hue. There is a monstrous variety of this species, found about 

 Rouen, which has the 2 carpels changed into petals, besides 

 having also the usual number of petals. 



Glaucous-leaved Bishop's-weed. Fl. June, July. Clt. 1816. 

 PL 2 to 3 feet. 



3 A. INTERMEDIUM (D. C. prod. 4, p. 113.) plant glabrous; 

 leaves all decompound, many-parted, greenish ; segments cut or 

 toothed : lower ones cuneated : upper ones linear-subulate, ser- 

 rated, and ending in long taper points. Q. H. Native of the 

 Pyrenees, and the kingdom of Naples. A. glaucif olium, Lapeyr. 

 fl. pyr. p. 144. An intermediate plant between A. glaucif olium 

 and A. Visnaga. It differs from the first in the leaves being 

 greenish, not glaucous, and in being tripinnate ; from the last 

 in the lobes or leaflets of the upper leaves being much acumin- 

 ated and serrated, and in the umbel spreading after flowering. 



Intermediate Bishop's-weed. PL 1 to 2 feet. 



4 A. VISNA'GA (Lam. diet. 1. p. 132.) stem terete, striated, 

 glabrous ; leaves decompound ; lobes or leaflets linear, cuspi- 

 date, divaricate ; rays of umbel contracted after flowering, and 

 indurated. 0. H. Native of the south of Europe, infields; north 

 of Africa, Caucasus near Kuby, and in plains towards the Caspian 

 Sea, and the Levant ; also in Chili, at Mendoza and Hacienda 

 de Vasquez, between Casa Blancaand Valparaiso. D. C. fl. fr.

 ex Smith, Gohoria, Neck. elem. no. 287. Garid. aix. t. 36. 

 Lob. icon. 726. f. 1. Umbels often not very much above the 

 leaves. Receptacle of the rays of the umbel not much dilated. 

 Rays crowded, very numerous, and at length they become so 

 hard as to be used as tooth-picks, hence the name of the plant 

 in France herbe aux cure-dents. In Spain, when they have 

 served this purpose, they are chewed, and thus are supposed to 

 be of service in cleaning and fastening the gums ; however this 

 may be, the leaves have a pleasant aromatic taste in the mouth. 

 Flowers witli white petals and purple anthers. 



Tooth-pick Bishop's-weed. Fl. June, Aug. Clt. 1596. PL 

 2 to 3 feet. 



5 A. DAUCOIDES (Salzm. pi. exsic. ann. 1825. ex D. C. prod. 



4. p. 113.) stem terete, striated, muricated, having a few scat- 

 tered bristles at the top of the petioles and branchlets ; leaves 

 bipinnate, rather ciliated ; leaflets linear, cut, acute ; leaves of 

 involucel either simple or trifid ; fruit covered all over with 

 small, obtuse tubercles. Q. H. Native about Tangiers. Habit 

 almost of Daucus. Umbels nearly as in A. Visnaga, having the 

 receptacle of the rays of the umbel thickened, and the rays very 

 numerous. Fruit ribbed, as in the rest of the genus, but differs 

 in being muricated. 



Carrot-like Bishop's-weed. PI. 2 feet. 



6 A. CRINI'TUM (Guss. pi. rar. p. 128. t. 25. prod. p. 332.) 

 stem terete, striated, glabrous, rather setose at the apex ; leaves 

 supra-decompound; lobes or leaflets linear-setaceous, glabrous; 

 petioles bristly ; margins of the sheaths of the petioles scarious ; 

 fruit glabrous, somewhat tetragonal. Q. H. Native of Cala- 

 bria and Sicily, in fields. Leaves of involucrum multifid, reflexed. 

 Flowers yellow in the dry ate, as in Daucus aureus. 



Hairy Bishop's-weed. PI. 2 to 4 feet. 



7 A. ANETHIFOLIUM (Lam. diet. 1. p. 132.) stem furrowed, 

 glabrous ; leaves decompound ; lobes or leaflets multifid, capil- 

 lary ; petioles channelled ; leaves of involucrum capillary, trifid. 



$ . 1 H. Native of the Levant, or Siberia. Daucus meoides, 

 Pers. ench. 1. p. 308. Umbels terminal, flat. Stem and rays 

 of umbel reddish. Fruit quite glabrous. Leaves of involucels 

 sometimes trifid. 



Fennel- leaved Bishop's-weed. Fl. Ju. Jul. Clt. 1818. PL 

 2 feet. 



8 A. PU'MILUM (D. C. prod. 4. p. 113.) stem erect, angular, 

 leafy, glabrous ; leaves bipinnate ; segments or leaflets pinnati- 

 fid ; lobes linear ; umbels opposite the leaves, pedunculate ; 

 leaves of involucels numerous, with scarious margins, and are 

 rather scabrous, as well as the rays ; some of the leaves of the 

 involucra are trifid at the apex. Q. H. Native of Portugal, 

 in sandy places, at the river Tavora, and elsewhere in Beira. 

 Sison pumilus, Brot. fl. lus. 1. p. 425. Fruit, according to 

 Brotero, like that of parsley. Lower leaves lika A. glaucifolium. 

 Petals obovate, unequally obcordate. Herb a foot high, not 

 dwarf. This is joined by Sprengel with Ptychotis verticillata, but 

 it is very distinct from that plant ; but from the obsolete teeth of 

 the calyx, and from the leaves of the involucrum being sometimes 

 trifid, it comes nearest to the present genus, although it may 

 hereafter form a proper genus, from the fruit being much more 

 angular ? 



Dwarf Bishop's-weed. PL 1 to 1| foot. 



9 A. BROUSSONE'TII (D. C. prod. 4. p. 113.) stem erect, 

 terete, leafy, glabrous, branched ; lower leaves unknown ; upper 

 ones tripartite : lobes cuneate-oblong, entire or tridentate ; leaves 

 of involucrum linear or rarely trifid ; young fruit rather scabrous 

 from adpressed short hairs. O- H. Native of Africa, proba- 

 bly about Mogador. Habit nearly of A. majus and A. glauci- 

 folium, but the involucra are very different. 



Broussonet's Bishop's-weed. Pi. 1 to 2 feet. 



10 A. CICUTA'RIUM (Willd. rel. in Schultes syst. 6. p. 531.) 

 stem angularly-furrowed, quite glabrous, furnished with few 

 leaves ; leaves ternately tri-pinnatifid : ultimate segments lanceo- 

 late, very acute, trifid ; umbels with 6-8 rays ; leaves of involu- 

 cra bipinnate : having the lobes or leaflets linear, and deeply 

 toothed. O- ? H. Native of South America, but in what place 

 is unknown. Plant small. Schlecht in litt. Petioles 3 to 4 

 inches long. Rays of umbel stiff, angular, shorter than the 

 involucrum. Leaves of involucel pinnatifid or trifid. Fruit 

 ovate, compressed from the sides, glabrous ; styles short, di- 

 verging. Ribs of mericarps rather prominent, having the fur- 

 rows between the ribs furnished with 1 vitta each, and the com- 

 missure with 2 vittae. 



Cicuta-like Bishop's-weed. PL 1 foot. 



* Species not sufficiently known. 



11 A.? PYRENA'ICUM (Lapeyr abr. p. 145.) stem glabrous, 

 flexuous ; leaves somewhat bipinnate ; lobes or leaflets entire or 

 cut, ultimate ones decurrent ; leaves of involucels setaceous or 

 trifid, twice the length of the umbellules. Q. H. Native of 

 the Pyrenees, in fields about Madres and St. Beat. The petals 

 are said by La Peyrouse to be rounded (arrondis) which indicates 

 that the plant does not belong to this genus. 



Pyrenean Bishop's-weed. PL 1 foot. 



12 A. RUBRICAU'LE (Horn. hort. hafn. 1. p. 272.) stem un- 

 known ; leaves somewhat verticillately tripinnate : leaflets capil- 

 lary ; leaves of involucel compound, longer than the umbellule. 



$ . H. Native of North America, near Baltimore. Perhaps 

 the same as A. anethifolium. 



Red-stemmed Bishop's-weed. PL 1 to 2 feet. 



Cult. The species of A'mmi are very showy while in flower ; 

 the seeds of them only require to be sown in the open ground 

 early in spring.
