                              Healthy Watermelon Fruit

Citrullus lanatus is a plant species in the family Cucurbitaceae, a vine like scrambler and trailer flowering plant originally from West Africa. It is cultivated for its fruit. The subdivision of this species into two cultivars, watermelons Citrullus lanatus Thunb. var. lanatus and citron melons.originated with the erroneous

synonymization of Citrullus lanatus Thunb. Matsum. & Nakai and Citrullus vulgaris Schrad. by L.H.Bailey in 1930.  

 Molecular data including sequences from the original collection of Thunberg and other relevant type material, show that the sweet dessert watermelon Citrullus vulgaris Schrad. and the bitter wooly melon Citrullus lanatus Thunb. Matsum. & Nakai are not closely related to each other.  Since 1930, thousands of papers have misapplied the name Citrullus lanatus Thunb. Matsum. & Nakai for the dessert watermelon, and a proposal has therefore been submitted to conserve the name with this meaning. The bitter wooly melon was formally described by Carl Peter Thunberg in 1794 and given the name Momordica lanata.  It was reassigned to the genus Citrullus in 1916 by Japanese botanists Ninzo Matsumura and Takenoshin Nakai. The sweet dessert melon was formally described by Carl Linnaeus in 1753 and given the name Cucurbita citrullus. It was reassigned to the genus Citrullus in 1836 by the German botanist Heinrich Adolf Schrader.

The bitter wooly melon is the sister species of Citrullus ecirrhosus Cogn. from South African arid regions, while the sweet dessert melon is the sister species of mucosospermus  Fursa from West Africa. DNA data reveal that C. lanatus var. citroides Bailey is the same as Thunberg's bitter wooly melon, C. lanatus and also the same as C. amarus Schrad. It is not a form of the sweet dessert melon C. vulgaris and not closely related to that species. The citron melon or makataan a variety with sweet yellow flesh that is cultivated around the world for fodder, and the production of citron peel and pectin. The dessert watermelon is an annual that has a prostrate or climbing habit. 

Stems are up to 3 m long and new growth has yellow or brown hairs. Leaves are 60 to 200 mm long and 40 to 150 mm wide. These usually have three lobes which are themselves lobed or doubly lobed. Plants have both male and female flowers on 40-mm-long hairy stalks. These are yellow, and greenish on the back.
