Spilanthes acmella confusion: 1-Blainvillea acmella from near Dakpathar:<\/a>\u00a0<\/span>\u00a0<\/span><\/p>\n<\/div>\n

Blainvillea acmella<\/i> (Linnaeus) Philipson, <\/span>Blumea 6 350 1950<\/cite>.<\/span><\/div>\n
syn: <\/span>Verbesina<\/i> acmella<\/i> L.; Blainvillea alba<\/i> Edgew.; Blainvillea platyphylla<\/i> DC<\/span>
\n<\/span><\/div>\n
Roughly hairy stiff erect herb; lower leaves opposite, upper alternate, ovate to deltate, up to 7 cm long, toothed; heads radiate, 8-12 mm in diam; phyllaries few, outer leaflike; ray usually white, 2-3 lobed, disc 5-merous; achenes 3-angled, inner flattened; pappus of 2-5 unequal bristles. <\/span><\/span>
\n<\/span><\/div>\n
Photographed from near Dakpathar on way to Chakrata.<\/span><\/span>\u00a0<\/span><\/div>\n
Perhaps no other binomial has been so cused as Spilanthes acmella<\/i><\/span><\/div>\n
The name Spilanthes acmella<\/i> is based on Verbesina acmella<\/i> L. The combination under Spilanthes<\/i> appeared in Syst. Veg., ed. 13″ 610 1774<\/cite>. Till recently the combination was attributed to Murray in many reputed books, Floras and<\/span> databases (The Plant List, eFlora publications,etc.) but as turns out Murray was only the editor of this publication and Linnaeus the author of this combination, which should correctly be cited as Spilanthes acmella<\/i> (L.) L. Flora of British India recognises four varieties under this: var acmella<\/i> proper, var. calva<\/i>, var. oleracea<\/i> and var. paniculata<\/i>. Interestingly Koster and Philipson (1950) discovered that the Verbesina acmella<\/i> L., actually belongs to Blainvillea<\/i> and should be better known as Blainvillea acmella<\/i> (L.) Philipson. The other names stay under newly recognised genus Acmella<\/i> and none (Indian species) under Spilanthes<\/i>. Incidently also the Blainvillea acmella<\/i> (L.) Philipson includes another species described in Indian Floras as Blainvillea platyphylla<\/i> DC.<\/span>\u00a0<\/span><\/div>\n
The species originally described as Spilanthes may accordingly include following within Indian boundaries:<\/u><\/span>
\n<\/span><\/div>\n

Very nice description with detailed keys.
\n<\/span>yes, to me also <\/span>Blainvillea acmella<\/i> (L.) Philip.
\n<\/span>Syn: <\/span>Verbesina acmella<\/i> L.; <\/span>Blainvillea latifolia<\/i> (L. f.) DC.; <\/span>Eclipta latifolia<\/i> L. f.; <\/span>Blainvillea rhomboidea<\/i> Cass.
\n<\/span>Anyway it is not coming under the genus <\/span>Spilanthes<\/i> (Syn: <\/span>Acmella<\/i>).
\n<\/span><\/p>\n

\n

Although not given in the original key of Acmella<\/i> Monograph by Jansen, but in the description is mentioned that heads of Acmella calva<\/i> are mostly discoid but may be rarely radiate. I have as such modified the key for Indian species to accomodate this. This is also available on our website:\u00a0\/species\/a—l\/ar\/asteraceae\/acmella<\/span><\/a><\/p>\n

syn: <\/span>Verbesina<\/i> acmella<\/i> L.; Blainvillea alba<\/i> Edgew.; Blainvillea platyphylla<\/i> DC<\/span>
\n<\/span><\/div>\n
Roughly hairy stiff erect herb; lower leaves opposite, upper alternate, ovate to deltate, up to 7 cm long, toothed; heads radiate, 8-12 mm in diam; phyllaries few, outer leaflike; ray usually white, 2-3 lobed, disc 5-merous; achenes 3-angled, inner flattened; pappus of 2-5 unequal bristles. <\/span><\/span>

Photographed from near Dakpathar on way to Chakrata.<\/span><\/span><\/div>\n
Perhaps no other binomial has been so confused as Spilanthes acmella<\/i><\/u><\/div>\n
The name Spilanthes acmella<\/i> is based on Verbesina acmella<\/i> L. The combination under Spilanthes<\/i> appeared in Syst. Veg., ed. 13″ 610 1774<\/cite>. Till recently the combination was attributed to Murray in many reputed books, Floras and databases (The Plant List, eFlora publications,etc.) but as turns out Murray was only the editor of this publication and Linnaeus the author of this combination, which should correctly be cited as Spilanthes acmella (L.) L. Flora of British India recognises four varieties under this: var acmella<\/i> proper, var. calva<\/i>, var. oleracea<\/i> and var. paniculata<\/i>. Interestingly Koster and Philipson (1950) discovered that the Verbesina acmella<\/i> L., actually belongs to Blainvillea<\/i> and should be better known as Blainvillea acmella<\/i> (L.) Philipson. The other names stay under newly recognised genus Acmella<\/i> and none (Indian species) under Spilanthes<\/i>. Incidently also the Blainvillea acmella<\/i> (L.) Philipson includes another species described in Indian Floras as Blainvillea platyphylla<\/i> DC. The species originally described as Spilanthes<\/i> may accordingly include following within Indian boundaries:<\/span>
