Easily recognized by the large size and very long cylindrical dense-flowered spike. 
I agree with Mr. Petrie in reducing Kukenthal’s U. pedicellata to the position of a 
variety, for the differences between the two are very slight, and it is only in Stewart 
Island that U. pedicellata has a predominantly red colouration. Kukenthal’s var. 
laxior, recorded by Carse (Trans. N.Z. Inst. xlviii (1916) 240) I cannot treat as more 
than a tall luxuriant form. 
C. B. Clarke, Boeckeler, and Kukenthal all consider that U. australis extends to 
the Sandwich Islands. But Hawaiian botanists treat their plant as a different species, 
giving it the name of U. Lindleyana Kunth. 
The oldest name of the species is Carex uncinata Linn. f. Kukenthal has therefore 
adopted the name of Uncinia uncinata in his monograph of the genus. But Persoon, 
who founded the genus, obtained his generic name by converting the adjective 
‘“uncinata ’’ into the substantive ‘“ Uncinia.” The meaning of the two words is 
identical, and the difference in orthography very small. The name “ uncinata ’? Persoon 
rejected altogether, no doubt from its too close resemblance to Uncinia. It appears 
to me that such a name is in conflict with Rule 55 of the International Rules of 
Botanical Nomenclature, which provides that specific names shall ke rejected when 
they merely repeat the generic name. I therefore retain the name of “ australis ”’ in 
this work.
