- ense (Latin), denoting origin. From Bolivia.

Taxonomy.

This species is very similar to Cortaderia nitida , with which it shares the (usually) non-lacerated, entire leaf sheaths and the shape of the lemmas, as well as largely similar leaf anatomy. However, neither chloroplast nor nuclear genome indicates such a relationship for Cortaderia boliviensis ( Pirie et al. 2009). It differs by the horizontally shattering sheaths. More inconsistent differences are in the indumentum of the floret, with the callus indumentum of Cortaderia boliviensis being shorter than in Cortaderia nitida . Lyle (1996) diagnosed Cortaderia boliviensis against Cortaderia bifida , under which it was originally described as a variety by Henrard in 1921. Mostly it is very different from Cortaderia bifida : the latter has much longer lemma setae and the basal sheaths are lacerated and not shattered. The type collection, however, is easily confused with Cortaderia bifida due to the long awns and setae, and somewhat fragmented leaf sheaths. The leaf anatomy is also quite different.

The leaf anatomy (Fig. 3E View Figure 3 ) is like that of Cortaderia nitida , with adaxial grooves and a well-developed abaxial collenchyma layer. There are differences in detail, and wider sampling may well indicate that this is within-species variation.
