SPATHIPHYLLUM

tilla, Honduras, which I refer to 8. blandum, though indeed it is aberrant for 

 that species. 



In synonymy under this species Engler listed S. lanceolatum C. Koch and 

 Massowia lanceolata C. Koch. The present study indicates that these names are 

 synonyms of 8. cochlearispathum (which see). 



Engler described var. brevifolium of S. friedrichsthalii based upon a collec- 

 tion from southwestern Colombia (Lehmann 2751, deposited at Berlin, and 

 presumably destroyed). Study of the relatively small amount of material avail- 

 able from this large region, while more than Engler had for examination, offers 

 little justification for a named variety.

Type collection: F. M. Liebmann s.n. (here designated by me M41A), "in 

 sylvis umbrosis circa Mirador," Veracruz. Mexieo, Nov 1841 (lectotype C, isotype 

 [designated by me M41B] C). I cannot accept as duplicates of the lectotype the 

 two sheets of Leibmann s.n. (designated by me M41C and 3I41D). 



Distribution : Rainforests of the Caribbean coast of Mexico, in Veracruz, 

 eastern Oaxaca and Chiapas, Tabasco, and at cenotes in Yucatan.
