038E851F471D5070EEE76212FF2E0FD0.taxon	discussion	Notes. 1. Euphorbia bokorensis appears to occur throughout the Central Highlands of Vietnam. It is recorded from Kon Tum - Gia Lai and Langbian plateaus, and its occurence in Dak Lak plateau is highly probable. The findings are in line with the idea of Lim et al. (2021) that the species is widely distributed in the Eastern Indochina. 2. The Vietnamese material allows to describe certain morphological variation of E. bokorensis. The shape of leaf blade varies from oblanceolate to prominently obpandurate. Cyathophylls in some populations are significantly smaller than those in the type material: in Nuraliev, Lyskov NUR 3262, they are 1.5 – 3 mm long (vs. ca. 4 mm long in the protologue); in the photo record Nuraliev NUR 836 a, they are scale-like, hardly exceed the involucre and do not provide showy appearance to the cyathium. Although the cyathophylls are stated to be basally fused in the protologue, they are free from each other in the specimens from Vietnam, and they are also likely to be free in the type material. Short hairs are present in the axils of cyathophylls, and sometimes also on the outer surface of the involucre. Involucre lobes are initially yellowish cream (similar to the glands), but in some cyathia they acquire red tint with age. The gynoecium also becomes reddish after anthesis in some cases. 3. It is evident that the species possesses male cyathia, which develop in the same inflorescences with the hermaphrodite cyathia (Fig. 1 B, F, G). As far as the hermaphrodite cyathia of E. bokorensis (Fig. 1 D, E) are protogynous (which is typical for the genus: Narbona et al. 2002), the absence of an externally visible pistillate flower at the phase of anthesis of the staminate flowers would indicate that the pistillate flower is non-functional or completely absent in a cyathium. The male cyathia are also visible in Fig. 5 C, D of the protologue (Toyama et al. 2016). The presence of male cyathia in E. bokorensis is consistent with the findings of Narbona et al. (2002) who demonstrated such functional andromonoecy to be common in Euphorbia Linnaeus (1753: 450) and especially in its perennial species. According to our preliminary observations, a vestigial pistillate flower is commonly present in male cyathia of E. bokorensis. 4. Re-examination of the type material allowed to conclude that Toyama et al. (2016) have only examined male cyathia of E. bokorensis. Here, we provide for the first time illustrations (Fig. 1 B, C, D, E) and description of a functional (normally developed) pistillate flower of this species. Pistillate flower glabrous, perianthless, green and sometimes becoming reddish with age; pedicel ca. 1 mm long (ovary placed just above the involucre glands or partly hidden in the involucre during anthesis); pedicel apically broadened to form a tiny collar at base of gynoecium; ovary globose, ca. 1 mm long and in diameter, longitudinally slightly 6 - ridged, 3 - locular; stylar column ca. 0.3 – 0.5 mm long; styles 3, ca. 0.5 – 0.8 mm long, bilobed almost to base; each style branch bent on abaxial side (facing the involucre of cyathium), apically bearing nearly globose papillate stigma.	en	Nuraliev, Maxim S., Toyama, Hironori, Hu, Chi-Ming, Luo, Shi-Xiao, Lyskov, Dmitry F., Kuznetsov, Andrey N., Kuznetsova, Svetlana P., Quang, Bui Hong, Binh, Tran Duc, Hoan, Duong Thi (2022): Three new national records from Kon Chu Rang Nature Reserve, Vietnam: Euphorbia bokorensis, Glochidion geoffrayi and Lysimachia nutantiflora.

As follows from the key provided by Gagnepain & Beille (1927), Glochidion geoffrayi is distinct from its morphologically similar congeners mainly by the hairy stylar column (Fig. 3 E – G). Glochidion geoffrayi differs from G. anamiticum (Kuntze 1891: 601) Kuntze ex Merrill (1936: 195) (including G. annamense Beille 1927: 627), which also possesses a hairy stylar column, by longer styles with respect to the stylar column: the style / stylar column ratio is more than 2 in G. geoffrayi (Gagnepain & Beille 1927: Fig. 74 - 14) and about 1.5 – 2 in G. anamiticum (Gagnepain & Beille 1927: Fig. 74 - 19, Yao et al. 2018: Fig. 2 A).	en	Nuraliev, Maxim S., Toyama, Hironori, Hu, Chi-Ming, Luo, Shi-Xiao, Lyskov, Dmitry F., Kuznetsov, Andrey N., Kuznetsova, Svetlana P., Quang, Bui Hong, Binh, Tran Duc, Hoan, Duong Thi (2022): Three new national records from Kon Chu Rang Nature Reserve, Vietnam: Euphorbia bokorensis, Glochidion geoffrayi and Lysimachia nutantiflora.

038E851F47195073EEE7627CFB0D0B18.taxon	discussion	Notes. Lysimachia nutantiflora is described as having an elongate several- to many-flowered terminal raceme, which is an important character for identification of this species (Hu & Kelso 1996). However, the flower-subtending bracts of L. nutantiflora are leaf-like, with the lower bracts differing from the leaves only in being twice smaller (sometimes even insignificantly smaller, as seen in the Vietnamese specimen). Thus, L. nutantiflora shows an intermediate morphology between a terminal raceme and solitary flowers in axils of the upper leaves.	en	Nuraliev, Maxim S., Toyama, Hironori, Hu, Chi-Ming, Luo, Shi-Xiao, Lyskov, Dmitry F., Kuznetsov, Andrey N., Kuznetsova, Svetlana P., Quang, Bui Hong, Binh, Tran Duc, Hoan, Duong Thi (2022): Three new national records from Kon Chu Rang Nature Reserve, Vietnam: Euphorbia bokorensis, Glochidion geoffrayi and Lysimachia nutantiflora.
