Citrus megaloxycarpa Lush.

Asm.: Bor-tenga, Jamir-tenga; Hindi: Attara; Tam.: Gajanimma. Amilbed or sour pomelo.

This apparently resembles the true pomelo (C. maxima) but is distinct in the presence of marginate or slightly winged petioles, purplish tinged petals, fruits containing bitterly sour juice and seeds with purple-coloured chalazal spot. The flowers look like that of a true lemon. The sour pomelo is suspected to be a hybrid between true pomelo and lemon.
