742 REPORT OF NEW JERSEY STATE MUSEUM. 



CHONDROPHORA Nuttall. 



Chondrophora nudata (Michx.). Rayless Goldenrod. 



Chrysocoma nudata Michaux, Fl. Bor. Am. II. loi. 1803 [Carolina]. 

 Chrysocoma virgata Nuttall, Gen. II. 137. 1818 [New Jersey]. 

 Bigelovia nudata Willis 32. — Britton 133. 

 Bigelovia nudata var. virgata Britton 132. 



Tlie occurrence of this species in the State seems to be based 

 upon the statement of WilHs that it is found at Blue Bell, Mon- 

 mouth Co., and of Gray that it occurs in "low pine barrens." 

 Both are based in all probability upon Nuttall's record of C. 

 virgata, which they regarded as identical with nudata. 



The form known as virgata was described by Nuttall from 

 "the borders of swamps in New Jersey near the sea coast." He 

 adds that it is "nearly allied to C. nudata, but distinct, and resem- 

 bles more Solidago temiifolia, with w^hich it might easily be 

 confounded." Notwithstanding the fact that New Jersey is the 

 type locality for virgata — in fact the only locality mentioned — the 

 name is used, probably rightly, for a southern plant in Britton 

 and Brown's Illustrated Flora and other works. The type 

 labelled "New Jersey" is still preserved in the herbarium of the 

 Philadelphia Academy, but doubtless the label is the result of a 

 slip of memory on Nuttall's part. For a further discussion of 

 the probability of Nuttall's type coming from elsewhere cf.
