Carex mckittrickensis, the Guadalupe Mountain sedge, is a species of sedge endemic to Guadalupe Mountains National Park in western Texas. It occurs on the sides of steep ravines and also in riparian forests.[1][2]

Description

Carex mckittrickensis is an herb up to 35 centimetres (14 in) tall, spreading by means of underground rhizomes. Its stems are round in cross-section, and covered with reddish-brown leaf sheaths toward the base. Its leaves are thread-like, up to 17 cm (6.7 in) long and less than 1 cm (0.39 in) across. Staminate (male) flowering spikes form at the top of the plant, with pistillate (female) spikes in axils of the leaves.[1][3]

Taxonomy

Carex mckittrickensis is very closely related to the widespread Carex eburnea, but differs in the large size of many of its floral parts.[1] It was described in 1998 by Peter W. Ball of the University of Toronto, and named after McKittrick Canyon in the Guadalupe Mountains National Park.[1]
