Fibrous-rooted biennial, 4.5-9.5 dm. high, the stem simple below the inflorescence, some- 

 what fistulose, striate; basal and lower stem-leaves numerous, linear or linear-lanceolate, 3.5-14 

 cm. long, 2-5.5 mm. wide (when emersed much reduced), attenuate at apex, acuminate at base, 

 thin and flat or if emersed thickish, 3-5-nerved; stem-leaves bracteiform, numerous, linear- 

 attenuate, 0.6-6 cm. long, 0.8-2 mm. wide, sessile by a rounded base, passing into the bracts 

 of the inflorescence; racemes numerous in a terminal cymose panicle, loosely flowered, capitate 

 becoming cylindric or ovoid-cylindric, 7-13 mm. thick, the axes 2-3.5 cm. long or less; bracts 

 lance-subulate or lance-ovate, ciliolate, spreading, persistent, 1.2-1.5 mm. long; pedicels 1-2 

 mm. long; flowers yellow, turning very dark-green in drying; sepals ovate-oval to lance-ovate, 

 obtusish to subacuminate, ciliolate, 1.2-1.8 mm. long; wings oval, 2.3-3 mm. long, 1.4-1.6 

 mm. wide, short-pointed at the slightly inflexed apex, scarcely narrowed at base, 3-nerved; 

 keel 2.5-2.7 mm. long, the crest of a lamella and 2-3 entire or bifid lobes; capsule depressed- 

 subhemispheric, 0.8-1 mm. long, 1.2-1.5 mm. wide; seed subhemispheric, dull, finely areolate, 

 glabrous, 0.8-0.9 mm. long; aril present but very minute, unlobed, 0.04 mm. long.

XIII. Monninopsis. Herbaceous or suffrutescent perennials, rarely annual; sepals free, 

 herbaceous, persistent; wings petaloid, persistent; keel with a fimbriate crest; upper cell of 

 capsule winged or margined, dehiscent, its seed arillate, the lower cell not winged or margined,

Stems slender, diffuse, filiform, flexuous, 2 dm. long, thinly puberulent, from a perennial 

 root; leaves lance-linear, 9-12 mm. long, 1-1.8 mm. wide, acute, apiculate, revolute, thin, 

 subspreading, scarcely crowded; racemes sinuate, becoming elongate, rather dense, scarcely 

 comose at apex, cylindric-pyramidal, 7-8 mm. thick, 1.5-2 cm. long; pedicels 0.6 mm. long; 

 flowers 3-3.5 mm. long; sepals ovate, the lower acute, less than half as long as flower; wings 

 subspatulate, shortly acute, gradually narrowed at base, 3-nerved; crest of a few rather broad 

 lobes; capsule strongly inequilateral, one cell broadly winged, the wing sinuate, veiny, the 

 other cell narrower, wingless, broadly rugose; seed curved, sparsely pilose; lobes of aril linear,
