Evaluation Of Two Methods For Estimating Belowground Production In The Great Dismal Swamp, Millie Symbula
Evaluation Of Two Methods For Estimating Belowground Production In The Great Dismal Swamp, Millie Symbula
Biological Sciences Theses & Dissertations
Two methods were used to estimate belowground production in a maple-gum stand in the seasonally flooded Great Dismal Swamp of Virginia. The first was an auger method which involved sequential core sampling. The second method was an implanted soil mass technique. Nylon mesh bags were filled with peat and buried at the study site. New growth into these implants was taken to be production.
Mean annual lateral root biomass and necromass to 40 cm, determined from soil cores, were 583 g·m-2 and 281 g·m-2, respectively. Production estimates for roots ≤ 5 mm in diameter, using soil cores, …

The Identity Of The Genus Neowawraea (Euphorbiaceae), W. John Hayden
Biology Faculty Publications
On the basis of newly acquired morphological evidence gathered in the course of floristic studies, the monotypic genus Neowawraea Rock is now recognized as a species of Flueggea Willd. and is renamed F. neowawraea W. J. Hayden. Taxonomic documentation presented for F. neowawraea includes an expanded morphological description, a map showing its widely scattered distribution in the Hawaiian Islands to which the species is endemic, and discussions of type specimens, common names, and its extreme rarity. The combination of flowers in pedicellate axillary clusters, the lobed staminate disk, pistillode, extrorse anthers, hemitropous ovules, and, especially, the smoothish dry seeds with …

Anatomy And Affinities Of Penthorum, Melanie Lynn Haskins, W. John Hayden
Anatomy And Affinities Of Penthorum, Melanie Lynn Haskins, W. John Hayden
Biology Faculty Publications
The genus Penthorum L. consists of two species of perennial herbs, P. sedoides of eastern North America and P. chinense of eastern Asia. Penthorum has long been considered intermediate between Crassulaceae and Saxifragaceae. An anatomical study of both species was undertaken to contribute to a better understanding of the relationships of these plants. Prominent anatomical features of Penthorum include: an aerenchymatous cortex and closely-spaced collateral vascular bundles of stems; one-trace unilacunar nodes; brochidodromous venation, rosoid teeth bearing hydathodes, and anomocytic stomata of leaves; angular vessel elements with many-barred scalariform perforation plates and alternate to scattered intervascular pits; thin-walled nonseptate fiber-tracheids; …

Wood Anatomy Of Nolanaceae, Sherwin Carlquist
Wood Anatomy Of Nolanaceae, Sherwin Carlquist
Aliso: A Journal of Systematic and Floristic Botany
Wood of seven collections of six species of Nolana, a genus (18 spp.) of the central western coast of South America was studied for quantitative and qualitative features. The wood is ring porous, with moderately wide vessels bearing simple perforation plates and alternate pits with some grooves interconnecting slitlike pit apertures. Imperforate tracheary elements are fiber-tracheids with vestigial borders on pits or libriform fibers; vasicentric tracheids (reported for Nolanaceae for the first time) are present in varying numbers. Axial parenchyma is vasicentric scanty (sometimes absent), sometimes with tangential bands that may be terminal in part. Rays are both multiseriate and …
Wood Anatomy Of Martniaceae And Pedaliaceae, Sherwin Carlquist
Wood Anatomy Of Martniaceae And Pedaliaceae, Sherwin Carlquist
Aliso: A Journal of Systematic and Floristic Botany
Quantitative and qualitative features are reported for one species of Martynia (Martyniaceae) and for seven species of six genera of Pedaliaceae. The inclusion of woody annuals as well as of shrubs provides a broader picture ofPedaliaceae than hitherto available. The wood features of Martyniaceae and Pedaliaceae (listed in the Systematic Conclusions) are compatible with placement of these families in Scrophulariales (Bignoniales). Ifindividual features of the two families are compared with those of other families of the order, however, no one family can be cited as more closely related to Martyniaceae and Pedaliaceae than any other. Martyniaceae is not necessarily the …
Systematics Of Nama (Hydrophyllaceae): Seed Coat Morphology Of Lemmonia Californica Ajd Nama Species Allies With Nama Demissum, John D. Bacon
Systematics Of Nama (Hydrophyllaceae): Seed Coat Morphology Of Lemmonia Californica Ajd Nama Species Allies With Nama Demissum, John D. Bacon
Aliso: A Journal of Systematic and Floristic Botany
Seed coat morphology of Lemmonia californica. long held to be a relative of Nama, was examined using scanning electron microscopy. Its seed coat exhibits reticulum cells with undulate cell walls and columnar radial wall thickenings. Seed coat structure in nine species of Nama, N. demissum, N. aretioides, N. densum, N. parviflorumm, N. pusillum, N. depressum, N. dichotomum, N. sericeum and N. origanifolium, members forming one of six seed groups in Nama, also exhibit reticulum cells with undulate walls and columnar wall thickenings. The Nama species and Lemmonia are remarkably similar in testa organization, suggesting that the relationship …
A New Species Of Carex (Cyperaceae) From Western South America And A New Combination In The Genus, Gerald A. Wheeler
A New Species Of Carex (Cyperaceae) From Western South America And A New Combination In The Genus, Gerald A. Wheeler
Aliso: A Journal of Systematic and Floristic Botany
A new species of Carex (Cyperaceae) is described from western South America. Carex pleioneura (sect. Foetidae) occurs in central Chile and west-central Argentina, where it grows on rocky slopes, among rocks bordering streams, and in mountain meadows (vegas). A new combination in South American Carex. C. longii var. meridionalis (sect. Ovales), is also made here.
