1520. Puccinia balsamitae (Strauss) Rbh., Sydow04^*^- 

 Brachypuccinia. 



Tanacetum balsamita. S. Taarbsek (A. B.), 0rsl0v C/s 76 P. N.). 



1521. Puccinia tanaceti de Candolle, Sydow 04 ^*\ Renfanerust 

 (R 04 a «). 



Brachypuccinia. On the leaves and stems of Tanacetum. 



It is probable that a form on Matricaria chamomilla which I have 

 found rather scantily, F. Ringe (^/s 97 see R 99 a ^^') should be classi- 

 fied under this species. Rostrup has sometimes found two-septated 

 teleutospores.

1524. Puccinia heliantlii Schweinitz, Sydow 04 '^ Solsikkerust (R 

 02 a "5 & 04 a ■"). 



Aut-eu-puccinia. Is stated to be very common in Russia where it 

 causes rather much damage by attacking the young plants; in Den- 

 mark I have only seen st. Ill Septbr.— October.

1525. Puccinia chrysantliemi Roze, Sydow 04 ''^ Krysanthemum- 

 rust (R 02 a '«' c. icon. 6. 04 a "»), Lit: R 01 i 6. 06 p, Jacky 07 c. icon. 



This pest was very destructive to the cultivated Chrysanthemum 

 in greenhouses, when it first appeared; now it sems to be rarer pro- 

 bably because the gardeners have learned to cultivate species of greater 

 resisting power, and also probably because the fungus has changed 

 its features. It was first found in Europe in 1895 in England and 

 France (see Massee in The Gardeners Chronicle 1898 '/10), and was 

 first noticed in Denmark Jan. 14. 1898 in hothouses on slips that had 

 just been imported from England (see Bruun 98 and R 99 a ^^* "Puce. 

 Tanaceti"); in 1899 it was very common causing much damage parti- 

 cularly to the sorts of "Lincoln", "Niveum", "Etoile de Lyon" and
