DOI: 10.3897/phytokeys.239.113878

Authors: Dongwei Zhao

Abstract: Natural plants of Camellia (Theaceae) in Thailand are taxonomically revised with a key, a distribution map, descriptions, specimens examined, and figures of living plants and/or dry specimens. Nine taxa comprising seven species and two varieties are recognized, including C. caudata, C. connata, C. furfuracea, C. kissi, C. kissi var. confusa, C. laotica, C. sinensis var. assamica, C. suddeeana, and C. taliensis. Camellia caudata and C. laotica are new records to Thailand, and C. connata and C. suddeeana are endemic to the country. Formerly recorded C. pleurocarpa and C. tenii are excluded from Thai flora because of misidentification, and C. oleifera and C. sinensis are merely cultivated in the country. Morphological descriptions of C. connata and C. laotica are improved based on additional collections examined.

Camellia zijinica (Theaceae), a new species endemic to Danxia landscape from Guangdong Province, China https://phytokeys.pensoft.net/article/114768/ PhytoKeys 237: 245-255

DOI: 10.3897/phytokeys.237.114768

Authors: Min Lin, Qin-Liang Ye, Zhi-Jian Zhang, Wen-Bo Liao, Qiang Fan

Abstract: A new species of the genus Camellia (Theaceae), Camellia zijinica, discovered in the Danxia landscape from Guangdong Province, China, is characterized and illustrated. Phylogenetic analysis based on chloroplast genomes suggested its affinity with C. drupifera, C. oleifera and C. fluviatilis, however, it morphologically differs from all of the latter by leaf shape and size. Phonologically, it most closely resembles C. microphylla, but can be distinguished from the latter by its young branchlets glabrous (vs. densely pubescent), fewer bracteoles and sepals, diverse leaf shape, midvein raised slightly with sparsely pubescent or glabrous (vs. prominently with densely pubescent) and leaf adaxially matt (vs. vernicose) when dried. By morphological and molecular analyses, Camellia zijinica represented a distinct new species of C. sect. Paracamellia.

Taxonomic revision of Camellia langbianensis (Theaceae) with four new synonyms https://phytokeys.pensoft.net/article/110218/ PhytoKeys 234: 275-281

DOI: 10.3897/phytokeys.234.110218

Authors: Dongwei Zhao

Abstract: Based on analysis of morphologically diagnostic characters, Camellia langbianensis, a yellow camellia native to southern Vietnam, is taxonomically revised to include four new heterotypic synonyms: C. decora, C. dongnaiensis, C. oconoriana and C. tadungensis. Camellia vidalii is retained in the synonymy of C. langbianensis. Updated description and distribution map for C. langbianensis are provided.

Nomenclatural notes and typification of three synonyms of Camellia (Theaceae) https://phytokeys.pensoft.net/article/78810/ PhytoKeys 193: 1-8

DOI: 10.3897/phytokeys.193.78810

Authors: Dongwei Zhao

Abstract: All the known generic synonyms of Camellia are summarized with their types clarified. Camelliastrum and Desmitus are lectotypified and Salceda is neotypified. “Kailosocarpus” and “Parapiquetia” were not validly published, Theaphylla and Tsia are illegitimate replacement names for Thea, and Kemelia and Tsubaki are illegitimate replacement names for Camellia. Nomenclatural notes on Theopsis and its type are also provided.

Camellia puhoatensis (Sect. Archecamellia – Theaceae), a new species from Vietnam https://phytokeys.pensoft.net/article/49388/ PhytoKeys 153: 1-11

DOI: 10.3897/phytokeys.153.49388

Authors: Danh-Hùng Nguyễn, Văn-Dũng Lương, Thị-Hương Lê, Quốc-Thành Trần, Ngọc-Đài Đỗ, Ngọc-Sâm Lý

Abstract: A new species of Theaceae, Camellia puhoatensis N.S. Lý, V.D. Luong, T.H. Le, D.H. Nguyen & N.D. Do, sp. nov., is described and illustrated from Nghe An Province, North Central Coastal Region, Vietnam. It is most similar to C. chrysanthoides, C. flavida and C. petelotii within sect. Archecamellia in shape and colouration of leaf, petal, ovary and glabrous stamen, but differs by its young puberulous shoot, mature leaf sparsely puberulous abaxially and leaf base rounded or broadly obtuse, petiole and pedicel puberulous, tepals 12–13, ovary and style pubescent. The comparison between the new species and C. velutina and C. dormoyana is presented. Data on distribution, ecology, phenology, use and provisional conservation assessment of the new species are given along with an illustration and a colour plate.

Camellia debaoensis (Theaceae), a new species of yellow camellia from limestone karsts in southwestern China https://phytokeys.pensoft.net/article/38756/ PhytoKeys 135: 49-58

DOI: 10.3897/phytokeys.135.38756

Authors: Renchuan Hu, Sujuan Wei, Yongqing Liufu, Yunkai Nong, Wei Fang

Abstract: Camellia debaoensis R.C.Hu & Y.Q.Liufu, sp. nov. is described and illustrated as a new species from southwestern Guangxi, China. It is morphologically similar to Camellia pubipetala Y. Wan & S. Z. Huang, C. mingii S.X. Yang and C. tuyenquangensis D.V. Luong, N.N.H. Le & N. Tran, but it differs from these species in having glabrous young branches, glabrous petiole, glabrous sepals, glabrous petals, glabrous stamens and glabrous ovary, 10 petals, cylindrical ovary and style 3-lobed to 1/6 style length.
