Plants ABSTRACT Currently, beekeeping contributes in the economic development of many countries. This agricultural activity has gained more attention in various countries during the last few years, and beekeeping activities are increasing rapidly in Oman. The availability of many food sources to honey bees is very essential for the development of beekeeping. Thus, listing potential honey bee plants is very essential to help boosting beekeeping. In this paper, previous studies on honey bee plants in Oman as well as potential honey bee plants are reviewed. In fact, few studies have been conducted on bee plants in Oman. A good number of plant species including fruits, field crops, vegetables and wild plants that can feed honey bees were surveyed as shown in this review. The flowering period of these plants can cover the whole year. This study can be considered as an essential step towards understanding the bee flora in Oman.

Dillman, Ecologist USDA Forest Service, Tongass National Forest [email protected] Vascular Plants of Negelle-Borona, Ethiopia, USFS IP Introduction This report provides supplemental information to the Inventory and Assessment of Biodiversity report prepared for the US Agency for International Development (USAID) following the 2011 mission to Negelle- Borona region in southern Ethiopia (Dillman 2012). As part of the USAID supported Pastoralist Livelihood Initiative (PLI), this work focused on the biodiversity of the kallos (pastoral reserves). This report documents the vascular plant species collected and identified from in and around two kallos near Negelle (Oda Yabi and Kare Gutu). This information can be utilized to develop a comprehensive plant species list for the kallos which will be helpful in future vegetation monitoring and biodiversity estimates in other locations of the PLI project. This list also identifies plants that are endemic to Ethiopia and East Africa growing in the kallos as well as plants that are non-native and could be considered invasive in the rangelands. Methods Field work was conducted between November 28 and December 9, 2011 (the end of the short rainy season). The rangeland habitats visited are dominated by Acacia and Commifera trees, shrubby Acacia or dwarf shrub grasslands.

Gabel1, R.R. Wise1,*, G.K.

Each cystolith is contained within a cell Acanthaceae called a lithocyst. In leaves, lithocysts may be found in the mesophyll or the epidermis. A study by Koch et al.

We report herein that such ‘channel cells’ in the Acanthaceae are actu- leaf epidermal impression ally lithocysts containing fully formed cystoliths in which only a portion of the lithocyst is exposed at the epidermis, lithocyst forming a leaf epidermal impression. Intact leaves and isolated cystoliths from 28 Acanthaceae species (five in the non-cystolith clade and 23 in the cystolith clade) were examined using light and scanning electron microscopy and X-ray microanalysis. All 23 members of the cystolith clade examined contained cystoliths within lithocysts, but not all showed leaf epidermal impressions. In four species, the lithocysts were in the leaf mesophyll, did not contact the leaf surface, and did not participate in leaf epidermal impression formation. The remaining 19 species had lithocysts in the epidermis and possessed leaf epidermal impressions of differing sizes, depths and morphologies.

The origin of fire-adapted lineages is a long-standing question in ecology. Although phylogeny can provide a significant contribution to the ongoing debate, its use has been precluded by the lack of comprehensive DNA data. Here we focus on the ‘underground trees’ (= geoxyles) of southern Africa, one of the most distinctive growth forms characteristic of fire-prone savannas. 2. We placed geoxyles within the most comprehensive dated phylogeny for the regional flora comprising over 1400 woody species.

  • BOTANY SECTION Compiled by Richard E. Weaver, Jr., Ph.D., and Patti J
    TRI-OLOGY, Vol. 47, No. 3 Patti J. Anderson, Ph.D., Managing Editor MAY-JUNE 2008 DACS-P-00124 Wayne N. Dixon, Ph. D., Editor Page 1 of 20 BOTANY SECTION Compiled by Richard E. Weaver, Jr., Ph.D., and Patti J. Anderson, Ph.D. For this period, 155 specimens were submitted to the Botany Section for identification, and 1,595 were received from other sections for identification/name verification for a total of 1,750. In addition, 19 specimens were added to the herbarium. Some of the samples received for identification are discussed below: Chrysopsis latisquamea Pollard. (A genus of eleven species endemic to the southeastern United States). Compositae/Asteraceae. Scrubland goldenaster. The goldenasters, with their profusion of yellow flower heads in late summer and fall, are conspicuous components of the vegetation of sunny, dry open habitats through much of northern and central Florida. All eleven species in the genus are native to Florida, and nine are endemic to the state. Three of these (a fourth may only be a subspecies of another species) are included on Florida’s endangered list. This species is common in pinewoods and oak scrub on the peninsula from Highlands County north. It is a biennial or a short-lived perennial from a basal rosette, with a solitary, erect stem 40-70 cm tall. The leaves are grayish with densely long-woolly pubescence. Like all of the goldenasters, the flower heads have bright yellow ray flowers and yellow disks as well. This one is distinctive in that the phyllaries (involucral bracts) are densely glandular, and their tips are expanded and somewhat leaflike.
