lip oblong, the dilated summit spreading and undulate, usually entire. 

 Column short, oblique, ending in a stout terete stipe bearing the ovate 

 stigma on the face. 



1. 0. Romanzoftiannm (Cham). Stout, 4—18 in. high, bracteate 

 above: leaves oblong-lanceolate to linear: spike dense, 3-ranked, 1 — 4 

 in. long, conspicuously bracteate: perianth white, about 4 lines long; 

 sepals and petals all connivent; lip recurved, ovate-oblong, contracted 

 below the wavy-crenulate summit; callosities obscure. — Near the Presidio, 

 San Francisco, Bolander, and in Marin Co. Sept. 



2. 0. porrifolium (Lindl.). Much like the last, but with smaller 

 flowers, and consequently a narrower spike: callosities al base of lip 

 sharply prominent and pointing downward. — Marin Co., Behr. 



3. HAUEXAKIA, Willd. Stems leaf y-bracted or leafy, erect simple 

 and solitary, from perpendicular fleshy-fibrous or tuberiform roots. 

 Flowers small, green or white, in a terminal spike or raceme. Sepals 

 and petals similar, convergent: lip flat, spreading entire (in ours), with a 

 slender long spur at base on the outside. 



1. H. elegans (Lindl.), Bolander. Stem rather slender, 1 — 2 ft. high, 

 from an ovate or oblong tuberform root: leaves 2, radical, depressed, 

 oblong, 3 — 5 in. long and 1^—2 in. broad, appearing in early spring, but 

 dying and disappearing before the flowering period: fl. small, light green, 

 in a slender but dense long spike; sepals and petals subequal, 2 lines long, 

 obtuse; lip similar, with filiform spur 3 — 5 lines long: beak of stigma 

 prominent, broad and rounded. — Wooded hillsides. June, July. 



2. H. maritima, Greene. Kobust, 6 — 16 in. high; at flowering time 

 destitute of foliage, but the upper part of the stem bearing many lanceo-

 long or more: spike 1}4 — 3 * ra - long, 1 in. thick, the flowers closely 

 crowded, white, heavily honey-scented: sepals oblong, obtuse, 1% lines 

 long, white, with a narrow and delicate deep green midvein; petals not 

 quite equalling the sepals, oblong-lanceolate, the upper 2 plane, deep 

 green al base and well up the middle, otherwise while; the lip pure while even 

 to the prominently elevated and broad midvein: spur slender, longer than 

 the ovary. — On dry hills near the sea at Point Lobos; leaves probably 

 appearing in early spring and soon dying. Fl. Aug. — Oct. 



3. H. Michaeli, Greene. Very robust, 8 — 12 in. high, leafless, but the
