Wurdack 35578 (NY). Paratypes: data as above, Maguire & Wurdack 35573; same 

 locality, November 23, 1953, Maguire, Wurdack & Bunting 36343. 



Distribution. Known only from the type locality, Sabana Venado, where it is a 

 frequent shrub about thicket and woodland margins. 



Section 3. Connellia Maguire & 7/urdack, sect. nov. 



Capitula solitaria, terminalia, majuscula 20-40-flora; receptaculo epaleaceo 

 vel paucipaleaceo; filamentis in sinibus affixis; achaeniis prismaticis; annulo 

 deficienti; pappo 3-5-seriato, setis filiformibus; foliis non reticulatis. 



TYPUS: Stenopadus connellii (Baker) Blake. 



6. Stenopadus connellii (Baker) Blake, Bull. Torrey Club 58: 490. 1931. 



Stiff tia connellii Baker. Trans. Linn. Soc. II. 6: 40. pi. 8. 1901. 



TYPE: summit of Mount Roraima, 8600 feet, McConnell & Ouelch 661 Kew. 



Distribution. Presently known only from Mt. Roraima and Chimanta-tepui, 

 occurring in cumbre woodlands at 2000-2300 m alt. 



Only a single collection from Mt. R.oraima {Tate 439, NY) has been available 

 for this study. The corolla-tubes of the specimen reach a length of nearly 20 mm, 

 whereas the corollas of the much more amply represented Chimanta population 

 develop tubes only 12-14 mm long. This may represent a racial difference.
