Pilosocereus kanukuensis

A columnar tree cactus known from very few collections, on seasonally dry slopes in the Guiana Shield (the Kanuku Mountains of Guyana; Kew lists Venezuela). Grow it like other lowland tropical Pilosocereus: hot, very bright, and never cold, with a drier spell in the dry season. Some authors treat it as part of Pilosocereus oligolepis.
