In spite of the prevalence of spiny plants in many plant communities, little is known about how Subject Editor: Lonnie Aarssen the LES relates to defence and growth rate across these species. We grew 42 spiny Editor-in-Chief: Dries Bonte species, from diverse environments, under common garden conditions for 15 weeks Accepted 13 January 2020 and measured LES (leaf N, SLA and assimilation rate), defence and growth traits.
