More Old Castle Down limestone

I was back working on Old Castle Down today and took some time out to investigate another exposed limestone outcrop, this time on the north-facing side of the hill (SS899758).

The flora was broadly similar to that on a nearby west-facing outcrop I investigated a couple of weeks ago (see here), with the notable absence of Entosthodon pulchellus. A few additional species were noted, however, including Scapania aspera, Dicranum bonjeanii and Tortula subulata (photos of these three species below). A small patch of the latter was growing in a rock crevice, the elongated capsules betraying its presence - a new species for me.
