* Stem leafy. Leaves plane or keeled ( not fislulnse'). Alternate filaments 
3-pointed, middle point bearing the anther. 
1. A. * Ampel6prasum L. ’(great round-headed G.) ; umbels 
globose, leaves linear keeled acuminate, stamens exserted, 
3 alternate ones deeply 3-cleft, middle point about as long as 
the entire part of the filament, spatha 1 -leaved long pointed. 
— a. umbels compact without bulbs. E. B. t. 1657. — /3. 1 
umbels loose, irregular, with many large bulbs. A. Babing- j

Rare. — a. On Steep Holmes Island in the Severn (the remains t 
of ancient cultivation). Guernsey. Great Arran Island, Galway * 
Bay; Ireland. — 0. Grade and Ruan Minor, Cornwall, (but only in ; 
or near orchards) ; near Little Bredy, Dorsetshire. Roundstone, t 
and South Isles of Arran, Co. Galway. If.. 8. — Bulb compound, of 
2 — 4 divisions. Stem 2 — 3 ft. high, with broad acuminate leaves, and ! I 
large heads of purplish-white flowers. Allied to A. Porrum, the | 
leek, in habit, but differing in its perennial and clustered young bulbs ; 
and as Ray states his plant to have a simple bulb, Mr. P. B. Webb 
concludes with justice that the one from Steep Holmes Island is A. 
Porrum. It is not known as a native of the western districts of t 
France, and A. Porrum itself is nowhere found truly wild. The speci- . I 
tic name, from apneKos, a vine, and irpaaov, a leek, means leek of the 1 
vineyard. Porrum, says Theis, is from pori, to eat, in Celtic ; whence | 
comes our word porridge. — The var. 0. differs almost solely by having i 
most of the flowers converted into large bulbs, a character which, j 
although employed to distinguish the species of this genus, indicates t l 
rather a disease than a distinct organism ; all the other characters I 
may be the effect of such metamorphosis. Mr. W. Andrews finds it I 
growing with A. Ampeloprasum in Great Arran Island, and considers | 
it only a variety. 
2. A. Scoroduprasum L. (Sand G.) ; umbels globose loose I 
few-flowered with numerous spherical (small) bulbs, stem leafy <j 
below, leaves linear flat, sheaths 2-edged, stamens included or ■ 
as long as the perianth, 3 alternate ones 3-cleft, middle point i 
shorter than the lateral ones and the entire part of the filament, I 
leaves of the spatha with a very short point. E. B. S. t. 2905. I 
A. arenarium L.: Sm. in E. B. 1. 1358 (as to the description, | 
but not the figure). 
Mountainous woods and fields, in sandy soil, principally in the 
N. of England and S. of Scotland, but not common. Portmarnock 
sands, Ireland. 2/.. 7. — Bulb simple, with numerous stalked purple 
offsets. Stem 2 — 3 ft. high, leafy below, terete, smooth, slender 
and wavy, yet firm and solid. Spatha usually single, scariose, short 
and broad, with a short point. Bulbs of flowers not so large as a pea. 
Flowers mostly few, never so numerous as the bulbs, on stalks usually 
much longer than the bulbs. This is not the Scoroduprasum of old 
authors, that name being sometimes given to A. Ampeloprasum, and
