and woolly, as well as glutinous. It is occasional in Western Utah 
and Eastern Nevada. 
CENOTHERA JOHNSONI Parry Am. Nat. 9, p. 270. This very 
poorly described plant is said to have elongated stigmas, petals an 
inch long, calyx tube not shorter than the leaves, capsules 9 to 12 
lines long, somewhat 4-angled, strongly nerved, not crested, and 
to resemble CZ. primiveris, and to be very common at St. George, 
Southern Utah. The species which I have collected abundantly in 
Western Utah and Eastern Nevada is perennial, czespitose from a 
many-branched root, which is covered at the summit with the dead 
petioles of former leaves, acaulescent or stems an inch or two long; 
leaves lanceolate, gradually decurrent into the petiole, which is 1 
to 3 inches long, and never more than % the length of the blade; 
blade entire or undulate, or irregularly and sparsely dentate with 
sharp teeth; whole plant hoary with a dense, soft, and very short 
pubescence; calyx tips free in the bud; calyx splitting on one side 
and reflexed in flower, lobes 1 to 114 inches long, tube 3, to 5 inches 
long and erect, with 8 striz; petals rhomboidal, entire or slightly 
lacerate on the edge; 2 to 3 inches wide, and 2 to 2% long, golden 
yellow, palmately veined with 3 very prominent and several inter- 
mediate veins, each feather veined in addition; the petals, in drying 
and fading, turn red, and resemble the meshes in the web of a frog’s 
foot; stamens % line wide and 6 lines long, versatile, yellow; stigma 
lobes 4 to 6 lines long, 4 line wide; capsule ovate, broadly winged, 
not nerved or veined, less than an inch long, not crested, hoary 
white; calyx also with scattered, fine, long, white hairs. 
This grows on sunny southern slopes in very dry places, blossoms 
in June, and is by far the handsomest species of the genus. It is 
vespertine. Rather common in Western Utah and Eastern Nevada 
at 6,000 feet altitude. Should it prove to be new, I name it Gno- 
thera Howardi, after Mr. A. M. Howard, the gentleman in my party 
who saw it first. 
ECHINOCACTUS PAPYRACANTHUS Eng. The flowers are an inch 
long, opening but little; stigma cleft a line deep into 6 anther-like 
divisions, papillose on the sides and upper surface; filaments 6 lines 
long; style almost as long as the petals, '4 a line thick, linear; the 
flowers open in the morning, and close in the afternoon, but appar- 
ently are not affected by cloudy weather. This grows in alkaline 
soil, and blooms in May. It is scarce everywhere.
