later field notes
2026-06-24 · A Few Nights in the Rains

After roughly three days of rain in the valley bottom, Umbraflora pallida loosens its corolla only before the wet leaf litter dries. The urn holds little nectar, but gives off a faint fermenting odor like humus. Fine pollen smears on the rim suggest that small flies moving through the dark understory enter by chance and touch the stigma as they leave.

2026-06-24 · Limestone Fissures

Around fruiting plants, powder-like seeds lie thinly over the moss after the capsule splits. They are light enough to be carried by water dripping from the valley wall and drawn into limestone fissures. Only those reaching the right fungal layer appear to germinate, so colonies do not spread broadly; a few dozen pale stems line a single hidden flow of water.

2026-06-24 · A Flower That Leaves Poor Specimens

Collected stems darken within half a day, and the urn-shaped flower collapses until it is hard to distinguish from leaf debris. It was likely dismissed in older notes as a fungus or an immature orchid. Hunters and resin gatherers may have remembered the “shadow flower” because, on wet animal tracks leading from limestone gullies back to the main river, its white points marked the direction underfoot.
