In N India and the Himalayas there is only one species that has a pseudostem with 2 or more pedatisect leaves showing a substalk (rachis) on which the leaflets are arranged AND an inflorescence with a upward facing, elephant trunk like appendix and that is tortuosum. Any species having this combination of characters from N India is Arisaema tortuosum so yes, the plant on the pictures is tortuosum. The leaflets can be broad and often with ruffled edges (sometimes referred to as “helleborifolium) or narrow and almost lanceolate (referred to as “curvatum” and predominantly present in W Himalaya). The pseudostems can range from all green to heavily striated showing the variation characteristic of widespread species.
In S India the tortuose appendix occurs in more species with 2 having a single leaf (neglectum and sivadasanii) and 1 with 2 or more leaves (tortuosum). Both single leaved species are mostly confined to Maharashtra state but tortuosum occurs in more states. Sivadasanii is late flowering but still has a green inflorescence combined with a very short rachis whereas neglectum ranges from green to brown-beige flowered. Hope this helps.
