The number of known plants species in the world and its annual increase
Tập 261 Số 3 - Trang 201
We have counted the currently known, described and accepted number of plant
species as ca 374,000, of which approximately 308,312 are vascular plants, with
295,383 flowering plants (angiosperms; monocots: 74,273; eudicots: 210,008).
Global numbers of smaller plant groups are as follows: algae ca 44,000,
liverworts ca 9,000, hornworts ca 225, mosses 12,700, lycopods 1,290, ferns
10,560 and gymnospe...
Ophiocordyceps xuefengensis sp. nov. from larvae of Phassus nodus (Hepialidae) in Hunan Province, southern China
Tập 123 Số 1 - Trang 41
An entomogenous taxon, associated with larvae of Phassus nodus (Hepialidae)
collected from Xuefeng Mountains, Hunan Province, China, was found to be a new
species, Ophiocordyceps xuefengensis sp. nov. It differs from similar species in
having long stromata, without a sterile apex, narrow asci, long ascospores and
by its occurrence on Phassus nodus in living root or trunk of Clerodendrum
cyrtophyll...
Stephanocha nom. nov., a replacement name for the illegitimate silicoflagellate genus Distephanus (Dictyochophyceae)
Tập 201 Số 3 - Trang 177
Stephanocha nom. nov. (Silicoflagellata, Dictyochophyceae) is herein proposed as
a replacement name for the illegitimate genus name Distephanus, which is a later
homonym of Distephanus, a flowering plant. The old generic description is
emended, with S. rotunda as the designated type, and new combinations are made
for all bona fide silicoflagellate taxa previously assigned (including those
tentativ...
Parental origin and genome evolution of several Eurasian hexaploid species of Chenopodium (Chenopodiaceae)
Tập 392 Số 3 - Trang 163
Hybridization and polyploidization appear to be ubiquitous in the evolution of
Chenopodium s.s., but the origin and the evolutionary history of the polyploid
chenopods is still poorly understood. Phylogenetic analyses of DNA sequences of
nrITS, four plastid regions, and 5S rDNA spacer region (NTS) of five Eurasian
hexaploid chenopods (2n = 6x = 54), C. album, C. giganteum, C. pedunculare C.
formos...

Asterochloris sejongensis sp. nov. (Trebouxiophyceae, Chlorophyta) from King George Island, Antarctica
Tập 295 Số 1 - Trang 60
The new species Asterochloris sejongensis sp. nov. has been collected from four
localities of King George Island, Antarctica, and is described as a phycobiont
of the lichen species Cladonia pyxidata and Sphaerophorus globosus. This
discovery is based on morphological and molecular data obtained using light
microscopy, confocal laser microscopy, transmission electron microscopy, and two
molecular m...
Hypnea wynnei and Hypnea yokoyana (Cystocloniaceae, Rhodophyta), two new species revealed by a DNA barcoding survey on the Brazilian coast
Tập 268 Số 2 - Trang 123
Two new species of the red algal genus Hypnea (Gigartinales) are described for
the southeastern coast of Brazil based on three molecular markers (COI-5P, rbcL
and UPA), detailed morphological analysis, and comparison with closely related
species. These species were named H. wynnei Nauer, Cassano & M.C. Oliveira and
H. yokoyana Nauer, Cassano & M.C. Oliveira. Hypnea wynnei is characterized
primaril...
Revision of Hygrochilus (Orchidaceae: Epidendroideae: Aeridinae) and a molecular phylogenetic analysis
Tập 159 Số 4 - Trang 256
Hygrochilus and Sedirea are genera of orchids with only three species endemic to
Asia. An analysis of ITS and five plastid regions using parsimony, maximum
likelihood, and Bayesian methods obtain clear evidence that Sedirea is nested
within and should be considered synonymous with Hygrochilus. We adopt a broadly
defined Hygrochilus characterized by possession of four pollinia. A new
combination, n...
A New Species of Eriosema (Leguminosae, Papilionoideae, Phaseoleae) from Mato Grosso do Sul, Brazil, with a Secretory Structure Novel to the Genus
Tập 263 Số 2 - Trang 122
Eriosema grearii, a new species for the genus (Leguminosae, Papilionoideae,
Phaseoleae, Cajaninae), is described and illustrated. Similar to E.
heterophyllum, it differs from it morphologically by the free (vs. joined)
stipules, lax flowers distributed along the inflorescence axis (vs. congested
and concentrated at its apex), inflorescences not opposite to the leaves (vs.
opposite), and leaflets w...
A new species of Arisaema (Araceae) from Vietnam
Tập 277 Số 1 - Trang 90–94 - 2016
Arisaema langbiangense (Araceae) is described and illustrated as a new species
from Langbiang Mountain, Bidoup-Nui Ba National Park, Lac Duong District, Lam
Dong Province, Vietnam. A morphological comparison between the new species and
its closest congeners and a key to all known species of Arisaema sect. Anomala
in Vietnam are given.
