Germination in the Cypripedium/Paphiopedilum Alliance
Germination in the Cypripedium/Paphiopedilum Alliance The colourful temperate ladyslippers including Cypripedium acaule, calceolus and reginae have attracted the attention of many investigators attempting to solve the problem of germinating the recalcitrant seeds (Arditti, 1967; Arditti et al, 1982; Curtis, 1942; Oliva and Arditti, 1984; Stoutamire, 1974, 1983; Withner, 1953). Germination of Cyp. reginae seed has perhaps attracted the most attention given that this species is particularly showy. Harvais (1973, 1974, 1980, and 1982) was the first Canadian investigator to approach the problem of axenic culture. He succeeded not only in germinating the seeds of Cyp. reginae but also in producing leafy seedlings. His death in 1982 cut short a promising research program and was a great loss. Frosch (1986) outlined a procedure to asymbiotically germinate and grow Cyp. reginae to flower in three years. More recently, Ballard (1987), has presented detailed results of his experiments in the sterile propagation of the same species, using seeds taken at early stages of development and at maturity. Of particular interest was his discovery that dormancy in Cyp. reginae seeds can be broken by refrigeration of the seeds at 5/C for two to three months prior to incubation at room temperature. He has achieved from 19–98% germination after three to four months using Knudson's “C” medium (Knudson, 1946) with seed taken 42 to 60 days after pollination. Cypripedium calceolus is a particularly attractive species, native to both North America and Europe. Carlson (1940) examined the formation of the seed of Cyp. parviflorum to gain a better understanding of the problems involved in germination. -

GENOME EVOLUTION in MONOCOTS a Dissertation
GENOME EVOLUTION IN MONOCOTS A Dissertation Presented to The Faculty of the Graduate School At the University of Missouri In Partial Fulfillment Of the Requirements for the Degree Doctor of Philosophy By Kate L. Hertweck Dr. J. Chris Pires, Dissertation Advisor JULY 2011 The undersigned, appointed by the dean of the Graduate School, have examined the dissertation entitled GENOME EVOLUTION IN MONOCOTS Presented by Kate L. Hertweck A candidate for the degree of Doctor of Philosophy And hereby certify that, in their opinion, it is worthy of acceptance. Dr. J. Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field. -

Sugarberry Plant Fact Sheet
Plant Fact Sheet Wildlife: Many species of songbirds including SUGARBERRY mockingbirds and robins eat the fruit and use the tree for nesting habitat. It is a larval and nectar host for two Celtis laevigata Willd. butterflies: hackberry emperor (Asterocampa celtis) and Plant Symbol = CELA American snout (Libytheana carineta). White-tailed deer browse the leaves and fruit. Contributed by: USDA NRCS Plant Materials Program Other Uses: Sugarberry is used for furniture, athletic goods, firewood, and plywood. It has limited use for flooring, creating, and for wood posts. It is used as an ornamental and as a street tree in residential areas in the lower South Status Please consult the PLANTS Web site and your State Department of Natural Resources for this plant’s current status (e.g. threatened or endangered species, state noxious status, and wetland indicator values). Description and Adaptation Sugarberry is a native tree that can grow up to 80 feet in height and up to 3 feet in diameter. It is a short lived tree, probably living not more than 150 years. It has a broad crown formed by spreading branches that are often drooped. The bark is light gray in color and can be smooth or covered with corky warts. The branchlets are covered with short hairs at first and eventually they become smooth. The leaves are alternated, simple, and slightly serrate. The leaves are 2-4 inches long and 1 to 2 Robert H.

Polyploidy in Trema (Ulmaceae)
1971 341 Polyploidy in Trema (Ulmaceae) A. S. Hans1,2,3 Panjab University, Botany Department, Chandigarh 14, India ReceivedDecember 18, 1969 Introduction Trema Lour. belongs to Ulmaceae, a small family of trees and shrubs, encompassing 15 genera and about 150 species (Lawrence 1951) in tropics and subtropics of both the hemispheres. Trema is a small genus composed of 30 tropical species of which only three species constitute the Indian flora. The members of the Ulmaceae show variation in basic chromosome number. Celtis is polybasic with x=10, 11, and 14 (Darlington and Wylie 1955), while Ulmus, Holoptelea and Zelkovia exhibit a uniform base number of 14. A few instances of inter and intraspecific polyploidy in Celtis and Ulmus exist in nature. Celtis australias has been reported to be a tetraploid (2n=40), while C. laevigata, C. sinensis, and C. occidentalis are diploid, all with 2n=20 (Bowden 1945). The report of 2n=28 in C. occidentalis (Sax 1933) is suggestive of aneuploid races in the species. Most of the species of Ulmus are diploid except U. americana where in addition to the diploid race (Krause 1930), a tetraploid race is also known (Sax 1933). Artificial triploids and tetraploids have been raised in U. glabra by Ehrenberg (1945). The two chromosomally known species of Trema exhibit variable numbers. T. orientalis has been reported to have n=18 (Arora 1960) from Banglore and n=20 (Gajapathy 1961) from Madras in South India; T. politoria has n=10+B (Mehra and Gill). In view of the discordant reports on the chromosome number (n=18, 20) in Trema orientalis, the cytological study was undertaken to ratify the chromosome number, to assess the incidence of polyploidy, and if possible to determine the base number of this small genus. -
Cypripedium Parviflorum Salisb
Cypripedium parviflorum Salisb. synonym: Cypripedium calceolus L. var. parviflorum (Salisb.) Fernald yellow lady's-slipper Orchidaceae - orchid family status: State Threatened, USFS sensitive rank: G5 / S2 General Description: Perennial with showy flowers; stems 7-70 cm tall, sparsely pubescent, somewhat glandular. Leaves several, alternate, bases slightly sheathing the stem, broadly elliptic to elliptic-lanceolate, 6-17 x up to 7 cm, lightly pubescent, usually glandular. Floral Characteristics: Flower 1 (rarely 2), terminal, subtended by an erect, leaflike bract. Sepals and petals greenish or yellowish, often marked with dark reddish brown or purplish spots, blotches, or streaks. Upper sepal broadest, 19-80 x 7-40 mm; the lateral pair of sepals completely fused or with only a notch at their tip. Petals somewhat narrower and longer than the sepals, 24-97 x 3-12 mm, often wavy-margined and spirally twisted. Lip strongly pouched, 15-54 mm long, pale to deep yellow (rarely white), sometimes with reddish or Illustration by Jeanne R. Janish, purplish spots around the orifice. Flowers May to June. ©1969 University of Washington Press Fruits: Ellipsoid to oblong-ellipsoid capsules. Identif ication Tips: Cypripedium montanum has a white lip, rarely suffused with magenta. It may hybridize with C. parviflorum, resulting in individuals with very pale yellow lips. The habitat of C. montanum is typically well-drained upland, while that of C. parviflorum is wetland/riparian or the ecotone between wetland and upland. Two varieties, var. makas in and var. pubes cens , are both reported from WA ; their relative abundance and distribution is under review. Range: East of the C ascade crest in B.C ., WA , and O R, to the eastern U.S.
