Ayanganna https://phytokeys.pensoft.net/article/39105/ PhytoKeys 154: 11-17

DOI: 10.3897/phytokeys.154.39105

Authors: Harold Robinson, G. Karen Golinski

Abstract: A relative of the African species described by Brotherus as Bryum perspinidens, has been discovered in Guyana with erect capsules and a short inner peristome. The Guyana material is recognized as a new species, and both species are placed in the genus Brachymenium. The characteristics that distinquish the genus are discussed with reference to the Guyana specimens of Brachymenium speciosum.

Taxonomic revision of Neotropical Murdannia Royle (Commelinaceae) https://phytokeys.pensoft.net/article/9835/ PhytoKeys 74: 35-78

DOI: 10.3897/phytokeys.74.9835

Authors: Marco Octávio de Oliveira Pellegrini, Robert B. Faden, Rafael Felipe de Almeida

Abstract: This study provides a taxonomic revision for the Neotropical species of the genus Murdannia. Six species are recognized as native, including a new species and a new combination, while two Asian species are recognized as invasive. We present an identification key, a table summarizing the morphologic differences among the species, a new synonym, six lectotypifications, a distribution map, and descriptions, comments and photographic plates for each species. We also provide comments on the morphology of the Neotropical species of Murdannia, comparing them with the Paleotropical species, and a discussion of inflorescence architecture in the genus as a whole.

Two new combinations in Euploca Nutt. (Heliotropiaceae, Boraginales) and a conspectus of the species of the Guiana Shield area https://phytokeys.pensoft.net/article/6260/ PhytoKeys 61: 101-124

DOI: 10.3897/phytokeys.61.6260

Authors: Christian Feuillet

Abstract: Heliotropium foliatum and Tournefortia humilis are transferred to Euploca Nutt. respectively as Euploca foliata comb. n. and Euploca humilis comb. n. A collection from Guyana has been recently identified as Euploca humistrata, a species previously considered a Brazilian endemic. A collection from French Guiana documents for the first time the species in that country. A key to the species of the Guiana Shield area is given. The species of Euploca from the Guiana Shield are listed with synonymy and a brief description: E. filiformis, E. humilis, E. humistrata, E. lagoensis, E. polyphylla, E. procumbens.

Description and molecular diagnosis of a new species of Brunfelsia (Solanaceae) from the Bolivian and Argentinean Andes https://phytokeys.pensoft.net/article/1408/ PhytoKeys 10: 83-94

DOI: 10.3897/phytokeys.10.2558

Authors: Natalia Filipowicz, Michael Nee, Susanne Renner

Abstract: Brunfelsia plowmaniana N.Filipowicz & M.Nee sp. nov., a species from humid and cloud forests of the Bolivian and Argentinean Andes, is described and provided with a molecular diagnosis, using provisions available in the recently approved International Code of Nomenclature for algae, fungi and plants. Specimens belonging to the new species were previously placed in the polymorphic B. uniflora (Pohl) D.Don, which a molecular phylogeny revealed as polyphyletic. Revision of numerous collections revealed clear morphological differences between the new species and B. uniflora, the type locality of which is in the state of São Paulo, Brazil.
