Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Myoxanthus bolivianus Karremans, I. Jimenez & M. Zarate
No full text4. Myoxanthus bolivianus Karremans, I.Jiménez & M.Zárate in Karremans & Vieira-Uribe (2020: 202). TYPE: BOLIVIA. Cochabamba: Prov. Carrasco, Parque Nacional Carrasco, 20 km entrando de Monte Punco a Pajcha, cerca al túnel Hidroeléctrica Ivirizu, 17º27’16”S, 65º16’33”W, 2100 m, bosque montano pluvial, ladera empinada, 8 Jan 2019, Zárate 6551 & Bayá (holotype: BOLV!; isotype: LPB!). Distribution: — Bolivia. Notes:— This recently described species has the proliferous habit and flowers similar to M. epibator, from which it differs in the longer sepals (5.5–6.0) with slender tails (vs. 4.5 mm and clavate), lip yellowish suffused with purple (vs. lip dark purple) with a prominent erect callus at the base (vs. lacking a tall basal callus).Published as part of Rojas-Alvarado, Gustavo, Blanco, Mario A. & Karremans, Adam P., 2021, A taxonomic synopsis and morphological characterization of Myoxanthus (Orchidaceae: Pleurothallidinae), pp. 211-258 in Phytotaxa 507 (3) on page 230, DOI: 10.11646/phytotaxa.507.3.1, http://zenodo.org/record/542572
Myoxanthus dasyllis Luer & Hirtz 1992
No full text12. Myoxanthus dasyllis Luer & Hirtz (1992: 28‒29) TYPE:— ECUADOR. Morona Santiago: Cordillera del Cutucú, between Mendez and Morona, 950 m, 17 Jan 1989, Luer et al. 13971 (holotype: MO!). Distribution: — Ecuador. Notes:— According to Luer & Hirtz (1992), the flowers of this species are distinguished by their densely redspiculate floral bracts, ovary and sepals that are borne by short peduncles (actually pseudopeduncles) usually less than three millimeters long, petals thickened and microscopically erose or cellular-capitate and ligulate lip with a pair or denticulate carinae. The most similar species is M. herzogii, which shares most of the same diagnostic features except for the denticulate carinae of the lip.Published as part of Rojas-Alvarado, Gustavo, Blanco, Mario A. & Karremans, Adam P., 2021, A taxonomic synopsis and morphological characterization of Myoxanthus (Orchidaceae: Pleurothallidinae), pp. 211-258 in Phytotaxa 507 (3) on page 235, DOI: 10.11646/phytotaxa.507.3.1, http://zenodo.org/record/542572
Myoxanthus antennifer Luer & Hirtz 1992

Zamora-Chinchipe: Cordillera del Condor, epiphytic in forest east of Los Encuentros, 1650 m, 21 Jan 1989, Luer et al. 14035 (holotype: MO!). Distribution: — Ecuador and Peru. Notes:— This species is frequently misidentified as M. fimbriatus (and vice versa), but M. antennifer has nonprolific ramicauls (vs. prolific ones), a lip with a conspicuous longitudinal pair of apical keels and conspicuously dentate midlobe margins (vs. lip with a longitudinal pair of low keels in the middle and a midlobe minutely dentate at the apex, frequently apiculate).Published as part of Rojas-Alvarado, Gustavo, Blanco, Mario A. & Karremans, Adam P., 2021, A taxonomic synopsis and morphological characterization of Myoxanthus (Orchidaceae: Pleurothallidinae), pp. 211-258 in Phytotaxa 507 (3) on page 230, DOI: 10.11646/phytotaxa.507.3.1, http://zenodo.org/record/542572
