Although the genus Lophopogon comprises only two distinct species, their identification has always been bewildering in some of the available grass literature in India. This confusion mainly stems from the tendency of Indian botanists to utilize weak key characters to differentiate the species. We have discussed both the variable as well as distinguishing features of the Lophopogon species and revised the key to make it more efficient. Upon a thorough morphological study of the recently described L. prasannae, we have concluded that it is but a variable form of an obscure species L. kingii. Therefore, we now consider it a new heterotypic synonym of the latter. While re-evaluating the previously misidentified specimens of Lophopogon, we have established two new distributional records of L. kingii for the states of Andhra Pradesh and Karnataka, South India. In L. kingii a characteristic whitish indumentum is observed, which is confined to the base of the plant and is not observed in any of the variable forms of L. tridentatus. Based on this character, we have restructured and simplified the identification key for easy and accurate species delimitation. We have also provided a brief discussion on the phenotypic variability of both the species, along with photo plates to facilitate identification and showcase a variability spectrum in plant habit. Distribution of L. kingii is plotted on the map based on the available specimens at BSI, BSID, CAL and K herbaria.
虽然 Lophopogon 属只有两个不同的种，但在印度现有的一些草类文献中，它们的识别一直令人困惑。这种困惑主要源于印度植物学家倾向于利用较弱的关键特征来区分物种。我们讨论了 Lophopogon 物种的易变特征和区分特征，并修订了检索表，使其更加有效。在对最近描述的 L. prasannae 进行彻底的形态学研究后，我们得出结论，它只是一个不知名的种 L. kingii 的变异形式。因此，我们现在认为它是后者的一个新的异形异名。在重新评估之前被误认的 Lophopogon 标本时，我们为南印度的安得拉邦和卡纳塔克邦建立了两个新的 L. kingii 分布记录。在 L. kingii 身上，我们观察到了一种特有的带白色毛被，这种毛被仅限于植株基部，在 L. tridentatus 的任何变异形式中都没有观察到。根据这一特征，我们调整并简化了识别关键词，以方便准确地划分物种。我们还对这两个物种的表型变异进行了简要讨论，并附有照片，以方便识别和展示植物习性的变异谱。根据 BSI、BSID、CAL 和 K 标本馆的现有标本，在地图上绘制了 L. kingii 的分布图。

A revision of the genus Oreocomopsis was carried out based on the study of morphological, anatomical and molecular phylogenetic data based on ITS nrDNA sequences, of which the scope and composition were specified. The identity of O. xizangensis with the previously described O. dochenensis is shown; on the contrary, O. aromatica is singled out as an independent taxon. Ostericum scaberulum var. longiinvolucellatum is included in the genus Oreocomopsis as an independent species. Taxonomic features of the genus and differences from related genera are analysed. The species Oreocomopsis stelliphora has been assigned to the new genus Oreocomoides. The new genus Oreocomoides markedly differs from Oreocomopsis in many morphological characters, such as heterophyllous leaf blades: bipinnate in lower part and narrow-linear pinnate in upper part; bracts polymorphic, linear or pinnate with linear lobules; calyx teeth developed; petals with oval plate, at base with well-developed claw; pedicels rounded; mericarps ribs similar, narrowly-winged, slightly widened at the base.

Euphorbia is one of the largest genera of flowering plants, and Mexico is one of the primary centers of diversification. Much work remains before a thorough understanding of the Mexican species is reached, and the present contribution aims to unambiguously allow the application of 14 names by clarifying their types. Some of these are distributed outside of Mexico, including Canada, the United States, Central America, South America, and the Antilles. Lectotypes of the following names are designated: E. biformis, E. boliviana, E. elastica, E. gumaroi, E. lancifolia, E. luciismithii, E. macropus, E. mendezii, E. potosina, E. subreniformis, and E. umbellulata. In the absence of original material, neotypes are selected for the following names: E. nudiflora, E. tanquahuete, and E. vermiculata. All the names are currently accepted, except for E. elastica (=E. tanquahuete) and E. biformis (=E. macropus).
大戟属是有花植物中最大的属之一，而墨西哥是其多样化的主要中心之一。在彻底了解墨西哥物种之前，还有许多工作要做，本报告旨在通过澄清其类型，明确 14 个名称的应用。其中一些分布在墨西哥以外的地区，包括加拿大、美国、中美洲、南美洲和安的列斯群岛。指定了以下名称的分型：E.biformis、E. boliviana、E. elastica、E. gumaroi、E. lancifolia、E. luciismithii、E. macropus、E. mendezii、E. potosina、E. subreniformis 和 E. umbellulata。在没有原始材料的情况下，为以下名称选择了新原型：E.nudiflora、E.tanquahuete 和 E.vermiculata。除了 E. elastica（=E. tanquahuete）和 E. biformis（=E. macropus）之外，所有名称目前都已被接受。

Coniella has a wide distribution as a plant pathogen in Eucalyptus species. Here we report a leaf spot disease caused by Coniella eucalyptorum on Eucalyptus camaldulensis in Sri Lanka. The pathogen was isolated from symptomatic leaf samples of E. camaldulensis plants from Polonnaruwa District in Sri Lanka. The isolated fungus was identified as C. eucalyptorum based on morphological characteristics and multi-gene phylogenetic analysis of combined sequences of the internal transcribed spacer region (ITS), the partial translation elongation factor 1-α gene (tef1-α), and large subunit of nuclear ribosomal RNA (LSU). The pathogenicity test was performed to confirm its pathogenicity to the host, which produced symptoms similar to those observed in the field. This is the first report of C. eucalyptorum associated with Eucalyptus plantations in Sri Lanka. This finding is important to expand the knowledge of plant pathogen diversity in Eucalyptus species and other economically important crops in Sri Lanka.

In this study, Tulipa sarvestanica (Liliaceae) is described and illustrated as a new species from south-western Iran. Tulipa sarvestanica differs from similar T. systola by having a smaller bulb with arachnoid bristles, smaller fruit (capsule) size, lower black blotch area at the base of the perianth, yellow anther versus purple anther in T.systola. The detailed description, diagnostic features, geographical distribution, habitat, original photographs, phenology, etymology, genome size, conservation status, and related species are presented in this study. Based on the IUCN criteria, the conservation status of Tulipa sarvestanica is classified as endangered (EN) species.

Aspidistra longzhouensis, a new species of Asparagaceae from Guangxi, southern China, is described and illustrated here. It is morphologically similar to A. patentiloba Y. Wan & X. H. Lu, but the new species is differentiated by its smaller leaf, flower completely pure white, stigma upper surface glabrous and with 4 radial lines, bifurcate lines at center. The new species is currently known only from the Karst areas in southwest Guangxi. Colour plates of the similar species are provided for comparison.

Allium beypazariense, a newly discovered species from the A. section Codonoprasum, is described and illustrated in this study. The species is endemic to middle Anatolia, Beypazarı and Çayırhan districts in Ankara in Türkiye. This research provides a comprehensive examination of the species, including its morphology, phenology, leaf anatomy, seed testa micromorphology, and conservation status. A comprehensive description of this species is provided, including detailed photographs and illustration, geographical distribution map, habitat and ecology. Furthermore, the taxonomic relationships between Allium beypazariense and its closest relatives, A. opacum is thoroughly explored and discussed. The new species can be easily distinguished from the close species by its mucronate tepal apex, sessile ovary, different anther colour, and thick scape.
