Jardin botanica -University of Lisbon

These are flowering spikes of agave. the first one I don't know the species. no label and I wasn't about to crawl in with all those spiky things.

the 2nd one is agave chiapensis native to mexico and guatamala

the next pic is just a neat tropical effect in the monocot garden

the variegated yellow plant, i can't remember if that was a yucca or a dracaena. I think it was a dracaena and it had a very very spiky foliage.

I think that is one of the auracarias. not the one we grow in vancouver, monkey puzzle, auracaria auracana, but it may be A. bidwelii - the one we grow at bloedel under the dome. huge pine cone and they had one attached to the tree for all to see. they are the size of bowling balls and weigh a few kg, so you have to be wary when they are coning and dropping their cones. they can knock you out.

the last pic is a blooming opuntia, again not sure which species.

they had lots of different cycads and good information panels in both portuguese and english.もっと詳しく
