Baldwinia 



nov. 



Stem furrowed, erect, 6-8 dm. tall, simple or with one or 

 two erect branches : leaves alternate, ascending, linear-spatulate, 

 gradually diminishing in size toward the summit of the stem ; the 

 lowest 10-12 cm. long by 3-4 mm. wide: heads 1-3, terminal: 

 ligules of the rays spatulate, 3-4 cm. long, 3-4 mm. wide, 2-3- 

 toothed at the apex, pale yellow : disk-corollas dark purple : pap-

near relative, by its dark-purple disk, longer and narrower leaves, 

 and usually longer and fewer rays. Its aspect in the field is so 

 different from that of B. unifiora that I was not certain of the genus 

 until I examined the achenes several weeks after collecting the 

 specimens. In the living plant the rays are decidedly paler than 



ifli 



specimens. 



Collected in moist pine barrens, Tifton, Berrien county, at 340 

 ft. altitude, about 4: 1 5 p. m. on September 19th (no. 662). Accom- 

 panied by such species as Woodivardia Virginica, Eriocanlon decan- 

 gidare, Sarracenia flava (no. 663), S. psittacina (no. 666), Aeschy- 

 nomene Virginica, Eryngium integrifolium Lndovicianum, Oxypolis 

 filiformis (no. 659), O. ternata (no. 666), Mesosphaerum rugosum, 

 Viburnum nudum, Coreopsis angustifolia (no. 661), and Mesadenia 

 lanceolata (no. 664), which is rather a different association from 

 that in which I have found B. unifiora. 



I find no specimens similar to mine in the U. S. National Her- 

 barium or the herbaria of Columbia University and the New York 

 Botanical Garden ; but it is possible that this species has been col- 

 lected before. Dr. Chapman, in his Flora, under the head of B. 

 unifiora, says : " Dr. Curtis finds a form with the disk flowers dark 

 purple," and this would seem to indicate the occurrence of this 

 species in North Carolina. It should be looked for in the coastal 

 plain of that state, as well as in South Carolina. 



Rafinesque has described a Baldwinia bicolor* "found by Le 

 Conte in Florida or Georgia," which I thought at first from his 

 specific name might be my plant ; but certain clauses in his de- 

 scription, such as " with white rays and yellow disk " and " stem 

 Pedal, leaves uncial," would seem to exclude my B. atropurpurca, 



New Fl. N. A. 4 : 73. 1836.
