Saunders DURING recent years there has been a renewal of interest in Essex bryophytes. Many of our records date from the end of the last century, and there is no doubt that conditions have changed and are still changing. It would be extremely difficult to rediscover some of these plants and it is quite possible that a few may now be absent from the County; luckily, however, we have several newcomers to the list which well redress the balance. In particular, there is a notable absence of the Orthotrichums and Ulotas, an absence that has also been commented on in the neighbouring county of Hertfordshire, most of these species grow as epiphytes on trees. Some of the more interesting observations are detailed below. The names used follow those of An Annotated List of British Mosses, by P. W. Richards and E. C. Wallace, Trans. Brit. Bry. Soc, 1950, and An Annotated List of British Hepatics, by E. W. Jones, Trans. Brit. Bry. Soc, 1958. Dicranum scoparium Hedw. A well-marked variety of this moss was found on Lingwood Common during a Field Club outing. It was the var. paludosum Schp., a tall growing plant (3 inches) with undulate leaves and stems covered with white tomentum. Campylopus piriformis (Schultz) Brid. On the Fungus Foray in Epping Forest this year, this moss was found, by the Cuckoo Pits, in fruit with aggregate capsules. In barren plants the tufts are covered with broken off leaves and the moss reproduces vege- tatively. Capsules are uncommon in Essex.
