Froelichia gracilis Moq. in DC. Prodr. 13'; 420. 1849. 



Similar to the preceding species but the stem slender, 

 branched, especially from the base, or sometimes simple, 

 io'-2o' tall. Leaves all linear or linear-oblong, acute 

 at both ends, 9"-2' long, sessile or the lower commonly 

 spatulate, obtusish and narrowed into very short peti- 

 oles; spikes alternate or opposite, oblong, mostly obtuse, 

 i'-i' long; fruiting calyx with 5 longitudinal rows of 

 processes or these confluent into interrupted crests. 



In dry soil, western Missouri and Nebraska to Colorado 

 and Texas. June-Sept. 



Gomphrena globosa L., the Globe Amaranth, cultivated 

 for ornament, native of the Old World tropics, with densely 

 capitate red or white flowers, the filaments united into a 

 long tube, has been found in waste grounds in Ohio. 



5. IRESINE P. Br. Civ. & Nat. Hist. Jam. 358. 1756. 



Annual or perennial tall herbs, with opposite broad petioled thin leaves and very small 

 polygamous perfect or dioecious 3-bracted white flowers, in large terminal panicles or pan- 

 icled spikes. Calyx S-parted, the pistillate usually woolly-pubescent. Stamens 5, rarely less ; 

 filaments united by their bases, filiform ; anthers l-celled. Utricle very small, subglobose, 

 indehiscent. [Greek, in allusion to the woolly pubescence.] 



About 20 species, natives of warm and temperate regions. Besides the following typical species 

 another occurs in the southwestern United States.

Family 17. CHENOPODIACEAE Dumort. Anal. Fam. 15. 1829. 



GoosEFOOT Family. 



Annual or perennial herbs, rarely shrubs, with angled striate or terete stems. 

 Leaves alternate or sometimes opposite, exstipulate, simple, entire, toothed or 

 lobed, mostly petioled (in Salicornia reduced to mere ridges). Flowers perfect, 

 pistillate, polygamous, monoecious or dioecious, small, green or greenish, regular, 

 or slightly irregular, variously clustered, commonly in panicled spikes, bractless 

 or bracteolate, occasionally solitary in the axils. Petals none. Calyx persistent, 

 2-5-lobed, 2-5-parted or rarely reduced to a single sepal, wanting in the pistillate 

 flowers of some genera. Stamens as many as the lobes or divisions of the calyx, 

 or fewer, and opposite thein ; filaments slender ; anthers 2-celled, longitudinally 

 dehiscent. Disk usually none. Ovary mostly superior and free from the calyx, 

 i-celled; ovule solitary, amphitropous ; styles 1-3; stigmas capitate, or 2-3-lobed
