Hooghly Today : Cereus pterogonus Lemaire ?: I have a pocket field guide in Bengali that illustrates about 20 wild shrubs and a few climbers that can be found in bushes. This book, BANGLAR JHOPJHAR (Anirban Roy, pub. PASCHIMBANGA JIB-BAICHITRA PARSHAD) illustrates a plant, Cereus pterogonus Lemaire. The Bengali name mentioned in this book is TESHIRA (তেশিরা). This book also features a photograph of this plant.
Couldn’t find this genus in Bengal Plants or in any eflora.
But, “Hortus Suburbanus Calcuttensis” mentions the following Cereus species :-
This is a common plant in rural area and can attain a height of about 10 ft.
An image search for Cereus yields similar looking plants, and i think it might be accepted as Cereus sp, subject to experts’ views.

Kindly identify this cactus with huge white flowers photographed in July 2018 at a fence of a farm in Anuppur district, Madhya Pradesh.
Could it be Selenicereus testudo?
Yes, appears close.
lists Cereus pterogonus as an “unresolved name”. Please clarify.
Could it be Cereus repandus?
Thanks, … Tropicos gives Cereus pterogonus as a syn. of Selenicereus testudo (Karw. ex Zucc.) Buxb.
