Taxonomic and floristic notes on neotropical Macromitrioideae (Orthotrichaceae)
Upon examination of type material, the following new synonymies are proposed: Macromitrium altituberculosum Bartr. with M. carionis C. Muell.; M. aureum C. Muell. with M. longifolium (Hook.) Brid.; M. crumianum Steere & Buck with M. leprieurii Mont.; M. semimarginatum C. Muell. with Groutiella chimborazense (Spruce ex Mitten) Florsch.; M. standleyi Bartr. var. subundulatum Bartr. with M. fulges...
متن کاملMolecular phylogeny of the neotropical genus Christensonella (Orchidaceae, Maxillariinae): species delimitation and insights into chromosome evolution.
BACKGROUND AND AIMS Species' boundaries applied within Christensonella have varied due to the continuous pattern of variation and mosaic distribution of diagnostic characters. The main goals of this study were to revise the species' delimitation and propose a more stable classification for this genus. In order to achieve these aims phylogenetic relationships were inferred using DNA sequence dat...
متن کاملFloral display and mating patterns within populations of the neotropical epiphytic orchid,Laeliarubescens (Orchidaceae).
Pollinator behavior plays a central role in determining patterns of pollen-mediated gene movement in zoophilous angiosperms. A species' floral display can strongly influence the behavior of its pollinators and thereby affect its evolutionary pathway. We used paternity analysis to directly measure and describe mating patterns within 15 populations of the epiphytic orchid, Laelia rubescens, in Co...
متن کاملNeotropical roots of a Polynesian spice: the hybrid origin of Tahitian vanilla, Vanilla tahitensis (Orchidaceae).
Absent in the wild, Tahitian vanilla (V. tahitensis) is a gourmet spice restricted in distribution to cultivated and feral stands in French Polynesia and Papua New Guinea. Its origins have been elusive. Our objective was to test the purported hybrid derivation and parentage of V. tahitensis from aromatic, neotropical progenitors. Nucleotide sequences from V. tahitensis and neotropical Vanilla w...
متن کاملWidespread mycorrhizal specificity correlates to mycorrhizal function in the neotropical, epiphytic orchid Ionopsis utricularioides (Orchidaceae).
Tropical orchids constitute the greater part of orchid diversity, but little is known about their obligate mycorrhizal relationships. The specificity of these interactions and associated fungal distributions could influence orchid distributions and diversity. We investigated the mycorrhizal specificity of the tropical epiphytic orchid Ionopsis utricularioides across an extensive geographical ra...
