''Trichosanthes cucumerina'' is a tropical or subtropical vine, its variety ''T. cucumerina'' var. ''anguina'' raised for its strikingly long fruit, in Asia eaten immature as a vegetable much like the summer squash, and in Africa, the reddish pulp of its mature fruit is used as an economical substitute of tomato.〔Kew Gardens. Snake gourd ''Trichosanthes cucumerina'' var. ''anguina''. http://www.kew.org/support-kew/adopt-a-seed/trichosanthes-cucumerina-var-anguina.htm〕 Common names of the cultivated variety include snake gourd,〔 serpent gourd,〔 chichinda,〔 and padwal〔(Flowers of India, snake gourd, ''Trichosanthes cucumerina'' )〕 (not to be confused with ''Trichosanthes dioica'', the parwal, another gourd edible when immature). ''Trichosanthes cucumerina'' is found in the wild across much of South and Southeast Asia, including India, Bangladesh, Nepal, Pakistan, Sri Lanka, Indonesia, Malaysia, Myanmar (Burma), and southern China (Guangxi and Yunnan).〔(Flora of China v 19 p 38, ''Trichosanthes cucumerina'' )〕 It is also regarded as native in northern Australia.〔(Florabase, the Western Australia Flora, ''Trichosanthes cucumerina'' )〕〔Coopper, Wendy E., & Hugo J.

''anguina'' (L.) Haines – cultivated variant * ''Trichosanthes cucumerina'' var. ''cucumerina'' – wild variant ==Description== ''Trichosanthes cucumerina'' is a monoecious annual vine climbing by means of tendrils. Leaves are palmately lobed, up to 25 cm long. Flowers are unisexual, white, opening at night, with long branching hairs on the margins of the petals. These hairs are curled up in the daytime when the flower is closed, but unfurl at night to form a delicate lacy display (see photos in gallery below). Fruits can be up to 200 cm long, deep red at maturity, hanging below the vine.〔〔〔 The related Japanese snake gourd (''Trichosanthes pilosa,'' sometimes called ''T. ovigera'' or ''T. cucumeroides''), very similar in vegetative morphology, but the fruit of ''T. pilosa'' is round to egg-shaped, only about 7 cm long.〔(Flora of China v 19 p 45, ''Trichosanthes cucumeroides'' )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trichosanthes cucumerina」の詳細全文を読む スポンサード リンク
