(This plant comes in a 3.5" pot. You will receive a very similar plant to the one in the picture. It may or may not be blooming at the time of your purchase. The plant is shipped in its pot to prevent any damage to the roots).
Origin and habitat: is endemic to Lagunillas, Merida state, Venezuela. Several thousand individuals occur in habitat. It occurs in high densities.
Habitat and ecology: This species occurs in flatlands and slopes within inter-Andean dry valley. It is predominantly an out crossing species but partially self-compatible. It is bat-pollinated and bats and birds disperse the seeds. The inter-Andean dry valleys represent an important reservoir of plant and animal species adapted to xeric conditions. Given the current isolation of these dry enclaves, they may represent important areas of speciation and endemicity. It is very probable that each enclave contains populations undergoing the speciation process, and some of the columnar cacti could represent currently unrecognised endemics. This species is listed as Endangered because it has a very restricted distribution (extent of occurrence is approximately 262 km2) and it is known from only one location which is under high pressure from urban and agricultural development.
Pilosocereus tillianus is a columar cactus composed of slender, tubular shaped branches up to several metres tall. Pilosocereus tillianus looks very attractive when young.
