ably; while in two or three places upon the epidermal skiu of the lip, small ulcerous 

 ■ sores were formed The eftect remained some four or five days and then gradually 

 healed. The whole appearance was very much like a mild case of poisoning with 

 Rhus toxicodendron. — A. H. Y., LaFayette, Ind. 



Coreopsis aristosa, Mich. — It wall be interesting to botanists to have published 

 in the Gazette observations on the seeds and awns of Coreopsis aristosa from numer- 

 ous localities, to ascertain if the awnless or upwardly or aownwardly barbed awns are 

 inherent in the species, or if their anomalous development is incidental and attributa- 

 ble to the introduction of Bidens in the species. Here where the species largely abounds 

 the awnless with upwardly and downwardly barbed awns are i-elatively about equal in 

 all the localities I have examined the past season, where Bidens fron'dosa is numerously 

 mixed in with the growth, and also where no species of the genus now abounds, would 

 seem to indicate that the trait is au inherent one. And thus invalidating the most im- 

 portant character separating the two genera. If the species is found to be normally 

 awnless, as is quite probable, and the awns due to Bitleus, the upward and downward 

 barbs would still be a puzzle, unless it should turn out to be that both forms of barbs 

 are common also to Bidens, which is already almost established in the case of Co reoj)- 

 .ns discoidea, whicli is sometimes a perfect Bidens frondosa in all except the upwardly 

 barbed awns. The allied species Coreopsis trichosperinu, should also be examined for 

 similar anomalies whereit abounds. The species is absent from this section. Observa- 

 tions are needed in localities where Bidens is absent, and in all habitats the relative 

 proportion of the three forms should be noted. — E. Hall. 



Late Flowers.— I found the following list of plants still in flower on October 

 2d and 3d, in Exeter, R. I. It may possibly interest some western readers to see what 

 are our late flowering eastern species. I have not classified the names, but have writ- 

 ten them somewhat in the order in which the specimens were found. It will be noticed 

 that some are early plants enjoying a second bloom:
