Abstract
THE æcidium on Ornithogalum species in Europe has an interesting nomenclatorial history. At first attributed to Puccinia liliacearum Duby, it was recognized by Bubak1 as belonging to a separate hetercecious rust and named by him Æcidium ornithogaleum. Then, in 1914, Tranzschel2 demonstrated in both directions its connexion with the common brown rust of barley, Puccinia hordei Otth. (syn. P. anomala Rostr.). This connexion has been confirmed by Mains and Jackson3 in the United States of America ; but, so far as we are aware, the æcidium has not hitherto been found in Britain. According to Sydow4, it is known to occur in Germany, Austria and Hungary. D‘Oliveira5, who repeated Tranzschel‘s experiments and produced æcidia on Ornithogalum by inoculation from barley, was unable to find the æcidia in the field in England and concluded that barley rust survives the English winter in the uredo state on barley tillers and seedlings.
