80 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



This species is related to 8. theaefolius Benth., but differs in 

 having the branches and inflorescence distinctly tawny and 

 densely hispid pubescent, in having the lower leaf-surface more or 

 less puberulent, especially on the midrib, lateral nerves and re- 

 ticulated veins, and in the somewhat shorter involucre and small- 

 er flowers. 



Senecio Chinogeton Wedd. forma macrocephalus Hieron. in 

 Engl. Bot. Jahrb. 19:64. 1894. 



Colombia: in bushy mountain valley, Rio San Cristobal, near 

 Bogota, Department of Cundinamarca, alt. 3000-3300 m., Sep- 

 tember 20-26, 1917, Pennell 2047 (N. Y. Bot. Gard. Herb., Mo. 

 Bot. Gard. Herb., and U. S. Nat. Herb.). 



The specimens under Pennell's No. 2047 show only the com- 

 plete inflorescence with mature, discoid, nodding heads, and a 

 few of the uppermost stem-leaves. From the original descrip- 

 tion of the above species they would seem to be conspecific and 

 probably represent the form "macrocephala", briefly character- 

 ized by Professor Hieron ymus.

Mr. Bang's No. 1240 was taken to represent Senecio culcitioi- 

 cles Schz. Hi])., which it resembles habitally, and distributed as 

 that species. The specific name, however, was inadvertently 

 written on the label as "calcitoides," and the plant was referred 

 to in Mem. Torr. Bot. Club 6:65. 1896 as "Senecio culcitroides 

 Wedd." The heads of the Bang plant are distinctly radiate, not 

 discoid as in L. culcitioides Schz. Bip. The discoid heads and the 

 very broad, conspicuous, almost glabrous midvein on the lower
