HAY-SCENTED FERN. 



Filicum have also added the species of Cibotium to Dicksonia, 

 but these have the outer half of the involucre separate from 

 the lobule; and this character, with their peculiar habit, is, 

 perhaps, enough to justify their being kept distinct. The 

 oldest name for our plant is Nephrodium punctilobulum, of 

 Michaux, published in 1803. In 1806, Swartz called it Aspid- 

 ium punctilobulum. In 1809, Willdenow named it Dicksonia 

 ■pilosiuscula, and in the same year, as nearly as I can discover, 

 Schkuhr figured and described it as D. pubescens, although 

 attributing the name to Swartz. It was not till about 1843 

 that Hooker published the name of D. punctiloba, taking the 

 orthography from Willdenow's Aspidium punctilobum. In the 

 Spring of 1848, Gray's Manual first gave the name D. punc- 

 tilobula, and Kunze followed in July of the same year with 

 the same name. But if a species is to have the name under 

 which it was first referred to its proper genus, then either 

 Willdenow's or Swartz's name is to be chosen. 



The specimen figured was collected on the Peaks of Otter, in 

 Virginia, by Mr. A. H. Curtiss.
