Tiny white flowers ABAUG01/27 : 21 posts by 5 authors. 3 images.
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?

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.

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 – http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242413768.

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 –

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

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.

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.

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.

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 …

Looks different from images at Leptopetalum biflorum

It is Neanotis calycina, as per images and details herein.
