which are known to occur in South Africa will be included whether they be 
aliens or not, and every species of which specimens are available will be 
figured in its essential parts. 
All the spores are drawn to the same magnification of 600 times unless 
it is stated to the contrary. 
1. The Species of Fuccinia on Compositae. 
Sydow's Monographia TJredinearum, published in 1904, records seven 
species of Puccinia on Compositae from South Africa. 
Of these, Puccinia Stohaeae MacOwan, P. Kalchhre^meri De Toni, P. 
Prhitziae Thuem., P. aecidiiformis Thuem., and P. oedipus Cke., are 
recorded from South Africa only, while P. MacOwani Wint. is reported from 
South and Central Africa, and P. africana Cke. from Abyssinia, Madagascar, 
South and Tropical Africa. 
The present paper records fourteen species of Puccinia on Compositae in 
South Africa, and describes four new sj^ecies. Of the remainder, Puccinia 
vernonicola P. Henn. has previously been recorded from Tropical East 
Africa, while P. Chrysanthemi Roze and P. Hypochoeridis Oud. have a 
wide distribution. 
The descriptions of the species on Compositae are as follows :

Aecidiospores. — Aecidia hypophyllous, on orbicular spots up to \ cm. 
diam., sometimes confluent yellow-brownish, aggregated in groups 3-5, 
white, margin fimbriate-lacerate ; spores globose or subglobose, angular, 
verruculose, hyaline, somewhat yellowish, 21-36 fx diam. 
Uredospores. — Sori amphigenous, hidden in the lower surface under 
the araneose pubescence of the leaf, pulverulent on the upper surface, 
scattered or running together in irregular clusters, black-fuscous ; spores 
globose or ellipsoid-globose, strongly echinulate, fuscous-brownish, 25-40 /u 
diam . 
Teleutospores. — Sori mostly hypophyllous, scattered or in groups of 
4-7, rotund, black, about 1 mm. in diam. ; spores ellipsoid or oblong strongly 
thickened at the apex (up to 14 p) and mostly more or less lengthened, rarely 
subrotund, slightly constricted at the middle, mostly rounded at the base, 
rarely attenuated in the pedicel, smooth, fuscous, 40-68 x 21-32 /x ; pedicel 
hyaline, persistent, thick, slightly thickened at the base, up to 124 /x long. 
First recorded on leaves of Berhheya membranifolia and speciosa near 
Somerset East (MacOwan).
