The previously unrecognized species 8. matudae is distributed along the 

 Pacific slope from southernmost Mexico to El Salvador. The long-attenuate pistil 

 of the Chiapas and westernmost Guatemalan material is similar to that in the El 

 Salvador collections. In Guatemala, however, the style exhibits various forms 

 from attenuate to rostellate, and certain specimens (e.g., J. D. Smith 2241, 2790) 

 show a relation to 8. brevirostre, especially in the form of the style. 



The type collection of S. matudae was selected from the Chiapas material, and 

 the species was named to honor its collector, Eizi Matuda. 



Distinctive features of 8. matudae are the broadly obtuse base of the leaf- 

 blade, the relatively long geniculum, and the constriction of the pistil between the 

 ovary and the style. The leaf-blade is widest below the middle, and is typically
