On Bromus sterilis. ^cidia on Symphytum officinale; urediv and teleutospores on many species of Bromus, sometimes even on the inflorescence, teleutospores from June onwards. (Fig. 199.) The teleutospores germinate only after the winter's rest ; "Ward found germinable uredospores even in February and ilarch ; it has been proved that an aecidium on Fidmonaria montuna belongs to the same life-cycle. F. Miiller, E. S. Freeman, and especially Marshall Ward, have investigated the Brown Rusts of the Bromes, and have discovered a wonderful series of inter-relations among them.
