Facheiroa squamosa is a species of Facheiroa from Brazil.[2]

Etymology

The epithet "squamosa" comes from the latin words squāma meaning scales and the suffix -ōsus meaning "full of", referring to the scales on the ovary.[3]

Description

Facheiroa squamosa is an erect species of cactus, with 18-19 obtuse ribs, 8 radial spines, and 1 central spine almost twice as long as the radial spines. Stems are several meters high, 2.5 to 4 cm in diameter, and have 18 to 19 sharp ribs. Areoles are 6 to 8 mm apart, almost circular, 2 to 8 mm in diameter, and are covered in woolly felt. Radial spines 8, are 5 to 12 mm long, not very sharp, and light brown. The central spine (2 cm) points upwards, having similar characteristics to the radial spines. As the plant ages, the spines gradually fall off or become heavily worn. The white flowers are tubular, 35 to 40 mm long, and 16 to 20 mm in diameter. [4]

Habitat and Ecology

Facheiroa squamosa is endemic to northern brazil, from 370m to 1000m above sea level. Limestone cliffs are where these plants are found.

Facheiroa squamosa grows together with Melocactus, Pilosocereus, Tacinga, and Quiabentia.[5]
