NOTES OX THE PLAXTS OF THE YEAR. 

 F. L. Harvey. 



Specimens of the plants mentioned below were examined dur- 

 ing the year. The weeds received agree well with weed seeds 

 found in seed offered for sale in Maine. Judging from increased 

 correspondence, farmers are awakening to the importance of bet- 

 ter seed and the necessity of carefully watching their fields to 

 prevent the introduction and spread of new weeds. A large 

 number of samples of seeds sold in Maine were examined the 

 past season and over sixty kinds of foreign seeds detected. 



But few^ fungi were reported as doing damage the past season. 



Hollyhock Rust. {Puccinia nialvaceariim.) This dis- 

 ease has established itself in Maine. 



Potato Blight. {Phyfophthora infestans). Was quite bad 

 in some portions of Maine, but not so prevalent as in 1897. 



Wild Pepper Grass. (Lepidiuin znrginicurn and apetalum.) 

 In newly seeded land. The clover seed sold in !Maine contains 

 the seeds of these weeds. 



Wild Turnip. (Brassica campestris.) Appeared in fields 

 sowed with western clover seed. 



Wild ^Iustard. (Sinapis alba.) In land seeded with 

 western clover seed. This is not as common in Maine as sev- 

 eral other cruciferous weeds. 



Purple AItlkv/ort. (Poly gala z'iridcscciis L.) Growing 

 along roadsides and in meadows. X'ot a bad weed. 



Rough Cixquefoil. (Poteiifilla inonspeliciisis.) In newly 

 seeded land. The seeds of this plant are abundant in Timothy 

 seed sold in ]\Iaine. 



BiEXxiAL \\'ormwood. (Arteiucsia hieyinis.) Dooryards 

 and waste places. X'ot a bad weed.
