Stachytarpheta cayennensis

Lamiaceae & Verbenaceae Week: Verbenaceae – Stachytarpheta cayennensis:
Stachytarpheta cayennensis (Rich.) Vahl

Very good clicks. Yet to see it.

nice
how do you differentiate it from the jamaica vervain?

I would not be able to make out among the Cayenne and Jamaican.
Clicking on last pic will lead to flickr photo page, where a flickr member, familiar with both the species, threw light on the differences.

I think we should take it as Stachytarpheta cayennensis (Rich.) Vahl in view of the links provided by … as below along with Factsheet links, for the time being: IFAS, Lucid Central: one, two, three and four

Is this the same as … posted earlier? Please refer: efi thread

your plant is stachytarpheta indica Vahl

could this be Jamaican species… I have seen it in a herbal garden in
southern suburbs of calcutta a few years ago…
I guess it could be Stachytarpheta jamaicensis of Verbenaceae
family.???  I was told than, all those years ago that it was a kind of
catmint??? or related to catmint… dont even have my hurriedly jotted
down notes now… but my brain seems to have stored this piece …
I wonder what would … say?

Stachytarpheta indica (L.) Vahl

Thanks …  However, both the species images look like same in the NET.  I am interested to know the key difference between the two species.

Pl. check comparative images in efi site.

Stachytarpheta indica

This is Stachytarpheta cayennensis (Rich.) Vahl as per details herein and as per comparative images at Stachytarpheta
Looks different from S.indica as per images and distribution at POWO

Thanks …, but i can’t make out the key difference.

Stachytarpheta jamaicensis from Hawaii-GS31012023-3: 3 very high res. images.
Stachytarpheta jamaicensis clicked by my son from Hawaii

To me it appears more closer to images at Stachytarpheta cayennensis (Rich.) Vahl

This should settle the issue:
