Yunnan harbors 195 </span><span lang="en-GB"><em>Carex</em></span><span lang="en-GB"> species, encompassing 22 new records and recently published taxa. Prof. Wu Zhengyi’s classification of Chinese seed plants into 15 area-types, widely accepted by phytogeographers for decades, serves as our framework. Type 1 families and genera, deemed cosmopolitan, are often excluded in floristic statistics due to their perceived lack of floristic indication. We analyzed the floristic characteristics of Yunnan’s </span><span lang="en-GB"><em>Carex</em></span><span lang="en-GB">, particularly representative Type 1 genera, reveals a predominantly temperate nature rather than tropical. The substantial presence of species affiliated with the Sino-Himalaya area-subtype indicates a strong association with the Sino-Himalayan Forest Subkingdom. As a globally distributed genus, </span><span lang="en-GB"><em>Carex</em></span><span lang="en-GB"> holds significant floristic indication at the species level. This study shows the significant value of this cosmopolitan genus in floristic research. For accurate elucidation of floristic characteristics, it is imperative to conduct species-level analyses of Cosmopolitan Area-Type genera when studying the flora of a specific floristic region.</span></span></span></span></p> YUAN-YUAN LI, LI-QIONG JIANG, LI CHEN, YONG CHAI, HONG-JIN DONG, HUA PENG Copyright (c) 2024 https://phytotaxa.mapress.com/pt/article/view/phytotaxa.665.2.3 Thu, 19 Sep 2024 00:00:00 +1200 <strong>Three new small-flowered <em>Magnolia</em> species (<em>Magnolia</em><em> </em>sect.<em> </em><em>Magnolia</em>, Magnoliaceae) from Guatemala</strong> https://phytotaxa.mapress.com/pt/article/view/phytotaxa.665.2.4 <p align="justify"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;"><span lang="en-GB">Three new endemic species of </span><span lang="en-GB"><em>Magnolia</em></span><span lang="en-GB"> from Guatemalan cloud forest are described and illustrated: </span><span lang="en-GB"><em>Magnolia emilceana</em></span><span lang="en-GB"> from Baja Verapaz Department, </span><span lang="en-GB"><em>M. harnpariphana</em></span><span lang="en-GB"> from Baja and Alta Verapaz Departments and</span><span lang="en-GB"><em> M. juliana</em></span><span lang="en-GB"> from Alta Verapaz Department.

This study represents the first comprehensive investigation into the morphology, anatomy, pollen and seed micromorphology, and chromosome characteristics of <em>O. argaea</em>. The previous description of the species has been expanded and modified. The pith of the root is covered with xylem tissue. In the stem cross-section, the protective tissue is periderm in the woody part and epiderm in the herbaceous part. The leaflets are amphistomatic and equifacial. The pollen grains are radially symmetric, isopolar, tricolpate, with prolate shape and reticulate-microreticulate ornamentation. The seeds are reniform, yellowish-brown, suboblate, and exhibit rugulate surface ornamentation. The number of somatic chromosomes in <em>O. argaea</em> is 2<em>n </em>= 14<em>.</em> The karyotype formula of this species consists of seven median chromosomes.</span></span></span></p> BAYRAM ATASAGUN, AHMET AKSOY, ESRA MARTİN Copyright (c) 2024 Phytotaxa https://phytotaxa.mapress.com/pt/article/view/phytotaxa.665.2.5 Thu, 19 Sep 2024 00:00:00 +1200 <strong>Addition to the genus <em>Harmajaea</em> (Agaricales, Pseudoclitocybaceae): a new and a known species from China</strong> https://phytotaxa.mapress.com/pt/article/view/phytotaxa.665.2.6 <p align="justify"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;"><span lang="en-GB">A new species, </span><span lang="en-GB"><em>Harmajaea xizangense</em></span><span lang="en-GB">, discovered in Tibet, China, is illustrated and described based on morphological and molecular data.
