Description: Echinocereus reichenbachiiSN|7595]]SN|7575]] f. albispinus is an undescribed name (n.n.) used in some catalogue to describe a morphological form of Echinocereus reichenbachiiSN|7575]]SN|7575]]. This peculiar plant can be easily tell apart from standard Echinocereus reichenbachiiSN|7575]]SN|7575]] for its pure white spines. This plant is intermediates between Echinocereus baileyiSN|7595]]SN|7595]] and Echinocereus reichenbachiiSN|7575]]SN|7575]] subsp. caespitosus.
Remark: Do not confound this plant with Echinocereus reichenbachiiSN|7575]]SN|7575]] var. albispinus|SN|7605]] (Lahman) L.D.Benson, which is a white form of Echinocereus baileyiSN|7575]]SN|7595]].
Habit: It is a solitary or slowly branching cylindrical shaped cactus with up to 12 branches. It is one of the smaller Echinocereus species.
Stem: Erect, cylindrical or short cylindrical, 7 to 10 cm tall, 2,5 to 8 cm in diameter.
Ribs: 10-19 straight or slightly undulate.
Areoles: 1-6(-10) mm apart.
Radial spines: 20 to 36, straight to slightly curved, held closely against the the ribs of the stems, organized in 2 series, pectinately arranged or nearly so, 5 to 8 mm long, pure white, eventually whit darker tip.
Central spines: Sbsent
Flowers: Beautiful, abundant, scented, intense pink flowers, 5 to 7 cm long (5-7 cm). Flower tube 22-40 × 10-30 mm; flower tube hairs 5-15 mm; inner tepals silvery pink to magenta, usually white, crimson, green, or multicoloured proximally, 23-40 × 5-15 mm, tips relatively thin, delicate; anthers yellow; nectar chamber 2-5 mm.

Cultivation and Propagation: It is sensitive to overwatering (rot prone) needs a very good drainage to avoid rotting, but requires more moisture than true desert cacti to grow and produce flowers, Keep drier and cool in winter. Need full sun. It is very cold resistant from -10° to -25° C (depending on clones) or less for short periods of time. It is a fine plant for a rock garden or container, contrasts well with agaves, yuccas, and low-growing flowering plants.
Propagation: Seeds, also can be grown from cutting as it slowly branches from the base.
