II. Soi'T II -Western Region. — This region, as is well 

 l>;nown. differs in respect of climate (it has winter rains and 

 dry summers), from the rest of South Africa. The higher 

 plants characteristic of it are of a distinct schlerophyllous type, 

 including' a large numher of cricoid and other species which 

 occur in this region and nowhere else. It is interesting, there- 

 fore, to fnid that in addition to other Rryophyta this region has a 

 fair number of species common in it,.l)ut not known from else- 

 where, among which may he mentioned: — 



li'ardia hyf/roiiicfrica. Rliacocorpiis, -icvciai sps- 



I'issidciis pi II III OS us. Dicraiio!oiiia,

These intermingle freely with the more generally distributed 

 species. 



III. Eastern Region. — This region extends from Knysna 

 to Zululand, and from the ridge of the central escarpment on 

 the Drakensberg to the Indian Ocean, and has a rainfall of 20 

 to 30 inches per annum in most places. Inn up to 100 inches in 

 ^ome forest and mountavn localities. 



It includes most of the forests of South Africa, as also 

 most of the mountains, and is favoured in most localities with 

 more humid conditions than other parts of South Africa ; con- 

 sequently in it the Bryophvta, and especially the e]>ii)hytic forest 

 types are well represented. 



The variations of humidity, altitude, aspect, shade, vegeta- 

 tion and surface ai*e. however, \-erv marked and very rapid ; 

 from these causes a total change in the tv))e of moss-vegetation 

 often occurs within a few yards, and each side retains its 

 character as long- as conditions remain unaltered, usually in 

 accordance \\ith the higher veq-etation of the locality. 



In fhis region the brvoi)hvtic species of each of the other 

 regions intermingle, except such s|)ecies as are i>eculiar to each 

 of these; it has ccnsequentlv a very large numlxn" of such widely 

 distributed species, in addition to what are peculiar to itself. 



Many species onlv once collected have not yet been found 

 elsewhere, but that is ]>robably not always due to absence else-
