    • Yam (Bot) A large, esculent, farinaceous tuber of various climbing plants of the genus Dioscorea; also, the plants themselves. Mostly natives of warm climates. The plants have netted-veined, petioled leaves, and pods with three broad wings. The commonest species is Dioscorea sativa, but several others are cultivated.
    • Yam (Bot) Any one of several cultural varieties of the sweet potato.

  • Interesting fact: What is the difference between a yam and a sweet potato? According to the Mayo Clinic dietician, a true yam is a large, starchy root that can get up to 100 pounds. It is native to Africa and Asia and is seldom available in the USA. The sweet potato is a native American plant. It was a staple for early settlers and was actually brought to Europe by Columbus. There are two varieties of sweet potatoes: One is moist and orange-fleshed, the other is drier and yellow. The orange-fleshed potato is commonly - and incorrectly - called a yam. This common practice has resulted in confusion when it comes to labels. Some stores incorrectly label the darker of the two sweet potatoes as being a yam, and they list the nutrient content for yams. True yams have no vitamin A. So consumers mistakenly think that the product has no vitamin A, even though it actually does. Consumers are most likely eating sweet potatoes - and sweet potatoes are rich in vitamin A, vitamin C and fiber.
    • n yam A tuberous root of a plant of the genus Dioscorea, particularly if belonging to one of numerous species cultivated for their esculent roots; also, such a plant itself. The plant is commonly a slender twining high-climbing vine, in some species prickly; the root is fleshy, often very large, sometimes a shapeless mass, sometimes long and cylindraceous, varying in color from white through purple to nearly black. The yam is propagated by cuttings from the root, or also in some species by axillary bulblets. The root contains a large amount of starch, sometimes 25 per cent., is hence highly nutritious, and in tropical lands largely takes the place of the potato of temperate climates. It lacks, however, the dry mealiness of the potato, and is on the whole rather coarse, and not as a rule highly esteemed by people of European races. It is cooked by baking or boiling, and is in the West Indies sometimes converted into a meal used for making cakes and puddings. D. sativa is an ordinary species (the hoi of the Hawaiians) with unarmed stem and an acrid root which requires soaking before boiling; it is a profitable source of starch. D. alata, the red or white yam, the uvi of the Fiji Islands, has a winged, not prickly stem, supported in culture by reeds; its tubers attain sometimes a length of 8 feet and a weight of 100 pounds. D. aculeata, the kawai of the Fijis, has prickly stems not requiring support. D. Batatas, the Chinese or Japanese yam, is hardy in temperate climates, and excited considerable interest in Europe and America, at the time of the potato-rot, as a possible substitute for that crop. The tuber is pure-white within, of a flaky consistency, and of a taste agreeable to many. It grows 3 feet deep, however, enlarging somewhat toward the bottom, hence is very difficult to gather. D. sativa also is hardy in the southern United States, but the true yam is there little cultivated. (See def. 2.) These species present many varieties, and various other species are more or less cultivated.

Complex Systems
While core-collapse SNe trace the SFH within ∼ 107 years of the SN explosion, SNe Ia are connected to the SFH through a delay time dependent on the formation mechanism for SNe Ia (for example, see Madau et al. (1998), Gal-Yam & Maoz (2004), and Strolger et al. (2004)).
Rates and Progenitors of Type Ia Supernovae
More generally, the relationship between the core-collapse and SN Ia rates provides insight into the initial mass fraction, chemical evolution, and star formation rate and history of galaxies (Madau et al. 1998; Maoz & Gal-Yam 2004).
