as per Catalogue of Life;

Annual herbs about 8-20 cm tall, laxly caespitose, stem much branched dichotomously, procumbent, pubescent with line of white hairs on single side, roots robust hard and long. Leaves simple, opposite, obovate-elliptic to lanceolate, about 6-15 x 3-6 mm across, base cuneate, margin ciliate, apex obtuse with mucronate tip, glabrous, gland dotted, dark green above and paler beneath, midrib impressed above and prominent beneath, lateral veins absent on both sides, petiole subsessile, exstipulate. Inflorescence in axillary or terminal, few or many flowered. Flowers bisexual, actinomorphic, about 3-4 mm across, pedicel slender, viscid pubescent, about 10 mm long, bracts linear lanceolate, foliaceous, apex acute, about 5 mm long, sepals 5, free, lanceolate-ovate, 1-veined, base broad, margin scarious, apex acute, pubescent with white hairs above, about 3 mm long, petals 5, free, white, linear obovate, equal or slightly longer than the sepals, margin entire or lacerate, apex obtuse. Stamens 10, usually in 2 series, filaments free, filiform, shorter than sepals, those opposite to sepals are glandular and thickened at the base, anthers 2-locular, dorsifixed. Ovary superior, unilocular, ovoid, about 0.8 mm across, ovules many, free central placentation, styles 3-4, filiform. Fruit capsule, obovoid-globose, 6 valved, almost as long the persistent sepals. Seeds subobovoid to reniform, compressed, striate transversely.

Looks to be from Caryophyllaceae… any Arenaria?

Arenaria serpyllifolia L. ??


Not Arenaria serpyllifolia L. as per images herein. Pl. check with images at Arenaria orbiculata Royle ex Edgew. & Hook.f. 


According to the images the positioning of leaves (distance between two leaves) are very far and looks like matching with Arenaria serpyllifolia L.
Just my observation.


Check the relative size of sepals and petals along with hairyness and apex of the leaves. I think these are quite different. 


As it appears closer to images at Arenaria serpyllifolia L. (Sepals 3.5-4 mm, lanceolate, acute to acuminate, scabrid, ± glandular or glabrous, margin scarious, usually 3-veined. Petals white, less than the length of the sepals. Capsule exceeding the sepals …), but sepals are shorter than petals. I looked at keys in Flora of Pakistan, where another closer species was Arenaria leptoclados (Similar to Arenaria serpyllifolia but leaves obovate to spathulate, especially lower ones, usually mucronulate; sepals 2.5-3 mm. lanceolate, exceeding capsule, the calyx gradually narrowing above, not thickened at the base).

Flora of Pakistan says Arenaria serpyllifolia is very similar to the following 3 species (I think Arenaria orbiculata, Arenaria neelgerrensis & Arenaria leptoclados) described next and often difficult to separate satisfactorily. Variable in its vegetative characters, especially the indument. A. serpyllilfolia is a tetraploid (2n=40) and probably derived from A. leptoclados (a diploid) and another closely related species (McNeill, l.c. 1967).


…, according to the book Fora of Mustang Arenaria serpyllifolia L. is not listed.

Out of listed 9 species I guess Arenaria neelgherrensis Wight & Arn matches to the closest.
Your opinion please !


Arenaria orbiculata Royle ex Edgew. & Hook.f. as well not listed and does not look matching!


I did not get your stated keys ?

Yes. appears so.

Pl. check comparative images at Caryophyllaceae 


Arenaria ??

I think Arenaria serpilifolia is Correct, …


yes morphology, habitat and elevation suggests it to be Caryophyllaceae

Arenaria serpyllifolia L.   


Thank you … However, this sp. is not mentioned in the book. 

May be many sp. left out. Even Gesneriaceae is not mentioned in the book.


Yes …

In coming days we must cover the remaining from that area.


On your shoulder! 


Hope to be part of that.


But this species (Arenaria serpyllifolia L.) has not been mentioned in the Flora of Mustang as post at SK597 26 JUN-2017:ID
It has been taken on the same date as well.


Thank you … I guess the ID is correct!
