Montia linearis, or narrow-leaved montia is a flowering plant in the Portulacaceae family. It is sometimes called miner's lettuce, which is a name often applied to many montia genus plants because of their edibility. Synonym: Claytonia linearis

Description
M. linearis is an herbaceous, low annual that is somewhat succulent. Plants are several branched and between 5 and 20 cm tall. Leaves are alternate and narrow, 1.5 - 5 cm long. Flowers are white, 3 -4 mm long with 2 sepals and 5 petals. Flowers grow in a loose cluster in groups of 5 -12. M. linearis has three segmented capsules that contain shiny, black, disk shapped seeds.

Seed
Montia linearis: MOLI
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
Features
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
Latitudinal Cross Section: : rhombic 
Longitudinal Cross Section: elliptical 
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.
