269, 1900, with leaves more like V. urticaefoUa; Tracy, 

 South Pass, La., no. 22, 1900. Specimens are also common 

 in West Indian collections. A specimen collected by Ball at 

 Alexandria, La., no. 556, is a good example of V. urticae- 

 foUa from the Southern States. 



SiLPHIUM INTEGRIFOLIUM Michx. 



Two rather distinct forms have been placed under this^ 

 name in the Middle West, besides the many variations from 

 Texas found in herbaria, most of which could probably be 

 placed more properly with some of the Texan species now 

 recognized. One form is a large plant with glabrous and 

 glaucous stem or with a few hairs on the upper part, and 

 large glabrous or scabrous leaves. This is well represented 

 by many collections from Central Kansas. It is possible that 

 this is the variety la&ve of Torrey and Gray, and if so should 

 stand as a good variety under that name if not as a species. 

 The other form is smaller with smaller leaves, and has the 

 stem and leaves covered with a short, dense, staring pubes- 

 cence, which appears quite different from the longer scat- 

 tering appressed hairs found on other forms. This occurs 

 eastward and is well represented by the following specimens : 

 Hitchcock, Olathe, Kan., 1892 ; Fink, Fayette Co., Iowa, no. 

 535, 1894; Wolf, Center, 111., no. 28, 1881. 



Brauneria paradoxa n. sp. 



Stem glabrous or slightly scabrous or hispid, 3 to 8 dm. 

 high ; lower leaves narrowly lanceolate, 12 to 25 mm. wide, 

 about 2 to 3 dm. long including the petiole which is some- 

 times 15 cm. long, glabrous or nearly so, entire; the 3 to 5 

 distinct nerves yellow, translucent; upper leaves smaller and 

 wider in proportion, nearly sessile ; peduncle 2 to 3 dm. long, 

 comparatively slender, striated, somewhat pubescent at the 

 apex ; heads 2.5 cm. wide, 3 cm. high, dark brown ; rays 

 bright yellow, drooping or spreading, 4 to 6 cm. long. Com- 

 mon in prairie and barrens in Southwest Missouri. — Plate

The type is from Swan, Mo., collected by B. F. Bush,
