The Genus Arabis in Iowa

During the past year a critical study was made of the genus Arabis in Iowa. The specimens of the herbaria of Iowa State College at Ames. State University of Iowa at Iowa City, and Grinnell College at Grinnell were examined. Hopkins\u27 recent paper Arabis in Eastern and Central North America was used in the identification of the plants. No attempt has been made to monograph the Iowa Arabis previously. The only records are those that have been published in the various papers on the state flora, only a few of which are at all complete for the state as a whole. Green (2) listed 7 species, Cratty (1), 7 species, and Hopkins (3) cited 6 species and 2 varieties from Iowa. The present investigation found 8 species and 3 varieties. According to Hopkins (3) two of the Iowa species undergo nomenclatural changes. A. pycnocarpa Hopkins was described to include the plant formerly known as A. hirsuta (L.) Scop. and A. brachycarpa (T. & G.) Britton listed by Cratty and Greene is known now as A. divaricarpa Nelson. In the following pages a key to the Iowa species is given as is also a brief description of them, and the citations of specimens examined. Specimens from the University of Iowa are indicated with a (U), those from Grinnell with a (G). All the others are in the herbarium of Iowa State College

Funaria Flavicans Michx. In Iowa

On May 18, 1935, the writer collected some mosses in the vicinity of the U. S. Fish Hatchery, southeast of Manchester, Iowa. When the late Miss Lucy M. Cavanagh identified these, she found that there was a collection of Funaria ftavicans Michx., which heretofore has not been reported from this state. Miss Cavanagh had planned to report this moss at last year\u27s meeting but her illness prevented it. This particular species was found growing on the ground in a cleared sheep pasture east of the Fish Hatchery. Part of this collection is in the Herbarium of the State University of Iowa

The Rose Crimson Rambler and Its Progenies

The year 1893 is an important landmark to the rosarian as in that year Charles Turner of Slough, England, introduced the Crimson Rambler rose to the occidental world. Nothing is known of its parentage, it having been introduced from Japan where it had been grown for an unknown period of time. When it was first introduced it was called the Engineer. Later, it was known as Turner\u27s Crimson Rambler. Still later the name Turner was dropped, making it the Crimson Rambler as we know it today. Without regard to name, this rose introduction has proven to be a prolific parent in the production of new varieties. Although the variety belongs to the multiflora group, and many of the descendants are found under that designation, yet its influence also is evident in Polyantha, Lambertiana, Hybrid Wichuraiana, Hybrid Polyantha, and other groups

Soleil D\u27or, The Progenitor of Golden Colored Roses

In 1900 when Monsieur J. Pernet-Ducher introduced a new yellow rose, a seedling of Persian Yellow pollinated by Antoine Ducher, and named it Soleil d\u27Or, he little realized the magical color combinations that this one variety was destined to transmit to the succeeding generations of hybrid tea roses. From the introduction of La France in 1867 until 1900, there were no true yellow hybrid teas. During this period the Noisette Marechal Niel fulfilled the need for a yellow rose. Needless to say, Soleil d\u27Or soon became very popular both as a garden subject and as a source of new blood in hybridization. The popularity of this one rose in breeding work is attested by the fact that the Pernetiana class was erected to include this group, but as the number of hybrids increased, the line of demarcation between hybrid teas and pernetianas disappeared until there is now a tendency to designate all of them hybrid teas

MME. Caroline Testout: The Grand Dame of the Roses

In all breeding work one finds that certain individuals are outstanding in the production of superior progeny. In animal breeding these individuals form the basis for pedigreed stock. An intensive study on the parentage of rose varieties has revealed that certain roses also have produced more named offspring than others. To obtain this information, it was necessary to make a search through the world\u27s most important literature on the rose. This study resulted in the compilation of an index of about 5,000 rose varieties on which parentage data had been recorded

Rosa Multiflora and Its Progeny

The introduction of Rosa multiflora Thunberg into England from Japan in 1781 was a high light in the history of rose growing. This one species has proven very valuable in the production of new varieties. Its offspring have been classed with several different groups depending on their habit of growth and flowering. Rosa multiflora progeny are found among the Multiflora, Polyantha, Hybrid Musk, Lambertiana, Hybrid Wichuraiana, Hybrid Polyantha, and other groups

The Progeny of La France, the First Hybrid Tea

Just what prompted Guillot fils of Lyon-Montplaisir, France, to name a pink· rose, introduced in 1867, La France may never be known. Subsequent history has shown that this rose was the first Hybrid Tea. It was grown from a seed of Mme. Bravy, a creamy white tea, fertilized by Victor Verdier a bright rose-colored Hybrid Perpetual. Since the French rosarians have originated the first variety that became the progenitor of most of the major classes of modern roses, no better name could have been found for the first Hybrid Tea. Around the turn of the twentieth century, this class of roses became the most popular of the modern roses, and its popularity has not diminished in the ensuing years

The Prolific General Jack Rose

The year 1853 stands as a milestone in the progress of rose development, for in that year Roussel of France introduced General Jacqueminot to the world. Although it was introduced over 88 years ago, it is still one of the most popular roses of its class. The ordinary course of any one variety is generally far less than this. The Hybrid Perpetual group of roses, to which General Jack belongs, dates from the turn of the nineteenth century. Two of the most important progenitors of the group were introduced about 1830. The year 1837 is usually given as the year of introduction of the first true Hybrid Perpetual. Considering this date, one realizes that Roussel\u27s variety was one of the first of its class

Moving conferences online: lessons learned from an international virtual meeting

We consider the opportunities and challenges associated with organizing a conference online, using a case study of a medium-sized (approx. 400 participants) international conference held virtually in August 2020. In addition, we present quantifiable evidence of the participants’ experience using the results from an online post-conference questionnaire. Although the virtual meeting was not able to replicate the in-person experience in some aspects (e.g. less engagement between participants) the overwhelming majority of respondents found the meeting an enjoyable experience and would join similar events again. Notably, there was a strong desire for future inperson meetings to have at least some online component. Online attendance by lower-income researchers was higher compared with a past, similarthemed in-person meeting held in a high-income nation, but comparable to one held in an upper-middle-income nation. This indicates that online conferences are not a panacea for diversity and inclusivity, and that holding in-person meetings in developing economies can be at least as effective. Given that it is now relatively easy to stream contents of meetings online using low-cost methods, there are clear benefits in making all presented content accessible online, as well as organizing online networking events for those unable to attend in person
