Nolina interrata is a dioecious (separate male and female plants) perennial forming clusters of rosettes from underground rhizomatous platforms (rootlike horizontal stems).
Nolina interrata is distinguished from the other Nolina species that occur in California by its lack of aerial stems, rosettes with 45 or fewer finely serrate leaves, and flower stalks under 1.6 m (5 ft) tall.
Nolina interrata is covered by the MSCP based on conservation of 100 percent of the McGinty Mountain population, 90-100 percent of the Sycuan Peak, and 80-100 percent of the Dehesa Peak population under this plan (City of San Diego 1997).
Nolina is a genus of plants in classified variously in the Nolinaceae, Agavaceae, Ruscaceae, or Asparagaceae, depending upon how those families are circumscribed.
It constitutes a group of tropical xerophytic plants, with the principal distribution being in Mexico and extending into the southern United States.
Some botanists have included the genus Beaucarnea in Nolina.

This Nolina is also known as sacahuista and is native to Arizona, New Mexico, Texas and Mexico.

The igneous soils along the arroyos and the limestone rocky clay of grassy hills, from 2100 to 7500 feet in the Trans-Pecos and Northern Mexico provide a home for the foothill nolina.
The leaves are strongly serrulate (minutely toothed) and usually have numerous woody fibers which appear to be irregularly torn.
Additional Comments: Nolinas are polygamo-dioecious, that is: they usually have male and female flowers on separate plants, but each plant also has a few perfect flowers (male and female flower parts on one flower).
Name – Nolina, pronounced NO-lee-na or Beaucarnea recurvata, pronounced bow-CAR-nee-a.
Its common names are ponytail plant or elephants foot.
Description - Nolina has thin arching leaves sprouting from the top of a fat or long woody stem and a bulbous base that looks scaly like an elephant's foot.
Nolina recurvata risk assessment(Site not responding. Last check: 2007-10-30)
AB: In vitro culture of B. recurvata [Nolina recurvata ] shows promise; in several years' trials at Melle, 95% success was achieved, compared with only 10% for vegetative propagation from shoots.
Plants with up to 4 shoots could be produced after about 9 months from the start of culture.
We oberserved seed of the same Nolina plant germinated within 7 days and 2 months later seeds continued to germinated.
Growth Habits: Shrub, up tot 15 feet high (4.5 m) 6 to 10 feet spread (1.8-3 m); short trunk; stiff leaves with small teeth on their margins, 2 to 3 feet long (60-90 cm), up to 0.8 inch wide (2 cm)
One of the largest Nolinas, it is salvage restricted and harvest restricted in Arizona.
Flower spike, up to 6 inches in diameter (15 cm), 4 to 10 feet long (1.2-3 m), with dense clusters of tiny cream flowers, in spring (April to June).
Dehesa Nolina [Nolina interrata Gentry](Site not responding. Last check: 2007-10-30)
Habitat: Open Southern Mixed Chaparral and Chamise Chaparral are the preferred habitats of this distinctive shrub.
Near the Dehesa School a series of fires have left stands of this Nolina in a disturbed annual grassland.
Status: The Dehesa Nolina populations in San Diego County are presently stable, but are being slowly impacted by the clearing of lands for isolated homesites.
