1. B. terrestris Kell. Scape very short, scarcely rising above the surface

 the slender pedicels 3 to 4 in. long; perianth purple, 8 to 10 lines long, the 

 limb rotate; anthers oblong, sagittate, \ x /-> lines long, slightly longer than 

 the filaments and shorter than the staminodia, these yellowish, emarginate and 

 with revolute edges. — (Hookera terrestris Greene.) 



Near the coast from Monterey ami Watsonville to Mendocino; common in 

 sandy soil in the region about San Francisco. June-July. 



2. B. minor Wats. Scapes slender, 3 to 6 in. high, bearing an umbel of 2 

 to 5 blue flowers on pedicels 1 to 2% in. long; perianth 8 to 12 lines long, its 

 tube oblong or even slightly inflated, the segments rotately spreading or often 

 strongly recurved, each with a mid-vein, green on back and running down 

 to base of perianth ; outer perianth-segments narrowed towards the apex, 

 mucronulate; inner segments broadly oblong, obtuse; anthers 2 lines long, sagit- 

 tate at base, deeply bifid at apex; staminodia broadly ligulate or with somewhat 

 involute margins, at apex commonly refuse and mucronulate, somewhat (often 

 much) exceeding the anthers. — (Hookera minor Ktze.) 



Dry and often gravelly soil of the plains and low hills of the Sacramento 

 and San Joaquin valleys and southward to Southern California. 



3. B. grandiflora Smith. Harvest Brodiaea. Scape stout, 7 to 18 in. 

 high; leaves 1 line broad, thick or somewhat terete, about equaling the scape; 

 umbels 3 to 11-flowered, pedicels unequal, 1 to 3 1 /-* in. long; perianth violet- 

 purple, 1*4 to 1% in. long; segments narrowly oblong, longer than the tube, 

 in age withering and becoming caudate; anthers 4 or 5 lines long, sagittate 

 at base, entire at apex or nearly so, exceeding or at least equaling the 

 oblong lanceolate mostly acute staminodia; capsule stipitate, the body about •"> 

 lines long. — (B. californica Lindl. Hookera coronaria Salisb.) 



The most common species in the Bay region, dowering in May ami early 

 .lime at the time of the hay harvest when the hills and fields are turning 

 brown. Also through the interior to the Sierra Nevada foothills. 



4. B. ida-maia (Wood) Greene. Fire-cracker Plant. Scape slender, 

 erect, 1 to 3 ft. high, bearing an umbel of 6 to 13 flowers with jointed pedicels 

 1 J _. in. long or less; leaves linear; perianth-tube scarlet, persistent, broadly 

 tubular, slightly 6-saccate at the truncate base, slightly constiicted above, 1 to 

 IVi in. Long; segments chrome-green, short, ereel or sometimes reflexed, 2 or :> 



lines long; stamens 3, inserted on the throat opposite the inner segments, 



their filaments very Bhort; anthers innate; staminodia .*!, vhito; capsule tri- 

 angular-ovate, acuminate, its stipe 2 or 3 lines long; seeds angular, black. — 

 (Brevoortia ida-maia Wood. Brodiaea coccinea Wats.) 



Wooded foothills and mountain slopes from Marin Co. to Mendocino and 

 Shasta COS. A showy and curious species.
