4S6 DECANDRIA. MONOGYNIA. pyrolao 



Corolla white, with a tinge of purple ; petals broad ovatCo 

 Statncns sometimes \2 \ Jilaments bearing a flattened obcor-= 

 date villous disk ; anthers large ; the tubular pores at the 

 base divergent and truncated obliquely. Stigma large, sessilCj 

 partly immersed in the germen. 

 Hab In dry woods. July — August. 



This, and the preceding species, form the genus Chima° 

 PHILA of Pur s h. This acute Botanist separated them Py- 

 BOL^, as was long before proposed by Mi c h a u x, on ac-* 

 count of their sessile stigmas, and the anthers being rostrate 

 and opening by a subbivalve foramen. But in their anthers 

 they certainly agree with the other PyROLiE, opening by 2 

 simple pores at their base ; and in the stigma, they differ from, 

 each other, it being furnished with a short style in P. umbellata^ 

 and quite sessile in P macuiata. Dr. Big e low, in '.is Me- 

 dical Botany, above qnoted, under the article Pyrola umbel- 

 latay has given excellent reasons for I'etaining these species iu 

 the genus where they were originally placed, and has shewn 

 that they diflFer as much from each otlter, as some true Py- 

 rola do from these. t In Air. JVji t f all's improved gene- 

 ric character of Chimaphila, he describes the filaments as sti- 

 pitate, with a ciliate discoid stipe, and the capsule with the 

 valves unconnected by a web. In P. secunda, however, the 

 valves of the capsule are likewise unconnected. It appears to 

 me, therefore, better to restore Pursh's genus to Pyrola.
