3 plants from our National Botanic Garden in Chile.

Hello to all.
Please can you identify this these 3 plants. In Chile we are in Fall time and I love to collect some seeds,... I am trying to identify several plants I found along out National Botanic Garden here, in Viña del Mar, Chile. (jbn.cl). Pics "bark, seed 1 and seed 2" are from de same tree.

Thanks and regards from Chile,
Gabriel.

 

Seed 3 is Ostrya, maybe O. virginiana, which grows at least as far south as Central America, but in a botanical garden, it could be from anywhere, so could be another species.

 

Thanks Wendy for your comments!!!

Gab.

 

The first one is a Celtis sp. and the last one looks like a Malus baccata.

 

Thanks for the information!
