Joanna Mytnik
As a biologist, I am broadly interested in the taxonomy and phylogeny of plants. My empirical systematic research interests have been on the family Orchidaceae with a major focus on the tropical taxa, especially from Africa.
I am interested in species-level problems including species delimitation and classification, interspecific hybridization and geographical patterns of species diversification.
In recent years I mainly worked on taxonomy and phylogeny of the orchid subtribe Polystachyinae, a group including fascinating pantropical 230-species genus Polystachya. A comprehensive monograph of the subtribe was published in 2011.
I currently work on the long-term project concerning the orchid flora of Africa.
My second lifelong passion is teaching with the goal to inspire my students. The subject I am interested in the most is gamificationand and I gamify academic courses at the University of Gdansk (Poland). The teaching (and learning!) is not boring any more:)

from Colombia are described. Each species is illustrated,
and detailed habitat and distribution data are provided. A
distribution map of the new species is presented. A
dichotomous key for determination of the Gomphichis
species in northern South America is provided. Conservation
status assessments are provided for each species;
current International Union for Conservation of Nature
(IUCN) Red List categories and criteria are listed. A brief
discussion of spiranthoid orchids taxonomy, conservation
status of species, endemism in the Andes and paramo are
presented.
Keywords: Africa, Bayesian analysis, ITS, lectotypification, molecular phylogeny, maximum parsimony, morphology, Polystachyinae, rpl16, rpl32-trnL, taxonomy.

Although the nomenclature used in this excellent treatment may differ from the World Checklist of Selected Plant Families, this book is a valuable tool to identify the orchids of French Guiana. Whether a professional scientist or avid hobbyist you will not be disappointed. This book will make a valuable addition to any orchid library."

Orchids of French Guiana. 2012. 598 line - figs. 877 col. photogr. on pls. 653 p. 4to. Hardcover. (ISBN 978-3-905997-02-6)
Abstract:
The present study is based on herbarium materials and field expeditions carried out by Szlachetko in 1997 and 1999. Total number of specimens revised was about 4500. The keys for taxa determination are dichotomous. Subfamilies, tribes and subtribes are placed in the taxonomic order (Szlachetko 1995 with later changes by Slachetko & Rutkowski 2000, Slachetko & Margosnka 2002, Slachetko 2003, and Szlachetko & Mytnik - Ejsmont 2009). The account of every species contains: Latin name, abbreviation of authors' surnames, citation, synonymy, taxonomic description, ecology, distribution and list of representative specimens. French Guiana (Guyane Francaise) is an overseas department of France situated in the north - east part of South America. It borders Brazil to the east and south, Suriname to the west and the Atlantic Ocean to the North. The eastern and western borders are naturally demarcated, following the rivers Oyapoch and Maroni. The southern borders runs along the Tumuc - Humac Mountains. French Guiana extends 450 km from north to south and 300 km east to west. 95.5% of the forested areas consist of primary equatorial forest, unchanged by settlers, of the highest biodiversity. This makes French Guiana a country whose flora has changed a little, thus providing an interesting field for research into biological diversity. - This monograph is richly illustrated.

montane and submontane African epiphytes with thirteen
species (including the newly described in this paper).
During a scientific expedition to Bamenda Highland,
Cameroon a new species, Polystachya bamendae, was
found and it is described here. The new entity was compared
with 398 herbarium specimens representing the
section, including the type collections. The molecular
analyses of the ITS and matK strongly support the results
of morphological studies and reveal close relationship
between the new species and the species of the section
Superpositae. Two hypotheses supporting function of the
matK gene in the examined species are presented. The
phylogenetic and morphological relation of Polystachya
bamendae to P. lindblomii and P. superposita is discussed.
The distribution range of the section is analyzed and a
discussion about the distribution of the species is presented.
A distribution map of the section and dichotomous key to
the species of Superpositae are provided. The occurrence
of the species of the section in two Biodiversity Hotspots
(Guinea Forests of West Africa and Eastern Afromontane)
is discussed.
