[taffa...@gmail.com]

Dear members,

Please help ID this herb  (Cardamine sp ? ).

Habitat :  A lawn in Srinagar

Habit : Annual Herb erect about 30cm high . Sometimes branched at base. Leaves with 4 to 5 mostly paired leaflets, Leaflets with 2-3 unequal lobes with one lobe much smaller than others Flowers white 4-5mm in diameter. Stamens 6 tetradynamous (4 long(filament 2mm) and 2 short(filament 1.5mm)). Anthers yellowish green with filaments attached basally and notably tips of anthers curled anticlockwise (See Photo 6). Pollen grains are fusiform as in some other crucifers. Stigma covered with elongated papillary cells as in other members of the family(see Photo7).All photos taken recently in the first week of May.

Regards

Taffazull

Notes:

1.Anthers are remarkable in having the tips curled back in an anticlockwise fashion (see photo9 and Photo 6).

2.Papillary cells on Stigma (Photo 7 ) are said to play an important role in preventing self pollination and promoting cross pollination in this family.

Dear Saroj ji,

Thanks for the link.

It cant be C.hirsuta as there are 6 stamens. Also in Srinagar it was flowering in Feb -March when I reported it.

It is peculiar in having yellowish green anthers with tips curled back in an anticlockwise manner like the horns of a sheep. Unfortunately none of the photos in your link have photos of anthers. The anthers of C.flexuosa are clearly visible in a Wikipedia photo (By Didier Descouens - Own work, CC BY-SA 4.0, https://commons.wikimedia.org/w/index.php?curid=115306437) and they are yellow and do not have curled tips. So from  anthers it is very different from C.flexuosa.

Some expert can enlighten us further.

Dear Garg ji,

Thanks for the appreciation

I think if one has a magnifying glass the green anthers with tips curled anticlockwise can provide additional confirmation.

It should be " green anthers with tips curled downwards(towards abaxial side).." and not "..curled counterclockwise.."
