SOUTHERN AFRICA.
.
By Charles Chupp and Ethel M. Doldge.
Published records of th e fioiius Cercospora iii S o u th ern Africa consist of a sm all n u m b e r o f descriptions of species on indigenous p la n ts a n d sc a tte re d references, in lists of p la n t diseases, to species on p la n ts in cultiv atio n . Ju d g in g from specim ens in th e C ryptogam ic H erb ariu m , P re to ria, th e la tte r have n o t alw ays l)een identified correctly. I n th e following pages 25 species on c u ltiv a te d p la n ts are listed ; these are m o stly cosm opolitan, or a t least occur com m only in tropical and sub tro p ical countries ; several are recorded for th e first tim e from S o u th ern Africa.
N o sy stem a tic collections have been m a d e o f fungi causing leaf spots on indigenous plants. Seven species of Cercospora were described by K alc h b ren n e r, Cooke a n d W in te r from m a te ria l collected by M acOw an a n d Medley W ood ; in la te r years, H . a n d P. Sydow described 10 species a n d Cercospora Oliniae w as described by V erw oerd a n d D ippenaar. A considerable q u a n tity of m a teria l in th e P re to ria H e rb a riu m h a d n o t been stu d ied ; u n fo rtu n a te ly m uch of this is in poor condition a n d could n o t be identified, b u t a n e x a m in a tio n o f leaves w ith lesions on which acervuli of Cercospora h a v e d3veloped has revealed a nu m b e r of unrecorded species. I t h as been deem ed advisable, therefore, to bring to g e th e r all records of Cercospora spp. know n to occur in S o u th ern Africa.
I n th e following pages 75 species arc listed ; 25 occur on c u ltiv a te d p la n ts a n d th e rein ain d er on p la n ts indigenous to S ou th A frica ; of th e la tte r 18 were previously recorded from S o u th Africa, 21 are species know n in o th e r p a r ts of th e world an d 10 are described as new. The species are arran g e d in alp h ab e tic al order.
