Desert flower of Chile: Doquilla, Pata de guanaco (Cistanthe grandiflora) in southern Atacama Desert. Used to be in the family of Portulacaceae, now in Montiaceae.
Fog oasis. Rare desert plants. “Riparian consciousness.” Caretaking of dry forests. Specialized fog-capturing tree roots in sand dunes, where up to 40% of local plants are endemic. Ancient forest of Usaca. Earth’s driest (non-polar) desert. “The south coast of Peru is a hyperarid environment in which both people and plants are dependent on sporadic and unpredictable sources of water, but also,crucially where both depend intimately on each other. [...] Nazca is now famous for the giant geoglyphs [...]. Yet, Nazca’s fame by virtue of this [...] ritual [desert] space is somewhat ironic, since the people who made the Lines actually lived, farmed and foraged within the riparian dry forests, of which there are few remaining traces on the south coast today [...].
Examples of endemic plants on south coast Peru. A Ambrosia dentata ; B Cleistocactus acanthurus ; C Krameria lappacea *; D Haageocereus pseudomelanostele ; E Tecoma fulva subsp guarume ; F Alstroemeria aff. violacea ; G Evolvulus lanatus ; H Cistanthe paniculata . *also known from arid N. Argentina, Bolivia and Chile.

[Tree roots which capture moisture from fog, many litres collected each night.]
The dry forest of the Peruvian south coast has undergone an almost total process of deforestation. [...] Indigenous communities still hold [...] traditional knowledge. Relicts of natural vegetation, traditional agriculture and agrobiodiversity continue to sustain [the] ecosystem [...]. These problems are particularly acute in the dry forests of arid areas [...]. The south coast of Peru is part of the Pacific coastal belt, which is one of the world’s oldest and driest areas known as the Peru Chile Desert. Its climate is hyper-arid, with an average annual precipitation of only 0.3 mm per year [driest non-polar desert on the planet]. [...] Equally important, as a source of moisture for plants,is coastal fog (‘garua’) occurring from June to December. These water sources support a surprisingly rich, highly adapted flora and fauna, including habitats with high endemism in quebradas (inter-Andean valleys) and lomas (fog meadow) [...]. In individual lomas communities, plant endemism at species level often exceeds 40% [...].
The project studies we present here increased the total Ica coastal flora (below 1500 m) from around 180 [...] to over 480 species [...]. We expect that total to rise to over 530 species because of the highly ephemeral nature of isolated and disparate plant communities [...]. Of this total number, around 29% appear to be endemic to Peru and Southern coastal Ecuador, and about 10%endemic to Ica and Southern Peru [...].
The riparian oases and associated lomas, quebradas and marine habitats of the south coast have supported a trajectory of human settlement and adaptation which spans the Holocene. Thus, the ancient human interaction with the environment is universally evident in the historical ecology of the region [...].
Huarangos of Ica can reach huge sizes — this tree is unique but today nearly dead due to insect plagues, many veteran specimens have now been converted to charcoal (2001).
We measured the quantity of atmospheric moisture captured by a small tree (three metres in height with a crown width of four metres) at up to nine litres per night. Through excavation under huarango canopies in sand dunes in fog areas, we found that the buried branches develop a fine matrix of superficial adventitious roots, presumably to capture this surface moisture. Areas of heavy nightly fog are indicated by the presence of epiphytic Tillandsia species (including T. purpurea Ruiz. & Pav.) growing in huarango, and at higher elevation in Cacti.
Vegetation types in Ica. A Prosopis dry forest (2001); B Riparian oasis dry forest (2005); C Prosopis dune forest (windy zone) (2002); D Cactus scrub forest (2008); E Acequia and huerta vegetation (2002); F Lomas (2001); G Tamarix aphylla invasion (2009); H Marshy spring or ‘ Puquio ’ (2005).

~ CISTANTHE GRANDIFLORA ~ la famosa "pata de guanaco" Ahora la pillé tal vez no tan verde, pero de increíble color igual, resaltando sus violetas, resistiendo. Cada plantita con su servicio ecosistémico y de tremendo valor paisajistico. A pleno sol y sin protección. Una belleza (en El Yeco, Algarrobo, Valparaiso) https://www.instagram.com/p/CZj_cKHOyBf/?utm_medium=tumblr
The Calandrinia aka Cistanthe Grandiflora (Rock Purslane) is in bloom! It’s so easy to grow and propagate - if you want to propagate some, check out my video on propagating Calandrinia💚 Have a beautiful and health-filled day!
