Spruce says that this is very slender and brittle in the flowering portion, 

 at p. 3, stated how very rarely this plant has been found in flower. Ruprecht states that he 

 had seen but a single spicula ; and Nees states, in Marlins's ' Flora Brasil.,' that there was 

 no specimen in any herbarium he had access to. Kunth states that his description and 

 figure were taken from a specimen presented hy Humboldt, who says that the plant II 

 very abundant on that part of the Orinoco which is below the cataracts. I have quoted 

 Trinidad as a locality on the authority of Grisebach. The very long spicuhe appear to 

 keep this distant from all other species. The drawing in the Plant. Mqum., which u 

 not a good one, is more like the following species than any specimen I have seen of 



G. latifolia.
