|Species:|| Montia linearis (Douglas ex Hook.) Greene|
Annual herb from a fibrous root; stems ascending to erect, usually solitary but sometimes several, branched or unbranched, 5-20 cm tall.
Basal leaves lacking; stem leaves several, leaves are alternate throughout and narrow.
Inflorescence consists of loose terminal or axillary racemes, bearing 5-12 flowers on slightly recurved stalks.

Moist to dry habitats in lowland to foothills.
Seed sample from: 2011
Average Measurement: 2.2 x 2.2 x 1
Measurement Range: L: 2 - 2.5, W: 2 - 2.5, D: 0.9 - 1.1
Shape: Seed lenticular in shape.
Color: Hilum scar is white, surrounded by a ring of brown. Seed is dark red to black.
Surface: Seeds are papillose with some small ridges around the surface edges.
Could be confused with: Caladrinia ciliata
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.
