34 PITTONIA. 
monly rather obscure; scapes ancipital, each of the broad, 
sharp-edged subentire wings strongly 3-striate: spathes 
mostly solitary, their bracts very unequal, the outer of more 
than twice the length of the inner and 13 to 2 inches long: 
perianths apparently dark-purple; capsules large (nearly 1 
inch in diameter), almost globose, very sparsely hairy. 
Meadows along the Mancos River, southern Colorado, 
Baker, Earle and Tracy (n. 113), 25 June, 1898; also by the 
same on Chicken Creek in the La Plata Mountains, at 9,000 
feet, 7 July (n. 377). A large and doubtless showy species, 
exceeding even the Californian S. bellum in size. 
Ý 5. HALOPHILUM. Low and slender, tufted, wiry and glau- 
cous, the fibrous roots coarse but rather soft: narrow leaves 
about half the length of the scape, and very strongly 5-7-stri- 
ate: scapes5to8 inches high, tereteand very narrowly winged 
rather than ancipital, one of the wings, even, occasionally 
almost obsolete: spathes small, solitary, their bracts nearly 
equal: perianth not seen: eapsules small, pyriform, scabrous- 
pubescent, containing few and large seeds, these dull-black, 
nearly smooth. 
Collected at the Humboldt Wells, near Wells, Nevada, 25 
July, 1893, in fruit only.” The species bears some superficial 
likeness to another halophilous species belonging to Arizona, 
i. e, S. demissum, discovered by me in 1889, near Flagstaff. 
But that has very numerous and almost minute seeds with 
a very rough testa; it also has a branching stem bearing two 
or more spathes. Here the stern or scape is perfectly simple 
and unispathaceous, the seeds being few, large, and with an 
almost smooth testa. It is more than possible that this 
Humboldt Valley plant may prove to have a wider distri- 
bution, and be found to include certain flowering specimens 
which are rather numerous in my herbarium, from various 
points in western Nevada, and from Californian stations 
east of the Sierra.
