 the base of the locules, 2 or 1 in each of the 3 locules, totaling 5-3 ovules per 

 ovary; fruit unknown.

Though very similar to 8. fulvovirens, it seems prudent to continue to recog- 

 nize 8. juninense as a distinct species until more adequate collections have ac- 

 crued. The type collection is most distinctive (in this section of the genus) for 

 its exceptionally wide spathe, and its stout spadix borne on an elongate stipe. 

 Other Peruvian collections cited are somewhat anomalous, and were annotated 

 juninense vel aff." Cuatrecasas 10665 was similarly annotated; its elliptic 

 leaf-blade is acute at the base, and its spathe is narrower than that of the typical 

 form. The small amount of material available precludes a knowledge of the 

 natural variation of this species, yet these collections may represent a single 

 taxon. 



The Cordillera Oriental forms a geographic barrier in Colombia between S. 

 fulvovirens and 8. juninense. These two species are very similar, but the spathe 

 is somewhat wider and there is a small reduction in the number of ovules per 

 ovary in 8. juninense. It is easily separated from 8. floribundum by its much 

 greater size.'
