Última Three new rarely collected or endangered species of Annonaceae from Venezuela Naturalis Chatrou, L.W.; Pirie, M.D.. Three new species of Annonaceae from Venezuela are described here: Cremastosperma venezuelanum Pirie, Klarobelia subglobosa Chatrou, and Pseudomalmea wingfieldii Chatrou. All three are represented by few collections (in comparison to those of other Neotropical species of Annonaceae). Klarobelia subglobosa and P. wingfieldii in particular are only known from a few individual specimens collected in areas vulnerable to habitat destruction. IUCN threat categories are assigned to these species. Tipo: Article / Letter to the editor Palavras-chave: Annonaceae; Cremastosperma; Klarobelia; Pseudomalmea; Neotropics; Venezuela; Threatened/endemic species. Ano: 2005 URL: http://www.repository.naturalis.nl/record/525516 Taxonomic novelties in the genus Campylospermum (Ochnaceae) Naturalis Bissiengou, P.; Chatrou, L.W.; Wieringa, J.J.; Sosef, M.S.M.. Four new species, one with two subspecies, of the genus Campylospermum are described, all endemic or sub-endemic to Gabon. These are C. auriculatum, C. gabonensis, C. gabonensis subsp. australis, C. glaucifolium and C. occidentalis. Distribution maps and scans of the holotypes are provided as well as preliminary IUCN Red List assessments. New combinations for nine species formerly assigned to the genus Ouratea and/or Gomphia are proposed: C. andongensis, C. glomeratum, C. longestipulatum, C. lunzuensis, C. lutambensis, C. nutans, C. plicatum and C. warneckei. Finally, one taxon is raised from the variety to species level, leading to the new combination C. costatum.

Ano: 2013 URL: http://www.repository.naturalis.nl/record/525772 Assessment of age and greenness of herbarium specimens as predictors for successful extraction and amplification of DNA Naturalis Erkens, R.H.J.; Cross, H.; Maas, J.W.; Hoenselaar, K.; Chatrou, L.W.. Age and the greenness of leaves have been frequently used as indicators for selecting herbarium specimens for molecular studies. Although plant DNA extraction and amplification have been common lab procedures for the past 20 years, no studies specifically investigated the success of these indicators. Here the predictive value of age and the greenness for extraction and amplification success is assessed, using a large number of herbarium specimens from different plant groups. The investigation of these indicators is important because herbarium material is a precious commodity, and is often the only remaining floral record of now extinct ecosystems. In cases where little leaf material is available, most researchers still attempt to extract DNA. This study...

Ano: 2008 URL: http://www.repository.naturalis.nl/record/525744 Seven taxonomic discoveries in Annonaceae from south-eastern Central America Naturalis Erkens, R.H.J.; Maas, P.J.M.; Chatrou, L.W.; Schatz, G.E.; Zamora, N.. During fieldwork in Costa Rica and Panama five undescribed species of Guatteria and one new species of Desmopsis were collected and are described here. Additionally, a poorly known species of Pseudomalmea is described. Tipo: Article / Letter to the editor Palavras-chave: Annonaceae; Desmopsis; Guatteria; Pseudomalmea; Costa Rica; Panama; Endemics. Ano: 2006 URL: http://www.repository.naturalis.nl/record/525819 Diversification of myco-heterotrophic angiosperms: evidence from Burmanniaceae Naturalis Merckx, V.; Chatrou, L.W.; Lemaire, B.; Sainge, M.N.; Huysman, S.; Smets, E.F.. Background: Myco-heterotrophy evolved independently several times during angiosperm evolution. Although many species of myco-heterotrophic plants are highly endemic and longdistance dispersal seems unlikely, some genera are widely dispersed and have pantropical distributions, often with large disjunctions. Traditionally this has been interpreted as evidence for an old age of these taxa. However, due to their scarcity and highly reduced plastid genomes our understanding about the evolutionary histories of the angiosperm myco-heterotrophic groups is poor. Results: We provide a hypothesis for the diversification of the myco-heterotrophic family Burmanniaceae. Phylogenetic inference, combined with biogeographical analyses, molecular divergence time estimates,...
