Biological Differences

While investigating the biology of the North American species of Hypomolyx, field workers in Manitoba found a vestigial, or short-winged, and a long-winged form under apparently identical conditions in about equal numbers. Although biological differences were nor then apparent, there was doubt as to whether they were dealing with one dimorphic species or with two distinct species, A search for morphological characters brought to light numerous differences between the two forms, supporting the view that two species were present. These differences, a description the previously unrecognized species, and notes concerning the status of the genera Hylobius and Hypomolyx are reported below.

Cirsium Undulatum

The morphology and specific differences of Cirsium undulatum (Nutt.) Spreng. and of C. flodmanii (Rydb.) Arthur are described and their Canadian distributions are reported in detail. The chromosome numbers are C. undulatum f. undulatum and f. album Farwell, 2n = 26; C. flodmanii f. flodmanii and f. albiflorum D. Löve, 2n = 22. The origin of four North American species of Cirsium that do not follow the world-wide base number 17 is discussed; it is postulated that reduction in number has occurred by translocations. The chromosomes of species with reduced numbers are larger than those of the unreduced species but the total length of the chromosomes of both groups is approximately the same.

AbstractThe species of the genus Entomacis Foerster in North America north of Mexico are revised. Nineteen species (12 new), including 8 species of the Holarctic-wide perplexa species group, are keyed, described, and figured. These taxa are E. ambigua (Brues), E. apopkaensissp. nov., E. arcticasp. nov., E. cellariasp. nov., E. cepasp. nov., E. eorariasp. nov., E. floridana (Ashmead), E. grandiclavasp. nov., E. longii (Ashmead), E. mellipetiola (Ashmead), E. parambiguasp. nov., and perplexa group members E. californica (Ashmead), E. microbipunctatasp. nov., E. notioxerasp. nov., E. oulasp. nov., E. parvasp. nov., E. perplexa (Haliday), E. sapratasp. nov., and E. subemarginata (Ashmead). Hemilexodes canadensis (Harrington) is synonymized under Entomacis mellipetiola (Ashmead) (syn. nov.). The status of Entomacis latipennis (Ashmead), E. filiformis (Ashmead), and Hemilexis jessei Mann is reviewed. New character complexes, particularly chaetotaxy, are emphasized for Diapriidae species taxonomy.

Abstract>The status of the genus Plega is discussed and a preliminary survey of the North American species is presented. Plega yucatanae, a new species reared from the cells of Megachile exaltata Smith, is described and compared with its near relatives. The immature stages are described and biological information is given.

Chromosome numbers are given for a number of North American species in the genera Draba, Erophila, and Erysimum. New basic chromosome numbers are suggested for North American species of Draba and Erysimum and it is suggested that Erysimum inconspicuum reproduces by agamospermy.

scholarly journals Corrections to Phytologia,vol. 102 (3) – Rumicastrum dielsii (Poelln.) Carolin is an “alien,” R. cylindricum (Poelln.) Carolin is Elatinaceae, R. monogynum (Poelln.) Carolin is incertae sedis, and the combination in Rumicastrum for Talinum nanum Nees was neglected

The Status

In Phytologia 102 (4): 116–123, Hershkovitz recombined into Rumicastrum Ulbrich 65 Australian Montiaceae species originally classified in Calandrinia Kunth. Three of these species, all described by Karl von Poellnitz, do not pertain to Rumicastrum. The type specimen of Rumicastrum dielsii (Poelln.) Carolin is Calandrinia menziesii (Hook.) Torr. & A.Gray, a western North American species naturalized in Australia. The type specimen of Rumicastrum cylindricum (Poelln.) Carolin appears to be Bergia L. (Elatinaceae), but the species is not determined here. The type specimen of Rumicastrum monogynum (Poelln.) Carolin has not been located and may have been destroyed. The protolog is incomplete, but the specified characteristics suggest that it does not pertain to Montiaceae. Its identity is not determined here. In addition to the above, Hershkovitz listed Calandrinia pusilla Lindl., nom illegit., as a nomenclatural rather than taxonomic synonym of Rumicastrum eremaeum (Ewart) Carolin. Although homotypic, it is a taxonomic synonym. The status of other possible taxonomic synonyms combined into Rumicastrum also is discussed. Finally, Hershkovitz ascribed authorship of several Rumicastrum combinations to Roger Carolin. The question as to whether authorship should be ascribed as “Carolin ex Hershk.” is here addressed.

The Status

The article presents the Smooth rose, Rosa blanda Ait. distribution in Poland based on literature data, available herbarium materials, and shared unpublished data. R. blanda is a North American species that is cultivated and has become wild throughout Poland, where it has the status of a domestic, non-invasive kenophyte. This species is rare in Poland. Only 22 sites have been identified (mainly in the central and northwestern part of the country), as created spontaneously or as remaining from old, local cultivations. However, it cannot be excluded that this species will become invasive in the future and will negatively affect native flora species, especially through its ability to cross with other rose species (including invasive R. rugosa Thunb.).

Holarctic Species

Sixteen North American species of the genus Saotis Förster, 1869 are reviewed. Most of them have Holarctic distribution. Four new species of this genus are described: S. erythropleura sp. nov., S. rufigaster sp. nov., S. tinctor sp. nov. and S. truncator sp. nov. The Nearctic subspecies of four Holarctic species are described and redescribed: S. brevispina lissor subsp. nov., S. granulator albator subsp. nov., S. renovata rufipes subsp. nov. and S. pygidiator nearctor Kasparyan, 2009. A key to the Nearctic species of Saotis is given. The status of the European Iskarus Kolarov, 1987 as a monotypic subgenus of the genus Saotis is justified due to peculiarities in structure of its ovipositor.
