534 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



Corolla 2-lippod, rose-colored. 



Corolla 2 to 3 mm. long; spur 2 to 3 mm. hrn^i. 



Wings longer than the body of the fruit V. macroptera. 



Wings shorter than the body of the fruit. T^. macrocera. 



Corolla I. .5 mm. long; spur 1 mm. long F. ruheni^. 



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

 in Washington. 



2. Valerianella mamillata (Suksdorf). 



Aligera tiiamiUata Suksd.; Deutsch. Bot. Monatss. 4: 147. IS97. 

 Type locality: Simcoe Mountains, Washington. 

 Range: Known only from the type locality. 

 Specimens examined: Simcoe Mountains, SuJcsdorf. 



This species seems to us perfectly valid, the fruit appearing long-beaked partly owing to 

 the short wings. 



3. Valerianella congesta Lindl. Bot. Reg. 13: pi. lOD^. 1.827. 

 Plectritis congesta DC. Prod. 4: 631. 1830.

Betclcea major Fisch. & Mey. Ind. Sem. Hort. Petrop. II. 5: 30. 1837. 



Plectritis major Hoeck; Engl. Bot. Jahrb. 3: 37. 1882. 



Type locality: "Native of the north-west coast of North America." Collected by 

 Douglas in 1826. 



Range: British Columl)ia to California in the coast region. 



Specimens examined: Coupeville, Gardner 147; Admiralty Head, Piper, May, 1898; 

 Tacoma, Flett 55, 55; west Klickitat County, Sulsdorf, May, 1881; Bingen, Sheldon 10220; 

 Cape Horn, Piper 4984. 

 • Zonal distribution: Humid Transition. 



Three forms of this plant occur 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 l)ut the fruit. All three forms 

 occur in Washington. 



Plectritis congesta minor Hook. a has usually been 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.
