  • Origin and Age of Australian Chenopodiaceae

Using a previously published rbcL phylogeny of the Amaranthaceae–Chenopodiaceae alliance (Kadereit et al. 2003) and new ITS phylogenies of the Camphorosmeae and Salicornieae, we conclude that Australia has been reached in at least nine independent colonization events: four in the Chenopodioideae, two in the Salicornieae, and one each in the Camphorosmeae, Suaedeae, and Salsoleae. Where feasible, we used molecular clock estimates to date the ages of the respective lineages. The two oldest lineages both belong to the Chenopodioideae (Scleroblitum and Chenopodium sect. Orthosporum/Dysphania) and date to 42.2–26.0 and 16.1–9.9 Mya, respectively. Most lineages (Australian Camphorosmeae, the Halosarcia lineage in the Salicornieae, Sarcocornia, Chenopodium subg. Chenopodium/Rhagodia, and Atriplex) arrived in Australia during the late Miocene to Pliocene when aridification and increasing salinity changed the landscape of many parts of the continent. The Australian Camphorosmeae and Salicornieae diversified rapidly after their arrival. The molecular-clock results clearly reject the hypothesis of an autochthonous stock of Chenopodiaceae dating back to Gondwanan times.

More than 150 species occur worldwide, although dodder is most prevalent in the Americas. The genus Cuscuta is in the Cuscutaceae family, but sometimes it is included in the family Convolvulaceae (morning glories). Dodder species vary in the number of different host species they can infect. Some, such as C. salina, are in rather restricted sites such as salty marshes, flats, and ponds on just a few host plant species. Others, such as C. pentagona (C. campestris in some publications), are found on many crop and weed species including alfalfa, asparagus, melons, safflower, sugarbeet, tomato, field bindweed (Convolvulus arvensis), lambsquarters (Chenopodium album), and pigweed (Amaranthus species). C. indecora, also has a wide host range that includes alfalfa and weeds such as field bindweed, five-hook Dodder, Cuscuta species, on bassia (Bassia hyssopifolia), lambsquarters, and Russian thistle (Salsola tragus). tomato. Japanese dodder, C. japonica, which is native to Asia, recently has been found in California attacking and covering ornamental shrubs and fruit trees, with a Table 1.

MELVIN USDA Natural Resources Conservation Service Central National Technology Support Center 501 W. Felix Street, Bldg. 23 Fort Worth, Texas 76115-3404 ABSTRACT The U.S. Army Corps of Engineers (Corps) administers the National Wetland Plant List (NWPL) for the United States (U.S.) and its territories. Responsibility for the NWPL was transferred to the Corps from the U.S. Fish and Wildlife Service (FWS) in 2006. From 2006 to 2012 the Corps led an interagency effort to update the list in conjunction with the U.S. Environmental Protection Agency (EPA), the FWS, and the USDA Natural Resources Conservation Service (NRCS), culminating in the publication of the 2012 NWPL. In 2013 and 2014 geographic ranges and nomenclature were updated. This paper presents the fourth update of the list under Corps administration. During the current update, the indicator status of 1689 species was reviewed. A total of 306 ratings of 186 species were changed during the update.
