abruptly contracted into a stout stipe 1.5-2 mm. long, the faces wrinkled. — Differs 

 from Gaura simulans in the glabrous, at least ultimately glabrous foliage, and the 

 larger and longer-stipitate fruit-bodies. 



On sandy beaches, Punta Rassa, Florida. Spring. . 



Page 850, after Proserpinaca 'pectinata insert: 



la. Proserpinaca intermedia Mackenzie. Stems decumbent and creeping, 

 simple or sparingly branched. 1-3 dm. tall: leaves of 2 kinds; blades of the sub- 

 merged ones pectinate-pinnatifid, divided to the rachis; blades of the emersed ones 

 oblong varying to broadest above or below the middle, pectinate: flowers sessile in 

 the axils of the emersed leaves: sepals triangular, acute: fruit ovoid, above 4 mm. 

 long, sharp-angled, the flat or slightly concave faces rugose or wrinkled. — Differs 

 from P. palustris in the pectinate emersed leaves and from P. pectinata in bearing 

 two kinds of leaves. 



In pine lands, New Jersey and Georgia. Spring to fall. 



3. Proserpinaca platycdrpa Small. Stem and branches 1-3.5 cm. long, very 

 leafy: leaves uniform or the lower ones with more prominently toothed blades than 

 the upper; blades oblong or elliptic, or slightly broadened upward, 1.5-5.5 em. long, 

 sharply serrate: sepals deltoid or ovate-deltoid, barely 1 mm. long: hypanthium 

 ridge-winged: fruits 4-5 mm. wide, constricted above the middle, the angles thus 

 abruptly dilated. — Differs from P. palustris in the fruits which are abruptly con- 

 tracted below the apex. 



In pools and pot-holes, southern peninsular Florida. Also in the Bahamas. AH year.

Page 862, after Eryngium prostratum, insert: 



2a. "■ Eryngium dlvaric^tum H. & A. Plants similar to those of Eryngium 

 Baldwinii and E. prostratum in habit, but stouter. Stem and branches striate: leaves 

 firm; blades various, those of the lower leaves bipinnatifid, those of the upper ones 

 pinnatifid, the segments linear to lanceolate, minutely spine-tipped: heads ovoid, 

 becoming oblong, 1 cm. long or less: bracts of the involucre linear-subulate, spread- 

 ing: fruits less than 1 mm. long, bristly. — Differs from E. prostratum in the stout 

 habit, the bipinnatifid basal leaves and the bristly fruits. 



In low grounds, about seaports. North Carolina and Florida. Naturalized from 

 Argentina. All year. 



Page 864, after ChaeropJiyllum Teinturieri, insert: 



6a. ANTHRISCUS Bernli. 

 Annual herbs, resembling Chaerophyllum. Leaf-blades ternately decompound, 

 the segments small. Umbels compound, regular or nearly so. Involucre of toothed 

 or compound bracts. Involucels of narrow mostly entire bracts. Sepals obsolete. 

 Petals white, usually nearly or quite equal, inflexed at the apex. Carpels elongate, 

 the bodies more or less angled, but not ribbed: oil-tubes wanting. — Differs from 

 Chaerophyllum in the long-beaked ribless fruits. 



1. Anthriscus Cerefbllum (L.) Hoffm. Plants 1 m. tall or less, often weak- 

 stemmed: leaf -blades broad, the segments rather numerous, thin: umbels long- 

 peduncled, the rays few, 2-4 mm. long: petals white, obovate, 1.5-2 mm. long: fruits 

 linear-subulate, 8-10 mm. long, slender-beaked. 



In waste places and on roadsides, Quebec to Pennsylvania and Louisiana. Naturalized 

 from Europe. Spring. Chekvil. 



Page 866, after Museniopsis Texana, insert: 



13a. CONIUM L. 



Biennial large herbs with spotted stems. Leaf-blades broad, pinnately decom- 

 pound. Umbels compound, the rays unequal. Involucres and involucels of entire 

 scarious-margined bracts. Sepals minute or obsolete. Petals white, somewhat 

 unequal, broadest above the middle, inflexed at the apex. Carpels short and thick, 

 with prominent wavy ribs: oil-tubes wanting. — ^Differs from Bupleurum in the 

 dissected leaf -blades and the small involucels.
