Lemaireocereus montanus Britton & Rose
Publication The Cactaceae 2: 97 (1920).
"16. Lemaireocereus montanus sp. nov.
Tree-like, 6 to 7 meters high, with a definite smooth trunk 1 meter long or more, with few branches, at first spreading, then nearly erect; ribs few, usually 8, prominent areoles 1 to 1.5 cm. apart, large, filled with short brown wool; spines few, 6 or less, pale in color, rather stout, one of them longer, sometimes 3 cm. long; flowers 6 to 7 cm. long, opening during the day; outer perianth-segments purplish; scales on the ovary ovate, 4 to 6 mm. long, imbricated, acuminate, with erose margins.
This species was found well up on the side of Alamos Mountain, associated with Lemaireocereus thurberi, but usually at a higher altitude than that at which that species is generally found. It differs from L. thurberi in its habit, number of ribs, armament, and flowers. Like L. thurberi it has brown areoles, which are not found in any of the other species except L. queretaroensis of the table-land region of central Mexico.
Collected by Rose, Standley, and Russell above Alamos, Mexico, March 18, 1910 (No. 13039)."
