These data are presented in support of a plastid phylogenomic analysis of the recent radiation of the Hawaiian endemic mints (Lamiaceae), and their close relatives in the genus Stachys, "The quest to resolve recent radiations: Plastid phylogenomics of extinct and endangered Hawaiian endemic mints (Lamiaceae)" [1]. Here we describe the chloroplast genome(More)
Owing to unavoidable circumstances only a limited amount of time was available for the work on agglutination. The foregoing report is therefore preliminary only and the following conclusions are provisionally offered: I. Pneumococci by reason of their agglutinating properties exhibit a tendency to separate into numerous groups similar to streptococci. II.(More)
