Type Locality: Gasquets, Del Norte County, California. 



Specimens Examined: California. Del Norte County: Waldo-Crescent 

 City Road, Gasquets, April 23, 1907, A. Eastwood (No. 52, fr. submat.; Cal.; type!); 

 Rock Creek, April 29, 1907, .1. Eas/ (rood (No. 177, f.; Cal); Smith River near Adams, 

 May 4, 1907, A. Eastwood (No. 233, m. paratype; Cal.). 



At first, I was inclined to regard this plant as only a broad-leaved variety 

 of S. Breweri, but the shape of the gland in the male and female flowers is 

 different in the two. In S. Breweri the gland is narrower and often almost 

 filiform, especially in the female flowers in which it is half the length of the 

 young ovary. In S. dclnortensis the gland is also narrow but shorter and 

 never filiform. The anthers seem to be always yellow in S. Breweri and 

 violet in the new species, but, of course, a careful observation is needed of 

 more copious material with mature leaves and a study of the plants in the 

 field to fix the specific value of S. delnortensis . It apparently also grows in 

 a semiarid region; and Miss Eastwood collected another peculiar willow 

 near Gasquets, which too seems to represent a new species the relation of 

 which, however, is with 5. Scouleriana notwithstanding a certain similarity 

 to S. dclnortensis in its external appearance. I shall deal with it when I 

 speak of S. Scouleriana in a later note. 



THE BONIN ISLANDS AND THEIR LIGNEOUS VEGETATION 



E. H. Wilson 



Some 520 miles almost due south of Tokyo, Japan, is a group of small 

 islands known to the western world as the Bonin Islands and to the Japan- 

 ese as Ogasawara- shima. These islands are governed by the Tokyo prefect, 

 and communication is maintained by a monthly steamer plying from 

 Yokohama. They lie between the parallels of Lat. 27° 5 m. and 26° 30 m. N.,
