Hymenopappus radiata, u. sp. Perennial from a long slender root, 1^ feet high, 

 brauchitig at base Hoccose-tomentose becoming somewhat glabrate above : leaves 

 mostly radical, 1 to 2 pinnate into narrow, linear segments: heads corymbose on 

 peduncles 1 to 2 inches long: involucre bracts broad, little or not at all pet- 

 aloid ; rays about 5, white, 6 to 7 lines long: disk-flowers nnmerous ; proper tube 

 short, about i line long; throat swollen, campauulate, about 1 line long; lobes 

 short, acute, about one-third the length of throat; anthers but not the iila- 

 monts exs(^rted : akenes 1^ to 2 lines long, obpyramidal, 4-angled with a delicate 

 intermediate nerve, glabrous or a little pnberulent: pappus of numerous very 

 short paloiB, — Common in low rich bottoms under pines and oaks. Willow 

 Springs. July 5 and 6. No. 615. 



This species difters from all other species of Hymenopappus in the presence of 

 ray-flowers, but in other respects corresponds with this genus. Its habit is per- 

 haps more like H.JiU/olius, but the akenes and pappus are more like H. Jiaresceiia. 

 Although it seems undoubtedly a Hymenopappus, yet in all its external appear- 

 ances, including the rays, it resembles Leucampj/x ; the disk-llowers, akenes, and 

 pappus are also similar. It has been a puzzle to me to separate this species 

 clearly from L. Neicberryi, and it is questionable whether they ought not to go 

 together and be placed under Hi/menopappus. The following are the slight dif- 

 ferences I note between the two: In H. radiata the pappus is not so deciduous, 

 the proper corolla tube is shorter, and the style-branches a little thicker and not 

 80 papillose. The absence of the bracts on the receptacle seems to be the only 

 reliable character separating the two genera.
