Clypeoceras indicansCompass Staghorn Fern

On the morning after the first hard rain at the end of the dry season, only a few plants had opened their pale flowers. By noon the corolla had collapsed, and the anthers were already touching the stigma. The flower is built mainly for self-pollination, yet I saw small flies moving over the wet sand and licking at the mouth of the flower before passing to a neighboring stem. Pollination here is not a spectacle, but a brief insurance policy enacted in the hours after rain.

Lean Sand-fast does not appear evenly across the forest floor. Sparse groups of a dozen or so stems follow shallow depressions, the shade of fallen trunks, and narrow lines where rainwater sheets over the white sand. Its fine seeds, released after fruiting, seem not light enough for long wind dispersal, but are pushed a few meters across the wetted surface by a thin film of water. The patches are not evidence of vigor; they are the trace of seeds caught by the microtopography of the sand.

Outside its flowering period, Lean Sand-fast is little more than a grey-green needle dusted with white sand, and a collector would easily have taken it for a young sedge or the broken stem of a seedling. The flowers appear only for a few weeks at the end of the dry season, and then chiefly on mornings after rain. To those walking the white-sand forest from the Essequibo river routes, it served as a marker along narrow paths; in a herbarium, it would have remained an unnamed fragment, long placed among misidentified material.
