Abstract. Genome size (C-values) and pollen viability staining were applied as new criteria to investigate the species of the genus Helleborus Linnaeus (Ranunculaceae). All species have the same chromosome number (2n=32). However, the nuclear DNA content, as measured by flow cytometry with propidium iodide, could be demonstrated to range between 19 pg to 35.7 pg. The different genome sizes of the species coincided to a large extent with earlier determined section boundaries based on morphology… Expand
Genome sizes for all genera of Cycadales.
TLDR
The narrow range in nuclear DNA content within a genus is remarkable for such an old group, and there does not seem to be a correlation between genome size and the number of chromosomes. Expand
The systematic value of nuclear DNA content in Galanthus
TLDR
Genome size was applied as a new criterion to investigate the relationships within the genus Galanthus L. (Amaryllidaceae) and DNA content confirmed the close relationships in some species pairs, including G. nivalis and tetraploids and hexaploids in G. elwesii. Expand
The systematic value of nuclear DNA content in Agave L. and some related genera of the Agavaceae
Summary: C-value was applied as a new criterion to investigate the relationships within the genus Agave L. (Agavaceae). Samples representing nearly 40 taxa were investigated, augmented with data fromExpand
Nuclear DNA amounts in Macaronesian angiosperms.
TLDR
The authors' data support the hypothesis that the insular selection pressures in Macaronesia favour small C-values and genome sizes and both positive and negative correlations between infrageneric nuclear DNA amount variation and environmental conditions on Tenerife were also found in several genera.

Analysis of the taxonomic subdivision within the genus Helleborus by nuclear DNA content and genome-wide DNA markers
TLDR
The first genetic analysis in the genus Helleborus, including the two newly described species H. liguricus and H. abruzzicus, based on multilocus amplified fragment length polymorphism (AFLP) markers with a genome-wide distribution in combination with nuclear DNA content data is presented. Expand
Genome Sizes in Hepatica Mill: (Ranunculaceae) Show a Loss of DNA, Not a Gain, in Polyploids
TLDR
Contrary to the increase in genome size suggested earlier for Hepatica, a significant (6%–14%) loss of nuclear DNA in the natural allopolyploids was found. Expand
Genome size analysis of selected species of Aloe (Aloaceae) reveals the most primitive species and results in some new combinations
TLDR
Genome size (C-value) is used as a new criterion to investigate the taxonomy of the genus Aloe and it is shown that A.Berger & Marloth have by far the lowest DNA content of all measured Aloe species and might belong to the same section. Expand
Genome size for the species of Nerine Herb. (Amaryllidaceae) and its evident correlation with growth cycle, leaf width and other morphological characters
TLDR
Nuclear DNA content (2C) is used as a new criterion to investigate nearly all species of the genus Nerine Herb and is shown to be relevant to throw new light on the relationships between Nerine species. Expand
The systematic value of nuclear genome size for “all” species of Tulipa L. (Liliaceae)
TLDR
Nuclear genome size, as measured by flow cytometry with propidium iodide, was used to investigate the relationships within the genus Tulipa L. (Liliaceae) and revealed a systematic association between T. Koch and the triploid T. orphanidea Boiss. Expand
Taxonomic implications of genome size for all species of the genus Gasteria Duval (Aloaceae)
TLDR
Nuclear DNA content as measured by flow cytometry is shown to be relevant to provide additional information on the relationships between Gasteria species and might be the most primitive member of the genus. Expand
