Looks like one of the Cruciferae (nom. alt Brassicaceae), which makes your
'seeds' fruits. Picture does not really give much detail.

Can't find this flower in my books...

Height about 40" (100 cm). First 20" (50 cm) have leaves alternate. Then
there is a distinct bend in the stem. The top 20" (50 cm) have what appear
to be many seeds (?) arranged in a horse's tail appearance. Each seed is
about 2" (5 cm) long, very thin, slightly ribbed along the length, and
straight to slightly curved. Color green throughout.

A second specimen had a strange series of twists and turns instead of a
simple bend in the middle, as if it was trying to be a climber. Not
surprising, since both specimens had toppled under their own weight. This
second specimen also looks like it tried to develop 2 additional
"horsetail" branches, but they weren't anywhere near as vigorous as the
main one.

Date: June 10.
Location: San Juan Islands, Washington State, USA. (On an undeveloped
island, so probably native to the area.)

Please excuse my poor knowledge of botanical terms!

Your help greatly appreciated.
