pedicels ascending, incurved, subtended by conspicuous, 

 scarious. ovate, acuminate bracts marked by three or more 

 reddish veins ; perianth 3cm. long, very slightly constricted 

 above the ovary, the tube greenish, a little over 1cm. long, seg- 

 ments oblong, violet, somewhat spreading, marked with a dark 

 midvein, the outer ones blunt, about 4mm. wide, the inner ones 

 acute, somewhat narrower ; staminodia erect, white, 2.5cm. 

 long, closely investing the stamens, and slightly exceeding 

 them. 



No. 5742, collected at the Petrified Forest, Sonoma county, 

 June 23, 1902, growing in dry, open gravelly ground. It 

 resembles H. coronaria outwardly, but m that species the 

 staminodia lie against the lobes of the perianth, and 

 consequently stand entirely away from the stamens. The 

 present species and Brodiaea Purdyi, Eastwood, Proc. Cal. 

 Acad. II. 6; 427, pi. 58 1896. are the only ones in the genus so 

 far noted which have the staminodia erect and closely investing 

 the stamens. The perianth of B. Purdyi is rotate, a point which 

 is hardly shown in either the description or the plate. It is 

 very abundant in the valleys among the foothills near Chico, 

 Butte county, the type locality, where it was collected by the 

 writer, under No. 5524. 



y TRITELEIA ANGUSTIFLORA sp. nov. 



Scape erect from a deep-seated, heavily coated fibrous 

 corm. about 3dm. high, but occasionally much taller; involucral 

 bracts lance-acuminate. 1-1. 5cm. long, veined; umbel 5-15 

 X flowered, pedicels 1.5cm. long: perianth deep indigo-blue, about 

 2.5cm. long, narrow funnelform, slightly unequal below, the 

 segments about 1cm. long, the outer ones narrower than the 

 inner, acute ; the inner obvate-spatulate, obtuse : anthers 

 versatile but- erect, unequally inserted, those opposite the outer 

 segments an anther-length shorter than the others. 



No. 5728, collected on Tiburon peninsula along the Bay 

 road, Marin county, June 19. 1902. 



Technically there is little to distinguish this species from 

 T. laxa, but in the field it is evidently distinct. It. begins to 

 bloom at least a month later, has a smaller, less fiaring flower, 

 of a rich, deep indigo-blue, and is more confined to wooded 

 banks and slopes. It was first noted on the slopes of Tamalpais 

 above Mill Valley, and is plentiful throughout Sonoma county 

 in favorable situations.
