An in situ inventory is made of the native and introduced plant species that are cultivated and marketed in the four Pelileo plant nurseries, and all of their owners are interviewed. The dual hypothesis that the nurseries represent an economic and bu

The hypothesis that the traditional use of both introduced and native plants in Ecuador is analogous is validated in this research. One hundred and twenty-four interviews were gathered from 13 Ecuadorian provinces, 99 females and 25 males, 107 of whi

Patterns of speciation in the angiosperm genus Santolina (Asteraceae, Anthemideae) have recently been intensively studied, but progress is hampered by nomenclatural confusion. In this paper, the species S. ageratifolia Barnades ex Asso, S. pectinata

Morphological variation within and between taxa of the Santolina rosmarinifolia L. aggregate were studied. This work demonstrates that polyploidy and hybridization may be effective evolutionary mechanisms of speciation, promoting the persistence and
