Cardamine impatiens L., Sp. Pl. 655 1753. (Syn: Cardamine apetala Gilib. [Invalid]; Cardamine apetala Moench; Cardamine basisagittata W.T.Wang; Cardamine brachycarpa Opiz; Cardamine dasycarpa M.Bieb.; Cardamine glaphyropoda O.E.Schulz; Cardamine glaphyropoda var. crenata T.Y.Cheo & R.C.Fang; Cardamine impatiens var. acutifolia Knaf ...............; Cardamine nakaiana H.Lév.; Cardamine saxatilis Salisb.; Cardamine senanensis Franch. & Sav.; Crucifera impatiens E.H.L.Krause; Ghinia impatiens Bubani ..); 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... Kalatope id al200311: Location Kalatope Chamba dist. Altitude 2100 mt Habit herb Habitat: wild Height: 12 inches - Yes Cardamine impatiens (bittercress) Cardamine impatiens from Khillenmarg, Kashmir: Cardamine 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. Photographed from Khillenmarg Kashmir in July, 2011 In this and several other crucifers basal leaves form a rosette before the areal portion elongates.

(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. Cardamine impatiens for validation:: NS June 19 : 2 posts by 2 authors. Attachments (3). 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 Cardamine species/ABFEB12 : 5 posts by 3 authors. Attachments (3) This plant is growing abundantly here on the ground and through the stone crevices. Is it a Cardamine sp? Cardamine imaptiens perhaps?
