Small herb for ID :: Palakkad :: MK011 SEP2016 : 9 posts by 4 authors. Attachments (2)

Please help to identify this small trailing herb on ground. Is this closely associated with Sesame?

Habitat: near agricultural field

Place: Palakkad Dist., Kerala

Date: July 25, 2016

Alt.: 150 m asl

Seasamum sp, Pedaliaceae

Thanks …, could this be Sesamum prostratum?

Looks different from images of this species at

For ID 040713GK

Identification please ID No-012

Adding the fruits of the same plant photographed in 16 October 2016 at the same location.

It does match with Sesamum prostratum as per this picture and herbarium.

ID request 24072011MC1: Request plant identification. Photographed on 24 July, 2011 in Besant Nagar,
Chennai, Tamil Nadu.

Small prostrate creeper. Flowers are about 2.5 cm long; growing wild.

Found in the same habitat Pedalium murex was growing.

Nice photograph of Sesamum laciniatum (Family: Pedaliaceae). Thanks for sharing.

This is Sesamum prostratum as per GBIF The Linnean Collections FRLHT POWO

I am also attaching a source for comparison..! !

Request identification of flower. Found at sea level near beachside south of chennai. Jan, 2010. about 3cm long, 2 cm wide.

Looks like Sesamum laciniatum for me.

Yes, it is Sesamum laciniatum. Note the lip touching the ground to allow pollinators like ants to climb on to a ramp to reach the nectary

Sesamum prostratum Retz. –Pedaliaceae

Sesamum sp.

It should be Sesamum laciniatum as per Flora of Karnataka GBIF

Look right to me…! !

I too agree with you

Now, Sesamum prostratum Retz., Observ. bot. 4:28. 1786-1787 (“1786”) (syn: Sesamum laciniatum Klein ex Willd.; Sesamum prostratum var. laciniatum (Klein ex Willd.)

Please check with Sesamum prostratum Retz

Sesamum prostratum is correct I feel.

Is this the same, Sesamum laciniatum Klein ex Willd. ?

It should be Sesamum laciniatum as per Flora of Karnataka GBIF

I too agree with you

I found this on grassland of GIB sanctuary, Nannaj -Dist. Solapur in Maharashtra.

RE.: size of photo : I would suggest for beginners to try this free download @ their own discretion please.

hope this helps,

This is Sesamum laciniatum, a prostrate plant of the dry regions. Please note the lip of the corolla which is touching the ground. This helps the tiny ground insects (pollinators)to climb into the flower. You might have noted the cut (laciniated) margins of leaves.

This is interesting.. When I had gone to Nanaj, I observed a sunbird feeding on a similar looking flower on the ground. I had photographed
it as well, but unable to locate it now.

Thanks for correcting, nclosed the another pix FYI plz,

Sesamum laciniatum in FOI : 5 posts by 2 authors.

Images of Sesamum laciniatum in FOI by Rajaram ji should be of Sesamum prostratum as per GBIF The Linnean Collections FRLHT POWO
Pl. correct.

Thank you …,

Sesamum laciniatum is a synonym of Sesamum prostratum. Corrected now.

No. It is not a syn. Both are separate taxas.

Pl. see details at Sesamum prostratum and Sesamum prostratum var. laciniatum (syn. Sesamum laciniatum)

Plants of the World Online treats it as a synonym. They use a 2015 paper as reference:

Bedigian, D. (2015). Systematics and evolution in Sesamum (Pedaliaceae), part 1: evidence regarding the origin of sesame and its closest relatives Webbia; Raccolta de Scritti Botanici 70: 1-42.

I hope there are later publications treating Sesamum laciniatum and Sesamum prostratum as separate.

Thanks, …. Yes, very important paper.

Morphologically leaves of both look quite different. But in view of the paper you stated I have to merge both as per abstract:

Recent molecular studies demonstrate that Sesamum sect. Sesamum, deﬁning the largest genus of Pedaliaceae, holds two subspecies: the oilseed crop Sesamum indicum, and the crop’s progenitor Sesamum indicum subsp. malabaricum, and fail to support the idea that cultivated sesame originated from the African Sesamum latifolium. Therefore, in this updated classiﬁcation, Sesamum sect. Sesamum is re-circumscribed to contain the Asian progenitor species of sesame. As a result, these data do not support the current infrageneric classiﬁcation system; instead, these molecular results offer alternative implications with regard to the evolution of the genus and provide a basis for developing an updated taxonomy that is consistent with underlying phylogenetic relationships. Each clade is recognized as a section, thereby retaining valuable information on evolutionary relationships while minimizing nomenclatural changes. These analyses also reveal that section Sesamum is sister to Sesamum sect. Chamaesesamum. That section holds two species, Sesamum laciniatum and Sesamum prostratum, that have frequently been treated as distinct, but are combined here.
