The Irish Naturalist. 



September, 



common in this district. Carex Hudsonii (previously 

 unrecorded from Clare), is also characteristic and abundant, 

 accompanied by C. vesicaria. Butomus umbellatus is remarkably 

 abundant and widespread, and other characteristic marginal 

 plants are Ra?itmculus Li?igua, CE?ia?ithe crocata and CE. 

 Phellandriuvi, Ritinex Hydrolapathum, and three Nasturtiums 

 {N, sylvestre, N. palusti^e, and N. ainphibium), the first-named 

 sometimes in great profusion. Of hydrophytes proper, 

 Potaviogeton luce7is is the most conspicuous plant, and in 

 shallow water it is replaced by P. heterophyllus (unrecorded 

 for Clare), and P. plantagineus. The pools yield great masses 

 of Characese (C. polyacaiitha^ C. fragilis, C. hispida), the first- 

 named (new to Clare) being the most abundant. Where the 

 bottom is peaty, Lcinna trisulca and Spaigariium viiiiimum 

 occur in quantity, WitXi Elodea canadensis. In marshy meadows 

 07'chis i?icarnata (unrecorded from Clare), is a frequent 

 ingredient, with Viola canina occasionally. 



The flora of the inhabited and cultivated areas comprises 

 an unusually small proportion of the total flora, on account 

 of the small percentage of arable land and thinness of the 

 population. Trees and woods are rare. Ash dominates the 

 patches of native wood, and Hazel is widely spread. Hypericum 

 diibium was almost the only uncommon woodland plant noted ; 

 it is of frequent occurrence. In damp pastures Habenarias 

 (//. co7iopsea, viridis, bipolia, and chloroleuca), and in dry pastures 

 Orchis py^nmidalis are conspicuous. By roadsides, Sc7iiebiera 

 didyma and 6*. coronopus, Veronica agresiis and V. polita, 

 Origainmi and Ve7'be7ia, are familiar sights, with Co7ivolvulus 

 a7ve7isis occasionall}^ The most conspicuous weed of 

 cultivated land is B7'assica alba ; with it one notices Ce7itau7xa 

 Scabiosa, and three Poppies {P. Rha^as, P. dubiuni, and P. 

 hyb7 idu77i). 



It was with some surprise that I found that as many as 21 

 of the plants noted are additions to the well-worked Clare 

 flora. These are : — 



Thahctrum flavum. JSaHx fragilis. 



Ranunculus peltatus. fpurpurea. 



*Arenaria tenuifolia. Orchis Morio. 



Myriopliyllum verticillatum. incarnata. 



spicatuni. 

 *Petroseliiuuii sativum. 

 Betula verrucosa. 



Sparganium affine. 

 I^emna polyrhiza.
