photograph of this, the most widespread species from Rio
Negro in the south to Salta in the north, Patagonia. Many
different forms exist. Most
of the slender stems become detached during winter. If grown
in full sun, the new growth will flower profusely in spring
and summer. Flowers
are a pale to deep yellow and the stigma can be from almost
white, pink to deep red.
Certainly the most well known species in cultivation. (P.
