Robert F. Thorne, distinguished botanist and former curator of the herbarium at Rancho Santa Ana Botanic Garden, left a rich botanical legacy. Contributions featured include a list of his articles appearing in Aliso: A Journal of Systematic and Evolutionary Botany, as well a list of plant taxa named for him.
Ponderosa Pine Revisited, J. Robert Haller, Nancy J. Vivrette
Ponderosa Pine Revisited, J. Robert Haller, Nancy J. Vivrette
Aliso: A Journal of Systematic and Floristic Botany
We here recognize a new variety, Pinus ponderosa var. pacifica, in the Pacific portion of the species' distribution and present a new combination for Washoe pine as a variety, Pinus ponderosa var. washoensis. In this treatment, we reject the neotype of Pinus ponderosa selected by Lauria and designate instead the branch collected by David Douglas with mistletoe (Arceuthobium campylopodum) as lectotype for Pinus ponderosa. Table 1 compares the distinguishing characters of the North Plateau (typical) variety, the Pacific variety, and the Washoe variety of Pinus ponderosa with a closely related species, Pinus jeffreyi.

Two New Combinations In Western North American Asteraceae, David J. Keil
Two New Combinations In Western North American Asteraceae, David J. Keil
Aliso: A Journal of Systematic and Floristic Botany
Two new combinations that will be used in the second edition of The Jepson Manual are proposed for western North American Asteraceae: Helianthus petiolaris subsp. canescens and Cirsium scariosum var. loncholepis.
Nomenclatural Changes For Some Grasses In California And The Muhlenbergia Clade (Poaceae), J. Travis Columbus, James P. Smith Jr.
Nomenclatural Changes For Some Grasses In California And The Muhlenbergia Clade (Poaceae), J. Travis Columbus, James P. Smith Jr.
Aliso: A Journal of Systematic and Floristic Botany
New combinations and names are here validated for ten grass (Poaceae) taxa in California for the forthcoming revision of The Jepson Manual. In addition, guided by recent molecular phylogenetic studies, ten non-California grass species are here transferred to Muhlenbergia (Chloridoideae: Cynodonteae) to achieve monophyly of the genus. Lolium, long known to be phylogenetically nested within Festuca, is here subsumed into Festuca, and the circumscription of Stipa is expanded to include all Stipeae (native and non-native) in California. In Stipeae, most currently recognized genera are not monophyletic. Attaining monophyly while bearing in mind identification for persons not expert …
Classification And Biogeography Of Panicoideae (Poaceae) In The New World, Fernando O. Zuloaga, Osvaldo Morrone, Gerrit Davidse, Susan J. Pennington
Classification And Biogeography Of Panicoideae (Poaceae) In The New World, Fernando O. Zuloaga, Osvaldo Morrone, Gerrit Davidse, Susan J. Pennington
Aliso: A Journal of Systematic and Floristic Botany
Panicoideae (Poaceae) in the New World comprise 107 genera (86 native) and 1357 species (1248 native). As circumscribed herein, Panicoideae include eight tribes: Andropogoneae, Arundinelleae, Centotheceae, Gynerieae, Isachneae, Paniceae, Steyermarkochloeae, and Thysanolaeneae. The two major tribes are Andropogoneae with 230 species (16.95% of all New World panicoids), and Paniceae with 1082 species (79.73%). Andropogoneae are divided into nine subtribes (Andropogoninae, Anthistiriinae, Coicinae, Germainiinae, Ischaeminae, Rottboelliinae, Saccharinae, Sorghinae, and Tripsacinae), while Paniceae are divided into seven subtribes (Arthropogoninae, Cenchrinae, Digitariinae, Melinidinae, Panicinae, Paspalinae, and Setariinae). Brazil is the center of diversity of New World panicoids with 741 species (54.6% of all …
Classification And Biogeography Of New World Grasses: Chloridoideae, Paul M. Peterson, J. Travis Columbus, Susan J. Pennington
Classification And Biogeography Of New World Grasses: Chloridoideae, Paul M. Peterson, J. Travis Columbus, Susan J. Pennington
Aliso: A Journal of Systematic and Floristic Botany
Subfamily Chloridoideae (Poaceae) in the New World includes 72 genera (61 native, 11 introduced), 678 species (607 native), and, including intraspecific taxa, 817 total taxa. The five largest genera are Muhlenbergia (147 species), Eragrostis (111), Sporobolus (76), Bouteloua (57), and Chloris (35). Three tribes are recognized in this study: Cynodonteae, Eragrostideae, and Zoysieae, with ten, three, and two subtribes, respectively. Cynodonteae, the largest tribe, comprise 58 genera and 451 species (67% of all New World chloridoids), including 25 genera (98 species, 22% of all New World Cynodonteae) with unknown affinities (incertae sedis). In Mexico, the USA, and Canada there are …
Classification And Biogeography Of New World Grasses: Anomochlooideae, Pharoideae, Ehrhartoideae, And Bambusoideae, Emmet J. Judziewicz, Lynn G. Clark
Classification And Biogeography Of New World Grasses: Anomochlooideae, Pharoideae, Ehrhartoideae, And Bambusoideae, Emmet J. Judziewicz, Lynn G. Clark
Aliso: A Journal of Systematic and Floristic Botany
Molecular data support Anomochlooideae and Pharoideae as the two most basal extant clades within Poaceae. Anomochlooideae are endemic to the New World and have two tribes and two genera including the widespread Streptochaeteae (3–4 spp.) and the critically endangered Anomochloeae (1 sp.) of coastal Bahia, Brazil. Pharoideae are pantropical with one tribe, three genera, and 14 species; all eight species of Pharus occur only in the New World. Bambusoideae and Ehrhartoideae are sister groups and together form a clade sister to Pooideae, although support for this set of relationships is low. Ehrhartoideae are a worldwide subfamily represented in the New …
