Puccinia Campanulaceae. 149 



0. Spermogonia slightly raised, with projecting paraphyses, honey 



coloured, in groups. 



Spermatia numerous, hyaline, ellipsoid, 5-6 x 3 p. 



1. Aecidia amphigenous, rounded or ovate, scattered or densely 



gregarious and occupying the entire surface of the leaves or 

 petioles, at first covered by the epidermis, then free and rupturing 

 like a broken blister, vesicular, ochraceous ; pseudoperidial cells, 

 oval to oblong, covered with spines, loosely connected, 30-40 x 

 18-25 p. 



Aecidiospores irregularly globose, sub-angular or ellipsoid, finely 

 echinulate, with distinct wall, ochraceous, 18-22 p. or 22-28 x 

 18-20 p. 



III. Teleutosori on under surface, numerous, bullate, then girt by the 

 ruptured epidermis .so that they resemble little Pezizae. 



Teleutospores cylindric to sub-clavate, elongated, yellow, 

 thickened apex (9-10 ju), rounded or truncate, deeply constricted 

 at septum 56-70 x 15-26 /i, average 60 x 24, occasionally bi* 

 and tri- septate when they may reach a length of 80 p ; upper cell 

 generally broader than lower ; lower cell generally cylindrical, and 

 may taper slightly towards pedicel ; pedicel hyaline, short, stout, 

 7-13 jj. broad.

Teleutospores on leaves of Lobelia anceps L. 



South Australia Port Lincoln, Nov., 1852 (C. Wilhelmi), 

 (Berkeley 2 ). 



The aecidium was first determined by Thuemen on a specimen of 

 Pratia platycalyx sent by the late Baron von Mueller from Colac, and named 

 A. lobeliae. Then Berkeley received a specimen from the same source on 

 P. pedunculata which he named A. microstomum. 



I have examined portions of the original material of both these 

 specimens, and as a rule it is difficult to detect a peredial wall even in fine 

 sections, so mueh so that they were as first taken for caeomata. But there is 

 occasionally a loosely fitting layer of surrounding cells, so that we may 

 regard them as aecidia. The aecidial stage is given in connexion with the 

 teleuto stage since, although not found actually together, they occur separately 

 on the same species, Lobelia anceps. 



The teleutospore is occasionally tri-septate, and is then slightly curved, 

 and the lower septum oblique. 



The description of the* teleuto stage is drawn up from original specimens 

 in the National Herbarium, named in Berkeley's handwriting.
