Rubiaceae), and the Description of the New Species Galianthe Vasquezii from Peru and Colombia
Morphological and molecular data confirm the transfer of homostylous species in the typically distylous genus Galianthe (Rubiaceae), and the description of the new species Galianthe vasquezii from Peru and Colombia Javier Elias Florentín1, Andrea Alejandra Cabaña Fader1, Roberto Manuel Salas1, Steven Janssens2, Steven Dessein2 and Elsa Leonor Cabral1 1 Herbarium CTES, Instituto de Botánica del Nordeste, Corrientes, Argentina 2 Plant systematic, Botanic Garden Meise, Meise, Belgium ABSTRACT Galianthe (Rubiaceae) is a neotropical genus comprising 50 species divided into two subgenera, Galianthe subgen. Galianthe, with 39 species and Galianthe subgen. Ebelia, with 11 species. The diagnostic features of the genus are: usually erect habit with xylopodium, distylous flowers arranged in lax thyrsoid inflorescences, bifid stigmas, 2-carpellate and longitudinally dehiscent fruits, with dehiscent valves or indehiscent mericarps, plump seeds or complanate with a wing-like strophiole, and pollen with double reticulum, rarely with a simple reticulum. This study focused on two species that were originally described under Diodia due to the occurrence of fruits indehiscent mericarps: Diodia palustris and D. spicata. In the present study, classical taxonomy is combined with molecular analyses. As a result, we propose that both Diodia species belong to Galianthe subgen. Ebelia. The molecular position within Galianthe, based on ITS and ETS sequences, has been supported by the following morphological Submitted 10 June 2017 characters: thyrsoid, spiciform or cymoidal inflorescences, bifid stigmas, pollen grains Accepted 19 October 2017 with a double reticulum, and indehiscent mericarps. However, both species, unlike the Published 23 November 2017 remainder of the genus Galianthe, have homostylous flowers, so the presence of this Corresponding author type of flower significantly modifies the generic concept. -

High Species Diversity in Fleshy-Fruited Tropical Understory Plants
vol. 157, no. 6 the american naturalist june 2001 High Species Diversity in Fleshy-Fruited Tropical Understory Plants James F. Smith* Department of Biology, Boise State University, Boise, Idaho 83725 increased species diversity is to compare multiple instances in which the trait has evolved. If the trait has resulted in Submitted July 10, 2000; Accepted February 1, 2001 increased species diversity, then clades with the trait should be more diverse than clades lacking the trait. Older clades are more likely to have generated more species; therefore the clades to be compared must be equivalent in age (e.g., abstract: Key innovations may increase the number of taxa in a sister groups). Therefore, accurate phylogenetic assess- clade that possesses the proposed innovation in comparison to its ments are critical in assessing specific characters and their sister group that lacks the trait through either increased speciation effects on species diversity. Recent advancements in phy- or reduced extinction rates. Comparing sister clades across several independent lineages provides statistical support that the trait has logenetic analysis have improved our understanding of increased species diversity. Previous studies have indicated that there evolutionary relationships for many groups, especially may not be a relationship between biotic dispersal and higher species among plants. This improved phylogenetic assessment of diversity, but only a few of these studies specified habit, habitat, or plant relationships has allowed evolutionary biologists to type of disperser. No previous study has specified all of the above examine many traits previously proposed as affecting spe- parameters and used a phylogenetic approach. This article examines cies diversity in a new light. -

Abstract As part of the studies carried out in the species of Diodia from the Americas, we present a discussion of the taxonomic identity of Diodia angustata. Based on the study of recent collections and original materials, we propose to transfer the species to the genus Planaltina, as P. angustata. A dichotomous key for all species of the genus is included. The pollen morphology is also analyzed and compared with other species of Planaltina. Images of the plant on its environment are provided.

Any substantive modifications will be posted under the author’s name on the Biology Department web page at the Holy Cross web site. The author can be contacted through the Biology Department or at [email protected]. Cover Illustrations: Pictured are three species portraying different aspects of the Worcester flora. Acer platanoides, or Norway maple, is a non-native species and the most commonly planted street tree in Worcester. It is prominent in many City woodlands, where it competes with native species. The grass Elymus villosus is a state threatened species. The Worcester record is the only known occurrence of the species in Worcester County. The orchid Calopogon tuberosus, a native bog species, is known in the City only from historical records. Figures reprinted from Holmgren et al.
