 nate at the apex, narrowed into slender petioles, 

 irregularly sinuate-dentate with acute teeth, 1'-$' 

 long or the upper much smaller; spikes numerous 

 in terminal panicles, loosely flowered, 1'-$' long, 

 slender; fruit, including the winged calyx, 2" broad;

5. MONOLEPIS Schrad. Ind. Sem. Gott. 4 T 1830. 



Low annual branching herbs, with small narrow alternate entire toothed or lobed leaves, 

 and polygamous or perfect flowers in small axillary clusters. Calyx of a single persistent 

 herbaceous sepal. Stamen i. Styles 2, slender. Utricle flat, the pericarp adherent to the 

 smooth vertical seed. Embryo a very nearly complete ring in the mealy endosperm, its 

 radicle turned downward. [Greek, single-scale, from the solitary sepal.]

Slightly mealy when young, pale green, glabrous 

 or nearly so when old; stem 3'-! 2' high; branches 

 many, ascending. Leaves lanceolate in outline, 

 short-petioled, or the upper sessile, #'-2#' long, 

 narrowed at the base, 3-lobed, the middle lobe lin- 

 ear or linear-oblong, acute or acuminate, 2-4 times 

 as long as the ascending lateral ones; flowers clus-

 green, in panicled spikes or capitate-clustered in the axils. Staminate flowers bractless, con- 

 sisting of a 3~5-parted calyx and an equal number of stamens; filaments separate or united 

 by their bases; a rudimentary ovary sometimes present. Pistillate flowers subtended by 2 

 bractlets which enlarge in fruit and are more or less united, sometimes quite to their summits, 

 their margins entire or toothed, their sides smooth, crested, tubercled or winged; perianth 

 none; ovary globose or ovoid; stigmas 2. Utricle completely or partially enclosed by the 

 fruiting bractlets. Seed vertical or rarely horizontal; embryo annular, the radicle pointing 

 upward or downward; endosperm mealy. [From a Greek name of orache.] 



About 130 species, of very wide geographic distribution. Besides the following, some 45 other* 

 occur in the western parts of North America. 

 Annual herbs; stems or branches erect, diffuse or ascending. 



Leaves hastate, ovate, rhombic-lanceolate or linear-lanceolate. 



Plants green, glabrous or sparingly scurfy, not silvery; leaves slender- petioled. 



Leaves lanceolate, several times longer than wide. \ . patttla. 



Leaves triangular-hastate, the lower only 1-2 times as long as wide. 2. A. haslata.
