be especially a rendezvous of our more northern forms of Orchids. It is not 
unlikely that the summits of the White Mountains of Arizona still further 
north would show even a greater number. 
IRIDEZE. 
Iris Totmreana, Herb. Bot. Beechey.—South Park, Colorado, com- 
mon (967). Dr. Loew also collected an imperfect specimen from further 
south, probably New Mexico. 
SIsYRINCHIUM MucRONATUM, Michx. (S. Bermudiana, L., of Preliminary 
Report, 1874).—Regarded by Mr. Watson as distinguished from S. Bermu- 
diana, L, “by its low and usually very slender habit, the scape always 
terminated by a single spathe sessile within the terminal longer bract, and 
the flowers small, with segments setosely mucronate and capsules globose” 
(Proc. Amer. Acad. xii, p. 277). My specimen (945) from Colorado has 
larger flowers, and is probably somewhat out of range; still I regard it as 
belonging to this form. 
SIsYRINCHIUM BELLUM Watson (Proc. Amer. Acad. /. c.).—6-18' high; 
leaves narrow, smooth, shorter than the smooth stems; terminal bracts 
1-3’ long, not longer than the peduncle; spathes 2, enclosing 4-7 flowers 
and maturing 2-4 capsules, which are somewhat obovate and transversely 
wrinkled when mature; seeds obtusely angled and distinctly roughened, 
about 10 to the cell, light purple; petals 4-6’ long, toothed or slightly 
mucronate; stamineal column nearly 3” long and pubescent at the base. 
The stem is narrowly margined.—Zuni, New Mexico, 6,500 feet eleva- 
tion (171). 
Sisyrincuium Arizonicum, Rothrock, Bot. Gazette, vol. 2, p. 125.—1-2 
feet high; stem proper smooth, ancipital; leaves 6-12 inches long, 2-6 
lines wide, gradually attenuate into an acute point, 2—4 distinct white ribs 
in centre, and one or more less distinct toward either margin, minutely 
pruinose-glandular, slightly roughened on the margin; spathe of two 
lanceolate leaves regularly tapering to the top, somewhat shorter than the 
peduncles, of which each branch bears from 2—5 (most frequently 2); flowers 
yellow, 1-13’ in diameter, bright yellow segments of the perianth broadly 
lanceolate ; anthers 6 lines long, linear, twice as long as the dilated fila-
