FAGACEAE

anthers. The stigma protrudes beyond the sta. in most firs, so as to 
be touched first, but every stage can be found from highly protogy- 
nous firs, with very protruding stigmas to almost homogamous firs, 
whose stigma does not protrude and where self-fertilisation is the rule. 
Eurya Thunb. Theaceae. 36 sp. Mexico, S. Am., W. and E. Ind. 
Euryale Salisb. Nymphaeaceae (in). 1 sp. S. E. As. Fir. epigy-
