A new subspecies of the plains pocket gopher (Geomys bursarius ozarkensis), located in the Ozark Mountains of north central Arkansas, was recently described by Elrod et al. (2000). Current range for G. b. ozarkensis was established, habitat preference was assessed by analyzing soil samples, vegetation and distance to stream and potential pocket gopher habitat within the current range was identified. A census technique was used to estimate a total density of 3, 564 pocket gophers. Through automobile and aerial survey 51 known fields of inhabitance were located extending the range slightly. Soil analyses indicated loamy sand as the most common texture with a slightly acidic pH and a broad range of values for other measured soil parameters and 21 families of vegetation were identified. All inhabited fields were located within an average of 107.2m from waterways and over 1,600 hectares of possible suitable habitat was identified.

Plunkett Abstract—Four new Brazilian species from the genus Paspalum are described and illustrated: P. phaeotrichum, P. vexillarium, P. veredense, and P. clipeum. Paspalum phaeotrichum is an annual with no obvious affinity to any known species of Paspalum, although it shares several characters with species of both P. subg. Ceresia and the ’Bertoniana’ group. Paspalum vexillarium is presumably related to P. ceresia, with which it has been confused. Paspalum veredense shows affinities with both P. ellipticum and P. erianthoides. Paspalum clipeum is probably related to annual species of the ’Plicatula’ group, although it lacks the dark brown upper florets typical of that group. Moreover, P. spissum, a species currently considered as a synonym under P.

Paspalum is a rather large genus “numbering nearly 400” species (Chase, 1929). Sour paspalum (Paspalum conjugatum) stands by itself in this genus as suggested by Chase (1929) who created for it, alone, the Section Conjugata (Fig. 1). Its most unusual character is the vigorously stoloniferous habit allowing, at times, for a rapidly formed perennial ground cover. Sour paspalum has been assumed to be native where it occurs in the Americas, from Florida to Texas and southward to Peru, Bolivia, and northern Argentina, from sea level to 4,000 ft elevation. The grass was first described from a specimen collected in Surinam (Dutch Guiana). Sour paspalum has been assumed, however, to be intro- duced wherever it occurs in the Old World tropics (Fig. 2) and Pacific Islands. The early trade routes were between Australia, Singapore, and Africa. Probably both carpetgrass (Axonopus compressus) and sour paspalum, being of similar distribution and ecology, were spread at the same time to the same places.

    MAG NO UA ISSUE 80 Magnolia dianica 'Michelle' tsyn: Michelia yunnanensis 'Michelle'J Tony Avent Photographs by the author My October tgg6 trip to Yunnan, China got off to a lackluster start as we spent the first day in the pouring rain at the Western Hills Preserve above Kunming. Although the skies cleared for our sec- ond day, the flora was depauperate as we headed west of Kunming, toward Dali, on the main highway connecting the two towns. We made our first stop in a small cemetery one hour west of Kunming at 6, sooft (tgggm) elevation. The purpose of this stop was to exam- ine a large tree of the rare Crtlocedrus rnacrdlepis. Our guide, Dr. Guan Kayun from the Kunming Institute of Botany, explained that, in this region, the only trees and native flora remaining were in cemeteries due to the overabundance of agrarian activities. rIIImer'S Cartable where parenr plant was found nsua 80 MAGNOUA As we passed the caretak- ers' quarters, which were near- ly obscured by racks of drying corn, we spotted the Calocedrus. While everyone was admir- ing the Calocedrus, I spied three, Sft (s.Sm) tall stunted plants of Magnolia dianica. .. obviously munched on by yaks or a sim- ilar herbivore. I noticed that leaves were somewhat small- er and the plants more com- pact than the plants that I had seen in the trade. Obviously, this could be due to the stressed environmental conditions un- der which it was growing. I looked the plant over for seed, but it wasn't until I got on my knees did I find six old seeds on the ground underneath the plants.

  • Potomac Valley & MAC
    Potomac Valley & MAC ARS - North Carolina Nursery Trip March 2 – March 4, 2017 It is nice to get away in March for a gardening outing. For over a decade, members of the Potomac Valley Chapter and Middle Atlantic Chapter ARS have been heading down to North Carolina to visit some mail order nurseries that have open houses at that time of year. We buy some plants, socialize, go out to dinner, and have a lot of fun. George McLellan and some other members of MAC will be leaving on Thursday to stay that night at the Best Western Hotel in Danville, VA. The next morning, they will pick up a wholesale order from Cam Too Camellia Nursery in Greensboro, one of the largest wholesale camellia growers in the US. With 30 acres of hoop houses, it is not a place to tour or make on-site selections. Orders must be placed in advance which we could do sometime. Before getting to Cam Too, George expects to visit nearby Buds and Blooms Nursery, another wholesale nursery that grows woody plants including hydrangeas, crape myrtles, azaleas, kalmia, and a limited number of rhododendrons. After that, they will head to Camellia Forest Nursery and then continue south to Sanford. They will have to miss Pine Knot Farms on Friday, but it may be possible for them to stop by there on Saturday afternoon if they have time. We all intend to convene on Friday night in Sanford, NC, but we are not exactly sure which motel we will use. Last year we stayed at the Baymont Inn but some rooms had problems.

Shade affects turf quality by reducing light for photosynthesis. The shade tolerance of the tropical grasses, Digitaria longiflora and Axonopus compressus were evaluated against Stenotaphrum secundatum (St. Augustinegrass). The grasses were established under shade structures that provide 0%, 50%, 75% or 90% shade level for 30 days. A suite of leaf traits, recorded from similar leaf developmental stage, displayed distinct responses to shade conditions. Leaf length, relative to control, increased in all three species as shade level increased. The mean leaf extension rate was lowest in St. Augustinegrass (80.42%) followed by A.
