Specimen examined: Columbia: open savannas of the Rio Dagua,

9. S. PUBESCENS Triana. "Suffrutex erectus; ramis gracilibus, 

 multi-angulatis, minute puberulo-hirtis; foliis inferioribus oppositis, 

 superioribus alternis ovato-lanceolatis acutis dentato-serratis, supra 

 pubescentibus, subtus dense pubescenti-canescentibus, deorsum sub- 

 abrupte in petiolum longum attenuatis, petiolo basi auriculato-am- 

 plexicauli; involucri squamis striatis, dorso tenuiter pubescentibus, 

 exterioribus ovatis, interioribus oblongo-lanceolatis, utrisque acutis; 

 capitulis pedunculatis, laxe corymbosis; acheniis atris, alatis, oblongis, 

 undique decumbenti-pilosi^ 



"Crescit altitudine 1400 metr. inter Tena et El Colegio, in devexis 

 occidentalibus Andium Bogotensium." 



Simsia ■pubesccns Triana, Ann. Sci. Nat. Bot. ser. 4. ix. 40 (1858). 



This species, not since recognized, appears to differ from S. Sodiroi 

 only in its auriculate-amplexicaul petioles and perhaps in the less 

 pubescent scales of the involucre, and may be identical with that 

 species, but in the absence of specimens it seems unwise to combine 

 them. 



39 Described by Hieronymus as stylose, but neutral in the Lehmann plant 

 which he refers to E. Sodiroi.
