1- Introduction to the Subfamily Cucurbitoideae (Gourd Subfamily)
1.1- Overview The Cucurbitaceae, also cucurbits, are a plantfamily, sometimes called the gourd family, consisting of around a hundred genera. The plants in this family are grown around the tropics and in temperate areas, where those with edible fruits were among the earliest cultivated plants both in the Old and New Worlds. The Cucurbitaceae family ranks among the highest of plant families for number and percentage of species used as human food. Most of the plants in this family are annualvines, but some are woody lianas, thorny shrubs, or trees (Dendrosicyos). Many species have large, yellow or white flowers. The stems are hairy and pentangular. Tendrils are present at 90° to the leaf petioles at nodes. Leaves are exstipulate alternate simple palmately lobed or palmately compound. The flowers are unisexual, with male and female flowers on different plants (dioecious) or on the same plant (monoecious). The female flowers have inferior ovaries. The fruit is often a kind of modified berry called a pepo.
1.2- Subfamilies of the FamilyCucurbitaceae Depending on a classification system given by Charles Jeffrey in 1990 the family Cucurbitaceae had two subfamilies: 1.2.1- The Subfamily Cucurbitoideae + Overview TheCucurbitoideaeare a subfamily of the Cucurbitaceae, or gourd family, offlowering plants. The Cucurbitaceae are divided into two subfamilies, theZanonioideae (synomym = Nhandiroboideae), probably a paraphyleticgroup of remainders, and the well-supportedmonophyleticCucurbitoideae. Members of theCucurbiteaetribe produce economically valuablefruits, calledgourds, which includecropslikecucumbers,squashes (includingpumpkins),luffas, and melons (includingwatermelons).The Benincaseae tribe contains a genus calledLagenariawhose members produce gourds that can be eaten or whose shells can be dried and used as containers. + Tribes of the Subfamily Cucurbitoideae The Cucurbitoideae subfamily consists of 7 tribes: 1- Tribe Melothrieae (consisting of 4 subtribes) - Subtribe Dendrosicyinae: consisting of 16 genera - Subtribe Guraniinae: consisting of 3 genera - Subtribe Cucumerinae: consisting of 6 genera - Subtribe Trochomeriinae: consisting of 4 genera 2- Tribe Schizopeponeae (consisting of 1 genus) 3- Tribe Joliffieae (consisting of 2 subtribes) - Subtribe Thladianthinae: consisting of 4 genera - Subtribe Telfairiinae: consisting of 1 genus 4- Tribe Trichosantheae(consisting of 4 subtribes) - Subtribe Hodgsoniinae: consisting of 1 genus - Subtribe Ampelosicyinae: consisting of 2 genera - Subtribe Trichosanthinae: consisting of 3 genera - Subtribe Herpetosperminae: consisting of 4 genera 5- Tribe Benincaseae(consisting of 2 subtribes) - Subtribe Benincasinae: consisting of 17 genera - Subtribe Luffinae: consisting of 1 genus 6- Tribe Cucurbiteae (pantoporate, spiny pollen): consisting of 13 genera 7- Tribe Sicyeae (consisting of 2 subtribes)(trichomatous nectary, 4- to 10-colporate pollen grains) - Subtribe Cyclantherinae: consisting of 13 genera - Subtribe Sicyinae: consisting of 7 genera
