ON UMBELLIFER 1938 
On Angelica silvestris. Not common. Uredospores, June 
and July; teleutospores, July—November. (Fig. 140.) 
Distinguished especially by the very bright yellow primary uredo-sori, 
and by the slightly larger uredospores than in allied species. Semadeni 
proved that it would grow also on Archangelica, but not on Athusa 
Cynapium or Peucedanum palustre. The primary uredo-sori should be 
compared with the ecidia of P..Smyrnii. P. Apii is also closely allied, 
but differs in the possession of a true cup-shaped ecidium.

P. Umbelizferarum and P. bullaria, p.p. 
Spermogones. Pale yellowish. 
Uredospores. Primary sori chiefly on the swollen nerves 
and petioles, elongated, as much as 
3 cm. long, dark-cinnamon, secondary 
hypophyllous or rarely epiphyllous, scat- 
tered, minute, punctiform, brown; spores 
globose to obovate, echinulate, brown, 
apex more or less thickened, 25—40 x 
18—28 p, with three or four germ-pores 
with swollen caps. 
Teleutospores. Sori similar, often Fig. 141. P. bullata, Te- 
confluent on the stems, long covered by ithe ee 
the epidermis, blackish-brown; spores 
oblong to obovate, rounded above, scarcely thickened, hardly 
constricted, slightly narrowed below, smooth, uniformly brown, 
30—45 x 18—24 w; pedicels hyaline, rather stout, deciduous. 
On Peucedanum palustre. Shrapwick Bay, Somerset, 1883 
(H. B. Waterfall). (Fig. 141.) 
This species is placed temporarily in the collective group, P. bullata 
Wint. All the forms which were included under that head by Plowright 
are now separated on morphological or biological grounds, but nothing is 
known as yet about the Puccinia on Peucedanum palustre, from the latter 
point of view. It is a close ally of P. Stlad.
