A couple new papers: plant tree of life and quartet sampling

A couple of our papers just came out in the Tree of Life special edition of AJB. Pease et al. Quartet Sampling distinguishes lack of support from conflicting support in the green plant tree of life looks at different ways to examine support in a phylogeny using a bunch of green plant examples. Smith and Brown Constructing a broadly inclusive seed plant phylogeny uses OpenTreeOfLife and GenBank to make a big dated seed plant phylogeny.
