The urge to organise the world around us is an essential part of human nature. Naming and categorising enable us to store and access information ef ciently. The need to name and categorise extends to the natural world and, in particular, to living organisms. The science underpinning this area of knowledge is called Taxonomy, and is as old as humani...

Several names of the genus Pinguicula have been found to need typification or corrections to previous typifications. Analyses of original material and literature related to each name have led to the designation of 17 lectotypes, five neotypes and one epitype. Also five previously cited ‘holotypes’ were corrected to lectotypes. Notes discussing the...
The carnivorous plant Pinguicula filifolia occurs in western Cuba and shows a restricted distribution due to habitat specificity associated with poor wet soils. Its populations are distributed mainly in south Pinar del Río (Cuba) and in Isla de la Juventud. Plants from one isolated location in NW Pinar del Río shows morphological differences with r...
Background: Phenotypic variations have been observed in populations of west Cuban Pinguicula species. Such populations occur in patches under different ecological conditions associated with specialised habitats and separated by geographical and ecological barriers, which can lead to morphological differentiation.
Aims: To analyse morphological dive...

I'm mapping plant fossil registry based on paleocoordinates.
Dear colleagues,
I am having some problems with node dating using substitution rates in MrBayes 3.2.6, even following the example in the program manual.
According to the manual I need to:
1. Set a normal distribution as the prior for the clock rate: e.g. using 0.02 as the mean and 0.005 as the standard deviation assuming the rate is approximately 0.01 ± 0.005 substitutions per site per million years:
MrBayes > prset clockratepr = normal(0.01,0.005)
2. Modify the tree age prior to an exponential distribution with the rate 0.01:
MrBayes > prset treeagepr = exponential(0.01)
When I run the analysis, the program does not recognize the argument “exponential” to modify the age prior:
No valid match for argument “exponential”
Invalid Treeagepr argument
Error when setting parameter “Treeagepr”
I have checked the "Command Reference for MrBayes ver. 3.2.6" and, in fact, “exponential” does not appears as a valid argument for Treeage parameter, so I think it is an error in the manual but I cannot find a way to solve it. .
Does anyone have had such situation before?
Any solution to solve the problem?
Many thanks,
Yoannis
I am looking for a protocol to isolate and mount fossil pollen plates from coastal sediments. I have a little experience working with fresh plant material for pollen analysis.
Thanks!
I'm working on an interespecific phylogeny of psbA-trnH haplotypes and I would like to run Bayesian and Maximum Likelihood analyses considering gaps as fifth base. There are some indels blocks specific to each species, then I think this information is important in the separation of the three species involved in the analysis. Could anyone tell me which software can I use to run a Maximum Likelihood analysis considering gaps as fifth base?
Does somebody know/use a method for phylogeny calibration of groups without fossil records? I've read about calibration using genetic distance of sequences to estimate approximate divergence times but I really don't know how it works.
Any advice?

In 2010, I started to compile a database of information on all Pinguicula species and infraspecific taxa. This started as a side project of my PhD project focussed on Cuban Pinguicula species but it became clear that there were gaps and other issues in the taxonomic and nomenclatural treatment of the genus. Thus, the aim of this project is to clarify and correct the nomenclatural status of all names proposed within the genus Pinguicula.
My work includes the review of the protologues and other relevant literature and the trace and review of all putative original material related to each name. During the development of the project, I have been assisted by curators and other staff members from various herbaria around the world, as well as by other researchers with whom I discuss ideas and findings in search of nomenclatural solutions.
I am open to collaborate with curators and other researchers in order to continue this project.
The main aim of this project is to propose a solid hypothesis for the evolution and diversification of Lentibulariaceae lineages based on DNA and morphology.
The aim of the project is the taxonomic review of the family Lentibulariaceae as part of the brazilian program Reflora.
