Acmella uliginosa (Sw.) Cass., “Dict. Sci. Nat., ed. 2 24” 331 1822. (Syn: Calea savannarum Standl. & Steyerm.; Ceratocephalus acmelia var. depauperata Kuntze …; Jaegeriau liginosa (Sw.) Spreng.; Spilanthes acmella var. uliginosa (Sw.) Baker; Spilanthes charitopis A.H.Moore; Spilanthes iabadicensis A.H.Moore; Spilanthes lundii DeCandolle; Spilanthess alzmannii DC.; Spilanthes uliginosa Sw.; Spilanthes uliginosa var. discoidea Aristeg.);
.
Marsh Para Cress ;
.
Annual decumbent herb with narrowly ovate to elliptic leaves, cuneate towards base, dentate margin; heads radiate; cone-shaped, especially when mature, 5-8 mm high, 4-6 mm in diam.; receptacle 4-6 mm high; ray florets 4-7, yellow-orange; disc florets more than 70, 4-merous, yellow-orange; achenes 1.2-1.8 mm long, black, margin ciliate with straight hairs; pappus bristles 2.
.
A. ciliata mainly differs from A. uliginosa is broader head and rounded to cordate leaf base.
.
Spilanthes calva is now known as Acmella calva, it is mostly with discoid heads but if with radiate heads, it can be easily separated from A. uliginosa by its pentamerous disc florets as against tetramerous in A. uliginosa.
.
A. paniculata has discoid head not rayed heads. In India, we have two species with rayed heads, viz. Acmella ciliata, & A. uliginosa and four species with discoid heads, viz. A. paniculata, A. calva, A radicans and A. oleracea. Another new species of Acmella with discoid heads from KERALA, INDIA is Acmella ghoshinis Sheela sp.nov. (Syn. Spilanthes ghoshinis Sheela sp.nov).

This seems to me Acmella uliginosa (Swartz) Cassini, but it looks like the one at FoI.

ID help :
Acmella from Hyderabad ID011212CS: Acmella uliginosa Have known this plant for many years as Spilanthus calva. Dr. Almeida’s book calls it Spilanthes clava [the clava part may be a typo]. It is a weed, a native of Moluccas [Maluku Islands]. There is no mention of Acmella uliginosa in any of the following :
– Cooke’s ‘Flora of Bombay Presidency’.
– Dr.Almeida’s ‘Fora of Maharashtra’.
– Yadav & Sardesai’s ‘Flora of Kolhapur District’.
– Bhagat, Shimpale & Deshmukh’s ‘Flora of Baramati’.
Have this plant on my property at Shahapur. Sending a few photographs. Kindly refer to my mail in the forum where I have tried to solve this confusion
There is presently no Indian species under genus Spilanthes, all have been transferred to Acmella.
Spilanthes calva is now known as Acmella calva, it is mostly with discoid heads but if with radiate heads, it can be easily separated from A. uliginosa by its pentamerous disc florets as against tetramerous in A. uliginosa.
In … above photographs besides ray florets, disc florests are clearly tetramerous and hence A. uliginosa. In your last photograph also disc florets appear to be tetramerous but you may confirm from a better. Thank you Sir for the clarification as I am using this flowering weed in my ecological engineering studies and have identified it as Acmella uliginosa I was getting a little worried. Should have posted earlier, but its been mad time at office and I am unable to keep up with my interests Thank you … for your detailed explanation. Was not aware of this new classification. Much obliged Acmella for ID : Pali,Maharashtra : 251212 : AK-1: It is Acmella paniculata, I hope it is Acmella uliginosa (Sw.) Cass. notA. paniculata.Because A. paniculata has discoid head not rayed heads. In India, we have two species with rayed heads , viz. Acmella ciliata, & A. uliginosa and four species with discoid heads, viz. A. paniculata, A. calva, A radicans and A. oleracea. Another new species of Acmella with discoid heads from KERALA, INDIA is Acmella ghoshinis Sheela sp.nov. (Syn. Spilanthes ghoshinis Sheela sp.nov). I hope it is Acmella uliginosa (Sw.) Cass. Looks to me like Acmella uliginosa.. Wild Herb ID please :: 19-Feb-2012 :: SK :: Hooghly, WB: It is a wild herb found inside an uncultivated area. There were many of them but all were confined to a small place only.
I thought it is Acmella ciliata, but the images available in the net feature difference in leaf blade.

sharing pixs of Acmella uliginosa from Pune. It was very interesting to see how this flower developed from almost flat to a conical form in a span of 11-12 days.
. Spilanthes calva DC (?) from Kamrup district (Rural), Assam: Most species of Spilanthes have been transferred to Acmella, A. calva typically has discoid heads but radiate heads are also known. A. uliginosa looks very similar in leaves and heads but has tetramerous flowers. Pl. check this if you have close up of head. Acmella calva (DC.) R.K.Jansen looks close Acmella calva (DC.) R.K.Jansen and Acmella paniculata are very close and confusing. Keys as per Acmella :
3a. Corolla white, greenish white or with purple tinge, 4-merous, pappus of 2-3 bristles …..Acmella radicans var. radicans
3b. Corolla pale yellow, yellow or orange yellow …(4)
4a. Pappus absent; stems decumbent, rooting at nodes; leaves ovate, ahenes 1.7-2.2 mm, glabrous, if sparsely hairy then hairs hooked ….Acmella calva
4b. Pappus of 2-3 bristles, achenes hairy, hairs straight, stems erect without nodal roots…..(5)
5a. Mature achenes with cork-like margin; surface tuberculate …….Acmella paniculata
