Discovered in 3097 by the Ice adapted Genen clade House Briggs in Vulpecula, the sub-sophont alien xenophylum Lignosagittiae is found in the ice ocean of Fuego 485 ly from Earth, now an alien reserve.
Most members resemble free swimming arrowheads or upside down boats, propelled by several pairs of paddles. The various species of lignosagittae, known as gnosags, feed on microbacterial mats and other chemotrophic life around black smokers at the dark bottom of the ocean. Some mats attain a colonial organisation , including sexual dimorphism and use of the gnosags for genetic transfer analogous to pollination. The illuminated bullseye flowers attract the keensighted gnosags and paint them with gamete gel which is carried to the mat of the opposite sex for cross-fertilization.
In 4670 a particularly promising species of gnosag had been uplifted to sentience by the Genen in the nearby europaformed ice world of New Charon, and invited to join the Zoeific Biopolity as a member clade. However when the Gnosags travelled into space in their simple self made wooden craft to meet the Genen and Biopolity representatives, their keen dark adapted eyes saw the distant Ring Nebula in Lyra. The greater part of the Gnosag race decided to set off in relativistic ships to seek the giant bullseye flower of their subconscious longings.
The quest of the Gnosag dreamflower is held as an example of morphological resonance by neojungian philosophers.
