52 Dr. James Macbride on Sarracenia adunca. 



The above observations were chiefly made in 1810 and 1811, 

 and have been communicated to several persons, but never to my 

 knowledge made public. From an examination which I made 

 to-day on a leaf of the S.flava about half grown, I am led to su- 

 spect that the surface, where the fly stands so unsteadily, and 

 from which it finally drops down to the bottom of the tube, is 

 either covered with an impalpable and loose powder, or that the 

 extremely attenuated pubescence is loose. This surface gives to 

 the touch the sensation of the most perfect smoothness. The use 

 of a good microscope will determine this point. 



I am, &c.
