scarcely clustered, with ascending branches at or after flower- 
ing; leaves as much as 7x20 em., little crenulate, broadly 
lanceolate to ovate lanceolate, acute, mostly rounded at 
base ; inflorescence with several or in large plants numerous 
rather divergent branches, at length congested; whorls 
dense, approximate; pedicels rather slender, about as long

white, wrinkled and pitted, 1 mm. wide and two-thirds as

Rich soil, especially near brooks, etc., Massachusetts and 
New York to Dakota, south to the District of Col- 
umbia, Nebraska, and Texas. —Specimens examined 
~ from Nahant, Mass. (Oakes, as R. pallidus, Bigelow), 
western New York ( Clinton, 1864), Pennsylvania ( Porter, 
- 1857; Garber, 1868), Maryland (Sm2th, 1881), District of 
Columbia ( Ward, 1876, 1879; Mohr, 1882), West Vir- 
ginia (Mertz, 1877 and 1878), Ohio (Prank, 1835; Lea; 
James), Indiana (ex hb. Wood.), Illinois, Wisconsin, 
Dakota (Geyer, 1839, 143; Hayden, 1853; Glatfelter, 
1865, 376 in part), Nebraska ( Webber, 1886 ; Holms, 1889), 
Kentucky, Missouri, Iowa, Indian Territory, ( Butler, 1877, 
6), and Texas? (Leverchon, 1876; Tweedy, 1880; Jermy, 
149). According to memoranda on a St. Louis specimen 
in the Meisner herbarium, Meisner regards this as the same 
as LR. Claytonii, Campdera; but there is too much doubt 
concerning this point for me to displace the now established 
name given by Wood.— Plate 25.
