Ballard, H.E., Jr., D.S. Feller, and G.L. Nesom. 2004. Cliff Cudweed at specific rank in Pseudognaphalium (Asteraceae: Gnaphalieae). Sida 21:777-780.
Tiny plants endemic to cliff faces and crevices in Wisconsin have been treated as a variety of a common and widespread species. The authors present evidence and a rationale for treating the Wisconsin endemic as a separate species.
Beck, J.B., G.L. Nesom, P.J. Calie, G.I. Baird, R.L. Small, and E.E. Schilling. 2004. Is subtribe Solidagininae (Asteraceae) monophyletic? Taxon 53:691-698.
The 190 species in 24 genera closely related to goldenrods (the genus Solidago) can be clearly divided into two groups, but neither morphological traits nor molecular (DNA) comparisons are effective in determining conclusively that these two groups are most closely related to each other.
Bletter, N., J. P. Janovec, B. Brosi, and D. C. Daly. 2004. A digital base map for studying the neotropical flora. Taxon 53(2): 469-477.
The authors provide an overview of a digital base map for studying the Neotropical flora. The base map is derived from GIS data sets from Environmental Systems Research Institute (ESRI), Woods Hole Research Center, U.S. Geological Survey and World Wildlife Fund. The map can be downloaded free with permission from the authors from the following website: http://www.nybg.org/bsci/digital_maps/.
Chocce, M., J. Janovec, and E.A. Christenson. 2004. A synopsis of the genus Otostylis (Orchidaceae: Maxillarieae subtribe Zygopetalinae) with a new record from southern Peru. Sida 21:841-852.
The taxonomy of this orchid genus is summarized. The 4 species occur in South America and Trinidad; Otostylis lepida is a distinct species and a new record for Peru, where it is a dominant herb in bog wetlands of the Madre de Dios area.
Janovec, J. P. and R. Garcia. 2004. Myristicaceae in the Encyclopedia of Forest Science. Elsevier Press, London.
An overview of the Myristicaceae is provided with information about the taxonomy, morphology, distribution, ecology, and economic importance of the family.
Kaufman, G.E., G.L. Nesom, A.S. Weakley, T.E. Govus, and L.M. Cotterman. 2004. A new species of Symphyotrichum (Asteraceae: Astereae) from a serpentine barren in western North Carolina. Sida 21:827-840.
An unusual blue-rayed aster in the mountains of southwestern North Carolina has been known for more than two decades - it finally is described as a species new to science. It grows in an unusual habitat in the Nantahala National Forest.
Kral, R. 2004. An evaluation of Anthenantia (Poaceae). Sida 21:293-310.
Anthenantia is a genus of grass species endemic to the southeastern USA. Kral refines the definitions of the species and their distribution and describes a new species (Anthenantia texana), increasing the total for the genus to three.
McLemore, C., G.C. Kroh, and J.E. Pinder III. 2004. Juniperus ashei (Cupressaceae): physiognomy and age structure in three mature Texas stands. Sida 21:1107-2004.
Ash juniper is abundant in Texas and provides significant habitat for rare species, but mature intact stands of the juniper are relatively rare. A study of structural and age-related characteristics of the species provides information relevant to conservation and management decisions.
Majestyk, P. and J. Janovec. 2004. Contributions to the moss flora of the Amazonian lowlands of Madre de Dios, Peru. Sida 21:1231-1238.
Recent collections of mosses in the Madre de Dios area of southeastern Peru include 58 species, 54 of which are new to the area and 4 of which are new to Peru.
Nesom, G.L. 2004. Taxonomic reevaluations in North American Erigeron (Asteraceae: Astereae). Sida 21:19-40.
Four daisy fleabanes of the western USA are treated as full species rather than as "varieties," and clarifications in the definitions of various other species are provided. A new variety of Erigeron clokeyi is described, and a new name is provided for a California species that was earlier recognized by a name that had already been used in the genus (and was thus invalid).
Nesom, G.L. 2004. Notes on typification in Pluchea (Asteraceae: Plucheeae). Sida 21:59-64.
In order to clearly establish the identity of various names used for species of North American Pluchea (camphorweed), the author associates a particular herbarium specimen with each of the names. This is not something that was consistently done for old names (most pre-1900), but it is required for new ones.
Nesom, G.L. 2004. Notes on the distribution of Pseudognaphalium luteoalbum (Asteraceae: Gnaphalieae). Sida 21:463-464.
This species of cudweed (sunflower family) is first reported from Louisiana, and its early introductions to Oregon, Washington, New York, and Pennsylvania, probably through ship ballast, is documented.
Nesom, G.L. 2004. New records of Erigeron (Asteraceae) for Nevada. Sida 21:473-474.
Erigeron nanus is first reported for Nevada, and additional collections of Erigeron eatonii verify its existence there and broaden its known range.
Nesom, G.L. 2004. New distribution records for Gamochaeta (Asteraceae: Gnaphalieae) in the United States. Sida 21:1175-1186.
Various state records are reported for species of Gamochaeta (cudweed). Two of the species are first reported for the USA. For the 12 species of the genus known from the USA, a hypothesis of nativity is given, with acknowledgement that because the species tend to be extremely weedy, it is difficult to be certain of their native area.
Nesom, G.L. 2004. New species of Gamochaeta (Asteraceae: Gnaphalieae) from the eastern United States and comments on similar species. Sida 21:717-742.
Two new species of Gamochaeta (cudweed) are described from the eastern USA. One occurs abundantly in at least 19 states, and the other is known from 9 states. Both tend to be weeds of roadsides and other 'weedy' sites, and it is possible that both species may be native to South America, where they also have been previously undetected.
Nesom, G.L. 2004. Erigeron peregrinus and Erigeron glacialis (Asteraceae: Astereae). Sida 21:665-672.
A daisy fleabane widespread and common in high elevation habitats of western North America is treated as a full species (E. glacialis). Since 1943 it has been regarded as a subspecies of E. peregrinus, but even where the two species come into close contact, reproductive isolation holds them as two distinct and recognizable entities.
Nesom, G.L. 2004. Generic placement of Chaptalia hintonii (Asteraceae: Mutisieae). Sida 21:929-934.
In a 1998 publication, Argentinian botanist Katinas placed the Mexican species Chaptalia hintonii in the otherwise Old World genus Gerbera. The author takes issue with her judgement and gives evidence supporting the continued treatment of C. hintonii within Chaptalia, where its closest relatives are classified.
Nesom, G.L. 2004. Response to "The Gerbera complex (Asteraceae, Mutisieae): to split or not to split" by Liliana Katinas. Sida 21:941-942.
In this friendly exchange, the author makes a response to Katinas's rebuttal to his challenge (above).
Nesom, G.L. 2004. Pseudognaphalium canescens (Asteraceae: Gnaphalieae) and putative relatives in western North America. Sida 21:781-790.
Five species of cudweeds mostly centered in California have been recently treated (in the Jepson Manual) as subspecies of a single species. Evidence is presented for regarding each of them as a separate species, Pseudognaphalium thermale is brought into the genus with a new combination, and distribution maps and a key are included.
Nesom, G.L. 2004. Asteraceae from wool mill sites in South Carolina, including new records for North America. Sida 21:1215-1224.
Documentation is given for 73 species of Asteraceae collected in 1957-1960 from around wool mills in South Carolina - the seeds arrived in wool to be cleaned and processed. 45 of these species are first reports or first documentation for the flora of South Carolina. Six are first reports for North America and are species native to South America and Australia.
Nesom, G.L. and D.F. Murray. 2004. Notes on North American arctic and boreal species of Erigeron (Asteraceae: Astereae). Sida 21:41-58.
Definitions are clarified for various high-latitude North American species of daisy fleabane. The occurrence of Erigeron ochroleucus in Alaska is recognized, disjunct more than 2800 kilometers from its closest localities to the south. Erigeron porsildii, mostly from Alaska and Yukon, is recognized as a species new to science.
Nesom, G.L. and T.W. Nelson. 2004. A new species of Erigeron (Asteraceae: Astereae) from northwestern California. Sida 21:673-678.
Erigeron maniopotamicus, a white-rayed fleabane species new to science, grows in the Mad River region of northwestern California.
Nesom, G.L. and J.M. Stucky. 2004. Taxonomy of the Liatris pilosa (graminifolia) group (Asteraceae: Eupatorieae). Sida 21:815-826.
The older name Liatris pilosa replaces L. graminifolia for a common species of the Atlantic coastal plain. Relationships among L. pilosa and its three closest relatives are clarified and a taxonomic summary is provided, including nomenclature, distribution maps, ecological summaries, and a key.
O'Kennon, R.J. and C. McLemore. 2004. Schoenoplectus hallii (Cyperaceae), a globally threatened species new for Texas. Sida 21:1201-1204.
This little bulrush sedge has been discovered along the moist sandy-clay margins of small ponds in the LBJ National Grasslands in Wise County, the first known occurrence of the species in Texas. It also is rare elsewhere, with known localities scattered through a few other states in the eastern USA.
Phipps, J.B. and R.J. O'Kennon. 2004. A review of Crataegus series Rotundifoliae (Rosaceae) in western Canada. Sida 21:65-78.
The names and definitions are reviewed for a group of hawthorn species from Alberta and British Columbia - including a new species and new variety. O'Kennon and Canadian collaborator Phipps have made collections and observations in this area over a number of summers and know these little trees in great detail.
Pruski, J.F. and G.L. Nesom. 2004. Gamochaeta coarctata, the correct name for Gamochaeta spicata (Asteraceae: Gnaphalieae). Sida 21:711-716.
The nomenclatural history of this little cudweed is complex and has been confused - the authors lay out the details.
Rolfsmeier, S.B. and G.L Nesom. 2004. New records for Pseudognaphalium (Asteraceae: Gnaphalieae) in California and Nebraska. Sida 21:1205-1208.
Documentation is given for first reports of the occurrence of various species in these states. Pseudognaphalium jaliscense, a species known only from Mexico prior to 2001, is now known from 12 counties in Nebraska.
Trivedi, M. R., F. H. Cornejo, and A. R. Watkinson. 2004. Seed predation on Brazil Nuts (Bertholletia excelsa) by Macaws (Psittacidae) in Madre de Dios, Peru. Biotropica 36(1): 118-122.
The authors report results of a study of the impact of feeding behavior of macaws on fruits and seeds of Brazil nut trees in the southeastern Peruvian Amazon.
Singhurst, J.R., R.J. O'Kennon, and W.C. Holmes. 2004. The genus Prenanthes (Asteraceae: Lactuceae) in Texas. Sida 21:181-192.
The authors review the Texas species of Prenanthes (sunflower family) and describe a new one - Prenanthes carrii, named for the Texas Nature Conservancy's Bill Carr, who has contributed much to knowledge of the regional flora. The species is known from only a few localities in the Edwards Plateau region.
Weakley A.S. and G.L. Nesom. 2004. A new species of Ptilimnium (Apiaceae) from the Atlantic coast. Sida 21:743-752.
An inconspicuous but highly distinctive new species of the carrot family is described. It is known from localities in Georgia, South Carolina, and North Carolina, where it occurs on the edges of tidal freshwater marshes.
