On Bronnis stcrilis. yEcidia on SympJii/tiiin officinale; uredo- and teleutospores on many species of Brortius, sometimes even on the inflorescence, teleutospores from June onwards. (Fig. 199.) The teleutospores germinate only after the winter's i-est ; Ward found germinable uredospores even in February and March ; it has been proved that an gecidium on Pulmonaria montana 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.
