Looks different from Arisaema costatum
Pl. check Arisaema propinquum


The impressed leaf veins, the density of the veins and the lack of reticulation in the spathe all show this to be costatum. The altitude also indicates costatum, I assume this was photographed on Flower Hill? 


I feel it is more close to Arisaema costatum (Wall.) Mart. comparing 2 images.

For me there is no doubt it is costatum, it is easily recognisable. Even if it does not flower you can look at the leaves and you will see that the underside of the leaves of costatum has raised veins, see picture. I have seen costatum both north (Melamchigaon) and south of Kathmandu.
