Kindly identify the species of Cuscuta growing in Delhi. I suspect there are two species of Cuscuta here, the one with orange-brown thinner stem is flowering and the other with yellow-green thicker stem (C. reflexa?) is not flowering.
Thank you,
With best regards,
Chitralekha

Thank you Prof. Munshi and Surajit. I am confused; Is it Cuscuta chinensis or C.campestris? How can we differentiate between them?
Best regards,
Chitralekha

Yes, Madam, you are correct, it is more likely C. campestris Yuncker, provided it is distributed in your area. However, difference can be found in FoC or FoP KEY. Perhaps host plant described there may help reach further conclusion.

Thank you

Thank you Surajit. In Flora of Delhi ((1963) only two species of Cuscuta are reported to be growing in Delhi, C. reflexa and C. hyaline. I tried FoP but could not conclusively identify the species.

Madam,

I Haven't received your mail yesterday, instead replying in the group site directly. This is getting complicated. Please check my thread, I have uploaded a little while ago - https://groups.google.com/d/msg/indiantreepix/4juCgPJGMN8/YHpA9ZMONDEJ.

I think your species look similar to mine.

Your species doesn't look like C. hyalina, for flowers should have acuminate to caudate petals and acute to acuminate sepals. Please check-


Thank you
Regards
surajit

You are right Surajit. It does appear to be C. chinensis which probably has not been reported from Delhi.
Thanks.

Madam,

Now I am confused, I have identified my species (at https://groups.google.com/forum/#!topic/indiantreepix/4juCgPJGMN8) as Cuscuta campestris, based on Flora of China KEY -
(i) capsule entirely enclosed by withered corolla = chinensis
(ii) capsule subtended by withered corolla = campestris

Thank you
Regards

Yes, Surajit. I am now fully convinced that it is Cuscuta campestris. I dissected the flowers and found them to be exactly as described in Flora of China.
Thank you,
Regards,
Chitralekha

Thank you very much Madam. I also tried to dissect those flowers to see scales! But it was impossible to me to see anything inside.

With regards
surajit

Dear Surajit,
The scales are very much there. They are present where the filaments have fused with the petals (attached photo).Can I also call them coronal outgrowths? if yes, are they then petaloid or staminal in origin? The host in this case is Clerodendrum inerme. After flowering the parasite withers and dies. I am yet to see the other Cuscuta species (probably C.reflexa) with the greenish-yellow stem flower in Delhi. 
Like C. reflexa, C. campestris  too shows self-parasitism though not as aggressively.
Best regards,
Chitralekha

Thank you again so much Madam, I also noticed those translucent growth, but couldn't make out their shapes. Neither could I focus my camera to take a snap.
Yes, I also noticed Clerodendrum is their host, in our case is Clerodendrum infortunatum.

Thank you once again.

Thanks Ushadi. Surajit, there are five delicate translucent scales with inward-facing finger-like  projections at their tips (fimbriolate?) . Will try to get a better picture.

Yes, Madam, I can very well see the finger like projections in the photograph you have uploaded.

I thank you very much for this excellent learning session.
