Hemiboea malipoensis, a new species of Gesneriaceae from southeastern Yunnan, China

Abstract

Hemiboea malipoensis, a new species of Gesneriaceae from southeastern Yunnan, China, is here described and illustrated. Based on morphological and molecular evidence, it was found to be similar to H. magnibracteata and H. cavaleriei var. paucinervis by conspicuous involucre and anthers fused by entire adaxial surfaces, but can be easily distinguished from the latter two species by its manificat spherical involucre, 3.5–4.5 cm in diameter, cymes with 4–10 flowers, corolla larger, 4.5–5.5 cm long, pale yellow-yellow, corolla tube glabrous, Calyx lanceolate, 5-parted from the base.

Hemiboea yongfuensis (Gesneriaceae): a cryptic and critically endangered new species from North Guangxi, China

“…Total genomic DNA was extracted using the CTAB method (Doyle and Doyle ). The ITS and trnL‐F were selected for phylogenetic analyses as these two loci are the most frequently used in phylogenetic studies of Hemiboea and other Gesneriaceae (Zhang et al , Huang et al , Lu et al ). The PCR amplifications and sequencing procedures were according to those described in Guo et al ().…”

“…Since the previous comprehensive taxonomic revision by Li and Wang () in which 23 species and five varieties were recognized, Hemiboea has increased to at least 37 species and five varieties. Apart from the two Metabriggsia Wang () species which were transferred to Hemiboea by Weber et al (), ten species have been newly found in Guangxi, Guizhou and Yunnan in recent years (Xu et al , , Wen et al , , Pan et al , Zhou et al , Zhang et al , Chen et al , Li et al , Wu et al ). Most if not all the newly described species have narrow or site‐endemic distribution and low abundance.…”

Hemiboea albiflora, a new species of Gesneriaceae from Guizhou, China

“…Clarke is a medium-sized genus of Gesneriaceae distributed in central to southern China, northern Vietnam and Southern Japan (Li and Wang 2004). Recently, nine new species and one new variety were found in Guangxi, Guizhou and Yunnan province of China (Li and Liu 2004; Wei 2010; Xu et al 2010, 2012; Huang et al 2011; Wen et al 2011, 2013; Pan et al 2012; Zhou et al 2013; Zhang et al 2014; Li et al 2018; Chen et al 2018). Meanwhile, Weber et al (2011) transferred two species of the Chinese endemic genus Metabriggsia W. T. Wang (1983) to Hemiboea , based on molecular and morphological evidence.…”

Hemiboea pterocaulis comb. et stat. nov. (Gesneriaceae), a new critically endangered species segregated from H. subcapitata

“…This conclusion was further corroborated a the molecular phylogeny, which resolved Metabriggsia taxa as nested within Hemiboea (Weber et al 2011). In addition, eight new species and one new variety have been described in recent years (Li and Liu 2004, Wei 2010, Xu et al 2010, Huang et al 2011, Wen et al 2011, Pan et al 2012, Zhou et al 2013, Zhang et al 2014. Thus, to date, a total of 33 species and six varieties have been recognised in the genus, with all except H. roseoalba S. B. Zhou, X. Hong & F. Wen listed in 'The international plant names index' (IPNI;  www.ipni.…”
