= mass of soll, and m = air-dry soll (at 15° C.)- The second fac- 

 tor is w grams, obtained from, mass of soll (m) plus w, the amount 

 of water which the soil can still take in before being saturated. 

 Relative Saturation is (w—in) : w. This value is advocated as the 

 index of the „biological wetness" of a soil, but no actual determi- 

 nations are given for any specific plant Community.

Eyles, F., A Record of plants collected in Southern Rho- 

 desia. (Roy. Soc. S. Africa Meeting of 16th June 1915.) 



This record includes representatives of 160 Families, 869 Genera, 

 and 2397 Species, besides 112 Varieties. 



The flovvering plants are arranged on Dr. Engler's S3^stem as 

 set out in the Genera Siphonogamarum of Dr. C. G. de Dalla 

 Torre and Dr. H. Harms, 1900 — 1907. 



The ferns and fern allies are arranged in accordance with the 

 System of Engler and Prantl, as shewn in the Check List of 

 Flowering Plants and Ferns of the Transvaal and Swaziland 

 by J. Burtt-Davy and Mrs. Pott, 1911. 



With regard to the lower cryptogams, the arrangement is that 

 of Strasburger's Text Book of Botany, 1903.
