Bigelovia nudata var. virgata Torr, & Gray, PLN. A. 22232. 1812, 
Chondrophora nudata virgata Britton, Mem. Torr, Club, 5:8317. 1894, 
Nearly allied to the above by its inflorescence and the morphological characters 
of the flowers, but differing widely in its habit of growth, range of distribution, 
and foliage, and deserving to be recognized as a distinet species. ‘The many-headed 
rootstock produces numerous stout shoots crowded with the filiform leaves, forming 
dense tufts. In the Alabama specimens and others from Jouisiana all the leaves 
are filiform. It is only ina specimen trom ‘Vexas that a tendency can be observed 
to the development of a wider leaf blade. These linear lanceolate leaves found in 
young shoots are not over ||. inch wide, acute, channeled toward the base and with- 
out lateral nerves. 
On comparison with Nuttall’s type in the herbarium of the Academy of Science, 
Mr. Thomas Mechan tinds the Alabama plant identical with Nuttall’s specimen, on 
which the radical leaves are wanting. Nuttall says: ‘Nearly allied to Chrysocoma 
nudata, but distinct, and resembles more Solidago fenuifolia, with whieh it mingles 
and is easily confounded.”
