Professor Greene has done botanists a valuable service in re- 
printing this old pamphlet, thus putting it within reach of every- 
body. The original is extremely rare. It was published in Lon- 
don in 1813, compiled by Thos. Nuttall. Its full title is “A 
Catalogue of New and Interesting Plants collected in Upper 
Louisiana and principally on the River Missourie, for sale at 
Messrs. Fraser’s Nursery for curious American Plants, Sloane 
Square, King’s Road, Chelsea, London.” Professor Greene 
points out that Yucca glauca of this catalogue antedates Y. an- 
gustifolia, and Dalea enneandra antedates D. laxiflora, Pursh., 
and that Sideranthus is older than either Chrysopsts or Aplopap- 
pus. The copy is taken from the pamphlet preserved in the 
library of the Philadelphia Academy of Natural Sciences which 
belonged to Zaccheus Collins. Nits 8,
