Taxonomic Notes on Carex (Cyperaceae) of Austral South America

The name Carex poeppigii (sect. Echinochlaenae) is validated and a new combination in South American Carex, C. vixdentata (sect. Spirostachyae), is made here. Also, the taxonomic status of C. aueri is discussed, and this name is placed in the synonymy of C. reichei (sect. Arenariae).

Lemma 2.1. Let F be a field, let E = F (α) be a simple extension of F , where α is algebraic over F and f = irr(α, F, x), let ψ : F → K be a homomorphism from F to a field K, and let L be an extension of K. If β ∈ L is a root of ψ(f), then there is a unique extension of ψ to a homomorphism φ : E → L such that φ(α) = β. Hence there is a bijection from the set of homomorphisms φ : E → L such that...
