The latest issue opens with a paper by Rosalyn Marshall, Hugh McAllister and James Armitage describing three new infrageneric hybrids in the genus Hedera (Ivy).
The authors consider material from the UK, Spain and the USA; the distinguishing features of the three newly named hybrids are discussed and there is a key allowing identification of the two hybrids known to have arisen in the UK.
This paper comes hot on the heels of a new monograph by Rosalyn and Hugh, published by the Royal Horticultural Society, which covers the surprisingly colourful diversity of ivy, from the 12 species to around 200 of the most widely grown cultivars, which are illustrated and fully described in the monograph. It also covers the benefits of ivy for wildlife, uses in folklore and the decorative arts as well as the botany, ecology and evolutionary history of the genus. There is a checklist of 2000+ ivy cultivars and scientific names, alongside advice on cultivation and propagation. You can order the monograph here.

Paul Ashton et al. looks at regional stability versus fine scale changes in community composition of mesotrophic grasslands over a 25 year period, while Clive Stace offers us new combinations in six genera of the British flora and Pete Stroh, BSBI Scientific Officer, describes a putative new native taxon for Britain. And no, I'm not going to spoil the surprise by telling you what it is!
But New Journal of Botany has always looked beyond British and Irish shores, and in this issue we are also delighted to publish a paper by Sanna Olander and Torbjorn Tyler on Erigeron acris in Fennoscandia, while Declan Quigley et al. document first records of Prickly Palm Acrocomia spp. from Irish and northwest European waters.
