Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE
Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE LILIACEAE de Jussieu 1789 (Lily Family) (also see AGAVACEAE, ALLIACEAE, ALSTROEMERIACEAE, AMARYLLIDACEAE, ASPARAGACEAE, COLCHICACEAE, HEMEROCALLIDACEAE, HOSTACEAE, HYACINTHACEAE, HYPOXIDACEAE, MELANTHIACEAE, NARTHECIACEAE, RUSCACEAE, SMILACACEAE, THEMIDACEAE, TOFIELDIACEAE) As here interpreted narrowly, the Liliaceae constitutes about 11 genera and 550 species, of the Northern Hemisphere. There has been much recent investigation and re-interpretation of evidence regarding the upper-level taxonomy of the Liliales, with strong suggestions that the broad Liliaceae recognized by Cronquist (1981) is artificial and polyphyletic. Cronquist (1993) himself concurs, at least to a degree: "we still await a comprehensive reorganization of the lilies into several families more comparable to other recognized families of angiosperms." Dahlgren & Clifford (1982) and Dahlgren, Clifford, & Yeo (1985) synthesized an early phase in the modern revolution of monocot taxonomy. Since then, additional research, especially molecular (Duvall et al. 1993, Chase et al. 1993, Bogler & Simpson 1995, and many others), has strongly validated the general lines (and many details) of Dahlgren's arrangement. The most recent synthesis (Kubitzki 1998a) is followed as the basis for familial and generic taxonomy of the lilies and their relatives (see summary below). References: Angiosperm Phylogeny Group (1998, 2003); Tamura in Kubitzki (1998a). Our “liliaceous” genera (members of orders placed in the Lilianae) are therefore divided as shown below, largely following Kubitzki (1998a) and some more recent molecular analyses. ALISMATALES TOFIELDIACEAE: Pleea, Tofieldia. LILIALES ALSTROEMERIACEAE: Alstroemeria COLCHICACEAE: Colchicum, Uvularia. LILIACEAE: Clintonia, Erythronium, Lilium, Medeola, Prosartes, Streptopus, Tricyrtis, Tulipa. MELANTHIACEAE: Amianthium, Anticlea, Chamaelirium, Helonias, Melanthium, Schoenocaulon, Stenanthium, Veratrum, Toxicoscordion, Trillium, Xerophyllum, Zigadenus. -
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. -

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. -
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. -
Pollination and Comparative Reproductive Success of Lady’S Slipper Orchids Cypripedium Candidum , C
POLLINATION AND COMPARATIVE REPRODUCTIVE SUCCESS OF LADY’S SLIPPER ORCHIDS CYPRIPEDIUM CANDIDUM , C. PARVIFLORUM , AND THEIR HYBRIDS IN SOUTHERN MANITOBA by Melissa Anne Pearn A thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfillment of the requirements of the degree of MASTER OF SCIENCE Department of Biological Sciences University of Manitoba Winnipeg Copyright 2012 by Melissa Pearn ABSTRACT I investigated how orchid biology, floral morphology, and diversity of surrounding floral and pollinator communities affected reproductive success and hybridization of Cypripedium candidum and C. parviflorum . Floral dimensions, including pollinator exit routes were smallest in C. candidum , largest in C. parviflorum , with hybrids intermediate and overlapping with both. This pattern was mirrored in the number of insect visitors, fruit set, and seed set. Exit route size seemed to restrict potential pollinators to a subset of visiting insects, which is consistent with reports from other rewardless orchids. Overlap among orchid taxa in morphology, pollinators, flowering phenology, and spatial distribution, may affect the frequency and direction of pollen transfer and hybridization. The composition and abundance of co-flowering rewarding plants seems to be important for maintaining pollinators in orchid populations. Comparisons with orchid fruit set indicated that individual co-flowering species may be facilitators or competitors for pollinator attention, affecting orchid reproductive success. ii ACKNOWLEDGMENTS Throughout my master’s research, I benefited from the help and support of many great people. I am especially grateful to my co-advisors Anne Worley and Bruce Ford, without whom this thesis would not have come to fruition. Their expertise, guidance, support, encouragement, and faith in me were invaluable in helping me reach my goals. -
Ladys' Slipper Orchids of India
Ladys’ SlipperH.J. Chowdhery Orchids of India ABOUT THE BOOK The Lady's Slipper or Slipper Orchids are an extremely well known group of orchids. The are popularly called Lady's slippers because of the presence of a highly modified pouch-like lip or labellum, which looks similar to a lady's slipper. They are highly priced and much sought after in the floriculture industry as potted plants as well as cut flowers due to their enchantingly attractive, colourfull blooms and ability to remain fresh for several weeks. The presently known five lady's slipper orchid genera , which belong to the orchid subfamily Cypripedioideae are widely distributed in the temperate regions of Eurasia and North America, Central America south to Brazil and Bolivia, tropical Asia from India across to Taiwan, south-east Asia from Indo-China acrossP. druryi to the, which Philippines, is endemic New to Guinea, Western and Ghats. the Solomon Islands. In India, only two genera namely Cypripedium and Paphiopedilum are found, which are confined to the Himalayan and North-East Indian region except one species of Paphiopedilum The book is the first ever comprehensive taxonomic treatment of Indian Slipper orchids. In the introductory part of the book, a brief history of lady’s slipper orchids, their taxonomy and a glimpse of all the five known genera of this group has been provided. The main part of the text comprises of the detailed taxonomic information on the 14 species of lady’s slippers (Cypripedium-5 and Paphiopedilum-9) reported from India. The descriptions for all the species have been drawn from the live plants along with colour plates made from fresh flowers for the first time for these orchids. -
