 60 – 70 cm high, tiny flowers just about 2 mm across
I was not able to get more photos due to incessant rain at the site. Will be happy to know the genus level ID if these photos suffice.
The genus seems to be okay.
This is Euphorbia pycnostegia Boiss. var. zornioides (Boiss.) Santapau, common in Maharashtra, Konkan, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu, usually in moist grasslands.
