1 6 INFLUENCE OF CLIMATIC AND GEOLOGICAL CHANGES 



the coast, at Gerona. I have gathered it on the northern side, 

 at Amilie les Bains at a considerable altitude, under the shadow 

 of Mont Canigou, the highest mountain of the range, and 

 several miles inland. It follows the Mediterranean coast to 

 Narbonne, Montpellier, and Cannes, crosses the Italian frontier, 

 traverses East and West Liguria, Istria, Dalmatia, Greece, and 

 Turkey. Sir Joseph Hooker found it at Mount Djebel, near 

 Tangiers, also at Tetuan. It extends as far west as the Canary 

 Islands. 



II. Spartina Townsendi, H. and J. Groves (1881). Differs from 

 S. alterniflora in its leaves being shorter than the spike, the 

 lamina from five inches to one foot long, and jointed to the 

 sheath, ligule fimbriate instead of bristle-like ; glumes ciliated. 

 It has several of the characters of S. stricta, and appears to be 

 intermediate between both. S. Townsendi grows in company 

 with S. alterniflora on the mudflats of Southampton Water. It is 

 curious that it had evaded the notice of botanists until last year 

 (1899), wnen I found it in some abundance in one of the creeks 

 of Poole Harbour. 



The genus Spartina has a wide range both in the Old and New 

 Worlds. S. stricta is met with on the coasts and estuaries of 

 France and England, but not inland. Colmeiro, however, notes 

 it in the neighbourhood of Madrid. Asa Gray cites six American 

 species, two of which, S. stricta and 6*. alterniflora, are European. 

 It has not been yet found in Germany or Scandinavia. Its most 

 northern limit appears to be the Netherlands. Sir Joseph 

 Hooker found Spartina stricta in North Africa, near Tangiers. 



Setaria verticillata, Beauv. This grass, which Mr. H. J. 

 Goddard found at Upwey last year, does not reach farther 

 north than Lat. 58 N. It has a wide European range, the 

 Spanish Peninsula, the Eastern Pyrenees, Central and Southern 

 Russia, Hungary, Moldavia, Crete, the Ionian Islands, &c. 

 Sir Joseph Hooker found it near Tangiers, and at Mazagan, 

 on the north-west coast of Africa. Asa Gray reports it from 

 America, and Mr. Hemsley, from Burmah. It may have been 

 introduced with seed.
