142 PHANEROGAMIC COAST FLORA OF HOLLAND, 



34. Thelocarpon superellum, Nyl., in Flora, 1865, p. 261. On the 

 ground, Trefriw, N. Wales ( Wm. Phillips). 



35. Ferrucaria fluctigena, j!^yl., in Flora, 1875, p. 14, sp. n. On 

 maritime rocks, S. of England (Crombie)/f/^ ls\\. I.e. My duplicate 

 specimen (if such I had) seems to have gone astray. 



36. Ohryzum corniculatiim, Wallr., Fl., Cr. Germ., ii., p. 296. 

 Parasitic on thallus of Septogiuin microscopictim at Weston-super-Mare 

 (Wm. Joshua). As observed by Nylander in Flora, 1875, p. lO©, the 

 occurrence on this species of Septogium clearly shows the parasitic 

 character of Ohryzum. 



37. Endococcus triphractoides, Xyl., in litt., 1874 ; Cromb. in Gre- 

 villea iii., p. 24. Parasitic on dealbated portions of thallus of Lecidea 

 srotimdes, on Craig Tulloch, Blair Athole (Crombie), only a very 

 few apothecia present in the specimen where it occurred.

PHANERGGAMIC flora of the maritime SAND-HILLS 

 OF HOLLAND. 



The following catalogue of the Flowering Plants of the dunes of 

 the Netherlands coast is extracted from a paper by F. W. Eeden in 

 the " Nederlandsch Kundkundig Archief " for 1874. It inhere re- 

 produced for the sake of comparison with the Flora of the exactly 

 opposite shores of our Eastern Counties (Norfolk, Suffolk, Essex), 

 which, although the sand-hills nowhere attain the dimensions of those 

 in Holland, present many features of similarity with that country. 

 The limits of the district treated of are thus given by the author : -^ 

 ''This list includes the Flora of all the sand-hills (' duinen') of the 

 Netherlands, both on the islands and on the mainland of the provinces 

 of North and South Halland, and on Voorne, Walcheren, andSchouwen. 

 Among them are, therefore, included the sea-dunes (' zeeduinen ') 

 which extend along the coast on the west, and the inland dunes 

 (' brunenduinen ') which lie in more or less connected lines from the 

 Hague to Alkmaar. To these inland dunes belong the wood at the 

 Hague, the dunes of Lisse and Hillegom, Beunebroek and Heem- 

 steede, Kennemerland, the Haarlem wood, the Schapen dunes near 

 Bloemendaal, the dunes of Santpoort and Heilo. The river dunes in 

 Guelderland and the diluvial sand-hills of Gooiland and the country- 

 lying eastward from this are not included in the Flora."* 



* The coast-flora of Belgium has been studied by Dumortier (Bulletin de la 

 Soc. Bot. de Belgique, vol. vii.). For an account of the plants of the islands of 

 East Friesland which directly continue to the north-east those of Holland, see 

 Noldeke's paper in the " Abhandlungen " of the Natural History Society of 

 Bremen for 1872, pp. 93—198. A catalogue of the plants of Heligoland will be 

 found in HaUier'w " Nordseesludien " (18eS), pp. 158— 168. — [^rf. Journ.
