Of the patients referred to a dermatologist for generalized pruritus with no apparent primary cutaneous cause, 14 to 24 percent have a systemic etiology. In the absence of a primary skin lesion, the review of systems should include evaluation for thyroid disorders, lymphoma, kidney and liver diseases, and diabetes mellitus. Findings suggestive of less seri- ous etiologies include younger age, localized symptoms, acute onset, involvement limited to exposed areas, and a clear association with a sick contact or recent travel. Chronic or general- ized pruritus, older age, and abnormal physical findings should increase concern for underly- ing systemic conditions.

NHESP is responsible for the conservation and protection of hundreds of species that are not hunted, fished, trapped, or commercially harvested in the state. The Program's highest priority is protecting the 176 species of vertebrate and invertebrate animals and 259 species of native plants that are officially listed as Endangered, Threatened or of Special Concern in Massachusetts. Endangered species conservation in Massachusetts depends on you! A major source of funding for the protection of rare and endangered species comes from voluntary donations on state income tax forms.

A new species is easily distinguished from the other species of the genus in Indo-China in having short petioles less than 4 mm long, obovate-oblong or oblong-elliptic leaf blade with rounded to slightly cordate base, and 18–24 pairs of secondary veins. Keywords: flora, Indochina, Sapindales, taxonomy Introduction The genus Gluta Linnaeus (1771: 293) is trees or rarely shrubs of Aacardiaceae distributed from Madagascar, India, Myanmar, Indo-China, Thailand, to throughout Malesia (Kochummen 1996, Chayamarit 2010). It consists of about 30 species, among which four species have been known from Laos: G. cambodiana Pierre (1897: 368), G. laccifera (Pierre 1885: 538) Ding Hou (1978a: 14), G. tavoyana Wallich ex Hooker (1879: 22) and G. usitata (Wallich 1829: 29) Ding Hou (1978a: 21) (Tardieu-Blot, 1962, Newman et al. 2007, Chayamarit 2010, Gardner et al. 2015).

  • Biology Habitat Management Options Weeds: Poison Ivy and Poison Oak
    Page: 1 (revision date:4/7/2021) Weeds: Poison ivy and Poison oak(Toxicodendron spp. (Rhus spp.)) family: Anacardiaceae cycle Perennial plant type: Broadleaf Use Integrated Pest Management (IPM) for successful plant problem management. Biology Western poison ivy (Toxicodendron rydbergii) is a woody shrub or occasionally a climbing woody vine that may reach 3 to 9 feet. Pacific poison oak (T. diversilobum) is a woody vine reaching several yards in length, or occasionally a shrub to 6 feet. Leaves of both consist of three leaflets on a long petiole. The two side leaflets have short stalks, the center leaflet has a longer stalk. While poison ivy leaflets are sharply pointed at the tips, poison oak leaflets have wavy or lobed margins with rounded tips and lateral leaflets may lack stalks. Young leaves are shiny red, while older leaves are glossy green. Leaf undersides are lighter green with a coat of velvety hairs. The foliage is strikingly colored in the fall. Flowers occur in clusters on slender stems in the axils of the alternate leaves. The greenish-white blossoms are about 1/4 inch across. The ridged, berrylike fruits are greenish and resemble tiny pumpkins when immature. At maturity, they are cream-colored to whitish, reaching about 1/4 inch across. Plants reproduce by seeds and creeping root systems. SPECIAL INFORMATION: An irritant oil is present in all parts of the plant, including the roots. The oil is also present in dried plant tissues. Contact may result in a severe skin rash. Wash with COLD water and soap after contact. Smoke from burning plants may also carry the oil.
