The aecidia are rarely seen in the Transvaal, and their place would appear 
to be taken by uredospores, which occur commonly on Transvaal material, 
and which have not hitherto been recorded for this species. 
7. Puccinia Pienaarii Pole Evans, n.sp. 
Aecidiis amphigenis in villo nidulantibus, solitariis vel gregariis, pallidis, 
margine laciniato ; aecidiosporis angulato-globosis vel ellipsoideis, subtiliter 
verruculosis,subhyalinis, 21-30 x 15-22/x; soris teleutosporiferis amphigenis, 
sine maculis, saepe aecidiis immixtis, sparsis vel gregariis, rotundatis, ca. 
1 mm. diam. primo tomento folii tectis, dein nudis, pulverulentis, brunneo- 
atris ; teleutosporis difformibus, ellipsoideis vel oblongis, apice rotundatis 
vel truncatis, medio parum constrictis, basi plerumcjue rotundatis, ad 
marginem irregulariter incrassatis (usque 7 /x), flavo-brunneis, levibus, 
33-48 X 18-27 /x; pedicello hyalino, brevi, caduco. 
On leaves of Helichrysum sp. Paardeplaats, Lydenburg District (P. J. 
Pienaar), 2:4: 1911. (Pole Evans, 1489.) Plate XLYII, fig. 9. 
This species is remarkable for the irregularly thickened walls of the 
teleutospores. In some cases the walls might well be described as being 
flanged. 
Aecidiospores.- — Aecidia amphigenous embedded in pubescence, solitary 
or gregarious, pallid, with a laciniate margin ; spores angular- globose or 
ellipsoid, delicately verruculose, subhyaline, 21-30 x 15-22 /x. 
Teleutospores. — Sori amphigenous, without spots, often mingled with the 
aecidia, scattered or gregarious, rotund, about 1 mm. diam., at first covered 
by the leaf pubescence, afterwards exposed, pulverulent, brownish black ; 
spores of unusual shape, ellipsoid or oblong, rounded at the apex or 
truncated, usually a little constricted at the middle, mostly rounded at the 
base, irregularly thickened at the margins (up to 7 />t), yellowish-brown, 
smooth, 33-48 x 18-27 /x; pedicel hyaline, short, caducous.
