acute or acuminate, strongly nerved and rigid in fruit. — A. reticulatum, 
var. 8, Watson, King’s Rep. 5. 486. Idaho to Washington Territory 
and Oregon (n. 226, Geyer; n. 546, Hall & Harbour; n. 3886, Howell; 
Spalding ; Wyeth). 
* * Bulb-coats not fibrous; some of the outer membranous coats in most 
species marked by a more or less distinct peculiar reticulate venation : 
leaves several (2 to 4), shorter than or about equalling the scape: spathe 
2-valved, except in n. 21: stamens and style exserted only in n. 20 and 21. 
+ Ovary not crested or obscurely 3-crested: perianth-segments not serrulate. 
++ Scape usually tall (a foot high or more). 
12. A. scaposum, Benth. Outer bulb-scales dark, with coarse 
more or less regular vertically oblong rectilinear reticulation : umbel 
loose, rather few-flowered: perianth-segments white with red midvein, 
lanceolate, acuminate, 3 or 4 lines long. — Watson, King’s Rep. 5. 487, 
t. 38, f.10,11. W. Texas to S, Arizona and Mexico. This is probably 
identical with the older A, Kunthii, Don (Schenoprasum lineare, 
HBK.) 
++ ++ Scape low. 
13. A. Dovueiasiu, Hook. Reticulation of bulb-coats not detected : 
scape 8 or 10 inches high: flowers pale rose-color, 3 or 4 lines long ; 
segments lanceolate, acuminate, scarcely exceeding the stamens and 
style: ovary not at all crested. — Oregon (“ Blue Mountains, subalpine 
hill near Kettle Falls,’ Douglas). A very obscure species, not iden- 
tified in recent collections. The figure and description in Hook. FI. 
Bor.-Am. refer, with the exception of the scape and the details of the 
flower, to his var. B, 1. e. to A. Tolmiet, Baker. 
14. A. mapiIpum. Bulbs white, bulbiferous at base, without re- 
ticulation: leaves 2, thick and channelled, 1} to 3 lines broad: scape 
stout, angled, 4 to 8 inches high: flowers usually many, on pedicels 
4 to 6 lines long, white or nearly so, 4 lines long; segments ovate- 
oblong, acute, a little exceeding the stamens: cells of the ovary with 
two fleshy ridges at the summit.— Union County, Oregon; W. C. 
Cusick, n. 8382. In small streams or wet places in high ground. 
15, A. Cusick. Reticulation of bulb-coats not detected: leaves 
2, flat, somewhat falcate, 3 lines wide: scape 3 or 4 inches high: 
flowers rather numerous, on pedicels 6 to 8 lines long, nearly white, 
4 or 5 lines long; segments lanceolate, broadly acuminate, nearly 
twice longer than the stamens and style: ovary-cells shortly apicu- 
late. — Union County, Oregon; W. C. Cusick, n. 179. 
16. A. coLiinuM, Dougl. in herb. Known to me only from scanty 
flowers from Kew Herb. Perianth-segments ovate-lanceolate, acute,
