Very closely related to G. MerrilUi, from which it differs especially in its 
primary and secondary spathes, wliicli are prickly in 0. Merrittiemus and smooth 
in G. MerrilUi. It is also a near ally of G. Zollingcri% which, however, has quite 
differently armed leaf-sheaths.

« This species is closely related to G. Moseleymnis Becc, ami Ix'longs to Croup 
XV, of my Monograph, characterized as follows: "Leaves prolonged into a h.n*; 
and clawed cirrus. Leaf -she at lis not flagclliferous. Spadices usually shorter than 
the leaves, not or slightly flagclliferous at the apex, f^pikelets not stalked, 
inserted near the mouth of their respective spathes. Fruiting perianth pedicelli- 
form or almost explanate. Seed with mor6 or less superficial intrusions of the 
integument or distinctly ruminate, emhryo basilar or slightly shifted to one side."
