Forma 8. glandulare, forma nova, ramis pedicellisque glandulari- 
puberulis vel -pilosis; pilis plerisque rectiusculis patentibus glandulari- 
capitellatis; aliter formae typicae simillimum.—Ecvapor: Prov. 
Chimborazo, vicinity of Huigra, mostly on the Hacienda de Licay, 
August, 1918, Dr. J. N. Rose & G. Rose no. 22,210 (typr, Gr., U.S., 
N. Y.); same locality and collectors, alt. 1525 m., 21 August, no. 
24,078 (Gr., N. Y., U. S.), 28 August, no. 24,078a (Gr., N. Y., U. S.), 
and 6 September, no. 24,078b (Gr., N. Y., U. S.). 
It may be noted that the pappus of this species, both in the typical 
and glandular form, often becomes a beautiful rose-color. As the 
depth of this shade is variable even in different heads of the same 
specimen no taxonomic significance is attached to it.

To this species, originally collected in Costa Rica, there may now be 
added what seems to be a Guatemalan variety. The chief distine- 
tions between the varieties appear to be as follows: ; 
Var. . typicum, arboreum; foliis ovatis lateraliter- symmetries 
vel vix irregularibus in lateribus (argute dentatis) rotundatis _ 
angulatis; ramis inflorescentiaque obscure puberulis.—Costa Rica:
