The in- spiration to move ahead, however, came from a detour. During the stud- ies of another plant in my collection, I stumbled upon some very interest- ing information. According to the late Günther Ludwig, his well-known fel- low orchid explorer Eberhard Wald- vogel brought back a strange Odon- toglossum to Germany from his Co- lombian trip in 1970 (along with plants of the rare Odontoglossum naevi- um Lindl.). The unidentifi ed strange plant was recently described by Jürgen Röth (2009) as Odontoglossum x lud- wigianum Roeth. The author suggests Odontoglossum nobile and Odonto- glossum blandum Rchb.f. as parents for this alleged natural hybrid. To add a new name for this particular natural hybrid is superfl uous, however, since it already has been described as Od- ontoglossum x pauwelsii Rolfe (1909), and the man-made

  • Development of the Embryo and the Young Seedling Stages of Orchids
    Development of the Embryo II' L_ and the Young Seedling Stages of Orchids YVONNE VEYRET Until 1804, when Salisbury found that orchid seeds could germinate, the seeds were considered sterile. Much later, in 1889, Bernard's discovery of the special conditions necessary for their growth and development ex- plained the lack of success in previous attempts to obtain plantules, and the success, although mediocre, when sowing of seed took place at the foot of the mother plant. Knowing the rudimentary state of minute or- chid embryos, one can better understand that an exterior agent, usually a Rhizoctonia, can be useful in helping them through their first stages of development (Bernard, 1904). Orchid embryos, despite their rudimentary condition, present diverse pattems of development, the most apparent of which are concerned with the character of the suspensor; there are other basic patterns that are re- vealed in the course of the formation of the embryonic body. These char- acteristics have been used differently in the classification of orchid em- bryos. This will be discussed in the first part of this chapter, to which will be added our knowledge of other phenomena concerning the embryo, in particular polyembryonic and apomictic seed formation. The second part of this chapter is devoted to the development of the young embryo, a study necessary for understanding the evolution of the different zones of the embryonic mass. We will also examine the characteristics of the em- bryo whose morphology, biology, and development are specialized when compared to other plants. 3 /-y , I', 1 dT 1- , ,)i L 223 - * * C" :.

  • November 2008 Newsletter
    Odontoglossum Alliance Newsletter Volume 5 November 2008 Odontoglossum Species Reference Edition Special Edition Odontoglossum Species This is a Special Edition of the Odontoglossum Alliance Newsletter devoted to producing a reference edition of the odontoglossum species. Dr. Guido Deburghgraeve has an extensive collection of odontoglossum species and provided us with a DVD of the flowers of the species in his collection. This edition is devoted to showing these flowers. The pic­ tures are augmented by (1) additional pictures of species from Steve Beckendorf’s collection and (2) the complete list of odontoglossum species as produced by Kew Gardens. This list contains what they consider as the recognized names as well as the historical names applied to each species. It is planned that this edition will be repeated in the future with other genera in the Odontoglossum Alliance. The pictures have (when available) both a facing photograph and a profile photograph. Where there are multiple photographs of the same species, this is done to show the variability within the species. There were more photographs available then we had space and money to show in this edition. A number of these species are marked with an X indicat- ing a natural hybrid. Please see the explanation and definition of natural hybrids by Steve Beckendorf in the newsletter following the photographs. The Alliance is indebted to Dr. Guido Deburghgraeve for supplying the DVD of his flowers, to Stig Dalstrom for consulting on the material and to Dr. Steve Beckendorf for his consultation, flower pictures and explanation of the mate­ rial contained m this issue.

Actually I have been flat out worlang and there is not enough time in the day. , j • t A trip to Auddand to talee my daughter bade to Uni allowed me to drop m on Jane Frear and also Alf Day recently. Now those two are enough to generate some entoiasm in any orchid grower. Jane is in her 80’s, in indifferent health, her plants in beautiful order and her small greenhouse almost bursting at the seams. Where aU the pampered seed^gs in the house and garage and the rows of flaslcs are going to he housed, I don’t Icnow.

Species on monocots ARTICLE (Acoraceae to Xyridaceae, excluding Poaceae) Uwe Braun1, Pedro W. Crous2, and Chiharu Nakashima3 1Martin-Luther-Universität, Institut für Biologie, Bereich Geobotanik und Botanischer Garten, Herbarium, Neuwerk 21, 06099 Halle (Saale), Germany; corresponding author e-mail: [email protected] 2CBS-KNAW, Fungal Biodiversity Centre, Uppsalalaan 8, 3584 CT Utrecht, The Netherlands 3Graduate School of Bioresources, Mie University, 1577 Kurima-machiya, Tsu, Mie 514-8507, Japan Abstract: Cercosporoid fungi (formerly Cercospora s. lat.) represent one of the largest groups of Key words: hyphomycetes belonging to the Mycosphaerellaceae (Ascomycota). They include asexual morphs, Ascomycota asexual holomorphs, or species with mycosphaerella-like sexual morphs. Most of them are leaf-spotting Cercospora s. lat. plant pathogens with special phytopathological relevance. In the first part of a new monographic work, Liliopsida cercosporoid hyphomycetes occurring on other fungi (fungicolous species), on ferns (pteridophytes) and hyphomycetes gymnosperms were treated. This second part deals with cercosporoid fungi on monocots (Liliopsida; Equisetopsida, Magnoliidae, Lilianae), which covers species occurring on host plants belonging to families arranged in alphabetical order from Acoraceae to Xyridaceae, excluding Poaceae (cereals and grasses) which requires a separate treatment. The species are described and illustrated in alphabetical order under the particular cercosporoid genera, supplemented by keys to the species concerned. A detailed introduction, a survey of currently recognised cercosporoid genera, a key to the genera concerned, and a discussion of taxonomically relevant characters were published in the first part of this series.Neopseudocercospora , an additional recently introduced cercosporoid genus, is briefly discussed.
