Scandent shrub, 3 m. or less in height; stem and branches 

 terete, striate, tawny tomentulose; leaves alternate, petiolate, 

 lanceolate or elliptic-lanceolate, 3-10 cm. long, 1.5-3 cm. broad, 

 usually acuminate, acute, entire, sparingly tawny puberulent 

 in the early stages, more or less glabrate, pale green, the median 

 nerve and veins immersed and persistently puberulent above, 

 somewhat prominent beneath; inflorescence a terminal tawny to- 

 mentulose panicle; heads subdiscoid but heterogamous, about 8 

 mm. high, disposed in glomerules; involucres narrowly campan-

female flowers 3-5, much reduced, corollas nonligulate, slender, 

 tubuliform, about 4 mm. long, subequally 5-dentate; flowers of 

 the disk 10-12, hermaphrodite, corollas tubular-campanulate,

 Y. Bot. Gard. Herb., type; U. S. Nat. Herb., Gray Herb., and 

 Mo. Bot. Gard. Herb.). 



The relationship of this species seems to be with S. Jelskii 



Hieron. from which, however, it differs in having persistent to- 



mentose branches, tawny puberulent leaves, and rayless pistillate 

 flowers.
