Natural Range

Chromosome analyses using cold-induced banding patterns were carried out on 25 wild populations of Trillium grandiflorum (Michx.) L. throughout the natural range of the species. Banding patterns were fairly uniform within and between populations with the exception of those occurring in chromosome D which varied from three to five times more than the other chromosomes. This is different from the situation in the western North American species T. ovatum Pursh. in which chromosome C is the most variable and the Japanese species T. kamtschaticum Pall. in which chromosome A is the most variable. There was greater homogeneity of karyotypes in northern populations than in southern ones. Supernumerary chromosomes were found in four of the 25 populations. In one plant the karyotype had been altered by a spontaneous translocation which has produced two new chromosome variants.

Phylogenetic Implications

HPLC analysis of the true huckleberry species Gaylussacia baccata, G. dumosa, G. frondosa, G. mosieri, and G. ursina identified the 3-monoarabinosides, 3-monogalactosides, and 3-monoglucosides of cyanidin, delphinidin, malvidin, peonidin, and petunidin. Gaylussacia brachycera contained all anthocyanins, except peonidin-3-arabinoside. Gaylussacia brachycera differed from other species in percent delphinidin-3-arabinoside. It was higher than the other species in percent of the aglycone delphinidin and lower in cyanidin, and also higher in percent of the sugar arabinose. There were no detectable differences among the other species for anthocyanins, aglycones, or aglycone-sugars. The phylogenetic implications of the similarities among species of Gaylussacia and Vaccinium in anthocyanins, aglycones, and aglycone-sugars of the fruit were discussed.Key words: High-performance liquid chromatography, huckleberries, blueberries, chemotaxonomy, taxonomy, biosystematics

The purpose of this paper is to present what is known at the present time concerning the life histories and habits of the Mesoveliidae, particularly those of three species of the genus Mesovelia Muls. found in North America. Studies on our most common species, Mesovelia mulsanti bisignata Uhler, were carried out in Michigan and Kansas, while biological notes on the other two species were taken in the region of Douglas Lake, Michigan, their only known habitat. Isolated rearings and life history studies of all three species were made at Lawrence, Kansas.

Restricted Sense

About the time that Lord Walsingham's valuable paper on Acrolophus and Anaphora appeared (Trans. Ent, Soc., Lond., 1887, 137–173), Mr. Beutenmüller was working on the same group; but neither author has since attempted to recognize the species named by the other, so far as I am aware. In Prof. Smith's List Lep. Bor. Amer., 1891, the group is recognized as a family—Anaphoridæ—but this can hardly stand. The genera will fall in the Tineidæ, in the more restricted sense (see Walsingham, Proc. Zool. Soc., London, 1897, 139–175).

Forty selections, including 37 cultivars of Hamamelis spp., were evaluated for genetic similarities using randomly amplified polymorphic DNA (RAPD) markers. Cluster analysis identified seven groups, which included three groups of H. ×intermedia cultivars, two groups of H. vernalis, and one group each of H. mollis and H. japonica. Three H. ×intermedia cultivars, `Arnold Promise', `Westerstede', and `Carmine Red', did not group closely with the other 20 cultivars of H. ×intermedia. Selections of the North American species H. vernalis were quite distinct from the Asiatic selections. However, data are presented that suggest hybridization exist between Asiatic Hamamelis spp. and H. vernalis. Genetic similarities between known half-sib families provides evidence that the cultivar pairs `Arnold Promise'—`Winter Beauty' and `Carmine Red'—`Hiltingbury' are, themselves, not likely half-sibs.

Seaside Alder

Alnus maritima [Marsh.] Nutt. (seaside alder) is a rare, North American species with strong potential for use in managed landscapes. Information on the propagation and production of this species is not available. Our objective was to evaluate the potential for using softwood cuttings to propagate A. maritima, with emphasis on how IBA and plant provenance affect rooting success. Propagation trials were conducted with cuttings from seven trees native to the Delmarva Peninsula and seven trees from Oklahoma. Cuttings from both provenances were collected on 14 June and 23 Aug. Cuttings were wounded; treated with 0, 1, or 8 g/kg IBA; and placed under intermittent mist in a greenhouse for 9 weeks. The highest percentage of rooting (67.9) was achieved for the Oklahoma provenance by using 8 g/kg IBA in June. Across IBA treatments, rooting of cuttings from Oklahoma, 54.8% (June) and 12.4% (August), was higher than rooting of cuttings from Delmarva, 27.1% (June) and 3.1% (August). IBA at 8 g/kg caused a higher rooting percentage than the other IBA rates at both times of the season. More cuttings collected 14 June rooted (41%) than those collected 23 Aug. (7.7%) over IBA treatments. Another experiment involved cuttings from one juvenile, greenhouse-grown seedling from Oklahoma that showed 100% rooting with both 1 and 8 g/kg IBA. Shoot growth appeared more vigorous on rooted cuttings from these juvenile stems than on plants derived by rooting mature tissue collected in nature. We conclude that using softwood cuttings can be an effective way to multiply clones of A. maritima, particularly when stock plants are juvenile and cuttings are treated with IBA.

AbstractThe Nearctic species of the subgenus Anomophagus Reitter of the genus Rhizophagus Herbst are revised. Four taxa are recognized: R. brunneus brunneus Horn 1879, R. brunneus fenyesi Méquignon 1913a, R. pseudobrunneus sp.nov., and R. galbus sp.nov.For the other Nearctic species of the genus, a diagnosis, a type material section, and distributional notes are provided. Two new taxa are described, R. minutus rotundicollis and R. pusillus. Seven specific names are treated as new junior synonyms, namely (with the valid name in parentheses): R. longiceps Casey 1916 and R. rectus Casey 1916 (= R. cylindricus LeConte 1866); R. minutus quadriguttatus Méquignon 1913b (= R. minutus minutus Mmnerheim 1853); R. remotus luteus Méquignon 1913b (= R. remotus LeConte 1866); R. sculpturatus horni Méquignon 1913b (= R. sculpturatus Mannerheim 1852); R. dimidiatus testaceus Méquignon 1913b and R. dimidiatus assimilis Méquignon 1913b (= R. dimidiatus Mannerheim 1843). The subgenera name Syringobidia Casey 1916 (type species: R. cylindricus LeConte 1866) is treated as a new junior subjective synonym of Rhizophagus s.str. A key to all Nearctic species of Rhizophagus is provided with distribution maps of the species.

AbstractGroup VI of North American Ips contains I. perturbatus (Eichhoff), I. hunteri Swaine, I. utahensis Wood and I. woodi Thatcher. A key and descriptions of species are given. Members of this group have the third declivital spine capitate with the tip conical and acute. The front of the head is evenly convex except in females of I. utahensis which have the lower part of the frons faintly elevated. I. woodi breeds in pine while the other three species breed in spruce.

First Time

Nixe dorothae n. sp. (Ephemeroptera: Heptageniidae) is described from southern Indiana, USA based on larvae, males, and females. Larvae are easily differentiated from those of the other known North American species by the presence of two rows of denticles on the tarsal claws. Males are differentiated from congeners by the presence of median spines on the apical sclerites of the penes and reddish-brown abdominal terga. The larva of N. rusticalis is described for the first time; it is differentiated from known North American Nixe by having more than 15 comb setae on the maxilla. A preliminary key for the larvae of the known North American Nixe is provided.
