Citrullus colocynthis
Citrullus colocynthis, with many common names including colocynth, bitter apple, bitter cucumber, vine of Sodom, or wild gourd, is a poisonous desert viny plant native to the Mediterranean Basin and West Asia, especially the Levant, Turkey (especially in regions such as İzmir), and Nubia.
It resembles a common watermelon vine but bears small, hard fruits with a bitter pulp. The plant contains cytotoxic cucurbitacins and is thus unsafe to use as an herbal medicine. It originally bore the scientific name Colocynthis citrullus.
The vine ranges from 2.4–3 metres (8–10 feet) in length.
The roots are large, fleshy, and perennial, leading to a high survival rate due to the long tap root. The vine-like stems spread in all directions for a few meters looking for something over which to climb. If present, shrubs and herbs are preferred and climbed by means of auxiliary branching tendrils.
Very similar to watermelon, the leaves are palmate and angular with three to seven divided lobes.
The flowers are yellow and solitary in the axes of leaves and are borne by yellow-greenish peduncles. Each has a subcampanulated five-lobed corolla and a five-parted calyx. They are monoecious, so the male (stamens) and the female reproductive parts (pistils and ovary) are borne in different flowers on the same plant. The male flowers' calyx is shorter than the corolla. They have five stamens, four of which are coupled and one is single with monadelphous anther. The female flowers have three staminoids and a three-carpel ovary. The two sexes are distinguishable by observing the globular and hairy inferior ovary of the female flowers.
The fruit is smooth, spheric with a diameter of 5 to 10 centimetres (2 to 4 inches) and an extremely bitter taste. The calyx englobe the yellow-green fruit which becomes marble (yellow stripes) at maturity. The mesocarp is filled with a soft, dry, and spongy white pulp, in which the seeds are embedded. Each of the three carpels bears six seeds. Each plant produces 15 to 30 fruits.
The seeds are gray and 5 millimetres (1⁄4 in) long by 3 mm (1⁄8 in) wide. They are similarly bitter, nutty-flavored, and rich in fat and protein. They are eaten whole or used as an oilseed. The oil content of the seeds is 17–19% (w/w), consisting of 67–73% linoleic acid, 10–16% oleic acid, 5–8% stearic acid, and 9–12% palmitic acid. The oil yield is about 400 L/hectare. In addition, the seeds contain a high amount of arginine, tryptophan, and the sulfur-containing amino acids.[citation needed]
