length. Narrowly triangular blades, produced in upright tufts, are bipinnate to tripinnate with dark-stalked, cone-shaped pinnules. The free veins fan from a dark basal spot on the pinnule and terminate in the tips of the minute marginal teeth. Fertile pinnule tips are deeply indented with a lone medial cleft that bears a species-specific (for temperate maidenhairs), single (mono) indusial flap that encloses and protects the sori.
range and habitat: Of rocky slopes and dryish woodlands, this lovely species is found in China, Taiwan, Korea, and Japan.
culture and comments: It is quite reasonable to confuse this species with Adiantum venustum when fertile material is not present. The latter has a similar silhouette but creeps about and carries dual sori rather than a single sorus on the fertile pinnules. It is also easier to cultivate. Both are enhanced by salmon-tinged fresh spring foliage. Once established Adiantum mono-chlamys is a unique and rare addition to the collector's garden, so give it a prime location. Pot or foreground culture with attentive vigilance, gritty soil, and medium shade is appropriate.
