Two key characters proposed to distinguish Lecomtia from the other sections of Camellia were its possession of 3 sepals and 6 petals. However, field photos of the fresh type material (Luu Hong Truong, Nguyen Quoc Dat, G. Orel &amp; A. S. Curry 1257, SGN! &amp; NSW!) (Fig. 1) and a later collection (Khuong Huu Thang &amp; Luu Hong Truong BGM2025-1, SGN!) confirm that C. campanulata actually possesses 5 sepals and 6–8 petals. Furthermore, the other defining features of Lecomtia —including narrowly elliptic to very narrow elliptic leaves; axillary or terminal, pedunculate, campanulate, and solitary flowers; numerous stamens; free styles with proximal fine pubescence; and a densely tomentose ovary—align with the diagnostic characteristics of section Piquetia .</p><p>Given these findings, it is reasonable to treat section Lecomtia as a heterotypic synonym of section Piquetia, following Article 11.4 of the International Code of Nomenclature for Algae, Fungi, and Plants (Shenzhen Code) (Turland et al. 2018). This conclusion is consistent with Doudkin et al. (2023), who also transferred C. campanulata to Piquetia . Additionally, it is noteworthy that all known species of section Piquetia uniformly possess five sepals.</p><p>Camellia cattienensis Orel (2012: 566) . Type:— VIETNAM. Lam Dong Province: margem do rio Dong Nai, terra firme, 19 December 2007, G. Orel, G. Richards, M. Richards &amp; staff of Cat Tien National Park Orel 0711 (holotype NSW!; isotypes NSW!, HN)</p><p>= Camellia campanulata Orel, Curry &amp; Luu (Orel &amp; Curry 2015: 154), syn. nov. Type: — VIETNAM. Binh Phuoc Province: Bu Gia Map National Park, about 1.0 km from Cambodian border, 18 December 2011, Luu Hong Truong, Nguyen Quoc Dat, G. Orel &amp; A.S. Curry 1257 (holotype SGN!; isotype NSW!).</p><p>= Camellia longii Orel &amp; Luu (Orel et al. 2014: 46), syn. nov. Type: — VIETNAM. Lam Dong Province: Cat Tien National Park, 10 September 2009, Vu Ngoc Long CT4 (holotype SGN!, paratypes NSW!, SGN!).</p><p>Notes:— Camellia cattienensis was initially placed in section Archaecamellia Sealy (1958: 108) (Orel &amp; Wilson 2012) before it was recently reassigned, along with C. campanulata, to section Piquetia (Doudkin et al. 2023) . Camellia longii was described from Cat Tien National Park in Lam Dong Province, which is the same type locality as C. cattienensis . A detailed comparison of the protologues reveals no significant morphological differences that could distinguish these three species. Their similarity is further evidenced in Orel and Curry (2015), where they are redescribed in detail, complete with photographs taken from type specimens. Additionally, it is noted that the type specimens of C. campanulata were actually collected on December 18, 2011, rather than July 2011 as stated in the protologue.</p><p>According to Article 11.4 of the International Code of Nomenclature for Algae, Fungi, and Plants (Shenzhen Code) (Turland et al. 2018), the name C. cattienensis has priority over C. campanulata and C. longii due to earlier publication. Consequently, C. campanulata and C. longii are treated here as heterotypic synonyms of C. cattienensis .</p><p>Additional examined collections:— VIETNAM.

It grows on wet, fertile soils along streams under the canopy of a tropical evergreen broad-leaved forest.</p><p>IUCN Red List Category: — The new species is known from a single population consisting of fewer than 20 mature individuals. No immediate threats to its survival have been identified; however, extensive botanical surveys conducted over the past five years across the 20,937.7-hectare Ta Dung National Park failed to locate any additional populations. The park experienced intensive logging in the past and is currently surrounded by large-scale agricultural development, leading to substantial habitat loss for the species. Its current Extent of Occurrence (EOO) and Area of Occupancy (AOO) are estimated to be less than 2 km ². Given these conditions, the species clearly meets the criteria for classification as Critically Endangered under any of the following IUCN criteria: B1 &amp; B2a,b; C2a(i); or D, according to the Red List Categories and Criteria (Standards and Petitions Subcommittee, 2024).</p><p>Etymology: — The species is named after its type locality, Dak Plao Village, which was historically inhabited by the ethnic Ma community but was submerged due to the construction of Dong Nai 3 Hydropower Plant. The recommended common names are Dak Plao camellia (English) and Trà my Đăk Plao (Vietnamese).</p><p>Notes:— Camellia dakplaoensis is reasonably placed within section Piquetia based on its salient morphological characteristics, which include: large leaves, 2–6 nodding and pedicellate flowers borne on short shoots in the axils of the leaves, several bracts, stout and upward-thickened pedicel, 4–5 bracteoles, 5 persistent sepals, 10–11 petals, filaments free above their union with the petals, and a densely hairy ovary. Within the section, it is most morphologically similar to C. langbianensis (Gagnepain 1939, Pham-Hoang 1991, Quach et al. 2021), though the two species can be distinguished as detailed in the diagnosis. Our field observations and personal communication with Dr. Quach confirm that the filaments of C. langbianensis are distinctly bi-colored, i.e., predominantly orange-red at the base (covering approximately the basal two-thirds to three-quarters), and yellow toward the apex (Fig. 3). This contrasts with the description in Quach et al. (2021), which reported entirely yellow filaments—a discrepancy attributable to the examination of withered specimens.</p><p>Camellia dakplaoensis also bears morphological similarities to C. proensis, as both species share a comparable overall appearance in terms of trees and flowers. Nonetheless, the latter can be differentiated by its larger leaves (33–35 × 7.5–8.5 cm versus 20–32 × 5–5.5 cm in C. dakplaoensis); 2–3 bracteoles (versus 4–5); hemispherical sepals with a rounded apex (versus ovate sepals with a cuspidate apex); 10–11 greenish-yellowish petals (versus petals 5–6, plain yellow); tomentose hairs on the basal half of the styles (versus hairs covering the basal 2/3 to 3/4); and larger fruits measuring 4.0– 5.5 cm high, 8.5–10.0 cm in diameter, with slight five-ridges (versus 2.5–3.5 cm high, 4.5–6.0 cm in diameter, with distinct 10–12 ridges). Morphological comparison between C. dakplaoensis and its close congeners is summarized in Table 1.</p></div>	https://treatment.plazi.org/id/FC4445304122FF99FF5DB8FCFE56CCC8	Public Domain	No known copyright restrictions apply.
