“…Most research concerns the analytical or separating study of the plant for its medicinal or nutrient ingredients, including the amino acids, vitamins, etc. Most previous research focus on leaves or flowers of Camellia nitidissima Chi [ 16 , 17 ]. Few reports have focused on the detection of amino acids of Camellia nitidissima Chi seeds.…”

Husk derived amino modified linear graphene nanocomposites (aLGN) with a diameter range of 80–300 nm and a length range of 100–300 μm were prepared by a modified Hummers method, ammonia treatment, NaBH4 reduction and phenylalanine induced assembly processes, etc. The resulting composites were characterized by transmission electron microscopy (TEM), atomic force microscopy (AFM), scanning electron microscopy (SEM), biological microscope (BM), and X-ray diffraction spectroscopy (XRD), etc. Investigations found that the aLGN can serve as the novel coating of stir bar sorptive extraction (SBSE) technology. By combing this technology with gas chromatography–mass spectrometry (GC-MS), the combined SBSE/GC-MS technology with an aLGN coating can detect seventeen kinds of amino acids of Camellia nitidissima Chi seeds, including Ala, Gly, Thr, Ser, Val, Leu, Ile, Cys, Pro, Met, Asp, Phe, Glu, Lys, Tyr, His, and Arg. Compared to a conventional polydimethylsiloxane (PDMS) coating, an aLGN coating for SBSE exhibited a better thermal desorption performance, better analytes fragmentation depressing efficiencies, higher peak intensities, and superior amino acid discrimination, leading to a practicable and highly distinguishable method for the variable amino acid detection of Camellia nitidissima Chi seeds.

Luteopallida, C. pubipetala and C. luongii (data partly based on Luong et al 2016, Ninh and Ninh 2015, Chang and Bartholomew 1984 (Chang and Bartholomew, 1984), including medium to large yellow pedicellate flowers, 5 bracts, 7 persistent sepals, 12 petals, stamens in 4 whorls with basally connate filaments in the outer whorl and free filaments in the inner whorls, a 3-locular glabrous ovary, and styles cleft into 3 parts. The flowers of Camellia tuyenquangensis differ from other species in section Chrysantha only in having both axillary and terminal (not strictly axillary) flowers and 4-5 (not 5-7) bracteoles.…”

“…In the world, the number of species in Camellia genus was estimated to be from 120 to 300 (Sealy, 1958;Chang and Bartholomew 1984;Ming and Bartholomew 2007) and this genus is the largest genus of the Theaceae. Recently, many additional new species of Camellia have been discovered and described from Vietnam (Ninh et al, 2012;Orel et al, 2012Ninh and Dung, 2013;Ninh and Ninh, 2015;Luong et al, 2016).…”

Camellia tuyenquangensis (Theaceae), a new yellow species of camellia from the Chiem Hoa district of the Tuyen Quang province in Vietnam, is described and illustrated. Camellia tuyenquangensis is similar to Camellia luongii but different from the latter species in several morphological features: leaves oblong-ovate to narrow elliptic; flowers 1-2; bracteoles glabrous on both sides; sepal margins ciliate; style cleft one half of the length. The morphological data provisionally support its placement in Camellia sect. Chrysantha Chang.

“…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.…”

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.
