486 ALLIUM. 



This species, though nearly allied to the former, differs in narrower 

 hollow channeled leaves, and the segments of the peria'nih being ob- 

 tuse and not pointed, it is also found mostly in cultivated fields, and 

 not in mountainous situations, as the other most frequently is. 



b. Filaments three-cleft. 



5. A. vine' ale, Linn. (Fig. 552.) Crow Garlic. Stem round, leafy 

 to the middle; leaves linear, round, fistulose; umbel bearing nume- 

 rous bulbs; stamens longer than the perianth ; three interior filaments, 

 three-cleft.

 British Flora, vol i. p. 160. Lindley, Synopsis, p. 268. 



Bulb small, ovate, white. Stem round, smooth, slender, finely 

 striated, erect, or somewhat curved at the base, from one and half to 

 three feet high, leafy to about the middle. Leaves long, round, smooth, 

 slender, tapering, and often withering before the umbel is expanded, 

 hollow, finely striated in the lower part at the back, and enveloping 

 the stem in striated sheaths. Bractea of two short deciduous pieces, 

 membranous. Umbel small, globose, with numerous crowded bulbs, 

 frequently without the intermixture of flowers, which when present are 

 not very numerous, elevated on slender purplish peduncles, swelling 

 upwards, long, but of irregular lengths. Perianth of six ovate obtuse 

 small segments, with green keels. Stamens with filaments longer than 

 the perianth, the three outer ones simple, awl-shaped, sometimes 

 twisted, the three inner dilated, thin, and membranous, deeply divided 

 into three slender awl-shaped segments, the central ones shorter than 

 the others, and bearing the small oblong purplish anther, of two cells, 

 bursting laterally. Style very short. Capsules rarely or never formed. 



Habitat. Dry pastures, corn fields, and waste places ; not unfre- 

 quent throughout England, the South of Scotland, and about Dublin, 

 in Ireland. 



Perennial ; flowering in June. 



*** Stem naked, leaves all radical. 



6. A. ursi'num, Linn. (Fig. 553.) Broad-leaved Garlic, or Ramsons. 

 Scape naked, obtusely triangular ; leaves elliptic, lanceolate, on long 

 footstalks; umbel simple, lax, without bulbs, nearly plane; stamens 

 simple, shorter than the perianth.

 British Flora, vol. i. p. 160. Lindley, Synopsis, p. 268. 



Bulb white, oblong, thin. Leaves one, two, or three, all arising 

 from the bulb, on slender obtusely angular footstalks, of variable 

 lengths, tapering into the mid-rib of the elliptic lanceolate leaf, which 

 is nearly plane, smooth, shining, bright green, with numerous slender 

 lateral parallel veins, connected with still more slender reticulations. 

 Scape obtusely triangular, solitary, erect, about as long as the leaves, 

 smooth, and terminating in a simple umbel, having at the base a pale
