vicinity of San Francisco or at Monterey. A good cut 

 accompanies the description. 



C. lilacimis was first described by Kellogg from specimens 

 collected near Calistoga, Napa County, California. Dr. 

 Kellogg's original description, together with a water color 

 drawing, are in the Herbarium of the California Academy 

 of Sciences. 



After carefully comparing all the data contained in the 

 descriptions of C. unijioriis and C. lilacinus with both fresh 

 and herbarium specimens from Monterey, Calistoga, and a 

 number of other localities, the writer is thoroughly convinced 

 that the two species are the same. The description of C. 

 tmijiorus was published much earlier than that of C. lila- 

 cinus; it is drawn from a fair specimen of the species. 



It is obvious that Dr. Watson confused C. lilacinus with 

 the quite different C . umbellatus. 



The writer has seen C. u7iijlorus in meadows high in the 

 mountains where the plants grew very low and slender and 

 were only one- to three-flowered. In rich ground several 

 bulblets are produced annually, and if left undisturbed large 

 and dense masses are formed, sometimes hundreds of them 

 to the square foot. In soft ground the stems are apt to run 

 along close to the surface a few inches to a foot before 

 coming through, and in these situations plants a foot high 

 with pedicels ten inches long are not uncommon. 



^ 13. Calochortus shastensis, sp. nov. 



Scape low, slender, 4 to 10 inches high, but unusually erect, with a single 

 shining light green radical leaf 3 to 6 inches long, of almost uniform width 

 (3 to 6 lines), but abruptly acute at apex; bracts lanceolate, 6 lines long; 

 sepals long, ovate, acute and acuminate, greenish without, lighter within, 

 purple spotted near base; petals white or lilac, broadly fan-shaped, somewhat 

 truncated above, denticulate, naked except that some few specimens have a 

 few hairs above the narrow, fringed, ascending scale which divides the gland; 

 anthers linear, obtuse, slightly sagittate; capsule as in preceding but erect. 



Found in open moist meadows in the vicinity of Sissons, 

 California, at the base of Mt. Shasta, and about springy 

 places on the western flank of the mountain. 



C. shastensis has long been known and collected as C. 

 nudtcs, which it closely resembles in flower but from which
