common as a weed of sandy cultivated ground." This form is, 

 however, a native of the short close turf on the coast of Guernsey, 

 being especially abundant about Petit Bot Bay and L'Ancresse, 

 Guernsey, and also occurring in Alderney and Jersey. Mr. Mar- 

 quand has known it for many years, and the Eev. E. F. Linton 

 (see his note, p. 380) has had it in cultivation. It is one of the 

 earliest species to flower, being in full bloom in February and 

 March. The habit is that of Sagina procumbens for which, in the 

 flowerless condition, the rosettes, from 1 to 3 in. across, might be 

 mistaken. The seeds are papillate; the plant is more or less 

 glandular, but less conspicuously so than in the type. 



Spergularia rubra L. Abundant in Jersey, and often a very 

 luxuriant plant. — S. rupestris Lebel. Common in Jersey, Guernsey, 

 and Alderney, and forming a large part of the vegetation of Berhou 

 (Marquand), and usually very glandular. In cultivation the plant 

 is much altered in appearance, losing its turgidity, and becoming 

 a slender straggling plant. — S. neglecta Syme. Corbi^re Eocks ; 

 only one station given in the Jersey Flora. — *$. atheniensin 

 Aschers. (= S. diandra Boiss. var. atheniensis mihi). Near St. 

 Helier's, Jersey, on mobile sand. This plant, which has a wide 

 range of distribution along the Mediterranean coast of Europe, 

 from Phaleron, near Athens, to Cadiz, does not appear to have 

 been recorded for the north-western coast of France. It differs 

 from S. rubra by the stipules being blunt and broadly triangular 

 and dull, not narrow-lanceolate and silvery white in colour. The 

 central rosette of leaves characteristic of S. rubra is also lacking ; 

 the seeds are larger; the capsule also differs in shape. From 

 S. neglecta it may be known by its much smaller capsule, more 

 slender branches, and different habit. 



Polycarpon tetraphyllum L. This plant, as Mr, Lester-Garland 

 points out, exists under two different modifications. The one, 

 which may be taken as the type, is found by the waysides, at the 

 base of walls, and in cultivated ground, and is the much larger 

 plant, with larger and darker-coloured leaves, and more numerous 

 flowers. The second is a much smaller plant, of a yellowish -red 

 tint, with fewer flowers, and a very different habit. This is found 

 on the sand-dunes and other dry uncultivated places. I was too 

 late to find it in flower in 1906, and too early in 1907, but it has 

 much the appearance of P. alsinifolium DC, which is said to 

 differ in the number of the stamens, having five, while P. tetra- 

 phyllum has three only. Corbi6re admits it as a native of the 

 sand-dunes in Normandy, but Rouy & Foucaud (Fl. France, iii. 

 313) say it is limited to the Mediterranean. In Alderney a less 

 extreme form (P. tetraphyllum var. densum Rouy & Foucaud) was 

 found on the dunes. 



Hypericum linariifolium Vahl. Fiquet Bay. — H. humifusum 

 L. Occurs often as a larger plant with broader leaves than 

 the common English form. I saw no specimens suggesting 



hybridity. 



Lavatera sylvestris Brot. A plant on the railway near Mill- 

 brook, Jersey/ and another near the Grande Havre, Guernsey ;
