1863.] BELGIAN BOTANY. 387 



On the grassy plots of tlie inner dnnes we fonnd in abundance 

 Thalicirum minus, a species met with everywhere from Knocke 

 to the French frontiers. Between Mariakerke and Middelkerke 

 Trifolium scabrum, Medicago minima, Plantayo Coronopus, 

 scarcely visible in the grass ; and Ctrastiiim tetrandrum mixed 

 with fine specimens of CocJilearia Dunica. Here and there were 

 a few solitary plants of Asparagus officinalis and small tnfts of 

 Arahis sagittata ; then we met with enormous patches of Sedum 

 acre, which^ with the Uttorale variety of Galium verum, com- 

 pletely carpeted the dunes. Among the G. verum and G. Mol- 

 lugo, which were very abundant, we sa wjiere anjLthere a hybrid 

 which derived its being from these two species. Our attention 

 was drawn to a curious form of Erodmm cicutarium., with small 

 pale flowers, which I think Mr. Jordan has termed his E. Bore- 

 anum. In the gaps made by the sand, and in the hollows in the 

 roads, we remarked a j'ojnist variety of the Arenaria se7'jjy/lifolia, 

 which constitutes the A. Lloydiij J ord. 



On arriving at Middelkerke we espied on the sandy banks of 

 a little garden, the rare Carduus tenuiflorus, which we saw again 

 on that and the following days along the coast in the neighbouring 

 villages. Another remarkable synanthera, but common in th.at 

 part, is the Onopordon Acanthium, whose majestic habit is more 

 like that of an exotic plant than of an indigenous species. In 

 another garden we obtained Fumaria densiflora, DC. [E. mi- 

 crantlia, Lagasc), wdiich was found by Professor Crepin ; a very 

 beautiful species, and quite new to the general flora of this 

 country. 



A little beyond the village we came to a boggy meadow, which 

 appeared to be the rendezvous of several interesting species, — 

 Sagina nodosa, Helosciadium repens, Apium graveolens, Glaux 

 maritima, Cineraria palustris, Herminium Monorchis, Epipactis 

 palusiris, Juncus ohtusiflorus, Scirpus compressus, Care.v Pseudo- 

 cyperus, Schoenus nigricans, Alopecurus fulvus, Lem.na arrhiza. 



Here and there along the coast the Cynoglossum officinale, 

 Sisymbrium Sophia, and Anthriscus vulgaris appeared. As far as 

 the environs of Westende avc met with nothing but the common 

 species already cited, to which however must be added Lycopsis ar- 

 vensis (common everywhere), Asperula Cynanchica, Silene nutans, 

 Alpena pubescens, Bryonia dioica, and Car ex trinervis. As regards 

 the last-named species, well distributed on the western borders of
