Cardamine impatiens revisited ABFEB2018/01 : 5 posts by 3 authors. Attachments (16)

I have been photographing and observing this bitter cress since late December. Even though the hairy auricles on the carline leaves point straight to C. impatiens, some characteristics such as the persistent basal rosettes of leaves leave some doubt and I seek the opinion of experts on this.
Cardamine impatiens?
Mcleodganj and above, Dharamshala, HP
1750-1850m
Photos from 13 January onwards.
First some observations I have made:
Habit: 10-40cm tall
Flowers: White, 4-petals, corolla 4-6mm across, pedicels 1-1.5cm, 6 stamens always
Calyx: Sepals 4, slightly pink to brown, shorter than petals (about half in length)
Fruit: greenish-brown to claret, ca 2.5cm long, pedicel 1.5cm, upright
Leaves: Compound, basal ones with round lobes, 6-18cm long, leaflets 1.5 x 2cm (width x length), carline leaves with narrower leaflets 0.8 x 2.5cm. Leaf-stems grooved, with scattered hairs and join the main stem in hairy auricles. Basal leaves in rosettes which are present at the time of flowering.
Now from the FOC, which also has an excellent illustration;
Herbs biennial or rarely annual, (12-)20-65(-90) cm tall, glabrous or rarely sparsely pubescent near base. Stems erect, simple at base, usually branched above, angled, sometimes flexuous. Basal leaves rosulate, often withered by flowering; petiole 1-4 cm, not auriculate; leaf blade pinnatisect and appearing compound. Cauline leaves to 15 per stem; petiole auriculate, 2-6 cm; auricles lanceolate or linear, 1-8(-10) × (0.1-)0.3-1.8(-2.2) mm, often ciliate; leaf blade (1-)3-18(-22) × (0.6-)1-5.5(-7) cm, pinnatisect; terminal lobe orbicular, obovate, ovate, or lanceolate, 1-4(-5) × 0.5-1.7 cm, with a petiolule to 5 mm, entire or obscurely to strongly 3-5(-9)-toothed or -lobed; lateral lobes (4-)6-11 on each side of midvein, oblong, lanceolate, or ovate, sessile or long petiolulate, smaller than terminal lobe, margin dentate, sublaciniate, or rarely entire; uppermost leaves with narrower segments. Fruiting pedicels divaricate or ascending, 3.5-12(-15) mm, slender. Sepals oblong, 1.2-2(-2.5) × 0.7-1(-1.2) mm. Petals white, oblanceolate, 1.5-4(-5) × 0.6-1.2 mm, rarely absent. Stamens 6; filaments 2-3(-4) mm; anthers ovate, 0.3-0.5 mm. Ovules 10-30 per ovary. Fruit linear, (1-)1.6-3(-3.5) cm × 0.9-1.5 mm; valves glabrous or rarely pilose, torulose; style 0.6-1.6(-2) mm. Seeds brown, oblong, 1.1-1.5 × 0.8-1 mm, compressed, sometimes apically narrowly winged. Fl. and fr. Feb-Jul. 2n = 16, 32.
I could not tell if the basal leaves had auriculate petioles without damaging the plant but noticed that the rosettes stay and do not wither away even after observing almost fifty plants. I cannot confirm the ‘often withered by flowering’ part of the above description.
Our plants could be C. hirsuta but the petioles are not supposed to be auriculate in that species and the stamens are more often 4. So we can rule that out as our plants have consistently 6 stamens and auriculate petioles.
The same with C. flexuosa which is supposed to have no basal rosette of leaves and no auriculate petioles. So no C. flexuosa either.
FOC admits that the species can be very variable but the auriculate petioles are unique to C. impatiens among these three.
There is always a possibility that our plants do not belong to any of the three species mentioned above but I do not know the other possibilities as my knowledge is severely  limited.

No words to describe your such detailed endeavors with plants for the benefit of everybody. Thanks, …


Very beautiful and detailed post …, I agree that this is Cardamine impatiens

Cardamine impatiens from Khillenmarg, KashmirCardamine impatiens L., Sp. pl. 2:655. 1753 Common name: Narrow-leaf bittercress Cardamine impatiens is easily identified from other species of the genus by auricled leaf bases and leaves with narrow leaflets. Herb up to 50 cm tall, usually erect, glabrous or sparsely hairy; leaves pinnate with 11-23
ovate-lanceolate dentate to laciniate leaflets; flowers white, 3-4 mm across, in 20-30-flowered racemes elongating to 15 cm in fruit; fruit linear, compressed, 2-3 cm long, glabrous.
Growing commonly at higher altitudes in forests, among rocks and low shrubs.

In this and several other crucifers basal leaves form a rosette before the areal portion elongates.

Morni Hills 2014: Cardamine for id:: NS March 02 : 5 posts by 2 authors. Attachments (6).
This small herb is in flowering these days.. (1.3.14)

I hope this is a Cardamine sp… please help to get specific id..


I think Cardamine impatiens. Check for auricled stipules.


Thank You Sir.. perhaps this is the right choice….

I tried to fit this to any one of C. scutata, C. hirsuta or C. flexuosa but none of them seemed appropriate..

I could not get proper picture, but a cropped picture is attached here to show the leaf base, if this can be of any help…


I think yes C. impatiens.

This soft herb was shot from Chakrata, earlier also from Morni Hills in Haryana..
Hopefully this is Cardamine impatiens..

Please validate/suggest the proper id..


I think yes

This plant is growing abundantly here on the ground and through the stone crevices. Is it a Cardamine sp? Cardamine imaptiens perhaps?

Looks like Cardamine impatiens

Identifiation for this Cardamine sp.: 3 + 5 high res. images.
Location:Kulgam.

Habit: small herb.


Cardamine impatiens L. ??


What minimum we want for a proper id is a habit image, habitat image, side view of the flowers showing calyx, clear picture of the leaves showing its position on the stem or branch etc.
Images posted by you are mostly flowers (without showing calyx and sepals).
Our given ids here are going to be wrong (despite our best efforts), even if provided based on your incomplete set of images. Also it takes about three to four times more effort to arrive at tentative ids based on such incomplete sets.
We are ready to help you with the ids, provided to post a complete set of images.
So pl. post a complete set of images (you can post as many as you want within 8 mb at a time and remaining in reply to the same mail) in the 1st instance only.
Based on these images, Cardamine macrophylla Willd. is also possible.


Please check again sir. I have added more photographs.
5 images.


Such images are required in the initial mail itself.


I don’t think it matches with Cardamine macrophylla !


C. macrophylla would have much larger flowers and distinctly toothed leaves, this should be C. impatiens only, first image does suggest auricles at base, leaves somewhat lobed but margin entire. Image focusing the leaf base would clinch the issue.
