 bus, venis reticulatis, supra prominulis, subter prominentibus; petiolo 3-5 mm 

 longo; capitulis solitariis terminalibus majusculis hemisphaericis, multifloris, 

 radiatis; pedunculis 3-5 cm longis; bracteis subtendentibus 2-jugis, foliaribus, 

 glabris, ovatis, acutiusculis, 5-8 mm longis; phyllariis 3-seriatis, exterioribus 

 late orbicularibus oblongis, ca. 8 mm latis, 10 mm longis, corpore indurato, 

 marginibus scariosis, interioribus ca. 12 mm longis, angustioribus sed plus late

 apice rotundato vel late obtuso, eroso, ca. 8 mm longo; corollis 5-6 mm longis,

TYPE: shrub 4-8 dm high, radiate, but ligulate flowers post-mature and lost, 

 occasional in scrub bush, Mesa Ridge at 2000 m alt., Cerro Ilu-tepul, Guayana, 

 Venezuela, March 23, 1952, Maguire 33550 (NY). Known only from the cumbre 

 of Ilu-tepui. 



Galea lucida is to be interpreted as derived from the polymorphic C. lucidi- 

 venia. The Ilu-tepul plant has solitary massive heads with 75-100 florets, and 

 suborbicular leaves. Both of these are mere quantitative expressions of charac- 

 ters variable in C. lucidivenia, but form and induration, and lack of vittation of 

 • the involucral bracts of C. lucida are strikingly distinctive from those of C. 

 lucidivenia, which are strongly vittate.
