Camellia Oconoriana (Theaceae), a New Species From Vietnam

Abstract

The new species Camellia oconoriana Orel, Curry & Luu (Theaceae), endemic to Lam Dong Province, Vietnam, is described and illustrated. It is compared to Camellia species in sections Archaecamellia, Stereocarpus, Piquetia and Chrysantha. Morphological evidence supports a transitional placement in Camellia sect. Chrysantha ser. Chrysanthae.

Camellia puhoatensis (Sect. Archecamellia – Theaceae), a new species from Vietnam

“…The general introduction to the genus, with particular focus on Vietnam, was given in recent publications by various authors (e.g. Orel et al 2012Orel et al , 2013Orel et al , 2014aLuong et al 2016a;Nguyen et al 2018;Pham et al 2019;Do et al 2019a, b). So far, more than 75 species of Camellia have been reported in Vietnam, with many localised endemic species (e.g.…”

“…So far, more than 75 species of Camellia have been reported in Vietnam, with many localised endemic species (e.g. Pitard 1910;Gagnepain 1941;Rosmann 1999;Tran 1998a, b;Pham 2000;Hakoda and Tran 2001;Hakoda et al 2007;Orel 2006;Orel andWilson 2010a, b, 2012a, b;Orel and Curry 2014;Orel et al 2012Orel et al , 2013Orel et al , 2014aLuong 2012, 2013;Le 2013, 2015;Luu et al 2015Luu et al , 2018Luong et al 2016a, b;Le et al 2017;Nguyen et al 2018;Pham et al 2019;Do et al 2019a, b), but the actual number is expected to be higher in the near future Luong 2016, Do et al 2019b).…”

Camellia velutina (Theaceae, Sect. Chrysantha), a new species from northern Vietnam

“…Regions of Southern China and Northern Vietnam represent richest area for the genus diversity (Chang & Bartholomew, 1984). In Vietnam until now were reported 34 species (Pham, 1999;Orel et al, 2013 ; . Most Camellia species occurring in Vietnam have yellow flowers and belong to the section Chrysantha Chang (1979).…”

Camellia debaoensis (Theaceae), a new species of yellow camellia from limestone karsts in southwestern China

“…In recent years, many new species of yellow camellia have been reported from northern Vietnam and southern China (e.g. Tran and Nguyet 2005; Orel 2006; Orel and Wilson 2010, 2012; Orel et al 2012, 2013, 2014a, b; Tran et al 2012; Tran and Luong 2013; Huang et al 2014; Orel and Curry 2015; Tran and Le 2015; Luu et al 2015; Dung et al 2016; Luong and Le 2016; Luong et al 2016a, b; Le et al 2017; Nguyen et al 2018; Liu et al 2019), increasing the total to more than 50 species (Tran et al 2019) and making northern Vietnam another center of yellow camellia diversity. Generally, yellow camellias are rare and highly endemic due to their small population, narrow distribution and excessive gathering.…”
