  • Cryptic Dioecy of Symplocos Wikstroemiifolia Hayata (Symplocaceae) in Taiwan
    Botanical Studies (2011) 52: 479-491. REPRODUCTIVE BIOLOGY Cryptic dioecy of Symplocos wikstroemiifolia Hayata (Symplocaceae) in Taiwan Yu-Chen WANG and Jer-Ming HU* Institute of Ecology and Evolutionary Biology, National Taiwan University, Taipei 10617, Taiwan (Received November 25, 2010; Accepted March 24, 2011) ABSTRACT. Symplocos wikstroemiifolia Hayata is one of the few morphologically androdioecious spe- cies in Symplocaceae. Although this species has been proposed as cryptically dioecious, little is known about its patterns of sexual expression in the field. We studied the breeding system and reproductive biology of S. wikstroemiifolia in Taiwan. Field investigations showed that anthers of most morphologically hermaphroditic flowers did not produce pollen grains; thus, this flower type should be considered female. Nearly all flowering individuals produced only male or female flowers. The sex ratios were slightly male-biased, but did not sig- nificantly deviate from 1:1, congruent with the proposed cryptic dioecy status. However, two individuals pro- duced flowers that may have been functionally hermaphroditic, suggesting a variation of sexual expression in S. wikstroemiifolia. There were about 12 stamens per male flower but only five staminodes per female flower. No locules and ovules existed in the male flowers, while two locules within the ovary of the female flowers con- tained four ovules each (two large, two small). Male individuals produced cymes and thyrses, whereas female individuals only produced cymes. Some of these morphological characteristics differed from those previously described. Anthesis of most male and female flowers began before dawn and lasted for one to two days. Nev- ertheless, anther dehiscence, which only occurred under dry conditions, was not restricted to a specific time period during the day.

TAYLOR) February, 2017 Southwest Region U.S. Fish and Wildlife Service Albuquerque, NM Tobusch Fishhook Cactus Species Status Assessment - Final Prepared by Chris Best, Austin Ecological Services Field Office, Suggested citation: U.S. Fish and Wildlife Service. 2017. Species status assessment of Tobusch Fishhook Cactus (Sclerocactus brevihamatus ssp. tobuschii (W.T. Marshall) N.P. Taylor). U.S. Fish and Wildlife Service Southwest Region, Albuquerque, New Mexico. 65 pp. + 2 appendices. i Tobusch Fishhook Cactus Species Status Assessment - Final EXECUTIVE SUMMARY Tobusch fishhook cactus is a small cactus, with curved “fishhook” spines, that is endemic to the Edwards Plateau of Texas. It was federally listed as endangered on November 7, 1979 (44 FR 64736) as Ancistrocactus tobuschii. At that time, fewer than 200 individuals had been documented from 4 sites. Tobusch fishhook cactus is now confirmed in 8 central Texas counties: Bandera, Edwards, Kerr, Kimble, Kinney, Real, Uvalde, and Val Verde. In recent years, over 4,000 individuals have been documented in surveys and monitoring plots. Recent phylogenetic evidence supports classifying Tobusch fishhook cactus as Sclerocactus brevihamatus ssp. tobuschii. It is distinguished morphologically from its closest relative, S. brevihamatus ssp. brevihamatus, on the basis of yellow versus pink- or brown-tinged flowers, fewer radial spines, and fewer ribs. Additionally, subspecies tobuschii is endemic to limestone outcrops of the Edwards Plateau, while subspecies brevihamatus occurs in alluvial soils in the Tamaulipan Shrublands and Chihuahuan Desert. A recent investigation found genetic divergence between the two subspecies, although they may interact genetically in a narrow area where their ranges overlap.

The modern native cactus flora includes 35 taxa in 12 genera, plus 2 non-native prickly- pears that are not established in the flora area. The overall cactus flora including fossils and non- natives totals 39 taxa in 13 genera: at least 17 taxa are represented by fossils recovered from packrat middens, two of which are no longer present in the flora area. This account includes selected synonyms, English, Spanish, and O’odham common names in when available, identification keys, brief descriptions, images, local and general distributional, natural history, and ethnobotanical information.

  • Cold Hardy Landscape Cacti & Succulents for Central Texas Jeff
    Cold Hardy Landscape Cacti & Succulents for Central Texas Jeff Pavlat 3/11 The following is a list of recommended landscape plants for Central Texas. Keep in mind that there is a great deal of temperature variation across the region. Temperatures in outlying areas are in some cases 10 to 15 degrees colder than those in town. The cold tolerances listed are approximate. It is important to recognize that there are a number of factors which determine hardiness. Plants placed on south facing slopes receive more solar heat and tend to have a better chance of being undamaged. Plants also fair better with some overhead protection from a tree or shrub. It also helps for them to be placed where they will not receive direct north wind. Generally, low-growing plants receive more ground heat than taller plants and are less likely to freeze. The state of the plant as it enters freezing temperatures is an important factor as well. For instance, many cacti and succulents will endure considerably colder temperatures when dry rather than wet (In fact, cold and wet is often a lethal combination for many cact i). Plants of the same species originating from different parts of the plant’s native range can also result in higher or lower tolerances. It is possible to have two plants of the same species placed side by side and have one freeze, while the other survives. Often some experimentation is necessary to determine what plants will work best for your garden. Cold Hardy Cacti Species (*Texas Native) Common Name Min. Temp.
