 maguo, subgloboso, appeudiculis tenuibus: ovario turbinato, obsolete 6-costato, 

 pulverulento, vertice subconcavo, reticulato ; stylo breviter conico, 6-sulcato ; stig- 

 mate niveo 6-radiato coronate. In Venezuela et BrasiHse confinibus : v. s. in herb. 

 Hooh, Eio Casiquiare {Spriicet sine num.), Eio Uranacud {Spruce, 1933). 



A tree 20-30 feet bigh, growing by the side of rivers, and apparently confined to the 

 upper tributaries of the Rio Negro ; it is near G. speciosa, differing, as Dr. Spruce well 

 observes, in tbe thinner texture of its leaves, a less number of nervures, in their more 

 spatiiulate form, rounded on the summit, decurrent at base, on a shorter petiole, more 



r 



numerous flowers on longer and more slender pedicels, bracteolated above the middle, 

 the calycine limb more distinctly and acutely lobed. The leaves arc 17-25 in. long, 3- 

 in. broad, on a petiole J-J in. long, with about 24 pairs of nerves, at a distance from 

 each other of 10 lines : the raceme, apparently torn from tlie trunk, has a peduncle 1-2 

 in. long, pedicels 1^-2 J in. long ; limb of calyx 1 J line long, 7 lines in diam. ; the petnls 

 2-2J in. long, f-1 in. broad ; the flower expanded is 4J-5 in. in width. I have corrected 

 the locality given by Spruce, the river properly spelled is ITaranacua (not Uanauaca) ; it 

 is near Carvocira.
