The species does not appear to have been collected much 

 below the Amazon in Brazil, but there are specimens at Kew col- 

 lected in the Upper Amazon, Traill 1394, and Para, Spruce 2/ 

 and 5<5p. We have seen Poeppig's plant (cotype of Lomariopsis 

 phlebodes) at Vienna and it does not appear to be separable 

 from the widely distributed species as listed above. This species 

 and S. erythrodes of Southern Brazil are united under a distinct 





name (noted above) by Chi
