==Description==  
''N. squarrosa'' is a prickly, taprooted, hairy annual with a distinctly skunky smell.  Plant is simple or branched, with erect stems, and up to 40 cm tall. Leaves are alternate, firm, and spiny, up to 6 cm long, and pinnately lobed. The flowers are pale to deep blue, with half united sepals that form a short tube with wax-papery intervals between the sharp wointed lobes that are 8 -14 mm long. The flower has 5 fused petals that form a 9-12 mm tube that spreads into lobes. The flowers form large, dense heads with leafy bracts. Fruits are three chambered, elliptical capsules containing 6 - 9 seeds per chamber.

Habitat

Open places, dry to moist meadows, usually at low elevations. Grows in sandy, loamy, or clay soils, and tolerates basic, neutral, or acidic soils. Soil moisture level can be dry to moist, but must drain well. Navarretia squarrosa is shade tolerant, prefers sun.


Uses

Navarretia squarrosa has an edible seed when it is parched, ground into a powder and eaten dry. [94].

seed

Abbrevition: NASQ

Seed sample from: 2011

Average Measurement: 0.9 x 0.6 x 0.5

Measurement Range: L: 0.75 – 1.1, W: 0.5 – 0.75, D: 0.4 – 0.5

Features

Shape: Seeds tapered to almost pointed at hilum ends. Body of seeds sometimes not completely filled out – some concave dents. Hilum is pinched looking in some.

Color: Seeds reddish brown, hilum usually slightly lighter in color, but not very conspicuous.

Surface: Seeds covered in wrinkly pitted pattern. About 30 – 40 medium sized pits visible on one seed face. Seeds slightly rough looking, and somewhat lustrous.

Latitudinal Cross Section: elliptical NASQ lat.png

Longitudinal Cross Section: elliptical NASQ long.png

Basic Explanations and Assumptions:

The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.

Measurements included are the mean average for each measurement of ten separate seeds.

All measurements in millimeters unless otherwise noted.
