Agave muxii to ładny ciekawy gatunek, co widać na zdjęciach w linku niżej.
Abstract
Two new species of Asparagaceae from the southern portion of the Sierra Madre Oriental, in Guanajuato and Querétaro states, Mexico, are described and illustrated. Agave muxii from Querétaro is included in Agave, subgenus Littaea, section Choritepalae. It is ditinguished from the other species of the group by its robust inflorescence, which is densely covered from base to apex by purple bracts, and by its purple flowers, stamens and anthers. Agave muxii represents a noteworthy discovery for the Mexican flora, not only for its beauty, but also for its restricted distribution and rarity. Yucca pinicola is known from Guanajuato and Querétaro states, where it grows in the pinyon forest. It is included in Yucca section Sarcocarpa and is related to Y. filifera, Y. schidigera, Y. schottii and Y. treculeana.
