92 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 12 



KEY TO SPECIES 



1. Plants small, reaching 1.5 dm, the segments without any costa 

 and with strongly crisped margins S. ecuadoreanum 



1. Plants exceeding 2 dm in height 2 



2. Blades without a costa, the segments 1.5-3.0 cm broad, the plane 

 margin coarsely and sparingly sinuate dentate . . . S. veleroae 



2. Blades showing a rudimentary costa near the base, the segments 

 4-6 cm wide, with entire to sinuate, sometimes slightly crisped 

 margins S. Schmittii 



Spatoglossum ecuadoreanum n. sp.^'^ 

 Plate 14, Fig. 2 



Plants exceeding 15 cm in height, light brown and bushy, the base 

 slightly expanded, the lower axis smooth, irregularly forked, above flat, 

 the branching irregular, in the upper divisions foliaceous, firm, irregularly 

 dichotomously divided, broadly spatulate with rounded ends, the margins 

 coarsely sinuate and very much crisped. 



These plants resemble S. veleroae j but the blades reach their greatest 

 width veiy near the end, are not definitely serrate, and are extremely 

 crisped. They may be compared with S. crispata Howe (1914, p. 68, pi. 

 26), but the lower divisions are more stalklike, the terminal segments 

 shorter, do not taper distally, and are much more crisped than his plants.
