Hi

I´m currently living in Azores, in a recent trekking I have found two (or one dimorphic) species of Drosera,

can you help me identify then and/or suggest I recent dichotomic key to the genus?

Thanks for your time

Species "A" looks like Drosera capensis.
Species "B" looks like Drosera aliciae.

That is a guess, many rosetted Sundews look similar.

These are not Arizona natives. Both come from South Africa. Possibly somebody planted them in the wild as an experiment.

Good growing,
Mike

I will agree those plants look like D. capensis and D. aliciae. Looking at some climate data, it seems the conditions there are pretty similar to South Africa where these plants are native to.

According to Google, Azores, which is near Portugal, tends to be warm
and wet. Sounds perfect for sundews.

They definitely aren't native, though. I agree that someone must have introduced them, though, given how easily those species grow, it could have been accidental.

You may want to check the local laws, just in case, but they should be legal to collect if you want a few. They're certainly very pretty.

hi

thanks for your help :)

I agree with your assessment but still, and to confirm :)

can´t it be Drosera alba or a hybrid between D. aliciae and D. capensis?

again thanks for your time

Hybrids are possible, but none of these plants look like such. I'm assuming you mean Drosera capensis 'albino'? It's certainly possible you could find some of those growing if you search around more. Drosera alba is a completely different South African species that's actually fairly rare.

I would recommend removing them all, or as much as you can, unless there is some law that would prevent you from removing non-native species.
