A New Species

A new species in Megasporaceae, Aspiciliella pakistanica is described and illustrated from Pakistan. A comparative morpho–anatomical study and ITS–based molecular analysis confirmed its position within the recently resurrected genus Aspiciliella. The taxon is characterized by whitish–grey thalli having large and thick areoles without pale lines on the surface, and a discontinuous algal layer arranged in groups of vertical rows. Its positioning in a separate branch in the phylogenetic tree also makes it distinct from the other known species of the genus.

A new species, Dichoropetalum viarium (Apiaceae), is described from the Lorestan Province, Western Iran. The new species differs from D. paucijugum, D. aromaticum, and D. chryseum in the height, shape, diameter, and branching of the stem, shape of the terminal leaf lobes, shape of the bracteoles, shape and size of the mericarps, and shape of the stylopodium. In addition, D. viarium is recognized as a separate species by molecular analysis of nrITS.

A new species of Amaranthaceae, Alternanthera kanhae, is described and illustrated from the bank of Sabarmati estuary in the state of Gujarat of Peninsular India. The new species is closely allied with A. caracasana and A. pungens but differs in many attributes. The identity of the newly proposed species is confirmed by molecular analysis of three chloroplast DNA (cpDNA) regions viz., rbcL, psbA–trnH and trnL–trnF. The sequences showed that A. kanhae has an independent lineage to that of its sister clade.

A New Species

Two species of Xanthagaricus discovered in Hubei Province of China are described based on the macro- and micromorphological features. Their identity is further supported by molecular analysis of the internal transcribed spacer (ITS) of the ribosomal RNA gene. The phylogeny obtained here showed that one of the Chinese species is nested in an exclusive clade which in combination with its striking morphological features, infers that it represents a new species, named X. ianthinus, while the other species is placed as a member in the X. epipastus clade. Descriptions are accompanied with illustrations of macro- and micromorphological characters and a discussion of related taxa is presented.

Primulina lianchengensis B.J.Ye & S.P.Chen (Gesneriaceae) is described and illustrated from Fujian Province in the Southeast of China. Then phylogenetic analyses of the genus were presented using nuclear ribosomal ITS and two plastid markers (atpB-rbcL and rpL32-trnL). Morphological analysis indicates that P. lianchengensis is similar to P. danxiaensis, P. depressa, P. lechangensis and P. yangshanensis, but it differs in the base and margin of leaf, petiole, bract, length and shape of corolla, numbers of staminodes and stigma lobe. Molecular analysis reveals that P. lianchengensis is genetically similar to P. danxiaensis and P. yangshanensis.

The genus Helosciadium has six species of which three have been identified in Portugal: H. nodiflorum, frequent and abundant in much of the territory, and H. inundatum and H. repens, with a scattered distribution in Portugal. In the present study, a new species, Helosciadium milfontinum, a seriously threatened plant endemic, rare and scarce that grows in the temporary ponds of the Vicentinan Coastal District is described and illustrated. Morphological characters and molecular analysis of nuclear internal transcribed spacers (ITS) and plastid regions (matK, rps16-trnK and trnL-F) confirm the existence of this new taxon. Conservation status and taxonomic relationships of the new species are examined.

A new species of Sciaphila (Triuridaceae), S. kozushimensis Suetsugu, is described from Kozu Island, Izu Islands, Japan. The new species is similar to S. tosaensis in having unisexual flowers (the female towards the base of the rachis), perianth-segments without any appendages and club-shaped style that is as long as or slightly exceeds ovary in the flowering stage. However, it is distinguishable by smaller male flowers, wide and acuminate male perianth segments and somewhat dissimilar perianth segments. An illustration and molecular analysis based on ITS sequences of the new species are provided. A key to the Japanese Sciaphila is also provided for identification of these rare mycoheterotrophic plants.

A New Species

Gnetum chinensesp. nov., a new lianoid species of Gnetaceae, is described from southwestern China. The new species is morphologically similar to G. montanum Markgr. in its oblong elliptic leaves and the ovoid to ellipsoid chlamydosperm, but differs from the latter by its shorter male spikes having fewer involucral collars (7–10 vs. 13–18 in G. montanum). We also did a new molecular analysis using one nuclear marker (i.e. nrITS) and four chloroplast markers (i.e. matK gene, rpoC1 intron, psbB-rps12 IGS, and trnF-trnV IGS). The result suggests that this specific clade is sister to a large clade consisting of all other known Chinese lianoid species of Gnetum except G. parvifolium (Warb.) W.C. Cheng.
