Nota, J. Holoschoenus gehört unverkennbar in die Verwandtschaft des J. lampocarpus, 
nähert sich aber durch die Fruchtform dem J. acuminatus und prismatocarpus. Von dem 
letzteren unterscheidet er sich durch starreren Wuchs, die größeren Köpfe, die kantigen 
Blüten und die Sechszahl der Staubblätter. Die Vereinigung von J. Holoschoenus mit 
prismátocarpus, welche BExtnam in der Flora australiensis vorgenommen hat, halte ich 
für ganz unnatürlich.
