The Flora Of Greater San Quintín, Baja California, Mexico (2005–2010), Sula E. Vanderplank
The Flora Of Greater San Quintín, Baja California, Mexico (2005–2010), Sula E. Vanderplank
Aliso: A Journal of Systematic and Floristic Botany
The plants of San Quintín (Baja California, Mexico) were documented through intensive fieldwork and collection of herbarium specimens to create a checklist of species. The region is located near the southernmost extent of the California Floristic Province, and the flora is influenced by the adjacent desert to the south. A total of 435 plant taxa were documented, of which 82% are native plants. Almost one in three native plant taxa in Greater San Quintín is a sensitive species, here documented as rare and/or locally endemic, and many taxa have yet to be evaluated fully for rarity and threats. Four major …
A New Variety Of Lomatium Ravenii (Apiaceae) From The Northern Great Basin And Adjacent Owyhee Region, Kimberly M. Carlson, Donald H. Mansfield, James F. Smith
A New Variety Of Lomatium Ravenii (Apiaceae) From The Northern Great Basin And Adjacent Owyhee Region, Kimberly M. Carlson, Donald H. Mansfield, James F. Smith
Aliso: A Journal of Systematic and Floristic Botany
Variability in the group of Lomatium species comprising L. nevadense, L. ravenii, and L. foeniculaceum has led to conflicting classification schemes. While some taxonomists have treated L. ravenii as a distinct species made up of all the populations from California, Nevada, Idaho, and Oregon, others considered L. ravenii to be nothing more than a morphological extreme of L. nevadense. We examined morphological and phylogenetic data from across the range of L. ravenii, concluding that variation in the species warrants varietal distinction. Non-metric multidimensional scaling analysis of 29 populations shows two distinct groups—one from the vicinity of …

Sinker Structure Of Phoradendron Californicum (Viscaceae) Confounds Its Presumed Close Relationship To Other Acataphyllous Species, Rudolf Schmid, Clyde L. Calvin, Carol A. Wilson
Sinker Structure Of Phoradendron Californicum (Viscaceae) Confounds Its Presumed Close Relationship To Other Acataphyllous Species, Rudolf Schmid, Clyde L. Calvin, Carol A. Wilson
Aliso: A Journal of Systematic and Floristic Botany
Phoradendron is the largest genus of New World mistletoes, with about 250 species in two subgenera, Boreales and Aequatoriales, corresponding, respectively, to northern acataphyllous and southern cataphyllous groups. The typically acataphyllous P. californicum of western North America is controversial because recent phylogenetic work has nested it in the southern cataphyllous clade. Seedling establishment, stem anatomy, and endophytic system structure of this species were studied. Seedling haustorial holdfasts have gland cavities, structures considered absent in the Viscaceae clade of Santalales. The stem epidermis has a thick cuticle, deeply sunken stomata, and branched multicellular trichomes. The stem has an outer cortex …
Phylogenetic Evaluation Of Series Delimitations In Section Palmata (Acer, Aceroideae, Sapindaceae) Based On Sequences Of Nuclear And Chloroplast Genes, Jianhua Li
Aliso: A Journal of Systematic and Floristic Botany
Acer section Palmata (Japanese maples) is the largest section within the genus; however, series delimitations within section Palmata have not been evaluated in a phylogenetic context. Both maximum parsimony and maximum likelihood analyses of DNA sequence data of nuclear rDNA ITS and chloroplast genes (ndhF, trnL-trnF, and psbA-trnH) from 23 species of Acer section Palmata show that traditional series do not form individual clades. Results from this study support the most recent taxonomic treatment of Acer that does not recognize any series in section Palmata. Nuclear and chloroplast phylogenies are significantly …
Nomenclatural Changes For Some Grasses In California. Ii., James P. Smith Jr., J. Travis Columbus
Nomenclatural Changes For Some Grasses In California. Ii., James P. Smith Jr., J. Travis Columbus
Aliso: A Journal of Systematic and Floristic Botany
Two additional nomenclatural changes are required for Poaceae treatments that will appear in the second edition of The Jepson Manual: Higher Plants of California. They are Elymus x gouldii and Festuca temulenta. The former corrects a violation of the rule in the International Code of Botanical Nomenclature involving the naming of hybrids, and the latter involves a widely occurring non-native grass in California traditionally assigned to Lolium.

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.

Distribution And Regional Ecology Of Californian Palm Oases Interpreted From Google Earth Images, Richard A. Minnich, Ernesto Franco-Vizcaíno, Mario Salazar-Ceseña
Aliso: A Journal of Systematic and Floristic Botany
The native fan palms of the Baja California peninsula (Mexico) and neighboring southern California (USA) comprise two species each in Washingtonia and Brahea. While these are among the most familiar ornamental palms in the world, many features of their taxonomy, distribution, and environmental relationships remain unresolved. We utilized Google Earth Digital Globe imagery (and limited surveys by air and land) to develop the first map detailing the geographic distribution of palm populations in the Peninsular Range Province (PRP) and used these data to formulate new hypotheses on their biotic and abiotic relationships. We inventoried 15,216 populations covering an area …

Phylogenetic Relationships Between Malcolmia, Strigosella, Zuvanda, And Some Closely Related Genera (Brassicaceae) From Turkey Revealed By Inter-Simple Sequence Repeat Amplification, Beki̇r Doğan, Murat Ünal, Fevzi̇ Özgökçe, Esra Marti̇n, Ayla Kaya
Phylogenetic Relationships Between Malcolmia, Strigosella, Zuvanda, And Some Closely Related Genera (Brassicaceae) From Turkey Revealed By Inter-Simple Sequence Repeat Amplification, Beki̇r Doğan, Murat Ünal, Fevzi̇ Özgökçe, Esra Marti̇n, Ayla Kaya
Turkish Journal of Botany
The genus Malcolmia W.T.Aiton is taxonomically problematic, and some of its species have recently been transferred to the genera Strigosella Boiss. and Zuvanda Dvorák. Three species of this genus are native to Turkey. The revision studies based on molecular data, which were collected in the past few years, display the phylogenetic relations and the systematic positions of the taxa more reliably and apparently. Thus taxonomic problems of species are resolved through DNA-based molecular analyses, which are not affected by environmental factors compared to phenotypic studies. In the present study, the amplifications of the DNA fragments were carried out using ISSR …

Fruit And Seed Morphology Of The Fumaria L. Species (Papaveraceae) Of Iran, Fatemeh Ebrahimzadeh Araii, Maryam Keshavarzi, Masoud Sheidaii, Parinaz Ghadam
Turkish Journal of Botany
The macro and micro fruit and seed morphology and surface ornamentations of 21 populations of 6 Fumaria L. species were investigated using stereomicroscope and scanning electron microscopy. These data are shown to support data from the general morphology. The results indicate that the fruit and seed characters of the genus Fumaria are valuable for taxonomic applications and are useful for classification. F. officinalis show a different shape in their fruit. The close relationships are observed for F. parviflora and F. vaillantii. F. indica, as a hybrid between F. asepala and F. parviflora, shows intermediate micro-morphological features.

Evaluation Of The Horticultural Traits Of Genus Alstroemeria And Genus Bomarea (Alstroemeriaceae), Yukiko Kashihara, Koichi Shinoda, Naho Murata, Hajime Araki, Yoichiro Hoshino
Turkish Journal of Botany
We investigated the flower characteristics of 7 Alstroemeriaceae plants - 5 Alstroemeria L. species and 2 Bomarea Mirb. species. The flower and tepal sizes, and tepal colours were compared. The flower shape in Alstroemeria psittacina Lehm. was found to be similar to that in Bomarea coccinea (Ruiz & Pav.) Baker. The length/width ratio of B. salsilla (L.) Mirb. was intermediate compared with that of the other species. These preliminary data will be useful in selecting wild species in order to examine interspecific or intergeneric hybridisations in the breeding of Alstroemeriaceae plants.
