Gaura coccinea Pursh. A bed of this was found in June, 1910, 

 beside the track of the Michigan Central Railroad at Crisman, 

 Porter County, Ind. Being near the station and much exposed 

 it soon after disappeared or was destroyed. But it showed its 

 ability to migrate eastward from its native region in the distant 

 west, and will doubtless become established in places where not 

 molested. It was in full flower June 13, when discovered, the 

 rather dense bed well covered with rose colored and scarlet 

 flowers. 



Gaura parviflora Dougl. Found in dry open oak woodlands 

 bordering Long Run Creek, town of Lockport, 111. While visiting 

 this locality in August, 191 2, to get specimens of Fontinalis 

 Umbachii Card., which grows abundantly in this part of the 

 creek, Mr. W. N. Clute, who was in company with me, brought 

 from the neighboring woods some plants of a Gaura that differed 

 from G. biennis L., the common one here, calling attention to this 

 difference, We concluded it was G. parviflora. In visiting the 

 spot I found G. biennis associated with G. parviflora, both showing 

 their characteristic features. The station being farther east 

 than the range usually assigned to the species, apparently un- 

 recorded heretofore for the region, the question at once arose 

 whether it was introduced. But this seemed hardly compatible 

 with the location, since it was fully a mile from the nearest rail- 

 road and a quarter of a mile from any public highway. All 

 indications pointed to the fact that it was as much at home and 

 indigenous as its companion, G. biennis. Some of the plants 

 were very stout, the stems at the base about an inch in diameter 

 and correspondingly tall. The range commonly assigned is west 

 of the Mississippi.
