These tiny flowers cover the wet floor of our slopes here. Is this some sort of a sandwort? Please advise.

Oldenlandia sp.

Thank you … for pointing me in the right direction. I will check what Col. Collett has to say about the Oldenlandia species here.

Col. Collett described two species with white flowers (no illustrations unfortunately): O. corymbosa and O. crystallina. The description is quite similar but for corymbosa he says ‘Capsule globose, not ribbed’ and for crystallina ‘Capsule bell-shaped, prominently ribbed’. When will the capsule develop?

efi pages on Oldenlandia corymbosa
Oldenlandia crystallina Roxb. is a synonym of Oldenlandia pumila (L.f.) DC. as per The Plant List.

The specimen looks different from my collection of O.corymbosa; 1.the leaves and calyx are scabrid, peduncle and pedicel slender and longer than this one; the capsule is globose and and not ribbed. So it may not be O.corymbosa.

Oldenlandia species.  But unable to pin point the species.

while I do appreciate your photographs and write up in the threads I come across, please don’t mind, I need more information and larger images at various angles of different parts of a critical species to arrive at a probable id.
Oldenlandia, Hedyotis and Neanotis are very difficult to identify can be reflected in many of our earlier threads in the group. Because, authors across countries, I think, have varied views on herbaria and literatures of British era; a fact can be seen/read in FoC or other sites.
However, you may try Neanotis hirsuta (L.f.) W.H. Lewis.

Thank you very much … once again. I will be happy to photograph the features you require to see. Please let me know what I need to do and I will get them in a day or two. Neanotis hirsuta looks very likely too.

Attached here the entry in Flora of British India. I would like to see if stipules have long bristle as had been described in FBI, if stems are rooting below. Also would like know if leaves, flower conform to size mentioned in the same record or in FoC –

It may not, as per eflora china tha calyx lobes is given as 1-2mm, linear lanceolate; corolla 3-4mm – which means corolla sholud be 3 times larger than calyx, but in your specimen calyx corolla ratio is not similar. stipules are not clear, try for another; very difficult to differentiate the three

Unless we have BSI KEy or at least checklist it is very difficult. While I suggested to check probability of Neanotis hirsuta (L.f.) W.H. Lewis. it would be better if we consider the following entities which FBI considered may be synonymous –

The pics in the link above suggest calyx is not problem area. Attached here KEY by Haines and Prain. Certainly, besides calyx we will have to take care of other aspects of this specimen.

Here we go. I hope I have remembered to photograph the features we required for a positive ID. The scale is cm/mm. 6 images.

Thank you … I have uploaded additional images in the same thread.

Thanks a lot …
I would not upload old literature I have. FBI-FI-BP-BoBO certainly not enough to determine this species. We need book like “Taxonomic Revision Of Hedyotis L.(Rubiaceae) In Indian Subcontinent / Dutta & Deb.”
This species is none of the corymbosa, crystallina & hirsuta.
For corymbosa (also paniculata) following links may be consulted-
Since flowers have very conspicuous pedicels hirsuta is also ruled out though FBI says flowers are pedicellate.
This is probably Neanotis calycina (Wall. ex Hook. f.) W.H.Lewis. Please check FoC and attached doc. Please note calyx in your specimen looks a little longer/larger but that maybe due to onset of fruiting.

Thank you very much … for your detailed analysis and the time you have devoted in exploring this. I am truly grateful. I will read all the papers/sources  carefully once I return from my travels. In the meantime, after a quick read of the pdf and seeing the pictures, it looks very likely that our sample is N. calycina.


Neanotis calycina ABSEP2016/02 : 5 posts by 3 authors. 4 images.
These Neanotis plants have been around for a couple of week and I had been meaning to share some photos. Surajit last year had worked hard to nail this ID.

another candidate for your white background pics. this is nice too
but many places are not in focus

Thank you …. Out of focus areas—a character of using a macro lens in the field. I don’t use a tripod to be flexible with my angles and light in the mountains is never enough for a small aperture.

Seen this small Herb ( 6 to 8cm in height) en-route Raigad on the wet rock.
Flowers small in size (approx. 4 to 5mm).

It is Neanotis species…..can be N. paniculata.

Neanotis species so far in efi 

I think closer to Neanotis calycina (Wall. ex Hook.f.) W.H.Lewis as per images, details and references herein.

Neanotis sp. ???

Oldenlandia biflora

Thanks, … Looks different from Leptopetalum biflorum
I think same as another recent post by … i.e. Neanotis calycina

I also think different. Any further suggestion … ?

Don’t you agree with Neanotis calycina ?

Looks matching !

Rubiaceae Week: Small Rubiaceae? herb from Chakrata Area:

Pls id this small wild herb shot from Chakrata Area
Looks like any Oldenlandia sp
pls id

Could this be a species of Oldenlandia : possibly Oldenlandia diffusa?

Interesting plant….would love to know the id.
If the leaves are not hairy, I would have guessed for Hedyotis biflora (= Thecagonum biflorum) due to similar fruits.

Hedyiotis / Neanotis ??
What are the sp. listed there ?

I think it appears close to Neanotis calycina (Wall. ex Hook.f.) W.H.Lewis
Flora of China says:
Leaves subsessile or petiolate; petiole to 3 mm, glabrous; blade drying papery, lanceolate to ovate-lanceolate or lanceolate-elliptic, 1-3.5 × 0.5-1.5 cm, adaxially sparsely scaberulous to puberulent, abaxially glabrous or puberulent to scaberulous on principal veins, base cuneate to acute, margins ciliate to scaberulous, apex acute to acuminate; secondary veins 3 or 4 pairs;

I support the ID by …
