Harry L. Arnold, Jr., once initiated a report of a dermatitisproducing plant with the whimsical statement: "The list of plants capable of producing dermatitis venenata is already so long that it seems quite possible that only time is needed for it to include all known plants. The report of the observation of this property in one more plant, therefore, would seem to require some justification other than the fact that the plant has not been previously identified as a common cause of dermatitis." 1 The justification for a regional report on dermatitis-producing plants is not to benefit those in practice in the area, where most plant offenders are well known, but because of the increasing tendency (1) for tropical plants to be transported year-round into areas where they are unfamiliar or (2) for patients to return home from the subtropical regions with a plant-induced dermatitis. Table 1 lists plants associated with dermatitis in south Florida and Hawaii. Although there is much similarity in the plants in these two areas, there is a greater diversity in Hawaii because its mountains will support more temperate plants. It is interesting that, in each location, almost all dermatitis-producing plants have been introduced and are not originally native. |
