Description

O. uniflora is a short, annual, parasitic herb that is glandular hairy. It is somewhat fleshy. The stems of this plant are short (1 - 5 cm) compared to the pedicles, which are 3 - 10 cm long. The herb has no leaves or bracts. Flowers 1 - 3, on long pedicles. Calyx 5 -12 mm, with brown to purple corolla that measures 15 - 35 mm. Flower two lipped, with five finely fringed lobes.

Orobanche uniflora

Seed sample from 2011

Features

Average Measurement: 0.2 x 0.1 x 0.1

Measurement Range: L: 0.1 – 0.3, W: 0.1 – 0.2, D: 0.1 – 0.2

Latitudinal Cross Section: elliptical Lat cs.png

Longitudinal Cross Section: elliptical Long cs.png

Shape: Seed very small, slightly narrower at hilum and opposite apex. Seed generally egg shaped, some specimens more slender than others.

Color: Most seeds brown, some tan.

Surface: Seed coat deeply honeycombed, and somewhat iridescent.


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.
