Jan2015sk22 Hooghly - Cuscuta sp. ID please

[surajit koley]

This is the most common species found along rail-tracks, roadside. It grows on herbaceous weeds. Today I have recorded from three places, chief vegetation found is of Mikania, Alternanthera, and other weeds. Earlier one such species was identified as C. chinensis. One post by Giby Sir, identified as C. campestris looks similar to this species.

I think this species also looks similar to FoZ or the one in http://keys.lucidcentral.org/keys/v3/eafrinet/weeds/key/weeds/Media/Html/Cuscuta_campestris_(Golden_Dodder).htm.

Sir Prain listed only one species - reflexa, Haines recorded two in Bihar - reflexa and chinensis. But a report informs campestris is present in our state - http://www.indianjournals.com/ijor.aspx?target=ijor:ijws&volume=41&issue=1and2&article=001.

Please help.

Thank you
