Euphorbia species of the garigue

Post by John Holst » Mon Apr 13, 2009 8:56 pm

Hi

This is the first of many posts with pics of plants, - especially from the garigue area surrounding the Danish holiday centre at Bisqra just north of Mellieha.

I stayed at Malta last week, and in 2008 I stayed there for a week in March.

He are some Euphorbia species that have given me some trouble. Flora Europaea says that E. melitensis is another name for E. spinosa, and I think my pics show what looks like E. melitensis.

Euphorbia A and B give me trouble because I am not sure which species can be found in the garigue.

Euphorbia heliscopia, it would be if found i my home country (Denmark), but are there alternatives in Malta?

I can see that I have to resize my jpg-pics, so they will be attached to next posts.

When I chose a Filename and press 'Submit' or 'Add Attachment', I just get the message:

'No post mode specified'


So I'll have to fight a bit with the issue of how to attach a pic-file.

The first one is E. melitensis
The second one (A) should be E. pinea
B should be E. exigua
The last one is E. helioscopa

agree with robcar.

yes there is some issue about Euphorbia melitensis and Euphorbia spinosa. Maltese people say its endemic, other botanists say it is just a form of E. spinosa.

Thanx for helping me out. I think I will stick to the melitesis name and skip spinosa.

E. exigua I know very well from Denmark, where it is a small plante never getting higher than 30 cm. Flora Europaea says that E. exigua is up to 35 cm.

But species B plants were all between 50 and 70 cm high, so it has to be another species than E. exigua.

Im still sorting out all my pics from 2009. Today I found this one, which I would say shows a typical very small specimen of Euphorbia exigua.

But since this is not Denmark, you may have a more correct name for this Euphorbia.

I've done a bit of botanical detective work on species B without coming to any definitve conclusion. As it is right now my best guess is Euphorbia terracina.

I have always seen E. terracina being multibranched at the base with reddish stems growing in sub-sandy places. On the other hand, I assume that if seeds are carred in ruderal/soily areas, it will also grow fine (perhaps a bit atypically) despite not its preferred habitat.

The photo is not really good for conclusions, though I might also put in the bowl of ideas a distorted E. pinnea.
