It includes novel data about plant phenology, flowering, insect visitors, seed germination, fruit morphology, and allometric relationships. This work includes an in-depth review of the most recently published information on the topic. Mora de Castilla is an economically important fruit crop from the Andes. It has been crossed with other Rubus species due to its high yield and everbearing habit. Currently, it is an economically important plant.
