Ursínia nana. Ursinia nana subsp. nana

Authors: Molero i Briones, Julià;

Ursínia nana. Ursinia nana subsp. nana

Abstract

Ursinia nana DC., Prodr. 5: 690 (1836) subsp. nana Ursinia nana (Anthemideae, Asteraceae), és una espècie adventícia d’origen sud-africà en procés de naturalització a Europa, d’on fou descoberta per primera vegada per J. Molero l’any 2006 a la comarca del Priorat (Falset, Catalunya). Alguns detalls de l’arquitectura floral i de la dispersió de fruits ens revelen fascinants, sofisticats i eficients mecanismes reproductius no presents en altres Anthemideae mediterrànies. Abans d’entrar en els aspectes demogràfics i de respondre a la qüestió primera i definitiva del futur esperable a Ursinia nana en aquest nou enclavament colonitzat, es sintetitzen les dades relacionades amb la morfologia, taxonomia, habitat, cicle vital, biologia reproductiva i citogenètica de l'espècie. Finalment, s’analitza el procés d’expansió i s’il·lustra com es produeix l’entrada i establiment d’una nova espècie exòtica a la flora catalana
