On September 14, 1910, the writer again visited Deadwood 
for a short time and studied the willows found on the northern 
flank of the White Rocks, principally around a spring lying just 
below the wagon road. Here S. Bebbiana and S. prinoides were 
found abundantly and S. lutea less commonly on the seepy slope 
below the spring. Two or three stunted plants of S. Scouleriana 
occurred in dry ground just across the road above the spring. 
On August 23, 1913, the writer collected S. Jutea at the railroad 
station at Mystic, and S. Bebbiana and S: Scouleriana again at the 
spring north of the White Rocks at Deadwood. All these collec- 
tions are cited under the respective species at the end of this article.” 
In the spring and summer of 1910, Mr. Jonn Murpocu, JR., 
of the United States Forest Service, collected an extensive series 
of specimens in various parts of the Black Hills. A portion of 
the series was sent to the writer for identification through the 
United States Forest Service, on April 1, 1913. Seventeen num- 
bers were flowering specimens of S. prinoides and S. Bebbiana, one 
was S. fluviatilis, and one proved to be a young pistillate specimen 
of S. Nelsonii Ball, a rather rare member of § PHYLICIFOLIAE, 
known previously from the mountains of Colorado and Wyoming. 
A more complete set from the private herbarium of the collector 
was submitted to the writer by Dr. Geo. B. Supworts, dendrol- 
ogist of the Forest Service, on January 14, 1915. It was found 
to contain, besides numerous specimens of S. prinoides and S. 
Bebbiana, the specimen of S. Nelsonii (no. 4039) mentioned above, 
collected at Redfern Plantation no. 2, and also a specimen bearing 
mature foliage (no. 4233), collected at the same place in July. 
% Since this paper was prepared, the writer has seen a series of short papers by 
VisHer, entitled Additions to the flora of the Black Hills of South Dakota (Torreya 
9:186-188. 1909; Muhlenbergia 8:135-137. 1913; ibid. 9:33-39- 1913)- In the 
first paper he records S. Scouleriana as “Frequent, forming trees, in deep woods, well 
up on Custer’s Peak.’”’ The collection was made in August 1908, just a month 
before it was collected by the writer at Deadwood. 
ne of another series of papers (Additions to the flora of South Dakota. 
II. Muhlenbergia 9:69-77. 1913) ViSHER reports S. Fendleriana as ‘‘Common m 
boggy soil in the forest reserves and along the Little Missouri River” of Harding 
County, north of the Black Hills, in the northwest corner of the state.
