man}' places being replaced by various shrubs. Succulents are very rare. In the mountain 

 formation there is a grc.it difference between the vegetation of .sunny and of shady slopes 

 Often on shady slopes bush and scrub occur. On the mount. tins there appear to be roughly 

 four formations: (!) L <icosidea sericea in the kloofs. (2) The mesophytic Arundinaria 

 tesselata formation, (3] The less mesophytic tussock grass formation, and O) the xerophytic 

 ericoid shrub formation. — E. P. Phillip

 36:636-645. 1 fig. 1918. [Mar., 1919]. — Plantago maritima was observed on soils containing 

 chlorides, sulphates, carbonates and possibly silicates. In the places where it stands out- 

 side its normal associations it is derived from forms originally typical halophytes. However, 

 the chief occurrence of Plantago maritima is in salt soil with typical salt plants. — Ernst 

 Artschwager.

 (an island off the west coast of southern Sweden). I. Composition of the vegetation.] [Swed- 

 ish.] Map. Bot. Notiser 1918:265-286. 1918.— The vegetation is divided between the shore- 

 vegetation and the forest. The former is subdivided into the vegetation of the cliff-shores 

 and of the sand-beaches, and the latter into the oak- and beech-woods and the alder-swamps. 

 All except the woods proper show zonations depending upon the depth of the permanent 

 moisture of ground-water, the percent of salt present, and the amount of light. Short de- 

 scriptions of the vegetation of each zone are given, as well as that of the small islets surround- 

 ing Hallands Vadero. These islets have only a cliff -shore vegetation. — P. A. Rydberg.

 Jour. Amer. Soc. Agron. 10: 29-31. 1 pi. Jan., 1918. — It has generally been held that Rumex 

 acetosella grows best in an acid soil; hence it has been used as an indicator of acid land. Since 

 there is ample experimental evidence that this plant can thrive in calcareous media, it is 

 probable that its general absence from such soils in nature is due to its relative impotence 

 in competition. [See also Bot. Absts. 2, Entry 311.] — H. C. Cowles. 



294. Morris, George. Reconnaissance of the plant associations in the neighborhood of 

 Newbury, Berkshire. Jour. Ecol. 7:65-70. 2 fig. May, 1919. — Notes are given upon an 

 area with varied substratum having a vegetation much disturbed by man's activities and 

 including forests in which Quercus robur, Fagus silvatica, Acer pseudo-platanus , Betula, 

 and Pinus silvestris are prominent elements. There are also areas of alderwood, Alnus 

 glutinosa, and of heaths dominated by Calluna and Ulex. Some conclusions are drawn as 

 to the probable primitive vegetation. — Geo. D. Fuller.

 listed and attention is given to the density of the plankton, composition and distribution.
