Chromosome number determinations were made from 407 wild or transplanted individuals and seedlings representing 65 taxa and hybrids inEuthamia andSolidago. The following are first reports:Euthamia remota, 2n=9II;Solidago leavenworthii, 2n=54;S. mollis, 2n=36;S. mollis var.angustata, 2n=36;S. rigida var.glabrata, 2n=9II;S. sempervirens var.azorica, 2n=9II; andS. sparsiflora, 2n=54. Most species have been sampled only a few times or are consistently of one cytotype. Sufficient counts have been… 

Cytogeography of the Solidago rugosa Mill. Complex (Asteraceae: Astereae) in Eastern North America

The diversity in ploidy levels was independent of the size of the range and the diversity of growing conditions among the three species of S. rugosa in much of eastern North America.

CHROMOSOME NUMBER DETERMINATIONS IN FAM. COMPOSITAE, TRIBE ASTEREAE. VII. MOSTLY EASTERN

Chromosome numbers are reported for the first time for 303 individuals of 112 taxa and cultivars and five hybrids from 16 genera, nearly all from eastern Canada and the eastern United States. Counts

Morphological and cytological diversity of goldenrods (Solidago L. and Euthamia Nutt.) from south-western Poland

The results of the study showed that life traits of invasive Solidago and Euthamia taxa were clearly not connected with the effectiveness of invasion, and the spread of particular taxa was also notconnected with the ploidy level and DNA content.

A new species of Triplinerviae goldenrod in eastern Canada (Asteraceae: Astereae): Solidago brendiae

A new species of Solidago is described from collections made in Maritime Canada and Fernald was correct in recognizing two closely related races native to the Canadian Maritime s that are similar to the mostly western S. lepida, but they are treated here as varieties of S. fallax.

Chromosome Number Determinations in Solidago (Asteraceae: Astereae)

abstract Chromosome numbers are reported for 133 individuals of 41 taxa and cultivars and four hybrids in the goldenrod genus Solidago from Canada, the United States and botanical gardens in Europe.

Chromosome numbers in hybrids between invasive and native Solidago (Asteraceae) species in Europe

This study evidenced a triploid of S. ×snarskisii from one locality in Lithuania, as well as confirmed diploids in the progenies ofS.

Cytogeography of Solidago subsect. Glomeruliflorae (Asteraceae: Astereae)

Chromosome numbers were determined for 347 individuals of Solidago subsect, including 151 new reports, for the following taxa: Solidago caesia L. caesia, S. curtisii var.

Solidago Vossii (Asteraceae), a New Species of Goldenrod from Northern Michigan

Morphologically, S. vossii is most similar to S. houghtonii, but differs in several features, and the morphological features of the two species are compared and their phylogenetic relationship discussed.

Cytogeography of Solidago sect. Erectae, sect. Villosicarpae, sect. Squarrosae, and sect. Brintonia (Asteraceae: Astereae)

Chromosome numbers are reported for 67 individuals of 13 species of Solidago sect. Erectae, S. sect. Squarrosae, and S. sect. Villosicarpae from 65 locations in eastern Canada and the eastern United

Morphological, Molecular, and Biogeographic Evidence for Specific Recognition of Euthamia hirtipes and Euthamia scabra (Asteraceae, Astereae)

Abstract The number and identity of species within Euthamia (Asteraceae, Astereae) have varied considerably among taxonomic treatments. Euthamia graminifolia (L.) Nutt. is often treated broadly,

A biosystematic study of the Solidago canadensis (Compositae) complex. I. The Ontario populations

Populations from 138 locations in Ontario were sampled and found to contain three levels of polyploidy: diploid, tetraploids, andhexaploid; four species are separated by major genetic barriers and attempts to cross them have not been successful except in the case of S. lepida where a single hybrid plant has been raised.

Supernumerary Chromosomes of some Species of Solidago and a Related Taxon

A study of the distribution, frequency, and behaviour of the supernumerary chromosomes found in populations of 12 species of the genus Solidago and one closely related taxon, Euthamia graminifolia, all of the family Compositae, tribe Asterieae.

STUDIES ON SOLIDAGO L.: IV. THE CHROMOSOME NUMBERS OF CERTAIN TAXA OF THE GENUS SOLIDAGO

The authors report the chromosome numbers of 25 taxa of the genus Solidago which had not yet been studied from this standpoint, and review the literature to conclude that most of the species have differentiated gradually.

Chromosome numbers of goldenrods, Euthamia and Solidago (Compositae-Astereae)

Chromosome number determinations were made from 227 populations of 43 taxa of Euthamia and Solidago. Nearly all were confirmations of previous reports. The majority of the populations sampled were

CHROMOSOME STUDIES IN WESTERN NORTH AMERICAN COMPOSITAE

Observations on meiotic behavior and, for plants in which meiosis was found to be irregular, an indication of pollen viability are indicated and it is hoped that this paper constitutes a worthwhile addition to the authors' growing understanding of evolutionary patterns in the Compositae.

Further Observations on the Chromosome Morphology of Some Solidago Species

It is concluded that chromosome morphological data is likely to be of greater value in clarifying the taxonomic status of the higher categories of the family Asteraceae than in differentiating related diploid or polyploid species.
