314 LILIACE, 



lilies long, white, with purple veins. — Common on rooky banks and hills; 

 flowers vespertine, opening in the middle of the afternoon. June, July. 



7. SCOLIOPUS, Torr. Nearly stemless glabrous perennials, the 

 fascicle of coarse-fibrous roots bearing, on a short subterranean erect 

 stem, a pair of ample oblong leaves and the nearly obsolete peduncle of 

 an umbel, the elongated and sharply angled pedicels of which, resem- 

 bling 1-flowered scapes, alone appear above ground. Perianth of 3 

 ovate-lanceolate spreading sepals and as many linear erect petals. 

 Stamens 3, opposite the sepals; filaments short, cylindric, with a bulbous- 

 dilated base; anthers oblong, extrorse, attached above the base. Ovary 

 triquetrous; style very deeply 3- parted, the branches linear, stont, 

 widely spreading and with a downward curvature, stigmatic only at the 

 rounded apex, this held near the open anther by the curve in the style- 

 branch. Capsule thin, bursting irregularly. Seeds numerous, oblong, 

 slightly curved, sulcate-striate. 



1. S. Bigelovii, Torr. Leaves 4 — 15 in. long, mottled or without 

 dark spots, acute or obtusish: pedicels 3—15, slender, 3—8 in. long, 

 sharply 3 — 4-angled, in age reclining and strongly tortuous or somewhat 

 coiled: sepals spreading at base, bent downward abruptly from about 

 the middle, the ground-color green, but this obscured by many dark-red 

 strise: petals as long, strongly revoluteand nearly erect. — Mt. Tamalpais, 

 in low woods; flowers very fetid. Jan. — March. 



8. TRILLIUM, Miller. Perennials, with short fleshy rootstocks and 

 fibrous roots. Solitary erect stems scariously sheathed at base, at 

 summit bearing a whorl of 3 ample rhombic-ovate subsessile netted- 

 veined leaves and a solitary 6-merous flower. Sepals 3, lanceolate, 

 green-herbaceous, persistent. Petals 3, white or purplish to dark 

 maroon, exceeding the sepals, persistent. Stamens 6, on the base of the 

 perianth; filaments short, stout; anthers long, basifixed. Ovary sessile; 

 styles none; stigmas linear or subulate, recurved. Fruit an ovate 

 angular fleshy capsule 1 — 3-celled. Seeds ovate. 



1. T. sessile, L. Leaves and flower closely sessile; petals erect. Var. 

 gig-ante urn, Hook. & Arn. Stout, 1—2 ft. high: leaves broadly rhombic- 

 ovate, 3 — 6 in. long, usually broader than long, acutish : petals oblanceo- 

 late, 2— 4 in. long, dark-maroon to rose-purple and white. Var. chloro- 

 petalum, Torr. Still larger, the obovate-elliptic obtuse petals twice the 

 length of the sepals, and uniformly light green. — Only the varieties 

 occur; the first plentiful in the Oakland and Berkeley hills, the second 

 in the redwood districts of Marin Co. March, April. 



2. T. o vat n in, Pursh. Slender, 8 — 18 in. high: leaves 2—6 in. long,
