Cerastium glomeratum is a species of flowering plant in the pink family known by the common names sticky mouse-ear chickweed and clammy chickweed.

It is probably native to Eurasia but it is known on most continents as an introduced species. It grows in many types of habitat.
This is an annual herb growing from a slender taproot. It produces a branched, hairy stem up to 40 or 45 centimeters tall. The hairy leaves are up to 2 or 3 centimeters long. The inflorescence bears as few as 3 or as many as 50 small flowers. The flower has five hairy green sepals which are occasionally red-tipped, and five white two-lobed petals which are a few millimeters long and generally shorter than the sepals. Some flowers lack petals. The fruit is a capsule less than a centimeter long which is tipped with ten tiny teeth.

Panipat 2014: Cearstium fontanum for validation:: NS March 07 : 3 posts by 2 authors. Attachments (5).
This chickweed was shot from a nursery in Panipat
perhaps an introduced wild species, confined only to places where plants brought from other places are kept…
Please help to get exact id..
I took this as Cerastium fontanum based on earlier discussions..

please validate/correct the id.. very close looking species is Cerastium glomeratum..


Yes … It is clearly C. glomeratum on two counts.

Petals are longer than sepals (shorter in C. fontanum)

pedicels are shorter than capsule/flower (much longer in C. fontanum) and flowers appearing like glomerule (not so in C. fontanum).


Thanks a lot Sir, for such a quick and descriptive reply…

Cerastium fontanum


I think it will be Cerastium glomeratum as per discussions at Confusion between Cerastium fontanum subsp. vulgare and Cerastium glomeratum


Yes C. glomeratum

Caryophyllaceae Week: Cerastium fontanum subsp. fontanum from Kashmir: Cerastium fontanum Baum., Enum. Stirp. Transsilv. 1: 425. 1816.
Decumbent or erect annual herb ovate-lanceolate to oblong leaves, 1-3 cm long, hairy on both suraces; flowers white in spreading dichasial cymes, pedicel longer than sepals, recurved in fruit; sepals 5-6 mm long with membranous margin; petals obovate-oblong, slightly longer to almost 1.5 times as long as sepals, bilobed at tip; styles 5; capsule nearly twice as long a sepals, with 10 recurved teeth.
A very common species at lower as well as higher altitudes in Kashmir.

Cerastium fontanum ABMAR01/07 : 5 posts by 3 authors. 7 images.
Cearstium (ser-ASS-tium) comes from Greek keras, a horn, and refers to the horned shape of the seed capsule. The flowers are very similar to Stellaria (Latin Stella: a star) in shape, colour and size. The leaves are stalk less and tear-shaped with more downy hair. The brown papery capsules are translucent. Sepals are shorter than the petals.

nice chickweed with five stigma. (stelllaria has three). nice comparison between these two. love it


Marvellous!!!


I think it will be Cerastium glomeratum as per images and details herein and as per discussions at Id request for this species of Arenaria


On further consideration, it appears close to Cerastium holosteoides as per POWO (syn: Cerastium fontanum subsp. vulgare (Hartman) Greuter & Burdet of Flora of China)


On further consideration, I think it will be Cerastium glomeratum as per discussions at  Confusion between Cerastium fontanum subsp. vulgare and Cerastium glomeratum


C. glomeratum if we follow POWO



/wp-content/uploads/2020/10/dscn4761a.jpg
stellaria again…: There was a post yesterday about stellaria.. (could not find it again today).. anyway I just wanted to confirm if these two are also stellarias (media/graminea or what??)..
Again from my area of Dalhousie,HP, Alt 2300mts

– Here’s a photo of the leaves..


– This is Cerastium fontanum (syn: C. vulgatum)

Pl. correct.


Yes, it is very much Cerastium glomeratum.
