Frailea phaeodisca

lb rb    







This Site is a resource for those interested in the genus Frailea: Gorgeous Flowers, Unusual Shapes & Colors, Exotic Locations and many other features make these cacti a cheerful study for all who love and enjoy plants! These small globular to short cylindrical plants are found in Argentina, Bolivia, Brazil, Paraguay and Uruguay. They were initially classified as Echinocactus; beginning with Echinocactus pumila in 1838. The genus Frailea was created by Britton and Rose, in their monumental work, ‘The Cactaceae’, first published in 1922. The genus was named for the Spaniard, Manuel Fraile, who dedicated many years in caring for the U.S, Department of Agriculture cactus collection about the time that Messrs Britton and Rose were preparing their book.

How was this site born? It coalesced from the desire of individuals who dearly adore this genus of cacti! We wanted to create a hub of information that might assist in familiarizing you with these terrific, but widely unrecognized little plants. Over time, we hope to see this
site grow into a useable and reliable web resource. Whether you are new to these fabulous plants or an old hand, there is much to learn and much to gain in appreciating these little gems! Join in!

Why re-invent the wheel? The concept of this website has been unashamedly copied from the Ariocarpus Living Rocks from Mexico website with kind permission from its webmaster and site editors.  We salute their excellent website and hope that other genera will be covered similarly, ultimately resulting in a  comprehensive on-line Cactus Lexicon.
