have it from Rock Springs, Texas, April 16, 1930; Ozona, April 13, Sonora, 
April 14; North of Del Rio, April 17, and at t Del R Rio. Shorter and less 
slender forms but crestless with slightly longer flowers arer from Rodeo, 
\A. reticulatum differs only in the strong central crests and in being a little 
stouter. The flowers have a tendency to be bluish along the midrib, and the 
bulbs are often several in a cluster. I have it from Indian Hot Springs 
along the Rio Grande, April 30, 1930; Sierra Blanca, April 10, 1930; Del 
Rio, April 20, 1930, Lordsburg, N. M., May 5, 1930. The character sepa- 
rating this species from Nuttallii is only the crested ovary, a somewhat shaky 
Allium Bigelovii Watson. This well marked species is less than six 
inches high from the bulb which is 2-3 inches deep in the ground. The 
leaf is single and arcuate but not flattened nor wide, and overtops the 
flowers. The umbels are large and about 20-flowered, with rather stout 
pedicels 34 inch long, and with the white flowers with conspicuous and 
deep red midribs and tips, and segments about half an inch long and lance- 
ovate-acuminate. The crests are central, erect, petal-like and nearly as long 
as the capsules. The bulbs are globose-ovate, about an inch long and with 
deep reddish-brown outer coats separating readily. The bulbs propagate as 
in A. bisceptrum but without runners. The markings on the coats are well 
figured by Watson Bot. King, t. 38 f. 8 and 9. The walls of the meshes 
are a little uneven but not really sinuous as in A. bisceptrum. 
53a near tip is about the same, as given by me in Cont. 10. I found this only 
growing in the live oaks west of Silver City, N. M., May 5, 1930. 
Allium Coryi n. Sp. Allied to reticulatum group. Growing on 
capes plains at Alpine, Texas, ie 26, 1930. Plants about six inches to 
oot high, slender, erect, with 2 3 basal leaves half as long as peduncle 
which are very narrow and sienlhe Bulbs ovate, with very many yellowish- 
brown reticulated coats from which the very thin and hyaline membrane has 
in Nuttallii. Sheaths of the umbels about as long as pedicels (1-2 inches). 
Pedicels slender. Flowers about 10, chrome-yellow, 3-5 mm. long, rather 
ovate. Perianth segments oblong-ovate triangular-acute, the outer ones with 
strong midrib. Ovary globose, crowned with thin and flat low crests on the 
angles. Odor inten One tries very hard to put this in Nothoscordium, 
but the bulbs and color are that of an onion. This is the only native yellow 
onion. Anthers elliptical, on filaments nearly as long as the perianth. Ded- 
icated to V. L. Cory of Sonora, Texas, an indefatigable botanist. 
Nothoscordum Texanum N. Sp. Bulbs depressed-globose, about 2 inch- 
es wide when mature, of many hyaline and very thin coats onion-like, the 
i ee being much like those figured in No. 52, second figure, in my Cont. 
;w and at the base of the bulbs are produced one to several shining 
bulblets within the coats. The stems are 1 to 1 1-2 feet high and erect and 
slender and about as long as the very narrow leaves which are uniform in 
width and basal and about four. Bracts hyaline, about an inch long, two,
