186 WORLD-DISTRIBUTION OF THE BRITISH CARYOPHYLLACE^. 



III. Arena7-ia tenuifolla. 



II. Arenaria verna. — Our plant widely spread in Siberia, Gebler ! 

 Tiirczaiiinow ! etc. The N. American A. p'opinqua, Eichardson, 

 seems quite identical with our plant. It has a range from Kamtchatka 

 and Greenland to the Rocky Mountains, The Arctic A. Ross'ii comes 

 in between this and rubella, so that, in high latitudes, the range of 

 forms is connected very closely. 



VIII. Arenaria rubella. — The Scandinavian ^./iir^a, Hartm., appears 

 to be a variety with a more robust habit and more hairy stems than 

 the Scotch specimens, and I fail to separate from this the Swiss A. 

 verna, var. subnivalis, of Hegetschweiler. 



VI. Arenaria uUginosa, — Behring's Straits, C Wright! Rocky 

 Mountains, Druimnond ! 



III. Arenaria trinervis. — M. pentandra, Gay, a variety frequent in 

 the south of Europe. The Greenland plant probably M. lateriflora. 



Ill, Holosteum umbellatmn. 



II. Stellaria nemorum. — Reaches all through Siberia to Manchuria, 

 and reappears in N.W. Mexico, Seemann ! though apparently not 

 known northward, 



I. Stellaria media. — Now a common weed everywhere in temperate 

 regions. 



III. Stellaria Holostea. 



I. Stellaria glauca. — Widely spread in Australia, with several varie- 

 ties. The Greenland plant probably S. longipes, which is extremely 

 like glauca in habit, but diifers in the seeds, 



III. Siellaria graminea. — Reaches North China. 



II. Stellaria uliginosa. 



VI. Stellaria cerastoides. — Gathered by the Moldavian missionaries 

 in Labrador. 



III. Cerastiiim aqiiaticum. — Reaches Formosa, Oldham ! Japan and 

 Loochoo, Wright ! and frequent in the north-west Himalayas. 



I. Cerastium glomeratum. — South Africa, Brege ! Monte Video, Isa- 

 belle ! Australia, Adamson ! New Zealand, Colenso ! 



I. Cerastium triviale. — Chili, C. Gay ! Falkland Isles, Dr. Hooker ! 

 Cape Colony, Sutherland! Sandwich Isles, HilUbrand ! Tristan 

 d'Acunha, M'GilUvray ! 



IV. Cerastium semidecandrnm. 



V. Cerastium tetrandrum..
