A NEW STATION FOR POGONIA AFFINIS. 

 E. Jerome Grimes. 



June 1st, 1920, I was lucky enough to find three flowering speci- 

 mens of that rare, interesting, and much discussed orchid, Pogonia 

 affinis Austin, while making a hurried trip through some woods west 

 of Williamsburg, which is situated on the coastal plain about 30 

 miles west of Norfolk, Virginia. This year the same station was 

 visited the beginning of the second week in May and, by diligent 

 searching throughout the afternoon, fifteen plants each consisting of 

 a flowering shoot were observed. The difference in flowering dates 

 is due to the season, which was three weeks to a month earlier in 

 1921. 



The habitat is a flat dry hardwood on a gently undulating inter- 

 stream area. The soil is a well drained gray fine sandy loam over a 

 yellowish sandy clay or clay. The vegetation consists chiefly of 

 white oak, beech, tulip and chestnut with a few scattering Loblolly 

 pines, and an abundance of flowering dogwood. The undergrowth 

 is very sparse and the Pogonias were found scattered over an area 

 of about ten acres, occurring either singly or in open groups of two 

 to four plants. 



A composite soil sample of the habitat was tested and found to be 

 practically neutral to Brom Thymol Blue, and soil shaken from the
