Acianthera sudae is newly described based on cultivated material from Brazil. It belongs to section Cryptophoranthae and differs from all others in this group by the larger flowers and sepals fused apically for more than half length, and a green-brown abaxial side of sepals with purple dots. Chromosome number (2n = 40) and genome size estimation (1C-value = 1.18 pg) is provided and its phylogenetic placement under the genus is supported with reconstruction of a molecular phylogeny using nuclear ribosomal ITS.

Andinia barbata is newly described based on cultivated material originally collected near Shaglli in Ecuador. It belongs to subgenus Aenigma and differs from all others in this group by the lanceolate lip, 2.5 times longer than wide, and unusually long and thick projections from the synsepal which gives a bearded appearance to the flowers. Phylogenetic placement under the genus is supported with reconstruction of a molecular phylogeny using nuclear ribosomal ITS and plastid matK regions and the genome size estimation (1C-value = 1.38 pg) is provided.

Changnienia Chien (1935: 89) is a monotypic genus of tribe Calypsoeae endemic to eastern and central China (Chen et al. 1999, 2009, Freudenstein 2005), previously with only the species C. amoena Chien (1935: 90), which was listed in the Chinese Redbook in 1992 (Fu 1992). Yang & Zhu (1984) reported a chromosome number for it of 2n=46. Sun et al. (2006) observed pollination and found that Bombus trifasciatus was its pollinator. Zhai et al. (2013) confirmed the phylogenetic placement of this species as a member of tribe Calypsoeae (sensu Pridgeon et al. 2005). A new species of Changnienia is described and illustrated here based on molecular and morphological evidence. It is discovered in Malipo, Yunnan Province, China.

Crocus heilbronniorum is described as a new species from Fethiye, Muğla province (SW Turkey). Diagnostic morphological characters, a full description and detailed illustrations are provided based on the type specimen and wild specimens. Morphologically, C. heilbronniorum is close to Crocus atrospermus, but the newly described species differs by its indistinct corm tunic neck, the presence of teeth on rings, basal leaf number and narrower leaves, star-like flowers, longer filaments, almost half length shorter anthers, and style always longer than stamens. Furthermore, Crocus heilbronniorum possesses a different chromosome number (2n = 2x = 12) with regard to C. atrospermus (2n = 10). In order to clarify the phylogenetic position of this species within Series Lyciotauri, data on ITS region sequences are also reported.

Abstract—A new species, Antrophyum nambanense, is described here based on the evidence from morphology and molecular phylogeny. Morphologically, short taeniform soral paraphyses and large fronds are the diagnostic characteristics of A. nambanense. Phylogenetically, it is most closely related to A. annamense, but can be readily distinguished from A. annamense by taeniform soral paraphyses (vs. filiform). We suggest A. nambanense is an allopolyploid of hybrid origin involving A. annamense and A. henryi, based on the evidence of morphology, phylogenetic position, chromosome number, and partially malformed spores. A description, photographs of key characters, distribution, conservation status, and ecology of the new species are presented. In addition, A. nambanense is also the first confirmed species with chlorophyllous spores in Antrophyum. Lastly, an updated key to all known Antrophyum species in Vietnam, including A. henryi as a new record for the country, is provided.

Campanula martinii a new species in the C. rotundifolia species complex, is here described. C. martinii is seemingly endemic to dolomitic cliffs and rocky places of the Prealps in Lombardia and Trentino-Alto Adige (northern Italy). The plants are robust with long hypogeal stolons, papillose ovary and patent to reflexed calyx teeth. This species is hexaploid with chromosome number 2n = 102. The taxonomic and phylogenetic placement of the new species is briefly discussed.

Pabstiella elegans is newly described based on cultivated material originally collected near Chaucha in Ecuador. It belongs to the group of small, creeping species of Pabstiella section Mentosae and differs from its closest relatives by the two-times larger flower and unusual colour of its sepals, which are creamy white with red dots. It also differs in the genome size (1C-value = 0.537 pg), which is 10.5% higher than its sister species, P. aryter. Phylogenetic placement is supported by an analysis based on nuclear ribosomal ITS and plastid matK regions.

Aspidistra revoluta (Asparagaceae) is described and illustrated as a new species from limestone areas in southern Chongqing Municipality, China. The new species can be distinguished from the other Aspidistra species by its unique umbrella-like pistil with large revolute stigma lobes that bent downwards and touch the base of the perigone. A detailed morphological comparison among A. revoluta, A. nanchuanensis and A. carnosa is provided. The pollen grains of A. revoluta are subspherical and inaperturate, with verrucous exine. The chromosome number is 2n = 38, and the karyotype is formulated as 2n = 22m + 6sm + 10st. The average length of chromosome complement is 4.50 μm, and the karyotype asymmetry indexes A1 and A2 are respectively 0.37±0.03 and 0.49±0.01.

Corydalis nanchuanensis (Papaveraceae), a new species from Nanchuan district in south-west Chongqing, China, is described and illustrated. Morphologically, the new species is similar to C. sheareri, a species mainly distributed in south China and Vietnam, in having conical corolla spurs, divided lower bracts, rounded stigmas, larger elaiosomes (usually longer than seeds), and tubers, but differs by having tapering-to-base (vs. uniformly sized) stems; entire (vs. usually crenate) leaf lobes, straight (vs. declined) pedicels in fruit, concave (vs. subacute) apices of outer petals, white (vs. usually purple) abaxial side of inner petals, and reticulate (vs. tuberculate) seeds.
