Flora Of Richmond National Battlefield Park, Virginia, W. John Hayden, Melanie Lynn Haskins, Miles F. Johnson, James M. Gardner

Biology Faculty Publications

An inventory of the vascular flora of nine of eleven units of Richmond National Battlefield Park was compiled from 1985 to 1987. Each site was visited during the growing season in two to four week intervals; plant species were identified and recorded in the field and/or collected for later study. A total of 761 different species were identified in the surveyed units, and 2487 individual records of species per particular park unit were noted. Twenty-three percent of the flora consists of exotic species, largely from Eurasia. Voucher specimens are housed in the herbaria of the University of Richmond and Virginia …

Winter Habitats And Foods Of Blue Grouse In The Sheeprock Mountains, Utah, Peter J. Perkins, Frederick G. Lindzey, Jay A. Roberson, Gregory Mcdaniel, Randy Berger

Great Basin Naturalist

Winter habitat use and food habits of Blue Grouse (Dendragapus obscurus) were studied in an isolated Utah desert mountain range that contained little typical Douglas-fir (Pseudotsuga menziesii) winter habitat. Habitat use was concentrated in the Douglas-fir and pinyon (Pinus edulis)–juniper (Juniperus spp.) habitat. Douglas-fir and pinyon pine were the most consumed foods. Other foods that represented >15% of the composition of an individual fecal sample were limber pine (Pinus flexilis), mahogany (Cercocarpus ledifoliu), juniper, and an Anteunaria–Cirsium type. The breadth in winter diet indicates that Blue Grouse may …

Changes In Mule Deer Size In Utah, Dennis D. Austin, Robert A. Riggs, Philip J. Urness, David L. Turner, John F. Kimball

Great Basin Naturalist

Trends in age-specific, eviscerated carcass weights were determined for hunter-harvested yearling and two-year-old buck mule deer. Carcass weights declined over an 11-year period from two areas of similar management, but with independenly collected data sets. Carcass weights also declined between the opening and second weekends of the hunt. Management implications are discussed.

Wood Anatomy And Relationships Of Montinia, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

Quantitative and qualitative data are presented on wood anatomy of root, basal stem, and upper stem of Montinia caryophyllacea. Anatomy of twig wood of Kaliphora madagascariensis is compared with these results, as is the data of Ramamonjiarisoa (1980) on wood of the genus Grevea. Features common to the three genera in wood as well as other portions of the plant are reviewed; these are consistent with the interpretation that Montinia and Kaliphora are very close to each other, despite previous positions of the two genera in Saxifragaceae and Comaceae, respectively. Grevea, although more distant from Montinia than …

Assessing The Utility Of Isozyme Number For Determining Ploidal Level, Loren H. Rieseberg, Douglas E. Soltis

Aliso: A Journal of Systematic and Floristic Botany

In order to evaluate the utility of isozyme number for estimating ploidal level in ancient polyploid (paleopolyploid) plant species, isozyme number was determined for species of the putatively paleopolyploid genus Helianthus with n = 17, and compared with those of a species of Heliomeris with n = 8. Electrophoretic examination of 13 enzymes revealed the presence of nine duplicated isozymes in Helianthus annuus and Helianthus bolanderi and six duplicated isozymes in Heliomeris multiflora. Thus, there is little difference in isozyme number between ploidal levels. It is suggested that the lack of strong concordance between isozyme number and ploidal level …

Follar Flavonoids Of Keckiella Ternata, Ron Scogin

Aliso: A Journal of Systematic and Floristic Botany

The major foliar phenolics of Keckiella ternata are quercetin 3-O-glucoside, kaempferol 3-O-glucoside, and acteoside (= orobanchin). The occurrence of flavonols in K. ternata is anomalous compared with other species of Keckiella and Penstemon, in which leaf flavonoids are based on luteolin and 6-hydroxyluteolin. The occurrence of foliar flavonols in K. ternata is interpreted as an advanced, derived condition.

Taxonomy And Natural History Of Hydnora (Hydnoraceae), Lytton J. Musselman, Johann H. Visser

Aliso: A Journal of Systematic and Floristic Botany

Hydnora is a genus of subterranean holoparasitic herbs found in arid and semiarid regions of Africa, Madagascar, and the southwestern part of the Arabian peninsula. Results from field and herbarium studies suggest the genus consists of four or five species, although more than 12 have been described. The recent rediscovery of H. triceps, a plant that had remained uncollected for a century, supports the need for additional field work. Taxonomic research has been impeded by a paucity of collections, which are often fragmentary in nature and poorly preserved. Supraspecific classification, species complexes, floral biology, and uses are discussed.

Allozyme Variation In Hellianthus Praecox Ssp. Hirtus, A Rare Sunflower From Southern Texas, Loren H. Reiseberg, Michael F. Doyle

Aliso: A Journal of Systematic and Floristic Botany

Allozyme data were used to evaluate the genetic status of a rare endemic sunflower from Texas, Helianthus praecox ssp. hirtus. Comprising approximately 200 plants, the taxon is presently known from a single population in the Carrizo Springs region of Southern Texas. Electrophoretic examination of 17 enzyme loci revealed that ssp. hirtus is genetically similar to, but distinct from, the two more widespread subspecies of H. praecox: ssp. praecox and ssp. runyonii. Levels of genetic variation in the single population of ssp. hirtus (P = 0.4 7, A = 1.88, and H = 0.17) are similar to those …

Wood Anatomy Of Tasmannia, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

Quantitative and qualitative data are presented for 11 collections of eight taxa. Diameter and length of tracheids are related to plant size, but populations in cooler locations have narrower and shorter tracheids than one would expect on the basis of plant size and age, and smaller tracheids are believed to be of selective value in these environments because of their resistance to embolisms. Vesturing is absent from tracheids in taxa from warmer localities but pronounced in colder places; this, too, is a probable mechanism for resistance to embolism formation. Helical thickenings are reported for one collection of T. insipida; …

Photosynthesis Of Arid And Subtropical Succulent Plants, Irwin P. Ting

Aliso: A Journal of Systematic and Floristic Botany

The hypothesis of Crassulacean acid metabolism (CAM) is that it is a physiological adaptation to arid or otherwise dry habitats. Stomata are closed during the day and open at night when the evaporative demand is low. Thus exogenous CO₂ is fixed at night with relatively little water loss. CAM is typically found in succulents occurring in desert and dry Mediterranean regions, but not in the cold deserts of Asia. Recently, it has become known that many arid tropical succulent plants are CAM as well, particularly those growing epiphytically. The vegetation of St. John, U.S. Virgin Islands, ranges from desertlike …

The Streptanthus morrisonii complex is a six-taxon group of closely related serpentine rock outcrop endemics from Lake, Napa, and Sonoma counties of California, USA. Two new subspecies (S. morrisonii subsp. kruckebergii and S. brachiatus subsp. hoffmanii) from Lake County, California, are described. The relationship of these taxa to others in the section is reviewed and descriptions and a key are provided.

Wood Anatomy Of Cercidium (Fabaceae), With Emphasis On Vessel Wall Sculpture, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

Quantitative and qualitative data are presented for wood anatomy of the seven species of Cercidium (including two subspecies of C. floridum as well as the hybrid C. x sonorae) currently recognized. Data on wood of Parkinsonia are presented for purposes of comparison. Vessel walls of Cercidium show unusual sculpture: coarse excrescences termed verrucae here, crateriform pits, and grooves interconnecting pit apertures. These plus crystal distribution, presence of septa in fibers, pit diameter, presence of vasicentric tracheids, and presence of diagonal vessel aggregations are probably species distinctions to various degrees. The crystal-bearing fibers of Cercidium, some of which have …

Leaf Anatomy Of The Goetzeaceae, Scott Zona

Aliso: A Journal of Systematic and Floristic Botany

A comparative study of the leaf anatomy ofthree species of three genera of Goetzeaceae (Henoonia, Goetzea, and Espadaea) revealed a number of characteristics common to all genera, viz. anomocytic stomata, sinuous anticlinal epidermal walls, both glandular and uniseriate nonglandular trichomes, crystal sand and druses in the mesophyll (often in the same cell), and intraxylary phloem. The mid veins of these species exhibit secondary growth and parenchymatous rays. The unifying anatomical features of this family are, however, not uncommon in the Solanaceae. The results of this study support placement of the Goetzeaceae in or very near Solanaceae. …
