In open hilly places, but very rare. 



Found by Mr. Newton on the Holms island, in the mouth of the 

 Severn. Ray. On the Steep Holms, in August 1803, Mr. F. 

 B. Wright. 



Perennial. August. 



Bulbs white, globose, increasing rapidly in a garden, by lateral off- 

 sets, till they compose a mass as big as a man's head, resem- 

 bling a bunch of grapes ; whence, I have sometimes thought, 

 the old Greek name of the plant, Ampeloprasum, Vine Garlick, 

 might have originated ; but a name of similar construction has 

 been applied to several species from their growing in vineyards. 

 In this lu.\uriant condition it rarely produces^oti'ers. Otherwise 

 the stems are solitaiy from each bulb, 2 or 3 feet high, erect, 

 round, solid, simple ; leafy in the lower part. Leaves alternate, 

 flaccid, flat, linear, near an inch broad, taper-pointed, slightly 

 keeled, single-ribbed ; sheathing at the base ; rough with mi- 

 nute teeth at the edges, and at the top of the keel. Stipula 

 membranous, tubular, undivided, within the sheath of each leaf. 

 Umbel solitary, erect, of innumerable light-purple Jloivers, on 

 angular stalks, with a large, concave, deciduous bractea, includ- 

 ing many small interior ones. Fl. uniform, not large, unac- 

 companied by bulbs. CoroZ/a bell-shaped. Pef. ovate, concave, 

 all rough at the edges and keel. Stam. broad and flat ; 3 of 

 them simply pointed ; 3 alternate ones with a long slender 

 point, at each side of that which bears the anther. Germen py- 

 ramidal. Style triangular. The scent of the whole plant is 

 strong, and of the most disagreeable kind. The nature of the 

 perennial bulbs sufficiently distinguishes this species from the 

 Leek, A. Porrum, however similar their herbage, 



2. A arenarium. Sand Garlick. 



Umbel globose, bearing bulbs. Stem leafy below. Leaves 

 flat, with cylindrical sheatlis. Bracteas obtuse. Three 

 alternate stamens dilated, three-cleft. Keel of the petals 

 roughish.
