|Cliffs at Penmaen overlooking Threecliffs Bay|
where all of Glamorgan's four Tortella species grow
Below left: Tortella sp. growing with Pleurochaete squarrosa (in centre of the image) becoming crisped. Below right: T. flavovirens sample collection point.[At least that's what I thought! After making this post I found a second sample I'd left in my coat pocket, which I was convinced at the time was probably inclinata; to my relief this turned out to be the case. Which species is represented in the general shot above alongside the Pleurochaete I'm now not sure as there's not really enough detail in the image. The difference between the two species using a lens is in fact rather striking when they are side-by-side, the shoots of inclinata being larger and more erect, with a stronger nerve appearing more prominent in a more boat-shaped leaf apex, reminiscent of Trichostomum crispulum]. Plants showing these characters were widespread on the cliff I looked at, but it's interesting that both species grow mixed in together.
