**Taxonomic implications of anatomical characteristics of the genus Tulipa (Liliaceae) in Turkey and their place in the historical subgeneric classifications**

2022-07-01T11:31:53+12:00

This paper comprehensively discusses anatomical features of the genus Tulipa (Liliaceae) in Turkey. These are compared with the current subgeneric classification. 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 (mm²), 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 Tulipa 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 & Zonneveld and Christenhusz et al. including three subgenera, Eriostemones, Tulipa and Clusianae, but subgenus Orithyia was not included in this study because it is absent from Turkey. Subgenus Eriostemones is divided into two sections, Sylvestres and Saxatiles, following treatments by Baker and Eker et al. In subgenus Tulipa, although morphometric analyses partially supported the taxonomic grouping previously proposed as three separate sections, Tulipa, Tulipanum and Eichleres, it also clearly indicates that considering them as a single section (Tulipa) is perhaps a better option.

Miliusa agasthyamalana (Annonaceae), a new species from the Western Ghats, India is described and illustrated. The new species is morphologically similar to M.paithalmalayana and M. wightiana. Detailed notes on the species along with its color photographs and illustrations are provided.

**Morphological and molecular identification of Ellipsoidisporodochium gen. nov. (Tubakiaceae, Diaporthales) in Hainan Province, China**

2022-07-01T11:31:56+12:00

During a survey of microfungi on symptomatic leaves from Photinia serratifolia (Desfontaines) Kalkman, an interesting species of asexual ascomycetes were found. 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 (tef1), part of the beta-tubulin gene region (tub2), and partial RNA polymerase II second largest subunit (rpb2), in conjunction with morphological characteristics, we describe a new genus of Tubakiaceae, Ellipsoidisporodochium gen. nov. (type species: Ellipsoidisporodochium photiniae sp. nov.). The genus has fusoid to ampulliform sporodochia and obovoid to ellipsoid conidia. Their relatedness to allied taxa are also annotated and discussed.

Tupistra thangii (Asparagaceae), a new species from southern Vietnam

2022-07-01T11:31:58+12:00

Tupistra thangii, a new species from Lam Dong Province, southern Vietnam, is described and illustrated. It is most similar to T. clarkei 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 T. natmataungensis from western Myanmar. Notes on the phenology, habitat, distribution and taxonomic relationships to several similar species are also provided.
