Some new Species from Washington 



Ey K, M. Wieganh 



(Plate 355) 



The several sets of Washington plants collected by Mr. J. B. 

 Flett afford the following apparently undescribcd species. Two of 

 these are from the vicinity of Tacoma and arc already represented 

 in the larger herbaria under other names. Those from the Olym- 

 pic Mountains I have never seen from elsewhere. 



Allium crenulatum 



Very low and dwarf (4-5 cm. high), from a small globose bulb, 

 the latter not fibrillar : scape 2-edgcd (1.25 mm. wide), edges crenu- 

 latcly roughened : leaves 3-4 cm. long, narrow (1.5 mm. wide), re- 

 curved, edges crenulate: umbel few-flowered : bracts two, large, scari- 

 ous, ovatc-oblong, acute (8-10 mm. long) : pedicels shorter than the 

 flowers : perianth pink, segments (8 mm. long) lanceolate, acutish : 

 stamens one-half the length of the perianth : anthers short-oblong : 

 filaments naked : ovary six-crested at the summit but not horned : 

 style I mm. long. [Plate 355.]

ph 



angles to the scape, and has fewer flowers ; the leaves are also 



much narrower. 



Lathyrus Torreyi tenellus var. nov 



Vei 



decumbent at the base 



(10-25 cm. high) from a very slender rootstock, short-hirsute 

 with crisp white hairs intermixed with a few sessile glands : 

 leaves (4-5 cm. long) oblong: leaflets 5-7 pairs, small, thin, 

 elliptical, acute at each end, mucronately pointed, light green 

 (12-16 mm. long), sparingly hairy on both surfaces; pulvinus 

 strongly hirsute ; stipules (8 mm. long) semi-ovate-lanceolate, 

 acuminate and hastate, the lower lobe acute; rachis scarcely 

 prolonged beyond the upper leaflet: flowers (i 5-1; mm. long) 

 1-3 (mostly 2) on a slender hirsute peduncle 1-6 cm. long; pedi-
