852 RETORT OF STATE GEOLOGIST. 



ANOGRA Spach. 



A. albicaulis (Pursh) Britton. Prairie Evening Primrose. 

 (CEnothera albicaulis Nutt.) 

 An exceptional form of occasional occurrence in the southern 

 counties. Its northern limit in the State seems to he in Hamil- 

 ton County (Wilson), where it occurs along the L. E. & W. 

 Kail way. 



KNEIFFIA. 

 K. pumila (L.) Spach. 



(CEnothera pumila L.) 

 In dry situations in the northern part of the State. 

 Herbarium specimens from Laporte (Barnes), and Noble (Van 

 Gorder). 



K. fruticosa (L.) Kaimann. Sundrops. 



(CEnothera fruticosa L.) 



As a rule found only in low, rich soils, although occasionally 

 found in dry localities. The species is very variable, and is fre- 

 quently incorrectly referred. 



It flowers most profusely in May and June, although occasional 

 flowers may be seen late in August.

 (Clements); Jasper (Barnes); Monroe (Blatchley); Jefferson (J. 

 M. Coulter); Jay, Delaware, Randolph, and Wayne (Phinney); 

 Clark (Baird and Taylor); Cass (Hessler). 



LAVAUXIA Spach. 



L. triloba Watsonii Britton. Three-lobed Primrose. 

 (CEnothera triloba parviflora S. Wats.) 

 This western form is reported from Monroe County by W. S. 

 Blatchley, as "frequent along streams and in gravelly soil." 

 The flowers were collected in July. 



It is possible that this reference should be to L. triloba (Nutt.) 

 Spach., a form naturally in our territory in such soils, and withal 

 extremely variable. 



GAURA L. 



G. coccinea Pursh. Scarlet Gaura. 



In dry soil, flowering in July and August. Reported only 

 from Fayette County by Robert Hessler. The form is so decidedly 

 western in its range that its occurrence in a single locality in the 

 State must he looked upon as due to some exceptional means of 

 distribution. (A railroad migrant. R. H.)
