nearly all of the flowers far enough advanced to open, had fully 
opened. At 6:00 P. M., none had closed. When the next obser- 
vation was made at 7:30, nine-tenths of the flowers had closed, and 
by 7:45 all were closed.”

YALLIUM FIBROSUM n. sp. PL. 29° 
Bulb with a fibrous coating; stem 2-3 dm. high, subterete, 
somewhat striate; leaves flat, thickish, 3 mm. wide, 1-1%4 dm. 
long; umbel with numerous bulblets and few flowers on pedicels 
about I cm. long; perianth-segments lanceolate-oblong, obtuse, 
6 mm. long; filaments slightly dilated below, 14 shorter than the 
segments, and a little longer than the style; anthers oblong; ovary 
evidently 6 crested, with short rounded crests. (Plate 300.) 
This somewhat resembles A. Canadense,from which it is dis- 
tinguished by the smaller size, the bright red bulblets, and the 
crests of the ovary. From A. reticulatum and A. Geyeri, it is 
easily distinguished by the presence of the bulblets. Collected on 
a high dry mountain side near Lima, Mont., June 29, 1895, by P- 
A. Rydberg, (no. 2606). : 
ALLIUM Sipiricum L, Mant. 562. 1767. (Allium Schaenoprasum 
&8L. Sp. Pl. 301. 1753. Allium Schaenoprasum Authors.) 
This has generally been confused with A//um Schaenoprasum, 
but it is evidently a good species. It is much taller than that 
_ plant, being generally 5-6 dm. high, has only one basal leaf and 
generally several stem-leaves, these thick, about 5 mm. in di- 
ameter, and broader perianth-segments. A//ium Schaenoprasum i: is 
only 2-3 dm. high, and its base is surrounded by nau narrow : 
leaves.
