better developed, and the teleutuspores are plainly but not so densely 
reticulate. Klebahn proved by cultures that P. Pimpinellae is distinct 
from P. Chaerophylli, and Semadeni similarly proved its difference from 
that species and from P. Heraclei; the latter showed (Centralbl. £ Bakt. 
2. xill. 215) that it could be transferred to other species of the genus 
Pimpinetia, but not to other genera of the Umbelliferae.

over the whole surface among the ecidia. 
Aicidiospores. Bcidia hypophyllous, or a few epiphyllous, 
uniformly scattered, cup-shaped,

Teleutospores. Sori amphigenous, minute, scattered, round-

covered by the epidermis, at length naked, blackish-brown ;

teleutospores, Walton-on-the-Naze, August, 1887. (Fig. 187.) 
The uredospores were found in small quantities among the teleuto- 
spores. Fischer says that the affected plants usually bear ecidia on every 
leaf, the leaves are narrower and paler, and the plants do not flower; the
