They may vary from long (usual) to short-spined. This species resemble in habit with Opuntia invicta.
Stems: Globose or short-cylindrical, light to dark green 5-30 cm tall, 2.5-3.5 cm in diameter.
Ribs: 8 to10
, acute, 8-15 mm wide.
Roots: Fibrose.

Central spines:
Central and upper spines 4 to 10, pinkish to bright red, becoming dirty yellow or grey, spreading, stiff, straight, strongly flattened and angled, erect, 2,5-6cm long. (up to 3 mm in diameter)
Radial spines: Radial and lower spines 7 to12, 1,5-2,5 cm long.
Flowers: Subterminal, infundibuliform, bright yellow, up to 6 cm long and in diameter.
Fruits: Globose, green, becoming red, spiny, drying up but not breaking.

Seeds: 1,2-1,3/1 mm dark/brown black.

Recognized subspecies, varieties and forms:

The 'hancockii' subspecies (regarded by N.P. TAYLOR as only a giant form of Echinocereus maritimus) is characterized by much larger heavily
-spined stems that are 5,5 to 7 cm thick. It forms smaller clumps of up to 30 heads. The color of the spines of 'hancockii' varies from light yellow to black-brown, while young spination in the apex is red in color
The 'maritimus' subspecies grows in great clusters up to over 2 m wide, with hundreds of small short spined stems that are 4 to 7 cm thick.


Cultivation: This plant from Baja California needs warmer winter temperatures, and can resist only occasional light frost, above -2 C. It is sensitive to over-watering (rot prone) and needs good drainage.  Fertilize with a half-strength liquid fertilizer in summer.   Keep absolutely dry in winter.  Needs full sun;
