MARYLAND WEATHER SERVICE 3S5 



of the Northern States and Canada (New York, 1901). On tho 

 other hand several species have heen omitted which have been re- 

 ported from the State, for example Steuantliium robustum, noted 

 in Ward's List for the vicinity of Washington has not been seen by 

 any recent collectors and may be considered as having been exterm- 

 inated, if indeed not reported in error. Maryland is also reported 

 as being the limit of range for Yucca filamentosa and Agave ameri- 

 cana. While these species have been seen growing in the southern 

 Eastern Shore they were in both cases too near to dwellings to be 

 regarded as undoubtedly indigenous. In like manner the numerous 

 Pine Barren species mentioned in Chapter II. must be omitted from 

 the flora of Maryland although they occur both to the north and the 

 south of the State and are tacitly credited to it in general statements 

 of their range. 



The total number of species and varieties in this List is 1400, and 

 as stated in Chapter II. the total flora when fully collected will 

 probably approach 1900 species.
