On the cliffs, east of Brighton, are found _Acaulon triquetrum_, the only British locality for this; also, _Gymnostomum tortile_, the _var ß subcylindricum_ of which occurs on a hill near Greenway Station, _Phascum curvicollum_, _Pottia cavifolia_, _Trichostomum mutabile_, and _Trichostomum crispulum_. _Anacalypta Starkeana_, _ß brachyodus_, are all frequent, and _Webera carnea_, at Black Rock. The sides of Woolsonbury have numerous species, as follows;—_Phascum bryoides var γ_, _Archidium phascoides_, _Fissidens adiantoides_, _Dicranum palustre_, _Hypnum molluscum_, _Brachythecium glareosum_, _Bryum bimum_, _Bryum pseudo-triquetrum_, _Bryum roseum_, and _Bryum Billarderii_; this last plant is exceedingly rare. It is the only known British locality, and it is not known to have been gathered elsewhere north of the Colosseum at Rome. _Brachythecium campestre_ is common in fields among grass, differing from _Brachythecium rutubulum_ by its gradually tapering, not suddenly acuminate leaves. _Bryum capillare ß flaccidum_ is found in a field in Newtimber valley. On walls _Tortula vinealis_, _Tortula revoluta_, _Tortula rupestris_, _Grimmia pulvinata_, _Orthotrichum saxatile_, _Orthotrichum diaphanum_, and _Rhyncostegium tenellum_, are luxuriant; but _Bryum sanguineum_ is rare. In Poynings springs _Mnium affine_ and _Hypnum filicinum_ are frequent. In the stubble fields at Aldrington are found _Acaulon Florkeanum_ and _Acaulon muticum_, and in the near hedge-banks, _Anacalypta Starkeana_, _Tortula insulana_, _Bryum Donianum_, _Scleropodium illecebrum_. Once, in November, 1858, the very rare fruit of _Eurynchium piliferum_ was gathered. Around Aldrington Basin are seen _Tortula ruralis_, _Tortula squarrosa_, _Trichostomum flavo-virens_, _Pottia Heimii_, _Pottia cavifolia δ gracilis_, _Physcomitrium pyriforme_, _Bryum cernuum_, _Bryum caespiticium_, _Bryum inclinatum_, _Bryum atropurpureum_, and _Rhyncostegium megapolitanum_; also fertile _Brachythecium albicans_ and _Camptothecium lutescens_. In woods are _Bryum torquescens_, _Orthotrichum Lyellii_, _Orthotrichum Ludwigii_, _Orthotrichum rupestre_, _Mnium hornum_, _Mnium rostratum_, _Mnium undulatum_, _Anomodon viticulosus_, _Neckera pumila_, _Neckera complanata_, _Isothecium myurum_, _Leucodon sciuroides_, _Cryphaea heteromalla_, _Leptodon Smithii_, (fruiting at Poynings), _Plagiothecium denticulatum_, _Plagiothecium sylvaticum_, _Eurynchium Swartzii_, and all the species of _Hylocomium_: the last mentioned abundantly, with capsules, at Clayton. On detached ash trees at the feet of the hills, _Orthotrichum tenellum_, _Orthotrichum pulchellum_, and _Tortula papillosa_ are not unfrequent. On beech stems about Woolsonbury, _Zygodon viridissimus_ fruits freely, and a most diminutive state of _Schistidium apocarpum_ is seen.
