- Scientific Name: Gilia capitata
- Family: Polemoniaceae
- Common Names: bluehead gilia, globe gilia
- Codon: GILCAP
|Genus:|| Gilia Ruiz & Pav.|
|Species:|| Gilia capitata Sims|
Annual herb from a taproot.
Leaves pinnately lobed, segments and rachis slender, reduced upwards on stem. Leaf axils and midribs generally hairy.
Inflorescence terminal, spheric, consisting of many unstalked flowers, generally more than 8 per head, corolla bluish. Corolla lobes 5, generally about as long as the corolla tube. 5 sepals, membranes white, expanded during fruiting. Stamens equal as long as or slightly exserted from corolla lobes.
Fruits are 3-chambered capsules, each bearing 1-3 seeds.
May, June, July
Mostly west Cascades, southern BC to California occasionally east to western Idaho.
Found in open places below 7,000 ft. elevation. West-side forest, meadow, and east-side forest. Grows in open, sandy, or rocky soils, and grassy hillsides.
Payómkawichum use of seeds as food.
Rich nectar source.
Seeds do not require pre-treatment but germination improved by the presence of charred wood or aqueous extracts of it.
Seed sample from: 2011
Average Measurement: 1.7 x 1.1 x 0.7
Measurement Range: L: 1.2 – 2, W: 0.75 – 1.4, D: 0.5 – 1.1
Shape: Seed narrow at hilium end, broadening at opposite apex. Hilium inconspicuous. Uniformity in shape is not that common, but most seeds take a relatively teardrop shaped.
Color: Seed is brown, very bumpy, and slightly lustrous.
Surface: Seed coat becomes very mucilaginous and stringy when wet.
Could be confused with COGRX, but GICA is about ½ the size and does not have sulcus.
Latitudinal Cross Section: elliptical
Longitudinal Cross Section: obovate
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.
