Revisión taxonómica del género Anastrophyllum (Spruce) Steph. (Marchantiophyta, Jungermanniaceae) para Colombia
No full textEn el estudio taxonómico del género Anastrophyllum para Colombia se registran seis especies agrupadas en tres subgéneros: A. auritum (Lehm.) Steph., A. nigrescens (Mitt.) Steph., A. piligerum (Reinw., Blume and Nees) Steph. (subg. Anastrophyllum), A. austroamericanum Váňa (subg. Crossocalyx), A. stellatum R.M. Schust. y A. tubulosum (Nees) Grolle (subg. Schizophyllum). El género Anastrophyllum se caracteriza por la pigmentación pardo-rojiza, rojo-negruzca, ocasionalmente verde; tallos con corteza y médula diferenciadas; ramificación lateral tipo Frullania, lateral tipo Plagiochila y ventral tipo Bazzania; hojas bífidas, cóncavas, asimétricas, margen entera; células con trígonos pequeños a conspicuos. Dioicas; perianto emergente, cilíndrico, plegado desde la base o solamente en la parte distal, con la boca hialina. Para cada una de las especies se proporciona una descripción detallada, ilustraciones, mapas de distribución y una clave donde se destacan principalmente caracteres del gametofito. Se evaluó la importancia diagnóstica de los caracteres morfo-anatómicos de tallo, hoja, células, perianto y cápsula. El análisis filogenético de los caracteres, a pesar de no mostrar como grupos monofiléticos a cada uno de los subgéneros, es posible diferenciarlos morfológicamente. / Abstract. Six species in three subgenera are recognized in the taxonomic study of the genus Anastrophyllum for Colombia: A. auritum (Lehm.) Steph., A. nigrescens (Mitt.) Steph., A. piligerum (Reinw., Blume and Nees) Steph. (subg. Anastrophyllum), A. austroamericanum Váňa (subg. Crossocalyx), A. stellatum R.M. Schust. and A. tubulosum (Nees) Grolle (subg. Schizophyllum). The genus Anastrophyllum is characterized by a reddish-brown to red-black, occasionally green, pigmentation; stems with a distinctive cortex and medulla; terminal branching of the Frullania- and Plagiochila-type and, ventral-intercalary branching of the Bazzania-type; leaves always bifid, concave, asymmetric; cells with inconspicuous or large to coarsely nodose trigones. Dioecious; perianth emergent, cylindrical, plicate, with a hyaline mouth. A key to species, based on gametophytic characters is provided and descriptions, illustrations and distribution maps are given for each species. The importance of diagnostic morpho-anatomical characters of stem, leaf cells, perianth and capsule are evaluated. Grouping of species into the three subgenera wasn´t obtained by the phylogenetic analysis; however, these subgenera can be to separated by morphological characters.Maestrí
You Are Here triptych
No full text"You Are Here" is a digital art piece printed on canvas by artist Steph Littlebird. The piece depicts plants and animals native to the land that Pacific University’s Forest Grove and Hillsboro campuses are situated; the land of the Tualatin Kalapuyas, or Atfalati, now part of the Confederated Tribes of Grand Ronde.
Littlebird's statement on "You Are Here": "This design combines a landscape and topographical view of the land Pacific University is situated on. Overlapping depictions of Indigenous plants and animals with maps of the local river systems remind viewers of where they are, focusing their awareness on the present with a mindful message 'You are here.'"
"You Are Here" was commissioned by the University Cultural Collections Committee in 2024 for the entryway of Les AuCoin Hall. Created by Steph Littlebird, an artist, author, curator and enrolled member of Oregon’s Grand Ronde Confederated Tribes. Steph earned her B.F.A. in Painting and Printmaking from the Pacific Northwest College of Art (PNCA) in Portland, Oregon, she currently lives and works in Las Vegas.
Littlebird is known for her vibrant graphic imagery that combines traditional styles of her Indigenous ancestors with contemporary illustration aesthetics. Her work often examines issues related to Native identity, cultural resilience, and responsible land stewardship

The complete chloroplast genome of Scapania ampliata Steph., 1897 (Scapaniaceae, Jungermanniales)
No full textWe completed chloroplast genome of Scapania ampliata Steph., presenting distinct morphological features including yellowish brown, one-celled gemmae, and decurrent dorsal lobe. It is 118,026 bp long and has four subregions: 80,850 bp of large single copy (LSC) and 19,436 bp of small single copy (SSC) regions are separated by 8,870 bp of inverted repeat (IR) regions including 130 genes (86 protein-coding genes, 8 ribosomal RNAs, and 36 transfer RNAs). The overall guanine cytosine (GC) content is 34.0% and those in the LSC, SSC, and IR regions are 31.9%, 31.0%, and 46.3%, respectively. Phylogenetic trees show S. ampliata is clustered with Scapania ciliata
Résultats taxonomiques de l´éxpédition Bryotrop au Zaire et Rwanda : 30., bryophytes épiphylles (récoltes de E. Fischer)
No full textThe author provides an annotated list of epiphyllous bryophytes collected by Dr E. Fischer in Kivu and Rwanda. Most of them belong to the Lejeuneaceae, but some other hepatics and mosses are also represented. A total of 101 hepatics and 17 mosses are reported. In this very important material, 13 new species and 2 varieties for science or for Africa were found: Cololejeunea cardiocapioides , C. fischerii , C. heterolobula , C. kahuziensis , C. lobulolineata , C. pseudo-obliqua , C. pseudo-pusilla , C. sphaerocarpa , C. tenui-parietata , C. tribracteata , Diplasiolejeunea cyanguguensis , C. gradsteinii , Harpalejeunea fischerii , Cololejeunea harrisii Pócs var. magna, and Drepanolejeunea symoensii (Vanden Berghen) Grolle var. minor. Some observations and ideas are given for Cheilolejeunea, in preparation for a future monograph of the genus in Africa and the Mascareno-Malagassy region. Drepanolejeunea , based on the author’s analysis is relatively depauperate in Africa (where some of the species are South East Asian taxa). The study of the genus was complicated because of the use of perianth characters in taxonomical delimitation. However, perianths are seldom encountered and are very variable. In Cololejeunea , the author builds on his earlier works on the genus in different regions and particularly in Madagascar. Some taxa were insufficiently defined and the author tries to separate the different species. The application of subgenera in Cololejeunea remains difficult. For example, C. platyneura is a member of the subgenus Taeniolejeunea, but may be confused with members of subg. Cololejeunea
'The C Words': Clitorises, childhood and challenging compulsory heterosexuality discourses with pre-service primary teachers
No full textThis paper reports on accidental ethnographic research. It arose unexpectedly out of the
everyday teaching of first-year pre-service primary teachers at an Australian university.
Via narrative, self-reflexivity, and student responses, we explore the interwoven
workings of heteronormative, gendernormative and misogynist discourses when a
chapter from Queering Elementary Education in the Course Reader created
controversy, moral panic and resistance among students. The paper then charts the
implementation of various strategies and interventions by the three authors of the
paper: Greg, the lecturer; Maria, the Reading’s author; and Steph, the Reading’s
protagonist. While outlining the subsequent shifts in student responses and discourses,
we also problematise particular aspects of the processes of intervention where they still
point to the insidious power and overarching framework of heteronormativity and
gendernormativity that require ongoing challenges
Studies in the genus Riccia (Marchantiales) from southern Africa. 9. R. nigrella and the status of R. capensis
No full textR. nigrella DC. (Lamarck & De Candolle 1815), with which R. capensis auct. non Steph.: S. Amell (1952, 1963), is conspecific, is now also recognized from southern Africa. The thallus is brown marginally and dorsally and has shiny black scales with smooth margins at which coloured and hyaline cells alternate irregularly. Arnell's (1961) records of R. capensis Steph. from the Canary Islands are to be regarded as erroneous. R. capensis Steph. (Stephani in Brunnthaler 1913) is now placed in synonymy under R. limbata Bisch

Results of a botanical expedition to mount Roraima, Guyana. I. Bryophytes
No full textA bryological inventory of the Upper Mazaruni District, Guyana (former British Guiana) yielded almost three hundred species, including 2 genera and 11 species new to science and 130 species new to the Guianas. The densely forested and very humid north slope of Mount Roraima (500-2300 m.) proved to be the richest area for bryophytes and most of the novelties were found there. The present paper provides an enumeration of the species collected with a brief characterization of their habitat. The following species are described as new: Haesselia acuminata Gradst., Plagiochila gymnocalyx Inoue, Radula gradsteinii Yamada, Radula guyanensis Yamada, Radula mazarunensis Yamada and Stenorrhipis grollei Gradst. Anastrophyllum subg. Vanaea Inoue & Gradst. from Mount Roraima is elevated to generic rank
