' VERNON AND KREIG. 
About the fame time with Banister^ 
as I conjecture, Mr. William Vernon, fel- 
low of St. Peter's College, Cambridge^ and 
Dr. David Kreig, a German phyfician, 
led by their genius for botany, made a 
voyage to Maryland, They returned, after 
having colieded an Herbarium of feveral 
hundred nev/ and undefcribed plants. Thefe 
came into the poffeffion of Sir Hant 
Sloane, by whofe liberal communication 
they were inferted in the Supplement '* 
to Ray's Hiftory. Mr. Vernon is alfp 
fpoken of by Ray, as not lefs fkilful and 
affiduous in the purfuit of Englifo plants^ 
* Mr, Houston confecrated to Banister a genus 
Decandrous climbing plants, which Sloane, Pluke- 
NE7, and Plumier had ranked with the Aer .\ But the 
diftinftion of Houston ftood the teft of the Linncean 
4ules, and is prefer ved in the (exual fyftem.
