ST27D, locate to the north of Cardiff docks, has been particularly tough. There is lots of wasteground vegetation in this tetrad and it has proved interesting for dockland aliens (including Senecio inaequidens and Lepidium graminifolium) and micro-moths, but not so for bryophytes. It is a dry area and almost lacking in woodland, so many common species are missing (or just missed by me). I've only recorded 35 taxa here...I'm sure there will be others, but it is probably not the best use of my time scratching around trying to find them. The only records just about worth mentioning are Brachythecium mildeanum and Dicranella schreberiana.
ST27E was better largely thanks to the Howardian Local Nature Reserve, which has some wetland areas as well as pockets of boradleaved woodland. Around 55 taxa were recorded last Sunday morning, the highlights being Marchantia polymorpha ssp. polymorpha and Oxyrrhynchium speciosum growing together beneath Phragmites.

Elsewhere on the site was this patch of Leskea polycarpa on an ash bough away from water, though the surrounding tall herb vegetation might hold standing water in the winter.
