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. Romaiizoftianum (Cham.). Stout, 418 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. porrifolinm (Lindl.). Much like the last, but with smaller 

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

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



3. HABENARIA, Willd. Stems leafy-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, 12 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. inaritima, Greene. Eobust, 616 in. high; at flowering time 

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

 late-subulate appressed and more or less imbricated green bracts % in. 

 long or more: spike 1% 3 in. 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 at base and well up the middle, otherwise white; the lip pure white 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, 812 in. high, leafless, but the 

 cyllndric and apparently very fleshy stem bearing many triangular or tri- 

 angular-ovate acuminate thin appressed bracts: spike very dense, 3 in. 

 long: fl. greenish; sepals and petals alike, % in. long; lip broader, its 

 spur a third longer than the ovary. Open hills, under oaks, etc., from 

 near Livermore southward.

 solitary scapes from fleshy short jointed often coralline roots, and bearing
