Previously, S. corniculata was reported only from Kolombang- ara Island (Solomon Islands), Waigeo Island (New Guinea) and Obi and Aru islands (the Moluccas). We also update a description of its morphology, in particular on stylar characteristics based on new materi- als. A key to the Japanese species of Sciaphila based on total flower and stylar characteristics is also pro- vided for easy identification of these rare mycoheterotrophic plants.

Lam1,2,y, Marybel Soto Gomez1,2,y, and Sean W.

Accepted: July 8, 2015 Data deposition: The genomes and gene sequences have been deposited at GenBank under the accession numbers KP462882, KR902497, and KT204539-KT205273. Abstract The enigmatic monocot family Triuridaceae provides a potentially useful model system for studying the effects of an ancient loss of photosynthesis on the plant plastid genome, as all of its members are mycoheterotrophic and achlorophyllous. However, few studies have placed the family in a comparative context, and its phylogenetic placement is only partly resolved. It was also unclear whether any taxa in this family have retained a plastid genome. Here, we used genome survey sequencing to retrieve plastid genome data for Sciaphila densiflora (Triuridaceae) and ten autotrophic relatives in the orders Dioscoreales and Pandanales. We recovered a highly reduced plastome for Sciaphila that is nearly colinear with Carludovica palmata, a photosynthetic relative that belongs to its sister group in Pandanales, Cyclanthaceae–Pandanaceae. This phylogenetic placement is well supported and robust to a broad range of analytical assumptions in maximum-likelihood inference, and is congruent with recent findings based on nuclear and mitochondrial evidence. The 28 genes retained in the S.

This is an important finding in relation to the flora of Korea, as species of the genus Sciaphila are concentrated mainly in Indonesia and Malaysia. Few species are found on the mainland of Asia, in Japan, Taiwan, China (Hainan), tropical Africa, Australia, and on the Pacific islands. In this paper, the species S. secundiflora is described and illustrated as a new record from Korea. In addition, we suggest that the species of the genus Sciaphila should be protected with regard to its habitat characteristics and for its phytogeographic and climatic significance.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Monocot genomic diversity includes striking variation at many levels. This paper compares various genomic characters (e.g., range of chromosome numbers and ploidy levels, occurrence of endopolyploidy, GC content, chromosome packaging and organization, genome size) between monocots and the remaining angiosperms to discern just how distinctive monocot genomes are. One of the most notable features of monocots is their wide range and diversity of genome sizes, including the species with the largest genome so far reported in plants. This genomic character is analysed in greater detail, within a phylogenetic context. By surveying available genome size and chromosome data it is apparent that different monocot orders follow distinctive modes of genome size and chromosome evolution.

Nishioka, is described and illustrated from Ishigaki Island, Okinawa Prefecture, Japan. The new species is similar to S. arfakiana in having a stipitate globose to ellipsoid knob without hairs in apices of all male perianth segments. However, it is clearly distinguishable by its shorter pedicel, filament- connective not extended and thick stem. A key to the Japanese Sciaphila based on the whole flower characteristics and stylar characteristics, are provided for easy identification of these rare mycoheterotrophic plants. Keywords: Distribution, mycoheterotrophic plants, new species, Sciaphila, taxonomy, Triuridaceae, Ryukyu Introduction The Triuridaceae is a family of fully mycoheterotrophic plants that grow in the deep shade of pantropical ever-wet forests throughout the subtropical and temperate regions of Argentina, Paraguay, and Japan (Maas-van de Kamer & Weustenfeld 1998, van de Meerendonk 1984). Recent molecular phylogenetic studies have shown that the Triuridaceae, which comprises approximately 50 species within 11 genera, constitute a single clade within the Pandanales (Davis et al. 2004, Mennes et al.
