Instead, another member of the team, Margaret Fleming, a postdoctoral researcher, brought them to a cold room, where she removed some seeds of Setaria glauca — a species of millet, which hasn’t sprouted in the experiment since 1914 — for genetic analysis.

Typical micro-colinearity patterns among genomic regions from Oropetium, Setaria, Sorghum, Oryza and Brachypodium are shown.

Other grasses present included Triodia flava, common in House Field, but with only spotty distribution in Quarry Field; Elymus canadensis, distributed over both areas in spotty fashion and almost always showing evidence of use by voles and other small mammals; Aristida oligantha and Bouteloua curtipendula, both more common on the higher and drier Quarry Field; Panicum virgatum, Setaria spp., especially on disturbed areas; and three bluestems, Andropogon gerardi, A. virginicus and A. scoparius.

It is still uncertain whether the other kinds of grass, Poa and Setaria Holcus, belong exclusively to St. Paul, or are to be included in the more general group of geographical plants known as that of the islands of Edward's Island, Kerguelen's Island, and St. Paul.
