Morphology

The linear leaves present a helical arrangement on the secondary branches, showing a thickness notably inferior to that of other related species. The specific epithet refers to the thin and flexible appearance of its young branchlets.

The male and female reproductive structures develop separately, although specific details regarding the maturation of their fleshy seeds lack detailed descriptions in recent scientific literature.

Interesting facts

The first specimens were described by European researchers in the second half of the nineteenth century. The name highlights the unique shape of the plant's vegetative organs.

  • The thread-like shape of the crown helps the plant to efficiently capture diffused light.
  • All parts of the shoots secrete essential oils with a characteristic coniferous aroma.
