Tinda is a plant from the family of cucurbits (Cucurbitaceae), whose fruits in Asia and vegetables are used. It is the only species in the Praecitrullus genus.
features
The species is an annual climbing plant. The shoot axes are relatively strong, the hair is shaggy. The tendrils are slender and two to three parts.
The leaf stalks are hairy. The leaves are slightly pinnate. The leaf blade is scattered wire-haired, densely wire-haired on the main nerves and the small nerves on the underside. The leaf margin is finely serrated. The cover sheet is spatulate and around 0.8 cm long.
The plants are monoecious . The single flowers are small and yellow. In the male flowers, the peduncle is around one millimeter long, the calyx is bell-shaped, hairy and has inverted conical tips that are around eight millimeters long. One of the three stamens is free, the others are fused. The pollen grains are prickly. The female flowers have a broad, bell-shaped calyx with lanceolate tips about five millimeters long. The ovary is pubescent. The fruits are approximately spherical and around six centimeters in diameter. The seeds are oblong-oval and around eight millimeters long. Their surface is smooth and yellowish-white. The seed coat has three layers.
The number of chromosomes is 2n = 24.
Systematics
The species was previously placed in the genus Citrullus , but differs significantly from it in the number of chromosomes and other features, and cannot be crossed with it. It is now listed as a separate genus within the tribe Benincaseae and is the sister taxon of the wax gourd ( Benincasa ).
Dissemination and use
The species is native to India and Pakistan and is grown in the north of both countries, where the ripe fruits are a popular vegetable. The harvest takes place before the seed coats harden. After removing the seeds, the fruits are cooked, often together with lentils . They are also inserted. The seeds are eaten roasted. There are two forms: one with light green fruits, which is generally preferred, and the other with dark green fruits.
