Summary
[edit]DescriptionOnionweed seed and flower heads top view.jpg |
English: Side view of onion weed (Nothoscordum × borbonicum) inflorescense and seed head with open capsules. Photographed on a black background with ruler for scale. Separate seeds are located on the ruler around the 9 cm mark. Leaves, bulbs and peduncle not shown. Four specimens at different stages of maturity, collected at western Sydney, Australia.
Flowers are white, six-petaled, with green bases and prominent yellow anthers. Dry seed capsules are light brown, three-lobed, with black seeds. (A small quantity of blue putty can be seen at the base of the seed head, used to hold it upright.) |

Note: Nothoscordum × borbonicum is often misnamed as Nothoscordum gracile or Nothoscordum indorum [1]
[Post-processing: file adjusted off-camera for rotation and tone curve (L* channel). "White" paper backing behind ruler likely has fluorescent brighteners, is slightly bluer in tone than the white flowers, and should not be used as a white-balance reference.]
