acute, 1-nerved, not rigid but weak and crinkled in fruit: capsule 
very obscurely crested. : 
This species seems unique in its incised bracts. No. 1790 from barren gumbo 
clays, probably soft in the spring but becoming very hard, wholly devoid of 
other vegetation, House Creek, Owyhee Co., Idaho, June 29, 1912, is the type. 

Calochortus maculosus, n. sp.—Bulb narrowly ovate, about 1 
dm. below the surface, this and the underground part of the stem 
covered with coarse thick barklike coats: stems rather stout, 
smooth, 3-4 dm. high: leaves several (4-6), all abruptly expanded 
and scarious at the sheathing base: flowers 2, one on a spreading 
pedicel opposite the last bractlike leaf and also bracted; the other 
surmounting the main stem on a longer pedicel: sepals narrowly 
lanceolate, gradually long acuminate, 4-5 cm. long, greenish within 
and without: petals longer, 4.5-6 cm. long, abruptly acute and 
slightly crenate, white, or very pale blue, with a green band from 
apex to the large purple splotch above the yellow cuneate base, on 
which is the large gland, all the yellow area with long crinkled hairs: 
anthers 2 or 3-ribbed; obtuse, yellow, about equaling the filaments: 
capsule narrowly oblong. 
This, the fourth member of the macrocarpus group, is easily distinguished 
from C. bruneaunis Nels. and Macbr., its nearest relative, by the hairy lower 
part of the petal and the color, and from the others by the large purple blotch. 
In aspect it somewhat resembles the nitidus group, from which the elongat 
capsule readily separates it. The characteristic green band and the few- 
ribbed anthers are some of the characters which forbid its being referred to the 
Nuttallii group. The type is no. 2727 by HENDERSON, in loose soil on the hills 
near Lewiston, Nez Perce Co., Idaho, June 17, 1894.

Gen. Siph. nos. 1482 and 1504, and DRuce’s illuminating paper, 
Bull. Torr. Bot. Club 36:543. 1909). But is Helleborine so 
truly available? This question it seems to us DRUCE has 7s!

that while Hel’eborine was in use before 1753, it was not publis 
with species until Druck gives us the list that falls into the ater 
restricted as now understood. Druce’s aim was to bring meted 
into harmony with the Vienna rules, but these deny age y « 
uninomial nomenclature, a principle reasserted by the ai 
Congress. This seems long to have been an unwritten law, tor
