  • Southwestern Rare and Endangered Plants
    Preliminary Report on the Reproductive Biology of the Threatened Chisos Mountain Hedgehog Cactus BONNIE B. AMOS and CHRISTOS VASSILIOU Angelo State University, Texas Abstract: The Chisos Mountain hedgehog cactus (Echinocereus chisoensis, Cactaceae) is a narrow endemic restricted to an approximately 100 square mile area in Big Bend National Park, Texas. It was listed as threatened in 1987 as Echinocereus chisoensis var. chisoensis. An investigation of the reproductive biology and pollination ecology conducted in 1999 and 2000 revealed the taxon to be homogamous, self-incompatible, xenogamous, and heavily dependent upon the cactus oligolectic bee, Diadasia rinconis (Anthophoridae) for pollination. Despite infrequent bee visitation, fruit set from open pollination is high and fruits produce large numbers of seeds. Predation in 2002, probably from rodents as a result of severe drought conditions, was severe on plants, flower buds, and fruits. The Chisos Mountain hedgehog cactus, or Chisos jillo (Opuntia leptocaulis DC.), ocotillo (Fouquieria pitaya (Echinocereus chisoensis W. Marshall), is 1 of splendens K.

Fraga ABSTRACT: We present an annotated catalogue of the vascular flora of the upper Santa Ana River watershed, in the southern San Bernardino Mountains, in southern California. The catalogue is based on a floristic study, undertaken from 2008 to 2010. Approximately 65 team days were spent in the field and over 5,000 collections were made over the course of the study. The study area is ca. 155 km2 in area (40,000 ac) and ranges in elevation from 1402 m to 3033 m. The study area is botanically diverse with more than 750 taxa documented, including 56 taxa of conservation concern and 81 non-native taxa. Vegetation and habitat types in the area include chaparral, evergreen oak forest and woodland, riparian forest, coniferous forest, montane meadow, and pebble plain habitats.

    PART II PERSONAL PAPERS AND ORGANIZATIONAL RECORDS Allen, Paul Hamilton, 1911-1963 Collection 1 RG 4/1/5/15 Photographs, 1937-1959 (1.0 linear feet) Paul Allen was a botanist and plantsman of the American tropics. He was student assistant to C. W. Dodge, the Garden's mycologist, and collector for the Missouri Botanical Garden expedition to Panama in 1934. As manager of the Garden's tropical research station in Balboa, Panama, from 1936 to 1939, he actively col- lected plants for the Flora of Panama. He was the representative of the Garden in Central America, 1940-43, and was recruited after the War to write treatments for the Flora of Panama. The photos consist of 1125 negatives and contact prints of plant taxa, including habitat photos, herbarium specimens, and close-ups arranged in alphabetical order by genus and species. A handwritten inventory by the donor in the collection file lists each item including 19 rolls of film of plant communities in El Salvador, Costa Rica, Honduras, Nicaragua, and Panama. The collection contains 203 color slides of plants in Panama, other parts of Central America, and North Borneo. Also included are black and white snapshots of Panama, 1937-1944, and specimen photos presented to the Garden's herbarium. Allen's field books and other papers that may give further identification are housed at the Hunt Institute of Botanical Documentation. Copies of certain field notebooks and specimen books are in the herbarium curator correspondence of Robert Woodson, (Collection 1, RG 4/1/1/3). Gift, 1983-1990. ARRANGEMENT: 1) Photographs of Central American plants, no date; 2) Slides, 1947-1959; 3) Black and White photos, 1937-44.

    83. South Mountaineer Creek (Mountaineer Creek) (Keeler-Wolf 1991c) Location This candidate RNA (cRNA) lies within the Tule River Ranger District, Sequoia National Forest. It is approximately 37.4 miles (60 km) from the Tule River Ranger Station and within the Golden Trout Wilderness. Its boundaries include all or portions of sections 1, 2, 3, 10, 11, and 14 of T20S, R31E, and sections 35 and 36 of T19S, R31E (36°12'30"N., 118°35'W.), USGS Camp Nelson quad (fig. 165). Ecological subsection – Upper Batholith (M261Eq). Target Element Red Fir (Abies magnifica) Distinctive Features Figure 165—South The area includes several age groups of red fir represented throughout most of Mountaineer Creek the cRNA’s environmental range. Widespread associates of the red fir forest, cRNA such as western white pine (Pinus monticola) and lodgepole pine (Pinus contorta ssp. murrayana), also occur in typical conditions and densities on the cRNA. In addition to the identified target element, well-developed montane meadow and aquatic plant and fauna communities add value to this cRNA. Rare Plants: Two CNPS List 4 species occur in the cRNA. Sierra corydalis (Corydalis caseana ssp. caseana) is locally common and widespread in streamside and rivulet situations at 6900-8600 ft (2103-2621 m). Sierra corydalis is known in the S. Sierra Nevada only from Tulare County. Mineral King Draba (Draba cruciata) is restricted to rocky, N.-facing slopes at the highest elevations beneath open canopies of western white pine and red fir. Its location in the cRNA is within a mile (1.6 km) of the southernmost known occurrence for this taxon.
