 A. Davidson, M.D. 



ALLIUM PSUEDOBULBIFERUM n. sp. 



Bulb 12 mm. in diameter, acutely ovate, smooth; the vertical 

 underground stem carrying the scaly remnants of 2 or 3 old bulbs 

 2 cm. apart;^ the active bulb terminal; stem 2 dm. high, terete; 

 leaves 2, linear above, 3 mm. wide at base; pedicels about 18 mm. 

 long; perianth white, the segments 6 mm. long, ovate, acute with 

 a green midrib, inner segments slightly smaller; stamens slightly 

 exserted; stigma 4 mm. long, undivided; ovary smooth, 3 lobed 

 Vv'ith a slight grooved depression on each lobe. 



No. 3410, type specimen, from elevated ground east of the 

 river at Victorv^ille. Collected by Robert Kessler, May 1, 1921. 



This has probably passed as A. serratum but is differs from 

 species in having the stamens exserted and it differs moreover 

 from all the other Alliums in this section in possessing a Calo- 

 chortus like bulb which is periodically renewed by the deeper 

 extension of the stem exactly as seen in Calochortus Plummerae. 



V ALLIUM KESSLERI n. sp. 



Bulb globular, 8 mm. in diameter the brown coating without 

 definite reticulation; stem solitary 10 cm. long, terete; leaf single, 

 linear, longer (sometimes twice the length of the stem) and 

 sheathing the base of the stem for one-fifth of its length; perianth 

 whitish fading to light lavender; pedicels about 10, 2 cm. long; 

 perianth segments lanceolate, 6 mm. long, the outer slightly 

 larger, whitish with light green midvein on the outer 3, this vein 

 indistinct or obsolete on the Inner segments; stamens widening 

 slightly to the base two-thirds the length of the perianth; style 

 4 mm. long with 3 linear stigmas; capsule with 6 small, rounded 

 crests topped with the remains of the cellular structures so con- 

 spicuous in anthesis. 



No. 3409, type specimen. Common on gravelly slopes on 

 Little Bear Creek, San Bernardino Mts., R. Kessler, June, 1920. 



In general appearance and habit this plant looks like a light 

 colored specimen of A. Parryi, but it is of a taller more erect habit, 

 the flowers are not so deeply colored, their segments are shorter 

 and are not retrocurved at the tip as are those of A. Parryi. The 

 stamens in A. Parryi are linear, and the capsules are erose on their 

 summits. 



/ ALLIUM MARVINII n. sp. 



Plant 2-3 dm. high; bulb oblong, tunicate, the outer coat 

 brown, rough, the inner white, smooth and glistening; leaves 5-6 

 all basal, one-half the length of the stem, somewhat fleshy, con- 

 cavo-convex and 5-8 mm. wide at base, semlterete at apex; stems 

 2 or more, slightly angular below, terete above; pedicles 12-20 or 

 more, 15 mm. long; perianth 5 mm. long, dull white with a brown
