One of the biggest areas of occurrence of succulent plant family Crassulaceae is undoubtedly Mexico. Among other species, there is an area of ​​occurrence oaxacaum Sedum, a low species with succulent stems poléhavými. Extent of occurrence is the state Oaxaca.Ve Guatemala Central American country is growing species, which is from P. oaxacanum almost indistinguishable, Sedum australe. It is endemic Guatemlský and its occurrence is widespread in the volcanic mountains Tacana, Santa Maria, Sierra de los Cuchumatanes and Tajamulco, who is also the highest mountain in Central Kordilier that prochází.Gautemala Guatemala is an area of ​​tropical climate in which the temperature varies at 600 m above sea výšce.Do the average annual temperature of 25 ° C, from 600 to 1800 m it is 20 ° C to 3200 C and 14 ° above 3200 temperatures drop from 10 ° C stouopající altitude to zero, the highest peaks permanent snow cover.

Sedum australe grows in scattered mountain meadows, veskalách, the rough cliffs overgrown with moss and crevices, at altitudes of 1200 to nearly 4000 meters. Sedum australe highest award was made in 3707 at the height of Volcan de Santa Maria. Nature produces large colonies and impenetrable forests, or dangling bunches, long succulent stalks whose top is a cluster of densely crowded porosten, flattened leaves. The stems are succulent, towards the base and dřevnatějící kolínkách zakořeňující very well. Stem is also on view only distinguishing feature between Sedum and Sedum oaxacanum australe. Nature is not very decorative, but sometimes appears as půdokrvvná plant in the gardens of local residents.

Because Sedum australe is not common in cultivation, I asked Ray Stephenson, whether mentioned in my collection of species and may provide for this article's photo. Very willing to plant and photographed images sent me this comment: "australe Sedum Sedum is greater than oaxacanum, but only slightly. The stems are rough, otherwise the two species are indistinguishable from each other. "
Because I Sedum oaxacanum in cultivation, I could at least compare the two plants from photographs.

Thank you Ray for his willingness and cooperation, through which I could shed light on the latter, which in literature is not too many references.
