1921] LONG—RUSTS 41 
uredinia and telia collected on same host and in same locality June 25, 1920, 
by Long (no. 6891); also collected at Darling, Texas, on same host June 109, 
1920, by Long (no. 6892). 
The aecial stage of this Ravenelia is very conspicuous, while the other two 
stages are just the reverse. In fact, to find the uredinia and telia one must look 
on the leaves immediately adjacent to the aecial stage. At Darling, a flag 
station about 12 miles from Spofford Junction, the old witches’ brooms of this 
Ravenelia were very abundant for about 1 mile along the railroad track. Often 
some bushes would have from fifteen to twenty-five “brooms.” An occasional 
urediniospore was found intermixed with the telia in the Darling material. 
In the 1918 collection aecia and telia were found. The telia were very 
rare, only a few sori to each bush. In the 1920 material collected in the same 
catclaw-mesquit field, an abundance of both uredinia and telia were found 
associated directly with the old witches’ brooms. The uredinia were found 
on bushes growing in low damp spots with branches dense and close to the 
ground. On account of the abundance of the uredinia and telia in the 1920 
material this collection was made the type of these two stages. 
The uredinial stage of Ravenelia subtortuosae bears a close resemblance in all 
of its characters to the same stage of R. australis (as it occurs in Texas), even 
to the paraphyses, but differs materially in its telia from this species. R. sub- 
tortuosae is also related to R. MacOwaniana, found in south and central Africa 
on Acacia horrida, but differs from this species in many important characters. 
This is the only Ravenelia known to the writer reported from the Americas 
that has the three stages, aecia, uredinia, and telia. 
Ravenelia gooddingii, sp. nov. 
c. Pycnia unknown. 
II. Uredinia small, sparse (in material examined), I 
scattered, subcuticular, early naked, cinnamon brown; paraphyses 
very abundant, intermixed with the spores or in separate sori, 
subcylindrical to narrowly clavate, a few obovate, clavate type 
with thick walls and nearly solid heads, upper one-half to two- 
thirds of head fulvous, balance hyaline or nearly so, stipe solid, 
hyaline, 10-14 by 40-50 », obovate type thin-walled, subhyaline, 
with apex sometimes slightly thickened and fulvous, 1 5-18 X 
30-55 #; urediniospores broadly oval to globoid, 12-16X 16-109 », 
walls pale fulvous, thin, 1-1.5 , verruculose, pores 6-8, scattered. 
III. Telia amphigenous, but mainly hypophyllous, often 
Seated on pallid spots, usually found on basal half of the leaves, 
Very irregular, o.s—1.5 mm. X2-4 mm. long, often confluent over 
one-half to two-thirds ot the leaf, subcuticular, early naked, shining,
