The name is not pumkin but pumpkin It is a plant from Cucurrbitaceae family ( it is from dicots)
Cucurbitaceae Juss.
Including Bryoniaceae Adanson ex Post & Kuntze,
Habit and leaf form.
Mostly more or less scandent, juicy herbs, or shrubs (rarely).
Plants non-succulent. Annual, or perennial; with neither basal nor terminal aggregations of leaves; perennials in temperate regions tuberous. Climbing (mostly, or more or less trailing), or self supporting; tendril climbers (often, the tendrils representing modified shoots, usually one per node), or scrambling (the tendrils occasionally reduced to spines). Mesophytic to xerophytic.
Leaves alternate; spiral; petiolate; non-sheathing; simple, or compound; when compound ternate, or palmate. Lamina dissected, or entire; when simple/dissected, palmatifid; usually palmately veined; cross-venulate. Leaves exstipulate; without a persistent basal meristem.
Perianth with distinct calyx and corolla; (6–)10(–12); 2 whorled; isomerous. Calyx (3–)5(–6); 1 whorled; gamosepalous; regular; imbricate, or open in bud. Corolla (3–)5(–6); 1 whorled; polypetalous, or gamopetalous; more or less valvate (supposedly usually, commonly induplicate), or imbricate; regular; green, or white, or yellow, or orange.
Androecium 5 (‘essentially’), or 3 (ostensibly, by reduction and displacement). Androecial members branched and unbranched (commonly there are three stamens, two bifurcated and with two pairs of pollen sacs each, the other unbranched and conventional with two pollen sacs), or unbranched; usually adnate (to the hypanthium); variously coherent (by connate filaments, or in Cucurbita by cohesion of the anthers into a column), or free of one another; when coherent, commonly 1 adelphous (i.e. all the stamens joined in a central column), or 2 adelphous (4/1 in Thladiantha); 1 whorled. Androecium exclusively of fertile stamens. Stamens 3, or 5; reduced in number relative to the adjacent perianth, or isomerous with the perianth. Anthers cohering (commonly), or connivent, or separate from one another; adnate; dehiscing via longitudinal slits; extrorse; unilocular, or unilocular and bilocular (often one unilocular, the others bilocular), or bilocular; bisporangiate, or bisporangiate and tetrasporangiate, or tetrasporangiate; appendaged (via the prolonged connective), or unappendaged. Endothecium developing fibrous thickenings. Microsporogenesis simultaneous. The initial microspore tetrads tetrahedral. Anther wall initially with one middle layer, or initially with more than one middle layer. Tapetum glandular. Pollen grains aperturate; 3 aperturate, or 4–15 aperturate (to ‘many’); variously colpate, or porate, or colporate, or foraminate, or rugate; 2-celled.
Gynoecium 1 carpelled (Cyclanthereae), or (2–)3(–5) carpelled. Carpels reduced in number relative to the perianth. The pistil 1 celled (when monomerous), or 2–3(–5) celled. Gynoecium monomerous, or syncarpous; of one carpel (Cyclanthereae), or synovarious, or synstylovarious, or eu-syncarpous; inferior. Ovary 1 locular, or 2–3(–5) locular (by joining of the usually intruded parietal placentae). Locules secondarily divided by ‘false septa’, or without ‘false septa’. Gynoecium stylate. Styles 1, or 2–3(–5); when more than one, partially joined; apical. Stigmas 1, or 2–3(–5) (one per carpel); commissural; each 2 lobed (in association with the commissural position, suggestive of derivation from adjacent carpels); wet type, or dry type; papillate, or non-papillate; Group II type and Group III type. Placentation parietal (usually); when the ovary plurilocular, axile. Ovules in the single cavity when unilocular, (1–)3–100 (i.e. to ‘many’); when plurilocular (1–)3–50 per locule (?); pendulous, or horizontal, or ascending; non-arillate; anatropous; bitegmic; crassinucellate. Outer integument not contributing to the micropyle. Embryo-sac development Polygonum-type, or Allium-type. Polar nuclei fusing only after one has been fertilized, or fusing simultaneously with the male gamete (?). Antipodal cells formed; 3; not proliferating; ephemeral. Synergids hooked. Hypostase present, or absent. Endosperm formation nuclear. Endosperm haustoria present (usually), or absent; chalazal. Embryogeny onagrad.
Fruit fleshy (usually), or non-fleshy (sometimes); dehiscent (sometimes explosively so), or indehiscent; a berry (usually, most commonly in the form of a ‘gourd’ (pepo) or an amphisarca), or a capsule, or a samara (rarely). Seeds non-endospermic; medium sized to large; often flattened, winged, or wingless. Embryo very well differentiated (the plumule often with clear leaves). Cotyledons 2; flat (flat, often clearly veined). Embryo achlorophyllous (9/11); straight.
