can be seen in the British Museum Herbarium which it is difficult 
to assign with certainty to either. 
I found this plant growing sparingly on the southern cliffs of 
Guernsey, near Petit Bot, on April 17th, 1899. These cliffs are 
about 800 ft. in height, the precipitous face varying from 100 to 
150 ft.; the remainder consists of a steep slope, overgrown in 
d everyw 
many part s with gorse, heather, and bracken, a ywhere 
covered with datioe except where the granite projects In 
boulders. M. scabrur ows on the lo art of this green 
slope, well away fr any houses or cultivated land; in no 
part of the island is one less likely to meet with an alien or 
casual.

-Charente- Perini and Vendée, but it is a rare plant. North of 
Vendée it only reappears on the coast of the oe certainly 
in South Holland, possibly in Belgium also. Oudemans (Flora van 
Nederland, te 475 (1874)) records it for fhe, neighbourhood ¢ 
also 
Katwijk, the dunes near Overveen, and ar Wassenaar and 
Scheveningen, in Nordwijk. These pera are bien in ad e

British Museum. Van Hall (Spec. Bot. 82 (1821), and Hlora Bagi 
ge ionalis i. 55 (1825)) records it, but gives no localities for 
Dumortier (Obser aoe sur les Graminées de la Flore 
Beigepid (1828) ) says, ‘‘ Plantam hance rarissimam mecum coml- 
municaverunt amiciss. van sont on van Hall,” but gives no localities: 
Parlatore (Flora Italica, i, 155 (1848) ) says, ‘Ei stata trovata in 
Belgio, in Francia,” &¢. Nyman gives Belgium only on Parlatore’s 
authority, an sn hie: modern Belgian Floras omit it. Husnot ie

The most noteworthy points about ‘M. scabrum in North-west 
Europe are, that it does not occur between Vendée and the Nether- 
lands, that it grows on sand, and that it is generally much taller

There are other plants which do not come further up the Fren¢ 
coast than Finistére, and yet are found in Guerns —e.g. Opnisho, us 
on sand are found on the rnsey cliffs—e.g. Romulea Column@
