    Tipo y Observaciones

    Material Tipo: Holotype: CHILE: Coquimbo, Dpto. Illapel, Hacienda Cuncumén, cajón de los Pelambres, 3000 m, suelo pantanoso, 9–12 Jan 1932, Looser 2141 (GH-00101841 digital image!).
    Observaciones: Iconography: Figures 2P, 3P. See additional figures in Wheeler (2009: 331, fig. 296). Etymology: From the Greek pleion, many, and neuro, nerves, ‘many nerved’ referring to the nerved utricles of this species. Notes: The name Carex pycnostachya Desv. has been often listed as a synonym of C. nebularum. However, after the examination of the digital image of the selected lectotype specimen, spike and utricle dimensions point to C. pleioneura as a much better match. This also agrees with the geographical location of the types of the two names. The illustration associated with the protologue shows a nerveless utricle. However, the protologue also specifies that the utricles are nerveless but before ripening (“Utrículo sin nerviosidades antes de la madurez”). We confirm that the selected lectotype specimen bears unripe utricles, but even so, some nerves are observable in two of the utricles in the envelope. This agrees with our identification of the specimen as C. pleioneura. Selected additional references: Wheeler [(1987) description, (1996b) key, (2009) description].
