DI.iDELPUIA. OCTANDRIA. 89 



tes deciduous; stem erect and brnnched. Hab. Common 

 tlirouL^liout 'lie Atlantic states. 



14. * ambig^iia. Annual: first leaves verticillate, line- 

 ar, the rest aiiernate; stem vlrgately branched; spikes 

 acute, upon very long- peduncles; flowers cristate, pur- 

 plish; calicine wing's round and venose, equal v.jili the 

 fruit to wliich they are appressed; bracics dec;duous. 

 Hab. In New Jersey and Virginia; in forests and on load 

 sides near ditches, abundant, but not so common as the 

 preced.ng, to which it very nearly approaches. After seve- 

 ral years examination in a living' state I am decidedly in- 

 duced to consider it a separate species; the J^owtrs are 

 larger, purple, and distinctly pedicellate; 1 have now be- 

 fore me specimens in which the filiform spike and its pe- 

 duncle is from 6 to 8 inches long-. The flowers of both 

 these species are distinctly cristate. 



15. * fastig-iata. Annual: stem slender and fastigiately 

 branched; leaves alternate, linear, acute; sj/ikes subcapi- 

 tate, pedunculate; flowers subcristate; calicine wings 

 .spreading, ovate, acute, scarcely longer than the caps.ie. 

 II A3. In New Jersey, &.c. v. v. Nearly allied to cntciata, 

 more remotely to setacea, with which it is confounded in 

 Muhlenberg's Herbarium, v. s. 



16. cntciata. .Annual: stem fastigiately branched, an- 

 gular, angles alated; leaves linear-oblong, punctate, ver- 

 ticillate in 4's; spikes condensed, sessile; flowers subcris- 

 tate, calicine wings deltoidly -cordate, acuminate, con- 

 cealing the small and reflected capsule. Hab. On the 

 m.irgins of dry sphagnose morasses; not very common; 

 generally dwartiind spreading, spikes trom 10 to 15 lines 

 long, bractes persistent, calicine wings flatly spreading", 

 greenish, with a bright rosaceous margin, capsule minute, 

 substipitate. 



17. * bvevifoUn. Annual: stem erect, subfastigiately 

 branched, angular, angles alated; leaves oblong-hnear, 

 short, resinously punctate, verticillated in 4's; spikes pe- 

 dunculate, partly capitate; flowers subcristate; calicine 

 wings cordate-ovate, acute, scarcely longer than ihe cap- 

 sule. Hab. On the margins of sandy swamps, New Jer- 

 sey, also in Ohio. Flowering in July and August; some- 

 what rare. Obs, Nearly allied to the preceding, with 

 Avhich it has probably been confounded, though perfectly 

 distinct; it is more slemler, leaves scarcely half the size, 

 branches subvirgate and eiect, flowers brightish red. 



t Flowers coi^mbose. 

 IS. corymbosa. Fex'ennial: stem simple, angular, summit 

 corymbose, many-flowered; radical leaves spaihulate-obo- 

 vate, cauline subequal, Imear; ctdicine wings conniventj
