Aecidium Leguminosae. 199 



he kindly sent me. The spores in both cases are very finely echinulate, and 

 in the West Australian specimens they are 18-23 x 15-18 p, while in the 

 other they are 18-28 x 12-17 p. 



On the stems of B. cinerea there are oval to lenticular swellings, some- 

 times half an inch long, separate or close together, with dark purplish 

 border, and often becoming depressed in the centre. On the leaf -stalks the 

 swelling may completely surround them, and on the leaf there are brown 

 raised orbicular spots, with aecidia on both surfaces, but sparingly on upper. 

 On the flower-stalks the swellings are similar to those on the leaf-stalks, and 

 on the legumes large circular or irregular patches are formed on margins and 

 both valves.

Platylobium. 



140. Aecidium platylobii Me Alp. 



0. Spermogonia honey-coloured, minute, scattered, either associated 



with or on opposite side to aecidia. 



Spermatia very numerous, hyaline, cylindrical, 3 x 1 p. 



1. Aecidia on pallid spots or on swellings on pods, amphigenous, in 



small groups or in dense clusters, deep orange ; pseudoperidia 

 cylindrical, white, with small portion inserted in matrix, margin 

 finely toothed, up to 1 mm. long. 



Aecidiospores orange, elliptic to sub-angular, finely warted, 

 21-25 x 14-18 11. 

 On leaves and legumes of Platylobium formosum Sm. 



Victoria Murramurrangbong Ranges, Nov., 1902, Dec. 1903, and 



Jan. 1905 (Robinson). 



It is closely related to Aecidium soleniiforme Berk., but until further 

 stages are found it will be retained as a distinct species. 



While the bright orange aecidia are very conspicuous and very plentiful 

 on both surfaces of the legumes, they are very rare upon leaves, having 

 hitherto only been found on the first or second pair of leaves of young 

 seedlings. 



The mycelium bearing the aecidia penetrated the fruit cover and entered 

 the seed, so that the young plant'is probably infected from the start.

I. Aecidia on brown orbicular spots, sometimes densely crowded, par- 

 ticularly when on fruit ; pseudoperidia cylindrical, elongated up to 

 J mm., white, radiately laciniate at margin. 



Aecidiospores rather angular, orange, 25-26 fi diam.

The aecidia, as the specific name denotes, are rather tubular at first.
