Herb ID request – RK23 – 17-Oct-2012:<\/a> 5 images.<\/div>\n
Another small herb of around 1.5 feet height<\/font> in Mumbai<\/font>. It has small but one of the most beautiful yellow flowers. Would love to know its id.<\/p>\n
\n

Nice pictures of Ludwigia<\/em> sp., most probably L. perennis<\/em>.<\/p>\n

\n

Excellent images & very interesting post too …
Most likely to be L. prostrata<\/em>.
This is the most uncommon of the Ludwigia<\/em> species around Mumbai<\/font>, please share it’s location.
A word of caution: Ludwigia’s need closer scrutiny for definitive identification down to species level.<\/p>\n

\n

This plant confirms the identity of your earlier post of Ipomoea aquatica<\/i> from similar habitat. Coming to this plant Id: it is Ludwigia <\/i>species. I remember we had a long discussion with … throwing up light on the key about the Ludwigia <\/i>species.
Stamens need to be checked carefully.<\/p>\n

\n

Thanks a lot … for your responses. The pictures were taken at Kala Nagar in Bandra<\/font>. In case I happen to see it again, could you please suggest what to check and photograph to be able to identify the species. <\/div>\n

\n
I am highly confused with this plant.<\/div>\n
I request Iswar Barua ji to help with the id of this plant.<\/div>\n
Is it\u00a0Ludwigia perennis<\/em> L.? If so, are the images at\u00a0Ludwigia perennis<\/em><\/font><\/a>\u00a0correctly identified ?<\/div>\n
I also request him to pl. comment on other ids, I have marked to him.\u00a0<\/p>\n
\n<\/div>\n
\n
Or is it Ludwigia prostrata<\/em> Roxb. as fruit appears to be\u00a04 angular, although leaves appears to be different from those give in The Genus Ludwigia (Onagraceae) in India<\/font><\/a> by I.C. Barua- Rheedea Vol. 20 (1) 59-70 2010 (pdf available in this efi\u00a0thread).<\/p>\n
\n

<\/font><\/p>\n

Can you check for\u00a0Ludwigia\u00a0octovalvis<\/em>?<\/font><\/div>\n
Posted by me earlier and identified as above by …<\/font><\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Thanks, …,\u00a0I have checked. It is not this species.\u00a0<\/div>\n
