SHORTER NOTES 



A New Station for Ccelopleurum actaeifolium. — The 

 seventh edition of Gray's Manual gives "Mass. to Greenl." as 

 the range of Coelopleurum actaeifolium (Michx.) Coult. & Rose. 

 In the Bulletin of the Torrey Botanical Club for February, 1914, 

 Bicknell notes the occurrence of the species on the island of 

 Nantucket and states that this "seems to be the southernmost 

 point to which this northern plant has made its way." In July, 

 1916, the writer discovered the Coelopleurum near the western 

 end of Fisher's Island, New York, growing in thickets close to 

 the shore but not among the actual beach plants. This station 

 is in about the same latitude as Nantucket but marks an inter- 

 esting extension of range to the westward. The plants were 

 numerous and robust and the bractlets of the involucels were, 

 in some cases, strikingly large and conspicuous. Specimens 

 have been deposited in the herbaria of Yale University, Harvard 

 University, and the New York Botanical Garden.

Shreve's Vegetation Map of the United States* 



There have been many more or less satisfactory attempts to 

 map the forests or other natural vegetation of areas varying in 

 size from a few acres to the whole world. When the area is 

 small enough for one person to explore it pretty thoroughly, and 

 the vegetation types are clearly defined and not much disturbed 

 by civilization (as is the case in some parts of Florida, for ex- 

 amplef) the task is simple enough. A vegetation map of the 

 world or a whole continent is also comparatively easy to make, 

 because only a few types need to be represented, and errors of

 graphical Review 3: 119-125, with folded map 12^ x 20 in. Feb. 1917. 



t In the 7th Annual Report of the Florida Geological Survey (1915), following 

 page 134, is a map of the vegetation of about 1000 square miles in the central 

 part of the state, made by two young men with little or no botanical training, 

 who did remarkably well under the circumstances. Many foresters have made 

 equally good maps of areas of similar size.
