bulbs." This is apparently the only Quamasia he collected, and as it 

 came from identically the locality where Mr. Cusick now finds this white- 

 flowered plant so abundantly, there can be but little doubt that the type 

 locality of Quamasia leichllinii is not British Columbia as published, but 

 the Umpqua Valley of Oregon. 



In the vicinity of Roseburg, Mr. Cusick also collected plants with dark 

 blue flowers and others with pale blue flowers. These appear to differ 

 from typical Q. leichtlinii in no other respect than the color of the corolla. 

 White-flowered mutants in blue-flowered plants are very common and 

 have been reported in other species of Quamasia. It is noteworthy, how- 

 ever, that in the many specimens of Quamasia leichtlinii in the National 

 Herbarium, only one, namely, that collected by Howell at Oakland, also 

 in the Umpqua Valley, has white or whitish flowers. 



Mr. Cusick' s abundant and complete material of Quamasia leichtlinii 

 permits of a critical comparison with the blue-flowered plants that have 

 been described under the names Quamasia azurea Heller and Camassia 

 suksdorfii Greenman. 



Both of these plants agree with Q. leichtlinii in having the perianth 

 segments spreading regularly and after anthesis becoming connivent and 

 twisting together, whereas in other species of Quamasia the segments 

 remain separate. 



Quamasia suksdorfii (Greenman) Piper. {Camassia suksdorfii Green- 

 man, Bot. Gaz. 34:307. 1902; Quamasia suksdorfii Piper, Cont. Nat. 

 Herb. 11 : 191. 1906) is based on specimens collected by Suksdorf in 

 Klickitat County, Washington. Doctor Greenman in proposing the 

 species comments as follows : ' ' From Camassia leichtlinii Watson * * * 

 C. suksdorfii diflers in the color of the flowers, the less sharply triangular, 

 thinner, and less conspicuously nerved capsule. The seeds, moreover, in 

 C. suksdorfii are larger and have a more bluish luster than in C. 

 leichtlinii." 



Incidentally it may be added Dr. Watson's conception of Camassia 

 leichtlinii (Proc. Am. Acad. 20 : 376) was based largely on Suksdorf's 

 material and notes of the plant named C. suksdorfii by Dr. Greenman. 



Quamasia azurea Heller, Bull. Torr. Bot. Club, 26 : 547. 1899, is based 

 on specimens collected near Montesano, Washington. It is compared 

 with Q. quamash from which it is said to difl'er in its more delicate bright 

 blue flowers, and by growing on grassy slopes. The type has not been 

 examined but other material from near the type locality answer its de- 

 scription accurately. 



Q. leichtlinii as represented in Mr. Cusick' s specimens has a cream - 

 colored perianth segment 20-30 mm. long, all either 5-nerved or 7-nerved. 



Q. suksdorfii has blue perianth segments all 7-nerved, the two outer 

 nerves short. The capsules of the two show no characteristic diflFerence. 

 The value of the seed characters is difficult to judge as so few of the 

 specimens possess mature fruit that can confidently be associated with 

 specimens in bloom. In all the Pacific Coast species they are very much 

 alike. Those in Mr. Cusick' s specimens of Q. leichtlinii are decidedly
