ODONTOSOMA (Greek, toothed leaf, alluding to the 

 fact that the sori are on slender segms. of the leaf). 

 Polypodidcese. A group of tropical ferns formerly 

 included with Davallia; characterized by the decom- 

 pound Ivs. with cuneate ultimate segms. and the com- 



pressed suborbicular or cup-shaped indusium which is 

 attached at its sides and open only at the top. For 

 cult., see Fern. 



chinensis, J. Smith (Davallia chinensis, Smith. Steno- 

 loma tenuifolia, Fee). Lf. -blades 12-18 in. long, 6-9 

 in. wide, quadripinnatifid, on polished dark brown 

 stalks which rise from stout creeping fibrillose root- 

 stocks; ultimate divisions with toothed cuneate lobes; 

 sori terminal, usually solitary. Trop. Asia and Aus- 

 Polynesia. Var. stricta, Hort., has a more upright habit 

 and narrower Ivs. L M UNDERWOOD.

OECEOCLADES: Saccolabium. 



OENANTHE (name refers to the vinous scent of 

 the flowers). Umbelliferse. About 30 species of glabrous 

 often aquatic perennial herbs, rarely transferred 

 to grounds; some kinds are poisonous. They are 

 widely distributed about the world in temperate regions: 

 roots fibrous or tuberous: Ivs. 1-3-pinnate, much dis- 

 sected, sometimes reduced to a hollow or fistular petiole : 

 fls. white, small, in compound umbels, often polyga- 

 mous and the outer ones usually sterile and rayed; 

 calyx-teeth minute; petals 2-lobed or notched with an 

 inflexed point. CE. fistuldsa, Linn. WATER DROP- 

 WORT, native in Eu., W. Asia and N. Afr., is listed 

 abroad: roots of many fleshy fibers, running deep: st. 

 2-3 ft. high, stoloniferous, very hollow and thick, little 

 branched: radical Ivs. 2-pinnate, the lobed segms. 

 cuneate; st.-lvs. reduced mostly to hollow stalks, bear- 

 ing at the apex only a few linear-lobed segms. : umbels 

 terminal, each with 3-5 rays. Adapted to wet places, 

 for its ornamental and interesting character. 



L. H. B. 



(ENOCARPUS (wine fruit, as some of the species yield 

 a beverage). Palmacese. A few species of S. American 

 tall pinnatisect-lvd. palms differing from Euterpe in 

 character of calyx and infl. ; little grown, but numerous 

 in the Amazon and Oronoco countries. The Ivs. are 

 borne in a large crown, and the fls. are in spikes arising 

 beneath the Ivs. Some of the species yield useful oil: 

 fr. a medium-sized usually purple or black berry. 

 CE. Bacdba, Mart., and (E. Bataua, Mart., are the 

 species most likely to be mentioned. 



CENOTHERA (said to be Greek for wine-scenting; in 

 allusion to an ancient use of the roots). Onagracese. 

 EVENING PRIMROSE. Flower-garden and border plants, 

 prized for their showy bright yellow, rose or white 

 flowers. 



Herbs, or sometimes shrubby at the base, annual, 

 biennial and perennial, with alternate simple or pin- 

 natisect Ivs. and mostly showy fls., which are yellow, 

 white or rose-color: calyx with a tube prolonged beyond 

 the angled or cylindrical ovary, with 4 usually strongly 

 reflexed lobes; petals 4, mostly obovate or spatulate; 

 stamens 8, with narrow mostly versatile anthers: fr. a 

 4-valved loculicidal caps. The cenotheras are mostly 

 dry-soil plants and are chiefly N. American, the known 

 species being perhaps 90-100. Some of them are S. 

 American, and Bentham & Hooker admit 1 plant which 

 grows in Tasmania. The genus is polymorphous, and 

 there is consequently great difference of opinion as to 

 generic bounds. The marked differences reside in form 

 of caps., character of calyx-tube or hypanthium, and 

 in the habit of the plant. What is by some botanists 

 regarded as 1 genus is broken up into 10 or a dozen 

 genera by others. These genera are here treated 

 mostly as subgenera, for the group is fairly homoge- 

 neous from the horticultural point of view, and an 

 entirely new set of names in several strange genera could 

 scarcely be forced on the trade, particularly since the 

 botanists are themselves not in agreement. Godetia 

 is kept separate (Vol. III). Some of the true oenotheras 

 make glowing displays of yellow in the border; but the
