Dykes on Irises DYKES ON IRISES A Reprint of the contributions of the late W. R. Dykes, L-es-L., to various journals and periodicals during the last 20 years of his life FOREWORD TO THIS EDITION In the 1920s George Dillistone diligently compiled articles written by William Rickatson Dykes during the last 20 years of his life and these were published by the then Iris Society, later to become the British Iris Society. These articles are now out of copyright and are reprinted here for all to freely enjoy. Some of the names and thoughts are now dated, but surprisingly much of the detail still makes very interesting reading and the enthusiasm has not diminished despite the gulf of a large number of years. I personally have found it very rewarding to have read the articles whilst transferring them to a modern medium. Some of the syntax is now outdated, but has been left due to time pressure and it does not detract from the content. The names of some species have been changed over the years and the reader needs to be wary of this, e.g. I. orientalis is now I. sanguinea, but anyone with more than a passing acquaintance with irises is unlikely to be baffled for long. I hope you enjoy reading the articles, Alun Whitehead Contents Page 1 Foreword to this part edition ...............................................................2 2 Contents ................................................................................................3 3 Irises......................................................................................................6 4 Irises for Amateurs ............................................................................. 17 5 Some Early-Flowering Bulbous Irises................................................23 6 Early Flowering Bulbous Irises ..........................................................25 7 Some Early Flowering Irises...............................................................30 8 Early Bearded Irises............................................................................34 9 August Irises.......................................................................................39 10 Autumn-Flowering Irises ................................................................... 41 11 Irises from October to August ............................................................44 12 An Iris Garden in Winter....................................................................45 13 Some Garden Irises.............................................................................49 14 Garden Irises.......................................................................................59 15 A Dalmatian Iris Hunt ........................................................................67 16 An Iris Excursion ................................................................................76 17 The Origin of Some Garden Irises..................................................... 80 18 Hybridisation in the Iris .....................................................................84 19 Curious Results of Hybridisation ....................................................... 91 20 Self-Fertilisation in Irises ...................................................................92 21 Irises from Seed ..................................................................................93 22 On Raising Irises from Seed ...............................................................95 23 Notes on Various Species and Hybrids 1.

    MIDWEST REGIONAL HOSTA SOCIETY NEWSLETTER HOSTA LEAVES ISSUE NUMBER 70 SPRING 2011 WINTER SCIENTIFIC MEETING MADISON, WISCONSIN CONVENTION President Vice-President Secretary Treasurer Editor Lou Horton Mary Ann Metz Glenn Herold Barb Schroeder Floyd Rogers 1N735 Ingalton 1108 W. William St. 1004 W. Northcrest Ave 1819 Coventry Dr 22W213 Glen Valley Dr West Chicago, IL 60190 Champaign, IL 61821 Peoria, IL 61614 Champaign, IL 61822 Glen Ellyn, IL 60137 President‟s Message A very successful Winter Scientific Meeting is behind us now as (I devoutly hope) is a pretty tough winter. The WSM was moved to a new venue at the Wyndham hotel in Lisle, IL this year and from all reports, the change worked for all involved. We had excellent attendance and the speakers all came through with excellent presentations. For those MRHS members who could not attend, all is not lost as we have presentation summaries in this issue of Hosta Leaves. The 2012 edition of the Winter Scientific is set for Saturday, January 21st. The folks in the Wisconsin hosta societies are working hard on putting together a wonderful convention schedule for the weekend of July 7-9th in Madison, Wis. The Madison area is not only beautiful to visit but it is home to some enthusiastic hostaphiles with truly fantastic gar- dens. This convention is within easy driving distance for many of our members who have never treated themselves to a convention. Why not this year? I have a major concern about the lack of response to the need for a local society to host the 2013 and 2014 MRHS conventions.

Jean Witt noted that the Siberian parent was a yellow 40 chromosome Siberian seedling, closer in form and color to I. forrestii than to I. wilsonii. The SIGNA Checklist states that the Siberian parent was I. wilsonii. Jean reviewed her notes, and said this is incorrect, it was a forrestii seedling.

  • Iris Sibirica and Others Iris Albicans Known As Cemetery
    Iris Sibirica and others Iris Albicans Known as Cemetery Iris as is planted on Muslim cemeteries. Two different species use this name; the commoner is just a white form of Iris germanica, widespread in the Mediterranean. This is widely available in the horticultural trade under the name of albicans, but it is not true to name. True Iris albicans which we are offering here occurs only in Arabia and Yemen. It is some 60cm tall, with greyish leaves and one to three, strongly and sweetly scented, 9cm flowers. The petals are pure, bone- white. The bracts are pale green. (The commoner interloper is found across the Mediterranean basin and is not entitled to the name, which continues in use however. The wrongly named albicans, has brown, papery bracts, and off-white flowers). Our stock was first found near Sana’a, Yemen and is thriving here, outside, in a sunny, raised bed. Iris Sibirica and others Iris chrysographes Black Form Clumps of narrow, iris-like foliage. Tall sprays of darkest violet to almost black velvety flowers, Jun-Sept. Ht 40cm. Moist, well drained soil. Part shade. Deepest Purple which is virtually indistinguishable from black. Moist soil. Ht. 50cm Iris chrysographes Dykes (William Rickatson Dykes, 1911, China); Section Limniris, Series Sibericae; 14-18" (35-45 cm), B7D; Flowers dark reddish violet with gold streaks in the signal area giving it its name (golden writing); Collected by E.

    Bothalia 41,1: 1–40 (2011) Systematics and biology of the African genus Ferraria (Iridaceae: Irideae) P . GOLDBLATT* and J .C . MANNING** Keywords: Ferraria Burm . ex Mill ., floral biology, Iridaceae, new species, taxonomy, tropical Africa, winter rainfall southern Africa ABSTRACT Following field and herbarium investigation of the subequatorial African and mainly western southern African Ferraria Burm . ex Mill . (Iridaceae: Iridoideae), a genus of cormous geophytes, we recognize 18 species, eight more than were included in the 1979 account of the genus by M .P . de Vos . One of these, F. ovata, based on Moraea ovata Thunb . (1800), was only discovered to be a species of Ferraria in 2001, and three more are the result of our different view of De Vos’s taxonomy . In tropical Africa, F. glutinosa is recircumscribed to include only mid- to late summer-flowering plants, usually with a single basal leaf and with purple to brown flowers often marked with yellow . A second summer-flowering species,F. candelabrum, includes taller plants with several basal leaves . Spring and early summer-flowering plants lacking foliage leaves and with yellow flowers from central Africa are referred toF. spithamea or F. welwitschii respectively . The remaining species are restricted to western southern Africa, an area of winter rainfall and summer drought . We rec- ognize three new species: F. flavaand F. ornata from the sandveld of coastal Namaqualand, and F. parva, which has among the smallest flowers in the genus and is restricted to the Western Cape coastal plain between Ganzekraal and Langrietvlei near Hopefield . Ferraria ornata blooms in May and June in response to the first rains of the season .
