Summary of the best-fit photosynthesis model, which included: treatment, selfing, and species but no interactions between them.

Variable	Parameter estimated	t value	P
Intercept	9.86	7.38	7.26e‑08***
Wet treatment	2.96	6.14	6.37e‑09***
Selfing	–4.64	–2.23	0.035*
S.H.	–2.85	–3.37	0.003**

S.H., S. hookeri. Estimated parameters with their associated P values are shown for all variables in the model (selfing, treatment and species, no interaction was included). A mixed model with a nested random intercept for each mother was generated (see in Statistical Analysis section). Significance levels: P > 0.05 (ns, not significant); P < 0.05 = *; P< 0.01 = **; P < 0.001 = ***.
