Near a stream on the one side of the field in question a marsh- 

 ilora oi the reed-swamp type was developed. The flat portion beyond 

 was covered with short herbage and characterised by the abundance 

 of Cynosurus cristatus ; between this area and the marsh two zones, 

 devoid of Cynosurus, can be traced, the one near the marsh with Ranun- 

 culus repens, but lacking R. acris, which is characteristic of the further 

 zone. Evidence is adduced to show that Cynosurus is a grass, charac- 

 teristic of poor soil, and that the humidity of the soil is not the gover- 

 ning factor of its distribution. The flat area was bounded on the other 

 side by a ditch, beyond which came a grass slope with northern expo- 

 sure; this differs from the Cy/z0s«r«s-region in being covered with taller 

 grasses (Deschampsia caespitosa, Alopecurus pratensis, Holcus lanatus), 

 which are mostly quite unrepresented in the former area. This is again 

 shown to be due to the Constitution of the soil and not to conditions of 

 moisture. Islands of Alopecurus occur in the Cynosurus-region and it is 

 probable that the former's area is increasing. In conclusion it is stated 

 as probable that the low-lying ground was occupied by a slow-flowing 

 stream which, owing to silling up in conjunction with local disturbances 

 connected with the drainage of the district, assumed first the character 

 of a marsh, and later conditions became sufficiently dry for the grasses 

 (Cynosurus) to obtain a foothold. F. E. Fritsch.

The following species are described : A. stenolepis nov. spec, differ- 

 ring from A. pedicellata in the characters of the involucre and in the 

 non-glandular pedicels; A. callilepis nov. spec, characterised by the 

 greenish and glossy involucres; A. acuminata nov. spec. with long, soft 

 foliage loosely clothing the stolons and old foliage perfectly glabrous.

Special attention was paid to the location of the physiographic line 

 which marks the Separation of the coastal piain from the hill region. 

 This line constitutes a barrier to many plant forms, and there is a great 

 difference in both the topography and flora between the two sides of the 

 line. A number of especially interesting species are listed and accom- 

 panied by notes, but no new species are described.
