Drosera hirticalyx

A perennial rosette sundew from the summits of the tepuis of southern Venezuela and the Brazilian border, named for the robust glandular hairs on its calyx. Old plants form upright columns clothed in dead leaves, and it flowers year-round with white petals. It needs cool, very humid, bright highland conditions.
