Erythema nodosum is a type of panniculitis that affects subcutaneous fat in the skin, usually first evident as an outcropping of erythematous nodules that are highly sensitive to touch.1 Most nodules are located symmetrically on the ventral aspect of the lower extremities.rythema nodosum nodules vary from 0.4 to 4 inches (1 to 10 cm) in diameter and are poorly demarcated, reflecting their subcutaneous anatomic location (Table 11â4; Figure 1) . Pretibial involvement is most common, although the extensor surfaces of the forearm, the thighs, and the trunk also may be affected.
David Beaulieu. Xeriscape landscaping or, simply, xeriscaping, by definition, is landscaping designed specifically for areas that are susceptible to drought, or for properties where water conservation is practiced. Derived from the Greek xeros meaning dry, the term means literally dry landscape..
Today's waste-efficient landscapes use unthirsty plants--California natives and drought tolerant exotics. Proper soil preparation, garden layout, and planting time assures that plants can mature into beautiful specimens with minimal trimming. In a word, the modern approach to California landscaping is xeriscaping.hile xeriscape translates to mean dry scene, in practice xeriscaping means simply landscaping with slow-growing, drought tolerant plants to conserve water and reduce yard trimmings. The practice of xeriscaping will vary from region to region in California.
