534 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



Corolla 2-lipped, rose-colored. 



Corolla 2 to 3 mm. long; spur 2 to 3 mm. long. 



Wings longer than the body of the fruit V. macroj>tera. 



Wings shorter than the body of the fruit V. macrocera. 



Corolla 1.5 mm. long; spur 1 mm. long V. rubens. 



True macrocera on this basis is confined to California. The remaining segregates occur 

 ■ in Wjishington. 



2. Valerianella mamillata (Suksdorf). 



Aligera mamiUata Suk.sd.: Deutsch. Bt>t. Monatss. 4: 147. 1897. 

 Type ixk'Akity: Siinco<» Mountains, Washington. 

 Range: Known only from the type hxality. 

 Specimens examined: Simcoe Mountains, Suhidorf. 



This s|)ecies seems t<> us perfectly valid, the fruit appearing long-l)cakod partly owing to 

 the short wings.

Type iX)CALiTi': "Native of the north-west coast of North America." Collected by

Three forms of this plant <K'cur as to fruit, one wingless (major), the .second narrowly 

 winged {microptera), the third broadly winged {congesta). They are considered distinct 

 species by Suksdorf, but they do not differ in any character but the fruit. All three forms 

 occur in Washington. 



Pledritis congesta minor Hook.« has usually Ixwn considered a synonym of V. macrocera, 

 but its type locality "near the mouth of the Columbia" is a region where macrocera is not 

 known to occur.
