The genus Aspidistra Ker-Gawler (1822: t. 628) (Asparagaceae) is native to eastern and southeastern Asia and includes 170 species, of which more than 105 species occur in China (Liang & Tamura, 2000; Tillich, 2006, 2008, 2014; Averyanov et al. 2017, 2018, 2019; Lang et al. 1999; Li& Lin, 2016; Luo et al. 2018, Nong et al. 2018; Pan et al. 2019; Lin et al., 2019; Vislobokov et al. 2019a, 2019b). During a field trip in March 2019, an unusual species of Aspidistra with purple flowers was collected in Jiangjin District in southwest of Chongqing Municipality, China. After consulting herbarium specimens and relevant literature on Aspidistra, we reached the conclusion that the plant is a new species, here named Aspidistra jiangjinensis.

In April 2017, during an investigation at the Chongqing municipality, Qijiang district, we found some plants of Aspidistra Ker Gawler (1822: 628) with freshly opened flowers widespread on hillside shrub. This species was identified as new for science after studying relevant literature (Lang et al. 1982, 1984, 1999, Li et al. 1988, Wan et al. 1989, Tillich 2006, Tillich et al. 2012, Lin et al. 2013, He et al. 2015, Liang et al. 2016, Zhou et al. 2016, Pan et al. 2016, Vislobokov 2016, Zhong et al. 2016, Wang et al. 2017, Xu et al. 2017) and is described here.

Background and Aims: Cochemiea is a genus which currently comprises five species occurring in Mexico. It is morphologically characterized by cylindrical decumbent to prostrate stems and by a long red-scarlet zygomorphic perianth, presumably specialized for hummingbird pollination. As part ofthe ongoing taxonomic studies on the North Mexican flora, a population discovered by Thomas Linzen in 2012 in central Sinaloa (Mexico), previously identified as Mammillaria sp., actually refers to a Cochemiea species and cannot be ascribed to any of the known species of that genus. As a consequence,we here propose to describe this population as a a new species for science.Methods: The work is based on field surveys (autumn 2018 and spring 2019) in central Sinaloa, examination of herbarium specimens, and analysis of relevant literature. Its conservation status was assessed following the guidelines of the IUCN; AOO and EOO were calculated with the programGeoCAT.Key results: Cochemiea thomasii is described and illustrated from Sinaloa. The new species is morphologically similar to C. halei from which it differs by the hanging stems, the larger conical tubercles, less numerous and shorter central spines, and the ovoid fruits. A diagnostic key of the knownCochemiea species is included.Conclusions: Cochemiea thomasii is endemic to the state of Sinaloa where it occupies a small area. On the basis of the criteria B2a (geographic range) and C (small population) of IUCN, the new species can be assessed as Critically Endangered (CR) or Vulnerable (VU). Adopting the precautionary approach, Cochemiea thomasii is considered as Critically Endangered (CR).

The genus Aspidistra Ker-Gawler (1822: 628) (Asparagaceae) has its main centre of diversity in China and Vietnam. In recent years, many new species were discovered and described from that region, increasing the total number of species to over 120. In China, Aspidistra includes over 80 species and is mainly distributed in the southwest part of the country, especially in Guangxi Zhuang Autonomous Region (60 species) (Liang & Tamura 2000, Li 2004, Tillich 2005, 2008, Liu et al. 2011, Tillich et al. 2013, He et al. 2013, Lin et al. 2013a–b, 2014, Meng et al. 2014). When investigating medicinal plants in Qingshitan Natural Reserve, Lantian town, Lingchuan County, northeastern Guangxi in 2013, we collected an unusual Aspidistra specimen with linear leaves and urceolar perigone. In March 2014, we returned to the place for further observations of the species, the plant flowered regularly. After consulting herbarium specimens and relevant literature on Aspidistra, it became apparent that we had a new species at hand.

Aspidistra Ker Gawler (1822: 628) comprises more than 160 species in subtropical SE-Asia, mainly distributed in southern China and adjacent northern Vietnam (Li 2004, Tillich 2005, 2014). In recent years, many new species have been discovered and described from Guizhou Province, southwestern China (He et al. 2011a, 2011b, 2013, Liu et al. 2015, Sun et al. 2014, Xu et al. 2010, 2015a, 2015b). In May 2013, when investigating limestone plants in Guizhou province, we discovered an unusual Aspidistra Ker Gawl. at Dadaihe Karst Tiankeng (Tangbian, Pingtang county), showing dark purplish red flowers, but the pistil was wilted because the plant was at late stage of anthesis. Therefore plants were collected and transferred to the Guilin Botanical Garden, where they flowered next spring. In November 2015, the second author (Meng-Qi Han) collected again the same Aspidistra pecies at Anjiadong Karst Tiankeng (Tangbian). After consulting herbarium specimens and relevant literature on Aspidistra (Huang et al. 2015, Lin et al. 2015, Liang et al. 2016, Ly & Tillich 2016, Pan et al. 2016, Vislobokov et al. 2016), it turned out that the plant represents a new species, which we describe below.

During our fieldwork in the southwest Guangxi, China in January 2014, we found in the White-headed Langur National Nature Reserve an unusual Aspidistra Ker-Gawler (1822: 628) specimen with fruits and dried up flowers only, so we could not identify it without fresh flowers. In November, we returned to the place for further observations of the species, and found the plants with blackish purple, bell-shaped flowers. After consulting herbarium specimens and relevant literature on Aspidistra (Liang & Tamura 2000, Li 2004, Li & Wei 2003, Tillich 2005, 2008, Lin et al. 2009, 2010, 2012, 2013, Lin & Liu 2011, Liu et al. 2011, Tillich & Leong-Skornickova 2013, Hu et al. 2014, Meng et al. 2014, Vislobokov et al. 2014), it became apparent that this population is an undescribed species, and the valid name Aspidistra chongzuoensis was used, which is described below.

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.

Classiculasinensis, isolated from decaying leaves from Mozigou, Chongqing Municipality, China, is described as a new species. The new species is a member of basidiomycetous aquatic hyphomycetes which represent a small proportion of all aquatic hyphomycetes. This species falls within the genus Classicula (Classiculaceae, Pucciniomycotina) and is closely related to C.fluitans, based on multiple gene sequence analyses. Morphologically, it is characterised by the apical, hyaline, obclavate or navicular conidia with several hair-like lateral appendages and by its holoblastic and monoblastic conidiogenesis, with a flat un-thickened conidiogenous locus. Clamp connections and haustorial branches were often observed in culture.

Background and aims – The genus Anemopaegma (Bignoniaceae) includes around 47 species and has its centre of diversity in Brazil. Here, we describe and illustrate a new species from French Guiana, Anemopaegma kawense, and compare it to the two most similar species, A. foetidum and A. granvillei. We further assess the conservation status of all three species.Material and methods – Morphological descriptions are based on herbarium specimens deposited at BM, BR, CAY, INPA, K, MO, P, SPF, and U, and, in the case of the newly described species, also on field observations. The conservation status assessments follow the IUCN Red List criteria.Key results – Anemopaegma kawense differs from both A. foetidum and A. granvillei by its densely villose twigs, longitudinally plicate leaflets with secondary veins not or hardly prominent below, and tertiary veins impressed below. It is further separated from A. foetidum by the leaflets that are villose below and the calyx that is entirely pubescent outside. On the other hand, A. kawense differs from A. granvillei by the densely lepidote outer surface of the corolla, shorter petiolules, leaflets with midrib impressed above, shorter bracts and bracteoles, inflorescence peduncle exceeding the rachis, and pedicels densely puberulous, not lepidote or only sparsely so at the apex. This species is endemic to the Kaw Mountain in north-eastern French Guiana, where it grows in low stunted forest on laterite; it is assessed as Endangered according to the IUCN criteria. New descriptions are provided for A. granvillei, which is newly reported from Suriname, and for A. foetidum, which is newly reported from French Guiana; these two species are assessed as Endangered and Least Concern, respectively. Lectotypes are designated for A. maguirei, which is here synonymised with A. foetidum, and for A. umbellatum, another synonym of that species. A key to the 12 species of Anemopaegma occurring in the Guianas is presented.

Cyrtandra tempestii, a species endemic to the southeast coast of Taveuni, Fiji, is reevaluated in light of recent field collections and a thorough examination of herbarium specimens. A revised description of this species based on observations and morphological measurements from the field is presented here. Cyrtandra tuiwawai sp. nov. was formerly included under C. tempestii based on similarities in floral morphology and is described here as a new species endemic to the montane forests of Taveuni. Habitat preference, as well as morphological characters, distinguish the two species from one another. The addition of C. tuiwawai brings the total number of Cyrtandra species in Fiji to 42, and supports the need for continued fieldwork in the region.
