Three new species of Aulonemia (Poaceae: Bambusoideae) from the Brazilian Atlantic rainforest
Phytotaxa - Tập 156 Số 4 - Trang 235
Three new Brazilian species of Aulonemia, a Neotropical woody bamboo genus, are
described and illustrated: Aulonemia cincta, with its distinctive corky girdles;
Aulonemia prolifera, characterized, among other Brazilian congeners, by its
fimbriate leaf sheaths; and Aulonemia soderstromii, with its conspicuous cluster
of spreading fimbriae. These new species all propagate by amphipodial rhizomes,
an...
Parental origin and genome evolution of several Eurasian hexaploid species of Chenopodium (Chenopodiaceae)
Phytotaxa - 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...
Eriosema elegans (Leguminosae, Papilionoideae): A new species from the Highlands of Goiás State, Brazil
Phytotaxa - Tập 296 Số 1 - Trang 81
During a taxonomic study of Eriosema in Brazil, a new species was discovered
from the Chapada dos Veadeiros National Park, Goiás State. Eriosema elegans is
herein described and illustrated and its morphological affinities with related
species discussed. The geographical distribution, conservation status, and
information about flowering and fruiting are provided. Also, a study of
secretory structur...
A New Species of Eriosema (Leguminosae, Papilionoideae, Phaseoleae) from Mato Grosso do Sul, Brazil, with a Secretory Structure Novel to the Genus
Phytotaxa - 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 Eriosema (Leguminosae, Papilionoideae, Phaseoleae) from Minas Gerais, Brazil
Phytotaxa - Tập 178 Số 3 - Trang 229
Eriosema tozziae, a new species of Leguminosae (Papilionoideae, Phaseoleae,
Cajaninae) from Minas Gerais is described and illustrated. Similar to E.
defoliatum, it differs morphologically from the latter by the persistent leaves
in the reproductive phase (vs. caducous in E. defoliatum) and the shorter
inflorescences (10–13 cm long vs. 15–30 cm long in E. defoliatum). An
identification key for the ...
Asterochloris sejongensis sp. nov. (Trebouxiophyceae, Chlorophyta) from King George Island, Antarctica
Phytotaxa - 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...
Cyrtandromoea grandiflora, a new generic record for Vietnam, and a key to Vietnamese Phrymaceae
Phytotaxa - - 2023
Cyrtandromoea grandiflora is reported from Dien Bien and Lai Chau provinces in
Northern Vietnam, representing the first record of this species and the genus
Cyrtandromoea in the country. Detailed photographic illustrations of studied
specimens are provided. A key to the Vietnamese genera and species of Phrymaceae
is presented.

A new species of Arisaema (Araceae) from Vietnam
Phytotaxa - 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.

Stephanocha nom. nov., a replacement name for the illegitimate silicoflagellate genus Distephanus (Dictyochophyceae)
Phytotaxa - 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...
<p><strong>The phylogenetic position and taxonomic status of the Southeast and South Asian bamboo genera <em>Neohouzeaua</em> and <em>Ochlandra</em> (Poaceae: Bambusoideae) </strong></p>
Phytotaxa - Tập 472 Số 2 - Trang 107-122
Among the tropical woody bamboos, the Melocanninae is one of the most clearly
recognized subtribes morphologically and has also been consistently well
delimited in molecular phylogenetic work. The relationships among those genera
in this subtribe, however, have been contentious because of poorly understood
generic delimitations, in part due to poor specimen material or insufficiently
assessed morp...
