Synonym: None.
Special status: None.
Recognition: Small (<1 mm dia.) julaceous plants with three rows of tightly appressed, deeply bilobed leaves. Lobe tips sharp. The deeply divided leaves in three rows overlap so closely they look like six rows of simple leaves. Very soft and fragile under the forceps (leaves are hard to detach intact). No oil bodies. Covered with a white, filamentous coating giving silvery appearance in the field. Very similar to A. julacea, from which it is distinguished by being paroecious (but note male bracts are not ventricose) and the elaters having three, or rarely two, slender spirals (vs. 2 strap-like spirals).
Distribution: Terrestrial. Subalpine zone in high mountains, typically over 5000'/1500m, fairly abundant.
Comments: More common than A. julacea. This species has also been reported from California, based on a Bolander collection believed to have been collected on Mt. Dana (Howe 1899).
