(From India Biodiversity Portal (Pilea microphylla (L.) Liebm.) 

Pilea microphylla also known as Artillery Plant, Gunpowder Plant or (in Latin America)[2] brilhantina is an annual plant native to Florida.[3]

The plant belongs to the Urticaceae family.[4] It has light green, almost succulent, stems and tiny 1/8″ leaves which contribute to its other nickname, “Artillery Fern”, though it is not related to ferns. It is grown as a ground cover in many areas.
Pilea microphylla can be propagated by dividing the root ball, or taking herbaceous cuttings and rooting them with rooting hormone. The plant enjoys a thorough watering after the soil has been allowed to dry, and misting has been shown to be beneficial. Direct sunlight causes the leaves to turn brown and fall off, so it prefers filtered light.

An ornamental, potted plant with very tiny leaves seen at Lalbagh on 18/3/13.
… our ornamental expert has suggested Pilea depressa.
For id confirmation please.

Pilea sps. for sure. Please also check for P. serpyllacea.

Pilea serpyllacea does seem to match with my plant.
Common names are Artillery Plant, Gunpowder Plant.


Please ID this tiny herb / weed in garden : GE-May2015-1/1 : 4 posts by 3 authors. 2 images.
The leaves are about 3mm x 1mm, to 6mmx2mm flowers less than 1.5 mm, the stalked inflorescence is of a few cymules
(The white flower in 2nd image is of a different plant)
Please help with ID

Pilea microphylla. Urticaceae

Agree with … It is P.microphylla. A weedy plant but cultivated also for its foliage.
White flowers in second picture may be of Mollugo sp. (Molluginaceae).

Thanks ! i would have never found this id, and it is my first intro. to Uriticaceae.
Pilea microphylla (Artillery plant) it is, matches exactly with FOI images and description from IFAS Univ of Florida. Which also explains the unexpected common name for such a small plant
A multitude of minute, lime green leaves on short, arching stems gives artillery plant a fine-textured, fernlike appearance (Fig. 1). Growing only 8 to 12 inches tall and quickly forming spreading clumps up to two feet wide, artillery plant makes an attractive tropical ground cover. The common name is derived from the forcefully ejected pollen from the rather inconspicuous flowers on this brittle and succulent plant.”
Wondering if this could be one of the tiniest flowering plants ever.


August2015sk04/04 — unknown small herb on wall : 4 posts by 2 authors. Attachments (5)
I was in a very tight schedule during the past two weeks or so. About a fortnight ago I went to Hooghly Sadar, a historical place.
I noticed a small herb growing on walls of buildings there. Also on rubbish. Those which grew on walls, I think, are not stunted as it may appear (given their habitat). I didn’t have ruler neither camera. All pics recorded on galaxy-duos.

Well, possibly Pilea microphylla Liebm.

Yes, most probably Pilea microphylla..

August2015sk05/05 — another unknown herb on wall and rubbish : 3 posts by 2 authors. Attachments (3)
This is another one, more or less same size, or even smaller, as in efi thread. Even maybe same species. I am not sure. I have only these three images (also have originals). The first images is cropped original.

Yes, this also looks to be Pilea microphylla ..

Yes, Sir, this was also looks same species. Thank you.

Please help me with the name of this flower.
Close to Trivandrum Kerala
2. Growing on shady walls and drain walls
3. Looks like Pilea microphylla superficially
4. Tiny plant around 4″ with small pink flowers

Are you sure the pink flowers belong to this herb only and are not shed by any nearby high herb/shrub? To me also this herb is closer to Pilea, which should not have such flowers..!!

Agree with … thoughts. Perhaps the fallen flowers (florets) belong to Lantana (not sure).

Again old pictures of mine which I came across while checking some folders.
Very tiny wild herb.
Could be Pilea Species?

Pilea species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available on net)

…, looks like Pilea to me too.

To me appears close to images at Pilea microphylla (L.) Liebm. 

I too agreed with P. microphylla …
