Indigenous Borneans knew a tree was two distinct species— genetic analysis confirms they were right

By | Botany, News, Plant Science

Over 200 years ago, a Spanish botanist described Artocarpus odoratissimus, a species of fruit-bearing tree found in Borneo and the Philippines. The Iban people, who are indigenous to Borneo, know the tree to have two different varieties, which they call lumok and pingan, distinguished by their fruit size and shape. Despite this knowledge, Western botanists have long considered the tree as a single species, but a genetic analysis confirms the Iban people were right all along.

Researchers Reveal Global Biogeographical Patterns and Correlates of Floral Longevity

By | News, Plant Science

The length of time a flower remained open (i.e., from anthesis to flower senescence) is called floral longevity. Floral longevity has been considered as one of the most important reproductive traits as it determines opportunities for pollen dispersal and capture of pollen by stigmas as well as has the potential to influence intra pollinator foraging and opportunities for geitonogamous self-pollination.
