ILLUSTRATIONS OF THE GENUS CAREX. 
lin. latum, ovale, .basi product urn, apice annulatum, annulo 
basin styli incrassatum cingente, postice costa media modice 
elevata (rudimento anguli) notatum, stramineum. 
I have never seen an authentic specimen of Thunberg’s C. re¬ 
match, nor of the C. gibba of Wahlenberg, neither of whom refer to 
the stigmata, though Willdenow says it has two. When exa¬ 
mining the Japanese plants of Morrow, which were described in 
the second volume of Perry’s ‘ Expedition to Japan,’ 1 was led 
to infer, from the three stigmata and the annulated achenium, 
that the plant before me could not be safely referred to C. gibba, 
and I described it under the name above quoted ; but, on recon¬ 
sideration, I am inclined to consider it as Wahlenberg’s plant. 
The margins of the perigynium are rather acute than winged, as 
Wahlenberg sa} r s, “ marginibus extenuatis They are more or 
less (sub lente) very delicately serrulate, especially at the rostrum. 
The posterior central angle of the achenium is not prominent. I 
know of no immediate affinity with this species, though in habit 
it has a resemblance to the C. alia of Java.

I have only seen this species in Herb. Nuttall.

Schkuhr figures the perigynium more nerved than I have ob¬ 
served it. Gaudiu describes the female spieuhe 4-6. I have 
found the smaller number only. 
The specimens figured are from Germany.
