Appendix C. Crosspollination rate for n pollinators.
By analogy with Eq. 12, in the general case of i = 1…N pollinators, all of which contribute to crosspollination, the crosspollination rate due to the pollinators is
(C.1) 
where the variables have the same meaning as before, but for pollinator i. Again considering two cases;
(a) if not all ovules are fertilized by autonomous selfpollination, by the wind or by mechanical contact, i.e., if _{fert} > T, then by analogy with Eq 8a;

(C.2) 
and p_{i} is given as in Eq. 8b, but replacing _{b} with _{i} and _{h} with .
(b) if _{fert} < T, then by analogy,p_{i} is given as in Eq. 9, but again replacing_{b} with _{i} and _{h}with .
The crosspollination rate due to the wind is given by Eq. 17 in the main text.
(a) if _{fert} > T, then by analogy with Eqs. 14 and 15 in the main text;

(C.3) 
(b) if _{fert}< T, then by analogy with Eq. 16
