BY J. E. BAGNALL, A.L.S.
In describing the rarer Mosses, Hepatics and Lichens, to be found within the district, the materials at command are not sufficient to admit of so minute an analysis of distribution as that given for the flowering plants in the preceding pages. For the mosses four sub-districts will be adopted: I. Warwick, Tame; II. Warwick, Avon; III. Worcester; IV. Stafford. For the Hepatics and Lichens, the enumeration will be restricted to Warwick only; information for Worcester and Stafford not being within reach. The nomenclature of the Mosses and Hepatics is that of the “London Catalogue of British Mosses and Hepatics,” 2nd Edit., 1881. The nomenclature of the Lichens is that of “The Lichen Flora,” of the Revd. W. A. Leighton, 1871.
MOSSES.
The Moss Flora of the whole district under review, so far as records are available, is about 272 species and varieties; that of Warwickshire alone being about 261. Its comparative poverty may be attributed, partly to the absence of great elevations, partly to the prevalence of smoke over large portions of the district, and partly to the draining of bogs and marshes, and reclamation of heath lands.
I. Warwick, Tame.—This sub-district includes that portion of the country watered by the Tame and its affluents, the Cole, Blythe, Bourne, and Anker. The following are the more noticeable mosses.
Sphagnum fimbriatum, S. squarrosum, S. rubellum, S. papillosum, S. cymbifolium, var. squarrosulum; Systegium crispum; *Dicranum spurium, D. fuscescens, D. majus; Campylopus flexuosus; Archidium phascoides; Pleuridium alternifolium; Leucobryum glaucum; Sphærangium muticum; Pottia minutula; Trichostomum tophaceum; Tortula aloides, T. marginata, T. rigidula, T. spadicea, T. insulana, T. tortuosa, T. subulata, T. papillosa; Encalypta streptocarpa; Racomitrium canescens; Zygodon viridissimus; Ulota intermedia; Ephemerum serratum; Funaria fasciculare; Bryum pallescens, B. roseum; Mnium rostratum, M. stellare, M. subglobosum; Polytrichum gracile; Fissidens adiantoides, F. exilis; Leucodon sciuroides; Amblyodon dealbatus; Philonotis fontana; Homalia trichomanoides; *Hedwigia ciliata; Brachythecium albicans; Eurhynchium speciosum, E. Teesdalii; Plagiothecium sylvaticum, P. elegans, P. latebricola; Amblestegium fluviatile; Hypnum commutatum, H. exannulatum; H. Cossoni, H. vernicosum, H. falcatum, H. giganteum, H. stramineum, H. revolvens.
II. Warwick, Avon.—This sub-district includes that portion of Avon within the area, and its affluents, the Sow, Alne, and Arrow. The following are the more rare mosses:—
Sphagnum auriculatum, S. subsecundum; Gymnostomum tenue; Dicranum montanum; D. scoparium; Campylopus pyriformis; Pottia intermedia, P. cavifolia, var. incana; Tortula rigida, T. ambigua, T. atro-virens, T. Brebissoni, T. lævipila, T. intermedia, T. papillosa; Grimmia crinita; Orthotrichum saxatile, O. stramineum, O. tenellum, O. leiocarpum, O. Lyelii, O. rivulare; Leptobryum pyriforme; Bryum pendulum, B. murale; Mnium undulatum; Polytrichum formosum; Fissidens Lylei, F. incurvus, F. pusillus, F. inconstans, F. tamarindifolius; Cryphæa heteromalla; Anomodon viticulosum; Thamnium alopecurum; Climacium dendroides; Camptothecium lutescens; Scleropodium cæspitosum, S. illecebrum; Brachythecium rivulare; Eurhynchium pumilum; Rhynchostegium tenellum; Hypnum Lindbergii, H. stellatum, H. chrysophyllum, H. cordifolium, H. splendens, H. brevirostre, H. loreum, H. palustre.
III. Worcester.—The moss flora of this sub-district has not been published; but the moss herbaria of Mr. Mathews and the writer afford records of about 127 species. Many of these have already been recorded for Warwick, and are therefore omitted here. The following, which are mainly from the Stour sub-district, are the more noteworthy:—
Sphagnum auriculatum; S. cuspidatum, S. intermedium; Dicranum scoparium; Leucobryum glaucum; Pleuridium nitidum; Pottia Wilsoni, P. intermedia; Tortula cuneifolia, T. convoluta; Encalypta vulgaris, E. streptocarpa; Racomitrium aciculare, R. lanuginosum, R. fasiculare; Ptychomitrium polyphyllum; Ulota intermedia; Orthotrichum Lyellii; Ephemerum serratum; Physcomitrella patens; Amblyodon dealbatus; Philonotis fontana; Leptobryum pyriforme; Bryum pendulum, B. roseum; Mnium stellare; Aulacomnium palustre; Fissidens exilis, F. adiantoides; Fontinalis antipyretica; Neckera crispa; Homalia trichomanoides; Pterygophyllum lucens; Climacium dendroides; Brachythecium populeum; Rhynchostegium murale; Hypnum commutatum, H. palustre, H. chrysophyllum; *H. scorpioides.
