This academic activity was the result of a collaboration between the BSI-SHRC and Forest &amp; Environment Dept., Government of Sikkim. The course was attended by seventy-one people from across India.</p> Kanchi N.

Therefore, non-morphological identification methods are instrumental in differentiating species and their interspecific hybrids. Primers were developed from the ITS and ETS regions for 4 sympatric species present in North America to assess their utility in the identification of species, and natural and simulated hybrids by multiplex PCR amplification and gel electrophoresis. We found that these multiplexed PCRs were highly accurate in the identification of the 4 study species as well as natural hybrids. Simulated hybrids (in vitro combinations of total DNA extracts) to confirm co-amplification in multiplexed PCR also showed high rates of amplification but were sensitive to dosage effects of parental DNA. Overall, this study demonstrates a promising method to cheaply and quickly identify large numbers of individuals of most species of <em>Triodanis</em> and could be applied to more species, given sufficient differentiation in target DNA locus and species-specific constancy of targeted variation.</p> Alyssa Wu Zhan Jolie E.

Here we review the morphological variation in the context of regional phylogenetic data from two independent datasets to recircumscribe the taxa. We show the complex to consist of three taxa, <em>P. crocata, P. dimorphophylla</em> var. <em>dimorphophylla,</em> and <strong>P. intermedia,</strong> a new combination for a little-recognized taxon previously treated as a variety of <em>P. dimorphophylla.</em></p> Charles F.

Clark of the Gesneriaceae (tribe: Gesnerieae, subtribe: Columneinae). The new species is distinguished by the combination of isophyllous leaf pairs, fimbriate calyx lobe margins, and a deeply bilabiate corolla that is dark purple with yellow corolla lobe margins. The new species is endemic to the Cordillera del Cóndor in southern Ecuador where it was collected from the wild in 2005 and brought into cultivation by Ecuagenera and has since been distributed by horticulturists throughout several countries.</p> John L.

Haug. 2018. <em>Sedges and rushes of Minnesota: The complete guide to species identification;</em> P.E. Rothrock. 2021. <em>Sedges of Indiana and the adjacent states—the Carex species</em>-(Vol. II); J. Ogle, T. Witsell, and J. Gentry. 2022. <em>Trees, shrubs, and vines of Arkansas.</em> Reviews of each are provided by McKenzie (2009, 2020, 2021, 2022). Any book on the genus <em>Carex</em> that includes stellar reviews and/or input from three of most renowned experts on the genus: A. Reznicek, A. Hipp, and P. Rothrock has to be good, and this field guide will not disappoint!</p> Paul M.

In 2024, a large, naturalized population of <em>P. fortunei</em> was discovered in highly disturbed riparian habitat adjacent to a large residential area, within the city of Magnolia. Plants were sterile but aggressively establishing via rhizomatous offsets. The precise origin of the naturalized plants is unknown, although establishment from once cultivated plants of the species is suspected, as a residence adjacent to the location of the naturalized plants had a large colony of <em>P. fortunei</em> that had spread throughout much of the property.</p> Brett E.

Unwinding the Story of Plant Spirals, From Leonardo da Vinci to Now https://journals.brit.org/jbrit/article/view/1410 <p><em>Do Plants Know Math?</em> takes you down through the centuries to explore how great minds have been captivated and mystified by Fibonacci patterns in nature. It presents a powerful new geometrical solution, little known outside of scientific circles, that sheds light on why regular and irregular spiral patterns occur. Along the way, the book discusses related plant geometries such as fractals and the fascinating way that leaves are folded inside of buds. Your neurons will crackle as you begin to see the connections. The book will inspire you to look at botanical patterns—and the natural world itself—with new eyes.</p> Barney Lipscomb Copyright (c) 2025 Botanical Research Institute of Texas https://creativecommons.org/licenses/by-nc-nd/4.0/ 2025-06-23 2025-06-23 19 2 132 132 10.17348/jbrit.v19.i2.1410 Range Plants of North Central Texas: A Land User’s Guide to Their Identification, Value and Management https://journals.brit.org/jbrit/article/view/1411 <p>Now in its 6th printing (2025), <em>Range Plants of North Central Texas: A Land User’s Guide to Their Identification, Value and Management</em> provides several photos, 1,450 in total, for each of the 324 plants (160 forbs, 59 grasses, and 105 woodies) with emphasis on leaves, flowers, fruits, and other details to aid in identification. The text is predominately written for the layman plant enthusiast with a minimum of technical, botanical terms. Each plant is discussed with identification tips, value, and management. The sections on the value of the plants will be of most interest to many readers because this information is harder to find from other sources.</p> Barney Lipscomb Copyright (c) 2025 Botanical Research Institute of Texas https://creativecommons.org/licenses/by-nc-nd/4.0/ 2025-06-23 2025-06-23 19 2 146 146 Field Guide to the Grasses of Oregon and Washington. Second Edition https://journals.brit.org/jbrit/article/view/1412 <p><em>Field Guide to Grasses of Oregon and Washington</em> (1<sup>st</sup> ed., 1999) was reviewed in J. Bot. Res. Inst. Texas 14(1), 2020. The reviewer noted that the Field Guide “is a comprehensive source of information on all 101 genera and 376 species, subspecies, and varieties of grasses known to occur in the natural environment of Oregon and Washington.” The second edition treats 394 species, 18 additional species more than the first edition. The new edition also includes “updated names, new keys, and improved photographs and maps.”The labeled macrophotographs illustrated beautifully the hard-to-see diagnostic features, critical for identification.</p> Barney Lipscomb Copyright (c) 2025 Botanical Research Institute of Texas https://creativecommons.org/licenses/by-nc-nd/4.0/ 2025-06-23 2025-06-23 19 2 154 154 10.17348/jbrit.v19.i2.1412 Botany of the 1860 Chadbourne Expedition from Williams and Bowdoin colleges to Labrador and Greenland. Part 1: Greenland https://journals.brit.org/jbrit/article/view/1403 <p>In 1860 Paul A. Chadbourne, Professor at both Williams College and Bowdoin College, arranged a scientific expedition to Labrador and Greenland. Traveling by schooner, the party of nineteen comprised nine students and two recent graduates from Williams, three from Bowdoin, two from Harvard, and three others, plus the Professor and the ship’s owner and captain, Charles E. Ranlett of Thomaston, Maine. They departed Thomaston on 27 June, left seven members of the party on Caribou Island in the Straits of Belle Isle, and proceeded toward West Greenland, hoping to make landfall at Paamiut (Frederickshåb). Instead, they were forced northward by storm-driven pack ice ca. 250 miles before making landfall near Maniitsoq (Sukkertoppen), where they collected plant and animal specimens 19–30 July. They then sailed south ca. 100 miles to the capital, Nuuk (Godthåb), where they collected additional plant specimens and purchased or were gifted various other natural history and cultural materials. Leaving Nuuk on 14 August, they returned to Caribou Island, boarded the students who had made similar collections there, and returned to Maine on 11 September.</p> <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Expedition’s Greenland plant collections, comprising more than 220 specimens and representing 93 taxa, are in two main two groups. The smaller collection, with 64 specimens, was purchased from Professor Chadbourne and donated anonymously to Bowdoin College in 1881 and is now at the Pringle Herbarium. The other, larger, set of more than 175 specimens collected by Williams ’61 student William P. Alcott was deposited at Williams College and is currently housed at Muskingum University in New Concord, Ohio. A few additional Alcott specimens, apparently sent to others for identification, are in other U.S. herbaria. These sets of collections and images were studied, identified, and revised as necessary and are published here for the first time. The Chadbourne Expedition specimens constitute the earliest large, systematically collected set of herbarium records for central West Greenland and should be considered historically significant.</p> Arthur V.
