1. M. niaritima (Benth), Wats. Oorm depressed, % — % in. thick, 

 fibrous-coated: leaves many, 4 — 8 in. long, scabrous-margined: scape 

 hardly longer than the leaves, erect, straight: pedicels 5 — 15: perianth- 

 segments 2—2% lines long, the sepaline oblong, slightly revolute, the 

 petaline oval, plane: capsule }£ in. long, abruptly beaked by the stout 

 style: seeds black, oblong, compressed and angular. — Borders of' salt 

 marshes about the Bay, and in subsaline soils of the interior; but also 

 on the highest parts of the Mission Hills, in dry stony soil. March, April. 



21. ALLIUM, Pliny. Scapes and leaves from a tunicated bulb, or 

 rarely from a coated corm: the whole plant always with alliaceous odor 

 and flower. Umbel with a 2-valved (rarely 3— 5-valved) spa the; pedicels 

 not jointed. Perianth of 6 distinct or nearly distinct, usually equal 

 segments, often gibbous at base. Stamens 6, on the base of the seg- 

 ments; filaments often dilated below; anthers versatile. Ovary sessile, 

 deeply 3-lobed, with very short axis. Capsule obtusely 3-lobed, obovate- 

 globose, often crested. Seeds obovoid, wrinkled, black. 



* Scape flattened, S-edged, and leaves 2, from a coaled bulb. 



1. A. falcifolium, Hook. & Am. Leaves 2, broadly linear, flat, fal- 

 cate, 3—4 lines wide: bulb-coats with no reticulation: scape 2 — 3 in. 

 high, 1 — 2 lines wide: fl. rose-colored, the segments lanceolate, attenuate 

 and spreading at the tips, glandular-serrulate, 4—6 lines long; stamens 

 and style little more than half as long. — Inner coast hills, from Solano 

 and Sonoma counties northward. April. 



2. A. Breweri, Wats. Bather smaller, but bulbs larger (% — % in. 

 thick): scape 1 — 2 in. above ground: 2 leaves rather broader: segments 

 of deep rose-colored perianth nearly erect, 5 — 6 lines long, only a third 

 longer than the stamens: ovary and capsule with a thick crest on each 

 cell.— Summit of Mt. Diablo. 



* * Scape terete, leaves several, from a coaled bulb. 



3. A. lacunosnm, Wats. Bulb-coats pale, pitted by a transversely 

 oblong or somewhat quadrate reticulation, the outline of the cells very 

 minutely sinuous: scape 3 — 6 in. high: fl. 5 — 20 on pedicels 3—5 lines 

 long, the oblong-lanceolate acuminate segments 3— 4 lines long, little 

 exceeding the stamens: filaments narrowly deltoid at base: ovary-cells 

 with an obtuse ridge toward the summit on each side. — Summits of the 

 higher mountains from Mt. Diablo southward. June. 



4. A. serratum, Wats. Bulb-coats with u, close horizontally serrate 

 reticulation: perianth deep rose-purple, 5 lines long; sepaline segments
