Star Cloak Fern
notholaena standleyi
The Star Cloak Fern (Notholaena standleyi) is a highly resilient, xerophytic fern native to the arid desert regions of the southwestern United States and northern Mexico. Perfectly adapted to extreme environments, this remarkable plant typically grows in dry, rocky crevices and canyon walls where soil is minimal and water is highly scarce. Its most outstanding feature is its poikilohydric nature, commonly known as a resurrection capability. During intense dry spells, the fern can lose almost all its water content and curl into a tight, dormant brown ball, only to rapidly unfurl and restore its rich green color within hours of receiving rainfall. This survival strategy allows it to thrive in desert landscapes where other fern species cannot survive, anchoring rocky substrates and providing sheltered microclimates for tiny desert organisms.
生息地: Found in dry, rocky crevices, canyon cliffs, and boulder fields, particularly on granitic, volcanic, or limestone substrates in desert zones.
外見
This small perennial fern reaches heights of 5 to 25 cm, featuring distinctive pentagonal or star-shaped fronds that are deeply divided into lobed segments. The upper surface of the leaves has a dusty, grayish-green coloration when hydrated, whereas the underside is covered in a brilliant, powdery yellow or pale orange waxy coating known as farina. During periods of drought, the fronds curl tightly inward, exposing the pale, farina-coated undersides which reflect harsh desert sunlight and resemble small, compact, yellow-brown knobs tucked into rock fissures.

おもしろい事実
Despite appearing completely dead and brittle during dry months, the plant can fully rehydrate and photosynthesize within 24 to 48 hours of rain.
Its scientific name 'Notholaena' comes from Greek words meaning 'spurious cloak', referring to the hairy or powdery margins that cover the spore cases.
The bright yellow powder (farina) on the leaves can rub off on fingers, leaving a glowing waxy outline like a stamp.
特殊能力
能力
Resurrection Capability
It is poikilohydric, meaning it can survive near-total dehydration by curling into a dormant ball and rapidly reviving upon contact with water.
能力
Farinose Defense
The underside of its leaves features a waxy, yellow powdery coating that reflects intense solar radiation and minimizes water loss through transpiration.
能力
Lithophytic Anchoring
Its fibrous, tough root system penetrates tiny rock fissures to secure the plant and extract trace moisture and minerals.
