The distribution and attributes of selected weeds as hayfever plants

Weeds are probably the most important vascular plants with relation to hayfever. This is because several plant families such as the Chenopodiaceae, Amaranthaceae, Graminae (Poaceae) and Compositae have wide-spread, abundant, anemophylous taxa which occur as major weeds of both agriculture and waste places. Several characteristics will be presented about the ability of these species to be successful in promoting allergies on a international basis. Interestingly, many of these plant species have been included on weed lists of countries whose geography, ecological amplitudes, climates, and agricultural practices are similar. The subsequent reproductive strategy for these species will be reviewed and biological traits discussed with reference to pollen grain production, and dispersal methods or importance as both weeds and hayfever plants.

A 10 year survey of the hay fever plants and important atmospheric allergens in the San Antonio, Texas, metropolitan area

1. 1. A botanical survey of the hay fever plants in the metropolitan area of San Antonio, Texas, is presented. 2. 2. Detailed data are given about the types, abundance, and seasonal occurrence of atmospheric pollens and fungus spores found during a 10 year period of study which was carried out from Jan. 1, 1951, through Dec. 31, 1960, in San Antonio, Texas. 3. 3. Pollens are present in the air over the entire year with the Quercus virginiana (live oak) and the Carya pecan (pecan) being present in large quantities in the spring. The Amaranthus species (careless weed) and grasses, Cynodon dactylon (Bermuda grass) and Sorghum halpense (Johnson grass), appear during most of the year but in largest quantities during the early summer. The Ambrosiae appear in the late summer and fall months. The Juniper sabinoides (mountain cedar) is a heavy pollen contributor during the winter, becoming most important particularly to those migrants who have never been exposed to this toxic pollen. Multiple fungus spores are found in the air during the entire year with spring and fall peaks, which add to the clinical symptoms caused by the pollens. 4. 4. A perennial allergy problem exists in the metropolitan area of San Antonio and is evidenced by the presence of large amounts of allergens and molds in the air throughout the year. The abundance of pollen varies greatly with the prevailing winds and their direction, and the amount of rainfall.

A survey of the hay fever plants and important atmospheric allergens in the Phoenix, Arizona, metropolitan area

1. 1. A botanical survey of the hay fever plants in the metropolitan area of Phoenix, Arizona, is presented. 2. 2. Data are given concerning the kind, concentration, and seasonal occurrence of the atmospheric pollen grains and fungous spores found during a one-year investigation conducted from June 1, 1957, through May 31, 1958, in Phoenix and Tempe, Arizona. 3. 3. Morus species (mulberry) and Fraxinus velutina (Arizona ash) are found to be the most important tree pollinators contaminating the air in the spring. Franseria species (false ragweeds) and Cynodon dactylon (Bermuda grass) are heavy pollinators that reach anthesis in the spring and shed pollen sporadically through the summer and fall. (Contrary to popular belief, only one grass—Bermuda—was found to shed great enough concentrations of pollen to be considered significantly important as a general allergen.) Amaranthus palmeri (careless weed) and Atriplex species (saltbush) are heavy contributors to the atmospheric pollen in the summer and fall months, the careless weed being the most important. Finally, the fungous spores are found in the air year round, with spores of Alternaria species the most prevalent. 4. 4. It is concluded that a definite allergy problem exists in the Phoenix area and the Salt River Valley, as evidenced by the presence of allergens in the air throughout the year.

Hayfever Plants: Their Appearance, Distribution, Time of Flowering and Their Role in Hayfever, with Special Reference to North America (New Series of Plant Science, Vol. 15).

Allergists have indeed been fortunate for many years in having the close cooperation of a botanist of Dr. Wodehouses' caliber and industry. In this book he has gathered the results of a large amount of study concerning the plants which cause hay fever. The first one hundred and sixty-three pages are devoted to a systematic discussion of the grasses, weeds and trees, with many excellent line sketches to aid in identifying the various species. The last third of the book is devoted to regional surveys. The United States is divided into ten regions, and a list of plants and their pollinating times is given for each region. One is impressed by the great variability of flora in the different regions, and particularly by the large number of plants which may cause hay fever in the Southern and in the Southwestern States. Inasmuch as it is necessary for an allergist to

Hay-fever Plants

FOR a plant to be an important cause of hay-fever it must shed its pollen freely, must produce large amounts of pollen, must grow in great abundance, and must have active allergens in the pollen grains. Most wind-pollinated plants satisfy the first condition, but anemophily and entomophily offer little guide to the second. Relative abundance is of immense importance as a distinguishing factor between species of great and small importance in hay-fever; thus only about thirty-five species of grasses out of the thousand or so in the North American flora are important hay-fever plants. Lastly, the allergic qualities of species also differ widely, appearing with fair constancy in the following families: Grarnineae, Compositeae, Chenopodiaceae, Amar-anthaceae, Plantaginaceae, Polygonaceae, Betulaceae, Fagaceae, Ulmaceae, Moraceae, Juglandaceae, Salicaceae, Aceraceae and Oleaceae.

The first report on hay fever in Palestine

The first report on the subject of hay fever in Palestine is submitted. Geographic and climatic peculiarities of the country are described. The most important hay fever plants are enumerated, and their habitat and blossoming time are recorded. The hay fever evinced in this country is solely of the spring type, with the autumnal variety unknown. Of the hay fever-producing plants, the most important is Cynodon dactylon, or Bermuda grass, here known as yablith or indgil. The distribution of hay fever among the Arab population is practically uninvestigated, although other allergic illnesses are frequent. The non-Arab local populations are susceptible to hay fever in the same degree as Europeans. Of the immigrants suffering from the disease, 20 per cent comprise those who had previously suffered from the disease and were attacked in the first year of local residence; 45 per cent remained unaffected for two or three years and were then attacked; 10 per cent remained unaffected for six or more years before being attacked; and 25 per cent of patients of the immigrant group were attacked by the disease for the first time in Palestine, with no previous history of hay fever.
