Rhaphidophora (Araceae)?


I think the plant is Epipremnum pinnatum.


Whatever the plant may be, just to bring to your notice that, its actually wrong to say “INCORRECTLY NAMED AS”. The best word to describe such name is “SYNONYM” !!
Please mail me the pic ... I will try to send it to friend of mine and another Araceae expert, Dr. David Scherberich at France.


It could be a var. of Philodendron.


Could be Monstera obliqua. common name window leaf


Yes, It is Monstera obliqua.
comonly available in nurseries in Maharashtra.


Following are the replies from Dr David Scherberich ((http://www.aroidpictures.fr)) and Botanist Peter Boyce who did the revision of the genus Rhaphidophora

Dr David Scherberich’s reply is as follows ———————————————————–.
Thank you for your message. Do you have any information on the origin of this plant?
I think it is most probably a Monstera but I am not sure about the species.
Among other characteristics, the perforations of the leaves clearly excludes the genus Philodendron. Neither is it Epipremnum pinnatum. The stem on this species is always distinctly ridged. You can see it here:
Another thing, the leaves on Epipremnum pinnatum also have typical very small holes along the midrib. It is not very obvious on my pictures but you can guess them on the leave on the back here:
—————-
When I replied to him that the plant is from Maharashtra India the following was his reply …,
I am glad I could help you.
Monstera is a genus of about 60 species but it is exclusively from tropical America.
I think that your plant is probably Rhaphidophora pertusa (Roxb.) Schott, a species from Southern India, Bangladesh and Sri Lanka. I am not very familiar with that species, now if you would like to be sure you could ask Peter Boyce who did the revision of the genus Rhaphidophora. His email address is ….
I am joining here for you an article on three aroids from Bangladesh with a drawing of R. pertusa.

I wrote to Mr Peter Boyce who replied
I can confirm that this is definitely Rhaphidophora pertusa (Roxb.) Schott;
Here is the entry form the forthcoming Flora of Thailand account. Note in particular the full (confirmed) natural range.

Valparai TBN 280614 for id/ TBN June 7 : 13 posts by 7 authors. Attachments (1). Please identify this creeper seen in the rain forest at Valparai. 


This looks like a species of Monstera.


I am agree with …


What about Philodendron domesticum?

In Monstera the leaves are much dissected! Were the leaves dissected in the plants ? 


I understood that the creeper is the same or it resembles the common ornamental creeper used in landscaping which has split leaves. I an sorry, I am not sure about the name.


Epipremnum species (earlier Pothos )


If from wild, it may be Rhaphidophora pertusa.


I think … got it right


Thanks … However leaves seem to be entire and not divided.


Both the types of leaves (pinnatisect and entire) are present in this species.
