'Lavatera sylvestris' - Lavatera cretica or possibly Malva sylvestris?

[David Price]

It's a pity the collector did not quote the author.

If he meant Lavatera silvestris Brot., this is synonymous with Lavatera cretica L. which is now called Malva pseudolavatera Webb & Berthel. in Stace 3 ed where it is pointedly distinguished from Malva sylvestris L. by its greyish hairiness, dull lilac flowers (not bright pinkish-purple with dark stripes) and epicalyx segments fused proximally (not free to base).

I see a difference between this and Curnow's 1878 specimen http://herbariaunited.org/specimen/309007/ which is clearly Malva pseudolavatera Webb & Berthel. and would hazard that this (Smith's) plant is Malva sylvestris L.
