Beautiful photographs as usual. The plant reminds me of Prof. BGL
Swamy who used to bring this plant, Bacopa munneri, Ammania buccifera
etc for the M.Sc examinations in 70,s

Garg ji

This needs to be resolved.

If Chrozophora plicata (Vahl) A. Juss., 1826 (basionym Croton plicatus Vahl, 1790) and C. rottleri (Geiseler) A. Juss., 1826 (based on Croton rottleri Geiseler, 1807) are synonyms, the former should be the correct name as it is based in earlier basionym.

If two are distinct species as listed on the Plant List, we have to know the differences to choose our plants from North India and Western Ghats.

I hope Tapas ji and Balakrishnan ji can throw better light on this based on their treatment of Indian Euphorbiaceae.

Thanks a lot Balakrishnan ji for clarification

based on Reply from Balakrishnan ji 

"The real Chrozophora plicata (Vahl) A.Juss. ex Spreng. does not occur in India. It is confined to Africa and Middle East. What is given  as C. plicata in Indian floras are now known as Chrozophora rottleri (Geisl.) A.Juss. ex Spreng.

Forwarding for ID

Distributed as  Chrozophora rottleri

I strongly feel that it is C. plicata, whether we follow Flora of Malesia

Chrozophora (nationaalherbarium.nl)

or follow key given by Tapas ji

Plants are prostrate (not erect), smaller (less than 3 cm, not larger), plicate , dark green (not light green), stigma orange (not red), fruit with spreading hairs (not flat)

Yes, Chrozophora plicata.

[J.M. Garg]

I think there is some confusion here.

Flora Malesian gives the following difference (It also does not have Chrozophora plicata (Vahl) A.Juss. ex Spreng. (like India as per Balakrishnan ji)):

Chrozophora plicata (Vahl) A.Juss. ex Spreng. is often confused with C. rottleri, because one of the first leads in Prain’s key (1918) asks for the length of the inflorescence relative to the surrounding leaves. The inflorescence should be shorter than the leaves in C. plicata and longer in C. rottleri. However, they are only longer in C. rottleri when the inflorescences are old and have shed their seeds. The best character to separate both species is in the stellate hairs on the ovary/fruit, these hairs are flat, 2-dimensional, almost lepidote in C. rottleri (lacking the patent hairs), and normal, 3-dimensional in C. plicata. Furthermore, the leaf blades in C. plicata are usually smaller (less than 3 cm long) and of a much darker green (at least when dry).

It also gives Staminate flowers 4–6 mm in diam., yellow; calyx white, united part c. 1 mm high, lobes 3.2–4 by c. 1.2 mm; petals 3.7–3.8 by 1.5–1.6 mm; androphore 3.3–3.8 mm long, basal 1.2–1.3 mm without filaments; filaments 0.3–0.8 mm long; anthers 0.9–1.3 by c. 0.7 mm, yellow. 

I can not see the nature of hairs from the low res. image, as per differences above. However, the stigma is yellow here as given for C.rottelri in Flora Malenesia.

Earlier Balakrishnan ji has stated:

"The real Chrozophora plicata (Vahl) A.Juss. ex Spreng. does not occur in India. It is confined to Africa and the Middle East. What is given as C. plicata in Indian floras are now known as Chrozophora rottleri (Geisl.) A.Juss. ex Spreng.

[J.M. Garg]

I see stigma to be yellow only as per other observations at C.rottleri

I find that as per keys provided by Tapas ji in this post, C.prostrata is now given as syn. of Chrozophora plicata (Vahl) A.Juss. ex Spreng. as per WCSP. So if this is correct, C.prostrata is now given as syn. of Chrozophora plicata (Vahl) A.Juss. ex Spreng. is very much available in India and Singh ji plant may very well be this one.
