Summary of the results for Ericales to which Lecythidaceae belongs
The monophyly of Ericales is well supported (BS = 100%), but as in other recent studies, resolution within the clade is more problematic. Our study retrieves a well-supported clade (BS = 100%) of Tetrameristaceae + (Marcgraviaceae + Balsaminaceae) (see Schönenberger et al., 2010 ) as sister to the remaining Ericales, which are also well supported as monophyletic (BS = 95%), but within which relationships are even more uncertain, mirroring earlier analyses by Schönenberger et al. (2005) based on 11 genes. Lecythidaceae are strongly supported (BS = 95%) as sister to the remainder, although in the 11-gene study with much greater taxon sampling (Schönenberger et al., 2005 ), Lecythidaceae were placed in a polytomy at this node. Three other well-supported clades were recovered: (1) Polemoniaceae + Fouquieriaceae (BS = 92%), (2) a clade (BS = 98%) of Actinidiaceae + Sarraceniaceae sister to a clade (BS = 100%) of Clethraceae + (Cyrillaceae + Ericaceae) (BS = 100%), and (3) a Primulaceae s.l. clade (BS = 100%) in which Maesa is sister to Clavija + Primulaceae s.s. (BS = 100%). As in the 11-gene analysis (Schönenberger et al., 2005 ), the relationships of Diapensiaceae, Ebenaceae, Sapotaceae, Ternstroemiaceae, and Theaceae are not well supported here. A recent 23-gene analysis with approximately 90 taxa of Ericales resolves many of these latter placements (K. Sytsma et al., unpublished manuscript).
