• Distribution:

Trichocereus fascicularis - BR63 = (aka Weberbauerocereus fascicularis - B76)

• Body: Grows in large clusters made up of many slender, erect or ascending branches to 13' (4m.) high.
• Ribs: ~16, low, rounded, separated by narrow intervals.
• Areoles/Spines: Areoles closely set, filled with tawny felt. Numerous spines, at first yellowish to brown; radial spines needle-like, often only .4” (1cm.) long or less; central spines much stouter, to 1.5” (4cm.) long.
• Flowers/Fruit: Slender flowers to 4.25” (11cm.) long, somewhat curved near the base with short perianth-segments, differing from “typical” Trichocerei flowers. Fruit is yellowish to reddish, globular, to 1.5” (4cm.) diameter, splitting open on one side exposing the pulp.
• Distribution: Mountains of southern Peru and northern Chile at about 7500' (2300m.).

• Distribution:

Trichocereus fulvilanus

• Body: Grass green to grayish green stems, branching from the base to 5' (1.5m.) tall; branches to 2.75” (7cm.) diameter.
• Ribs: 8-13, obtuse, notched across half the width.
• Areoles/Spines: Areoles “shortly oval”, to .5” (1.25cm.) with orange to reddish or yellowish felt at first, later brownish black (light brownish in seedlings, then becoming whitish from the base upwards). Spines dark brown at first, then graying. Nine to 12 radial spines, dissimilar sizes, mostly .6” (1.5cm.) to 1.2” (3cm.) long. Two to 4 (to 6) center spines, 1.2” to 4” (3-10cm.) long though up to 7” (18cm.) and stouter, later the upper spines are often finer.
• Flowers/Fruit: Perfumed flowers, apical, to 4.75” (12cm.) long, to 3.5” (9cm.) diameter. Fruit is green, spherical to 1.5” (4cm.) diameter.
• Distribution: Taltal/Chanaral to ElCobre, Chile. Nota bene: Backeberg regards this as nothing more than a form of T. deserticolus.
