Please visit the link - and you will see key to differentiate at least three species. 
My species has leaf size of Euphorbia heyneana Spreng. But FoC says leaf base is extremely oblique in E. heyneana. How much is "extremely"?
... identified another plant as Euphorbia serpens Kunth -
Fl. Br. Ind. describes both the species under E. microphylla Heyne. Bengal Plants has no "serpens".
I think my species is Euphorbia serpens Kunth because of its stipules, even if leaf-size is more close to Euphorbia heyneana Spreng.
The Bengali name CHOTO KERUI (ছোট কেরই) for "microphylla".
I, in my area, have identified it as E.heyneana

Tiny herb growing between the garden tiles in our home garden at Nasik.
Yes, it is Euphorbia heyneana Spreng.

Small Herb for ID : Euphorbia : Nasik : 121212 : AK-3: Very tiny herb growing wild in the garden between cracks in the cement tiles.
Euphobria species.
Id please.
This is Euphorbia heyneana.
EUPHORBIACEAE FORTNIGHT: Euphorbia heyneana Spreng. from Uttarakhand_DSR_16 : Attachments (1). 4 posts by 4 authors.
Euphorbia heyneana Spreng. is a prostrate spreading herb often found along roads and trails in Pantnagar.
Thanks ... for sharing. First time observing this (Even first time during the fortnight)
Some species are very confusing..I am scared to start uploading them due to probable mixing up, still, will try to sort out...
Thanks ..., this seems to be in my collection...
Fwd: Euphoribia orbiculata :
pl find attached E orbiculata. profusely spread on tank boundary after rain and is in flower.
Correct me if I am wrong
As per The Plant List, there are two plants with this name. If correct which one?

Noticed this small herb beside our kitchen drainage. There are 3 or 4 individual of this species, each having around 3 to 4 cm length. Unfortunately the other camera I have is now out-of-order!
I regret bad picture quality, but the plant itself has tiny flower and fruit. The features are, as far as I can make out of the attached photographs, (i) opposite sub-sessile leaves (ii) leaves are about 5mm in length (iii) leaf apex serrate.
Any probability?
From the photographs it appears that the plant is erect and ascending and not prostrate or procumbent. Please confirm this point. We will soon comment on it.  I am awaiting reply of ...
In the mean time please take good photographs, collect a sample and press and dry it up in a news paper or blotter in such a manner that both surfaces of the leaves are visible.
Today I have photographed a few shot of the species again, one or two individual, each within 3 cm height is erect as can be seen in the first photograph. But the community (my assumption, I didn't disturb the herb) is decumbent aqs can be seen in the 2nd image.
I also attach herewith cropped part of two original pictures for the highest detail my camera could take.
The herb is growing in sandy soil, produced by debris of building materials like sand, concrete dust, small gravels etc. But the place is always damp.

Please check whether it can be a form with stunted growth.
Your link leads on to Euphorbia cristata which it is not and the same has not been recorded from West Bengal so far.
I can not think of any other genus.
I was also thinking of stunted growth, a stunted form of Euphorbia thymifolia L.?  ... threads are so different looking. that I thought it must be some other species.
In fact I failed to find any particular feature in my photographs. Instead, I searched matching images and discarded E. granulata, came across the similar looking image of E. cristata in 'indiabiodiversity' site!
This small herb seems to be interesting.  It is closely related to Euphorbia serpens, differing in the serrate margins of leaves, rounded to obtuse (rather than retuse) at apex. I do not see the root primordia at the nodes which are usually present in E. serpens. Further differences, if any, can be ascertained by examining the flowers and fruits under a microscope.
Superficially similar to E. cristata in its foliage but the whole plant (habit) is much smaller. with smaller, glabrous leaves, trinerved at base.
Further critical studies are therefore very desirable to establish its status.
I do not have a simple microscope, have a compound one but do not know how to examine an entire flower under it. I will try to examine for more features with a magnifying glass and would inform you if I find any.
I request you to please examine and identify one my old thread of a different species.
Thank you very much. It is always a learning session under your guidance.
You need a binocular dissecting microscope.
The other thread is giving the identity of Euphorbia heyneana subsp. heyneana (syn. E. micorphylla B.Heyne ex Roth). Your present plant is even closer to that but in that case the habit is prostrate and a cyathial stalk present. Here I see clearly ascending or erect habit and no cyathial stalk is visible.
Yes, Sir, this species (in this thread) is ascending or erect. The problem is cyathium is so small that my camera fails to produce detail. Since it is the flowering time of this species I will try to find it somewhere else so that we can conclude that it is a stunted or deformed state of a certain species.
For the time being, the following name may be assigned to it, although I am not satisfied but without further details it is impossible to clarify its status:
Euphorbia heyneana Spreng. subsp. nilagirica (Miq.) Panigrahi which has erect or or ascending habit and the same is an endangered endemic confined to the Nilgiri hills of Tamil Nadu.
Thank you Sir. One earlier thread by Aarti Ji looks somewhat similar to species. Presently I mark it with E. heyneana.
This plant is definitely E. granulata Forssk. In this species leaves are sometimes serrulate and root primordia are sometimes not developed. It does fit into any other species.
I am grateful to you and ...
Based on the webpage I am trying to understand Euphorbia inflorescence. I am attaching a plate of this species. I can understand which one is capsule. Both Flora of China and Pakistan inform that in this species cyathium is single. Then what are those red-marked structures shown in the plate?
Attachments (1)
Those red-marked structures appear to be glands of the involucre cup.
Thank you very much Sir. It appears to me that these glands do not have appendages, or if present appendages are very minute. Flora of British India recorded, "glands usually without a limb." It means limb of a gland is same as appendage of a gland. Please correct me if I am wrong.
In cyathia of Euphorbia, the glands sometimes do not have appendages (also called limbs by earlier authors).
Sometimes they are very minute. In most species of subgenus Chamaesyce the appendages are distinct, prominent and petaloid.

I am very grateful to you for taking patience and care of my queries. I look forward to learn more on this family from you and ... in near future.

Forgive me sir, but I must respectfully disagree that this is E. granulata. Note that the fruits are partially included within the cyathia at maturity. This is the classic distinguishing characteristic of E. thymifolia. The fruits of E. granulata are well exerted at maturity. Furthermore, all the material of E. granulata I have seen have hairs that are straight and spreading, not appressed as in E. thymifolia.
Just to clarify, this also includes fruits that appear exerted but come out near the base of the cyathium as in the case of the close-ups. Some more typical examples can be seen in the cyathia on the right branch in the second photo. The important characteristic is actually the length of the gynophore, which typically manifests itself by being partially included at maturity. Sometimes the fruits do manage to escape from the involucre, but it is only by growing through a deep cyathial sinus on the side of the involucre making the fruit base appear as if it is adhered perpendicularly to the side of the cyathium rather than coming out the apex or curving through a relatively shallow cyathial sinus such that the fruit is either parallel or at an acute angle to the cyathium.

This appears to be Euphorbia heyneana Spreng (syn.: E. microphylla B.Heyne ex Roth, non Lam.), common in wet grasslands throughout India.
