- Abstract
Calathea neillii H. Kenn. and Calathea fredii H. Kenn., both endemic to Ecuador, are described as new. Both species are distinguished by their inflorescences of bright red, distichous, bracts. They are most similar in aspect to Calathea trianae L.B. Smith & Idrobo from Dept. Nariño, Colombia. Calathea neillii differs from C. trianae in the narrowly ovate to narrowly ovate-elliptic vs. elliptic leaf blade (length:width ratios 5.87-6.93:1 vs. 3.55-4.58:1), the shorter peduncle (1.1-1.4 vs. 10-14.6 cm), and the relatively broader inflorescence (length:width ratios 2.4-2.9:1 vs. 6.0-7.33:1). Calathea fredii differs from C. trianae by the strongly corrugated vs. smooth leaf surface, narrowly elliptic vs. elliptic leaf blade (length:width ratios [4.8-]5.24-7.45:1 vs. 3.55-4.58:1), and the purple and white vs. yellow petals.
