NOTE ON OXALIS STRICTA VAR. VIRIDIFLORA. 
HARLEY HARRIS BARTLETT. 
Mr. Henri Hus has described ' a green-petaled variety of Oxalis 
stricta from the vicinity of St. Louis. During the summer of 1907 this 
variety was found, in plenty, growing among piles of dead brush at 
the edge of a pine barren near Thomson, Georgia. The effect of 
the habitat was to make the plants long and spindling, but otherwise 
they could have been distinguished from the typical form of neighbor- 
ing fields only by floral characters. 
The petals of Oxalis stricta var. viridiflora are light green in color, 
obcordate, much broader than those of the typical form, and of some- 
what firmer texture. They do not close after having once opened, and 
remain at the base of the developing fruit for several days before 
wilting. In the typical form the petals open in the morning and close 
toward mid-day. They wilt while closed, and are often borne up as
