Aspidistra latistyla, (Asparagaceae), a new Chinese species, is described and illustrated here. This new species is similar to A. longipetala in the shape of the flowers, but can be clearly distinguished by its taller leaves, the perianth lobes shorter than tube, stamens inserted in the upper-middle of perianth tube and the stigma cylindrical, 8–10 mm long, 7–9 mm in diameter.

A New Species

Gastrodia Brown (1810: 330; Gastrodieae, Epidendroideae) comprises mycoheterotrophic orchids from throughout the temperate and tropical regions of Asia, Oceania, Madagascar and Africa (Chung & Hsu 2006, Cribb et al. 2010, Tan et al. 2012). The genus is characterized by fleshy tubers, as well as the absence of normal leaves, union of sepals and petals and two mealy pollinia that lack caudicles. Furthermore, many Gastrodia species within section Codonanthus (Schlechter 1911, Tuyama 1967) produce inflorescences that are only 3–15 cm in length at flowering (Chung & Hsu 2006) and, owing to their short flowering seasons and dwarf habits, are seldom noticed when flowering (Tuyama 1982, Suetsugu et al. 2012). The identification of Gastrodia species requires detailed observation of floral features, such as lip and column morphology, that are hidden within the perianth tube.

A New Species

Discovery of populations south of Elandshaai of a small-flowered plant closely allied to Babiana ringens led to a critical re-evaluation of this sunbird-pollinated Western Cape species. We conclude that these populations represent a new species, B. avicularis, recognized by long, arching, subterete leaves, and flowers with the lower part of the perianth tube sigmoid and ± 4 mm long, a dorsal tepal 15-18 mm long, pale green lower tepals directed forward, and a style dividing below the bases of the anthers. In addition, the southern coastal populations of B. ringens merit recognition as a separate subsp. australis, recognized by the smaller flower, filaments not reaching the apex of the dorsal tepal and the style dividing at or below the bases of the anthers. Field work along the Western Cape coast also resulted in the discovery of a new species, B. teretifolia, allied to the distinctive B. brachystachys but differing from that species in the linear, spreading, twisted tepals, filaments 12 mm long, white anthers 5.5-6.0 mm long, and the style dividing opposite the anther tips, with branches ± 5 mm long and notched at the tips.

A New Species

The genus Aspidistra is the most diverse in southern China and northern Vietnam. We describe a new species Aspidistra xuansonensis from northern Vietnam including two varieties: A. xuansonensis var. xuansonensis with greenish white perianth and A. xuansonensis var. violiflora with purple perianth. We present DNA barcoding data of plastid psbA-trnH and nuclear 5SNTS regions for these two varieties in comparison with three other species of Aspidistra. Morphology of monopodial shoots of A. xuansonensis is described in detail. A. xuansonensis resembles recently described A. lingyunensis but differs in longer leaf petioles, longer lamina, perianth tube shape (tubular, widened at the base vs. funnel-shaped), higher anther position, and pistil shape (suddenly obconic to nearly umbrella-shaped vs. obconic gradually widened to stigma).

A new species, Gastrodia kuroshimensis (Orchidaceae: Epidendroideae: Gastrodieae), from Kuroshima Island, Kagoshima Prefecture, Japan, is described and illustrated. The outlined floral morphology indicates a close affinity to G. fontinalis, but it is easily distinguished by several characteristics, such as the cleistogamous floral condition, smaller perianth tube size and the anther cap joined with the column.

A new species of Cremastra (Orchidaceae), C. saprophytica, is described from Gifu Prefecture, Japan. The new species is similar to C. aphylla in having a leafless and mycoheterotrophic habit. However, it is distinguishable from C. aphylla by its green stem, more closed perianth tube, smaller lateral lobes of lip, smaller callus of lip positioned at base of the midlobe and absence of a rostellum and viscidium. An illustration and ecological information on the new species are provided. A key to the Cremastra species is also provided.

A New Species

A new species of Thismia (Thismiaceae), T. jianfenglingensis, is described and illustrated from Hainan Island, China. The new species is similar to T. hongkongensis, displaying a urecolate perianth tube, a loose dome with six perianth lobes, six stamens, and three stigmas. T. jianfenglingensis differs from T. hongkongensis in the color and morphology of perianth tube, the position of outer perianth lobes, the morphology and appendage of connective apex, the morphology of stigmas. The new species is only reported to occur on Hainan Island, China and it is proposed to be Vulnerable (VU) according to the IUCN criteria for the conservation status of plant species due to having a population with a very restricted area of occupancy or number of locations such that it is prone to become critically endangered or even extinct in a very short time period.

A New Species

Lachenalia Jacquin in Murray (1784: 314) is a deciduous, geophytic genus endemic to western, southern, southeastern and central South Africa and to western and southern Namibia (Duncan et al. 2005). All South African members produce leaves in the winter, including those from essentially summer-rainfall areas, and L. pearsonii (Glover 1915: 105) Barker (1969: 321) from southern Namibia is the only summer-growing species (Duncan & Condy 2013). Flower and seed characters are most important for identification of Lachenalia, especially perianth shape including the perianth tube shape and length, relative position of outer and inner tepals, stamen orientation, seed shape and strophiole length. A recent monograph of Lachenalia provided a new classification for the genus based on a phylogenetic study of morphological characters and recognized 133 species (Duncan 2012). Living material of a new species from the Namaqualand coastal plain became available for study in 2013, although pressed specimens were first gathered in 2006. The total number of species for the genus now stands at 134.

Litsea udayanii, a new species of Lauraceae from the Anamalai phytogeographical zone of southern Western Ghats is described and illustrated here. The new species resembles L. cubeba in its clustered inflorescence and L. beddomei in fruits. Litsea udayanii differs from L. cubeba by its coriaceous leaves, 12 staminodes in the female flowers, ellipsoid fruits, and an enlarged and cup-shaped perianth tube; it differs from L. beddomei by its elliptic-oblong leaves with cuneate to rounded base and abaxially prominent tertiary veins, and by its clustered inflorescence. In contrast, L. cubeba is characterized by chartaceous leaves, 8–9 staminodes in the female flowers, subglobose fruits, and a small and flattened perianth tube and L. beddomei is distinguished by linear-oblong leaves with acute to attenuate base and abaxially inconspicuous tertiary veins, and by inflorescences arranged on 1–5 cm long brachyblasts.

Aspidistra yuelushanensis, a new species of Asparagaceae is described and illustrated from typical hilly red soil region in Hunan Province, central southern China. This novelty is similar to A. chishuiensis by sharing purplish-red and campanulate perianth, but differs from the latter by its stamens inserted at the base (vs. inserted at the middle) of perianth tube, filaments spreading horizontally or slightly upward and enlarged (vs. sessile), perianth lobes slightly outcurved (vs. slightly incurved). It also resembles A. tenuifolia and A. pingfaensis, but differs from the latter two in its leave blade elliptic-lanceolate (vs. narrowly long to ribbon-shaped and linear, respectively), stigma 5 (vs. 7–8 and 8–9, respectively) mm in diameter. A key to the species of Aspidistra in Hunan province is provided.
