Parajubaea torallyi

Parajubaea torallyi, commonly known as the palma de Pasobaya or Bolivian mountain coconut, is a species of evergreen flowering plant of genus Parajubaea, in the family Arecaceae, closely related to the coconut palm in the tribe Cocoseae. It is endemic to Bolivia, where it grows in dry forests on steep rocky slopes at 2,400–3,400 metres (7,900–11,200 ft) in altitude. In its native habitat, due to high altitude, low night temperatures often drop to a range of -3C to -9C during local winter time (July, August), with considerable temperature spans between day and night and practically no precipitation during that time. Annual rainfall is around 500-600mm only, with majority during 2-3 months of the year. The palm therefore naturally occurs only in some valleys that have waterlines available within stony and sandy mountain ground for deep root access. Humidity in these micro climate valleys is quite high despite low precipitation, which might contribute to relief from heat stress by acquiri......read more on Wikipedia.
