These are compared with the current subgeneric classification.&nbsp; &nbsp;Anatomical structures, including transverse sections of the root, stem (scape) and leaf, and surface sections of the leaves are illustrated based on the 420 preparations obtained from 42 OTUs (populations) belonging to 18 taxa. Densities of stomata and epidermis cells per unit leaf area (mm<sup>2</sup>), stomatal index and ratio of stomata index on the leaf surfaces were also calculated. Cluster and principal component analyses (PCA) were employed, and all results were compared at the population level. In this anatomical study, some significant differences were found among <em>Tulipa</em> taxa, especially at the infrageneric and interspecific levels. The results of anatomical investigations are consistent with published results of previous morphological and molecular analyses. The results of cluster analysis and PCA support the classifications of Veldkamp &amp; Zonneveld and Christenhusz <em>et al.</em> including three subgenera, <em>Eriostemones, Tulipa </em>and <em>Clusianae</em>, but subgenus <em>Orithyia</em> was not included in this study because it is absent from Turkey. Subgenus <em>Eriostemones</em> is divided into two sections, <em>Sylvestres</em> and <em>Saxatiles</em>, following treatments by Baker and Eker <em>et al</em>. In subgenus <em>Tulipa</em>, although morphometric analyses partially supported the taxonomic grouping previously proposed as three separate sections, <em>Tulipa</em>, <em>Tulipanum </em>and <em>Eichleres</em>, it also clearly indicates that considering them as a single section (<em>Tulipa</em>) is perhaps a better option.</p> İSMAİL EKER EZGİ TANIŞ Copyright (c) 2022 Phytotaxa 2022-07-01 2022-07-01 552 4 221 251 10.11646/phytotaxa.552.4.1 <p><strong><em>Miliusa agasthyamalana</em> (Annonaceae), a new species from southern Western Ghats, India</strong></p> <p><em>Miliusa agasthyamalana</em> (Annonaceae), a new species from the Western Ghats, India is described and illustrated.

Based on multilocus phylogenies from a combined dataset of genes encoding internal transcribed spacer (ITS), large subunit of ribosomal RNA (LSU), translation elongation factor 1 alpha (<em>tef1</em>), part of the beta-tubulin gene region (<em>tub2</em>), and partial RNA polymerase II second largest subunit (<em>rpb2</em>), in conjunction with morphological characteristics, we describe a new genus of Tubakiaceae, <em>Ellipsoidisporodochium gen. nov.</em> (type species: <em>Ellipsoidisporodochium photiniae</em> <em>sp. nov.</em>). The genus has fusoid to ampulliform sporodochia and obovoid to ellipsoid conidia. Their relatedness to allied taxa are also annotated and discussed.</p> SHU-BIN LIU ZHAO-XUE ZHANG RONG-YU LIU TAI-CHANG MU XIU-GUO ZHANG ZHUANG LI JI-WEN XIA Copyright (c) 2022 Phytotaxa 2022-07-01 2022-07-01 552 4 259 266 10.11646/phytotaxa.552.4.3 <p><strong><em>Tupistra thangii</em> (Asparagaceae), a new species from southern Vietnam</strong></p> <p><em>Tupistra thangii</em>, a new species from Lam Dong Province, southern Vietnam, is described and illustrated. It is most similar to <em>T. clarkei</em> from eastern Nepal and northeastern India, but differs mainly in its broader leaves, upright or ascending spike, smaller flowers, laterally strongly revolute perianth lobes, stamens adnate to the subbasal portion of the perianth lobes, and whitish stigma. It also shares some key traits (e.g. internally white-striped, dark purple perianth tube) with <em>T. natmataungensis</em> from western Myanmar. Notes on the phenology, habitat, distribution and taxonomic relationships to several similar species are also provided.</p> DANH DUC NGUYEN VAN CANH NGUYEN NORIYUKI TANAKA Copyright (c) 2022 Phytotaxa 2022-07-01 2022-07-01 552 4 267 273 10.11646/phytotaxa.552.4.4 <p><strong>Lectotypification of the name <em>Dipcadi erythraeum</em> Webb &amp; Berthel.
