dency in this organ, though the contractile action of it seems to 
be limited to the panicled group to which G. polystachya and G. 
Hartwegii belong. 
In Tab. CCCOXCII. I have given figures of what may be G. 
cladostachya, Wahl., the middle or lower spikes of which are 
always geminate, the perigynium smaller, with a shorter generally 
straight rostrum, and commonly quite smooth, or with only a 
scattered tooth at the sides or in the rostrum. The scales are 
sometimes suborbicular or broadly ovate-obtuse, or the upper 
ones subacute, or they are all ovate, acute, more or less striate, 
the lower ones generally scabrous.

More fully developed specimens will necessarily lead to a mo¬ 
dification of the character of this pretty species, and suggest its 
affinities; but any example of the genus from South America is 
too interesting to be passed over. The richness of its flora has, I 
suspect, led many who have explored it to neglect the Gyperacece , 
for Garices must abound in the higher regions. I have figured 
the specimens from Mr. Spruce, for which I am indebted to Mr. 
Bentham.

The slender weak culm, narrow flaccid leaves, the terminal 
spicula male or male at base, the lower ones female, the more 
convex anterior surface of the perigynium with the orifice pro¬ 
longed downwards, distinguish this delicate species from those 
allied to it in habit. The perigynium varies in form, and espe¬ 
cially in the attenuation of the rostrum, which is occasionally 
much shorter than in the figure given of it. 
I agree with Vahl in referring G. ursina to a depauperate form 
of 0. glareosa (vide Drejer, Rev. 21). Dries was inclined to refer 
it to C. bicolor; but the subacute (not roughly granulated) peri¬ 
gynium with the anterior prolongation of the orifice, the ferru¬ 
ginous colour of the squama with the central nerve generally of 
the same hue, and the hyaline margin, ally it to G. glareosa.
