Bloom Period






Abbreviation: GICA

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.
