  Xanthosoma - Wikipedia, the free encyclopedia
Xanthosoma is a genus of about 50 species of tropical and sub-tropical arums in the flowering plant family, Araceae, all native to tropical America.
Xanthosoma is also grown as a crop in the Philippines.
Xanthosoma starch is highly hypoallergenic due to the small size of the starch grains.

Xanthosoma will grow well in a variety of soils but will do best in loose, fertile, well drained soil that has been heavily amended with organic material.
Xanthosoma are native to tropical and semi-tropical North and South American countries.
When planting xanthosoma tubers, they should be watered sparingly until the young shoots have formed leaves - tuber rot can result from excessive cold, damp soil conditions that can occur when the roots are not developed enough to remove moisture from the soil.

 Tannia, Yautia
The usable parts in both species are the subterranean tuberous stems which, in the case of the latter, contain between 15 and 39 percent of carbohydrates, 2 to 3 percent of protein and 70 to 77 percent of water; both have a nutritional value comparable to the potato and are probably easier to digest.
The Xanthosoma species are plants of the tropical rain forest and, although in their natural habitat they grow under the forest canopy, under cultivation they are usually sown with full exposure to sunlight.
Xanthosoma cultivars have been described on the basis of collections established in Puerto Rico and Trinidad and Tobago, with indigenous or introduced materials.

Xanthosoma species are native to the American tropics and belong to the same family as the taro (Colocasia esculenta), a plant from the Old World.
After Xanthosoma was introduced to the South Pacific by botanists in the early 1900s, yet another batch of names arose.
Yautia/malanga blanca (Xanthosoma sagittifolium) is the most common variety found in the US and varies from a light, earthy, and waxy form to mild and smooth.

Xanthosoma sagittifolium (L.) Schott, commonly called cocoyam or tannia, is a tropical root crop widely distributed in West Africa, tropical America and Asia (Duru and Uma, 2002).
In addition, use of protein rich products as animal feed would release widely used feed materials such as soy meal, fish protein, cotton seed flour, protein isolates and peanut meal for human consumption in areas where conventional human food stuffs are in short supply (Joglekar et al., 1983).
Each was dissolved in 200 ml of water and Xanthosoma solid process waste added to it gradually until the one litre mark is reached in a beaker.

 GROWTH AND DEVELOPMENT OF XANTHOSOMA AND COLOCASIA SPP. UNDER DIFFERENT SPACINGS
Dry matter production and distribution were studied in the cocoyams (Xanthosoma sitifolium and Colocasia esculenta) for 2 yr at 3 spacings of 1 x 1 m, 1 x 0.75 m, and 1 x 0.50 m.
Monthly plant samples were taken after 12 wk and the leaf and stalk areas, leaf area index, number of leaves, and dry weights of different plants parts determined.
Dry matter production in Xanthosoma reached a peak around the 24th wk and then began to decline, but in Colocasia there was no clear-cut trend in total dry matter yield.

 Some functional properties of starches isolated from tropical aroids.   (Site not responding. Last check: 2007-10-20)
Xanthosoma sagittifolium, Colocasia esculenta, and Ipomoea batata plants produce underground storage organs that contain mainly starch and fiber.
The availability of these tropical and subtropical crops in the temperate zones of the world has increased in recent years with improvements in agronomic and genetic techniques.
In this study the gelatinization profiles of starches isolated from Xanthosoma sagittifolium, Colocasia esculenta, and Ipomoea batata storage organs were evaluated using changes in the heat flow or enthaphy during the gelatinization process by differential scanning calorimetric (DSC) method.

Addition of (NH Cl, and urea to  Xanthosoma  solid process waste increased the growth rate of mutant, with the highest  increase observed  with urea.  Medium amended with urea also had the highest protein level of 26.23% strain compared to a protein yield of 17.41% obtained in the control with no added nitrogen.
The peeled cormels were washed, cut into small pieces, blended for 3 min and the resulting slurry sieved with a muslin cloth.  The filtrate was a starch-rich suspension that yielded domestic or industrial starch.

As a rule of thumb, xanthosomas will have a sagittate leaf blade (there are a few exceptions to this) with a smooth, sometimes waxy upper surface and thick ribs on the lower surface, often quilted at the veins.
There are many edible forms of Xanthosoma sold in the US under the blanket common name of malanga.

Xanthosoma is a genus in the Caladium Alliance in the Tribe Caladieae, Family Araceae.
For Colocasia and Alocasia -- the botanical difference is based on the number and placement of ovules (female goodies) on the inflorescence (bloom thingie) and the only foliar distinction is that sometimes Alocasia leaves are sometimes pinnatifid (sort of fernlike, or like Stangeria in Cycadacea, or arrow shaped)
Xanthosoma blooms are quite different from Colocasia or Alocasia especially with respect to the female parts and Xanthosoma also produces sterile flowers between the male and female ones.
