70 PRESIDENTIAL ADDRESS SECTION C. 



We need such lists tor the Orange Free State. Basutoland, 

 the whole " Eastern Province '" area, the Cai)e Midlands. British 

 Bechuanaland, the Bechuanaland I'roiectorate and the S.W. 

 Protectorate, and parts of Rhodesia, especially the vicinity of 

 Bulawayo and the rest of Alatabeleland. 



It will be noted that none of tiie published Lists covers 

 the entire area of any one of the six suggested Floral areas. 

 When these have been defined by the suggested conference of 

 Ixttanists, one of the first stej^s might be to revise and extend 

 them to cover the accepted areas. 



The SroROPiivTA. 



With reference to the less highly developed forms of plant- 

 life, Mr. T. R. Sim has given us a second edition of his " Pteri- 

 dophyta of South Africa," and is now engaged on a " Handbook 

 to the Bryophyta." Professor W^ager has recently pul)lished .i 

 check-list of the Mosses of South Africa. 



Mr. Pole Evans and his staff in the Department of Agri- 

 culture, Pretoria, are at work on the mycology of South Africa, 

 especially in its relation to plant pathology. 



Miss Duthie is engaged on the Myxomycetes. 



The late Dr. Becker made a large collection of our Marine 

 Algae, but we need a descriptive account of them, for the guidance 

 of teachers and others interested in this attractive branch as well 

 as for the use of those who would utilize the kelps for industrial 

 purposes. 



The Fresh-water Algje, Characese, Lichenes. Diatomacese, 

 and the Basidiomycetes and other gr>)ups of fungi, oft'er inviting 

 fields of research for those who are training in botany in our 

 universities and colleges.

(Jtiiek Lines of Survey Work. 

 Although so much remains to be done on the taxonomic 

 side, so much has already been accomi)lished that we are al)lc 

 to proceed with other lines of the surxey without too serious 

 hindrance from lack' of names. When, in the course of our 

 work we find an unnamed species of im]K')rtance, Ave can — if un- 

 Ijrepared to name it oin-selves — submit it to one of the larger 

 herbaria. Let us therefore consider, for a moment, the other 

 directions wdiich the survey should take. 



The Economic Plant Survey. 



The object of the Economic branch of the survey is to find 

 out the relations of our flora to mankind ; both the useful and 

 the injurious j)roperties of the species of which it is composed. 

 The folknving are some of the more inii)ortant <|uestions which 

 this branch of the survey is expected to answer: — 



I. Pasture Plants.— -Which of the native grasses and other 

 plants are eaten bv livestcick? ^^^herc do they <xx-ur, and in 

 what nuantities? What is their relativ- feeding value? Which
