Discussion
Carex defexa var. boottii is sometimes included in C. rossii. The varieties are said to differ in the degree of spreading of the rhizomes; var. boottii is more cespitose in habit and has stouter rootstocks than var. deflexa. That character varies considerably within each variety, and may be dependent on the compaction and particle size of the soil in which a plant is growing. These taxa clearly form a complex that requires further study.
The name Carex brevipes was first proposed by W. Boott (in S. Watson 1876–1880, vol 2, p. 246) but then withdrawn (p. 485), so was not validly published by him. Subsequent authors used the name, attributing it to W. Boott. It was validly published at species rank by K. K. Mackenzie (1931–1935) and at varietal rank by L. H. Bailey.
