Floristik und Systematik der Phanerogamen. 237 



unreclaimed land is divided into maritime^ meadowland, mooiland;, and 

 inountain. In the maritime, an association with Plantago maritima and 

 P. Coronopus forms a characleristic low dense sward, and a list of asso- 

 ciates is given. The moorland Vegetation is tliat of drj' banks, stony 

 heath, marsh, bog^ rock, and cüff. Peat is most abundant between 300 

 and 460 metres. Callana Erica, Erica cinerea, and E. fetralix are 

 abundant but Daboccia polifolia and the species of Erica peculiar to the 

 mainland of Western Ireland vvere not found. The mountain- 

 flora is confined to Croaghmore, which from near its summit falls 

 into the sea as a precipice. On this cliff, many british arctic plants 

 were found. Silene acaulis is abundant, and its occurrence here brings 

 its ränge in Ireland considerably south. Lists of a dry Callana asso- 

 ciation, and of a Sphagnnm — Scirpus caespitosus one are given. The 

 complete list of plants found on Cläre Island (365 species and sub- 

 species) is given, along with notes on interesting plants. A crested form 

 of Osmunda regalis is figured. The flora is distinctiy calcifuge, and is 

 similar in character to that of adjacent Islands, Iniähbofin and 

 I n i s h a r k. 



This is the fiist attempt at a survey of this Island on Vegetation 

 lines, although it has been visited by several botanists. Achill is the 

 largest Island on the Irish coast; it includes about 50 sq. miles, and 

 consist ol gneiss, mica schist, and quartzite, with peat, drift, and blovvn 

 sand on the lower parts. The surface is hiily, rising in four places to 

 over 300 metres, and in two places to about 660 m.etres. The Vegetation 

 is wind-swept, with few trees and shrubs, and much bog and heath. 

 Farmland occupies 15 p. c. at present^ but in 1838 it covered about 

 tvvice this area. The seaboard Vegetation shows three characteristic 

 associations : 1. Plantago sward like that on Cläre Island. 2. Agrostis 

 vulgaris with other grasses and plants (given in a list) on low flat 

 sandy ground, 3. boggy flats with Jiincus maritimus. The moorland 

 consists of wet swamp with Carcx ; wet bog with Rhynchospora alba, 

 Drosera, etc.; deep peat with Eriophorum , Erica tetralix, Molinia, 

 Myrica, etc. 



Lists are given of plants occurring with Callana and Jiincus 

 squarrosus on summits above 610 metres, and with Callana, Saxifraga 

 umbrosa, and Vaccininm myrtillus on a rocky ridge. Lake Vegetation 

 occurs in numerous small lakes and pools, which give every gradation 

 from tidal lagoons to mountain tarns. The chief features are the few 

 species, and the northern arctic character, even at low altitudes. 416 

 species are given in a list of plants on the Island, and notes are given 

 on interesting species. The flora is strictly calcifuge. Compared with 

 Cläre Island, Achill presents a more uniform flora in spite of its 

 greater area, and it has fewer species peculiar to itself.

Wherever the two parent species grow thickly together the hybrid 

 occurs, but great variety of habit is noticeable in the latter and of those 

 observed on the salt-marshes near Bosham the majority favoured 

 L. humile. The hybrid has a very irregulär panicle and the spikes are
