18 ECOLOGY, PLANT GEOGRAPHY [BoT. Absts., Vol. VIII, 



137. Nelson, James C. A noteworthy grass. Amer. Bot. 26: 10-12. Fig. 1. 1920. — 

 Coleanthus subtilis described from the mountains of Bohemia in 1816 was first observed in 

 America at Searles Island, in the Columbia river near the mouth of the Willamette in 1875. 

 It has since been found at Hood River, Oregon, White Salmon and Bingen, Washington. 

 Recently (Oct. 1919) it was reported from Hayden Island opposite Vancouver, Washington, 

 by the author. The mature plant is only a few centimeters in length and the suggestion is 

 made that it may be a native to America frequently overlooked because of its size and late- 

 ness in appearing. — W. N. Clute. 



138. Nelson, James C. Tilia europaea in Oregon. Torrej'a 20: 31-32. 1920. — A speci- 

 men of Tilia europaea L. about 40 feet high was found on June 19, 1919, in the Calapooia 

 Mountains along Smith River, near Gunter, Douglas County, Oregon, apparently perfectly 

 established, and probably a relic of cultivation by an early apiarist, although the mountain- 

 forest was apparently unbroken. — /. C. Nelson. 



139. Palmer, Ernest J. The canyon flora of the Edwards Plateau of Texas. Jour. Arnold 

 Arboretum 1 : 233-239. 1920. — The author gives an account of the physiography of the 

 Edwards Plateau and of the general character of its vegetation, which is xerophytic except 

 along the water courses. Particular attention is drawn to the occurrence of Taxodium 

 distichum along the lower river courses. The most remarkable feature of the flora is the 

 presence in the upper canyons of small colonies of many species belonging to the Gulf and 

 Atlantic coastal plain flora. These colonies are explained as relics of a former extension of 

 the coastal plain forest across the Edwards Plateau possibly almost to the base of the Rocky 

 Mountains. After the elevation of the region had taken place about the close of the Tertiary 

 period, the climatic changes caused the gradual disappearance of the forest, which was replaced 

 by the semi-desert flora of the southwest and of northern Mexico except in sheltered spots 

 in the canyons where vestiges of the original flora persisted. — Alfred Rehder.

 dian Field-Nat. 33: 114-117. 1919. — The more characteristic plant species of various ecologi- 

 cal regions of an island of the St. Lawrence River are enumerated. Several species of Carex 

 receive special mention. — W. H. Emig.

146. Wilson, E. H. The Liukiu Islands and their ligneous vegetation. Jour. Arnold 

 Arboretum 1 : 171-186. 1920. — An account of the woody plants of the Liukiu Islands is 

 given, preceded by introductory notes on the geography, . history, and population of the 

 islands. The flora of the northern group of islands is related to that of Japan, that of the 

 southern group to the flora of Formosa. The vegetation is characterized by the evergreen 

 shining foliage of most of the woody plants and by the presence of Mangrove-like trees, Cycas
