GERANIACEAE. 
Geranium eremophilum Wooton & Standley, sp. nov. 
Perennial from a slender, branched caudex; stems erect or ascending, very 
slender, 30 cm. long, much branched, minutely retrorse-pubescent, not glandular; 
leaf blades somewhat pentagonal in outline, 85 to 45 mm. broad, in age gla- 
brate, when young sparingly pubescent, 3 or 5-lobed, the divisions with abruptly 
acuminate, ovate teeth; pedicels slender, glandular; sepals oblong-lanceolate, 
about 10 mm. long, ending in an awn 2 mm. long, more or less pubescent, not 
glandular; petals purplish pink, obovate, retuse, 15 to 20 mm. long; style column 
canescent or rarely glandular; carpel bodies sparingly hirsute; seeds reticulate. 
Type in the U. 8S. National Herbarium, no. 233003, collected in the San Luis 
Mountains, September 5, 1893, by Dr. E. A. Mearns (no. 2142), 
ADDITIONAL SPECIMENS EXAMINED: San Luis Mountains, September 26, 1898, 
Mearns 2443; San Luis Mountains, September 11, 1898, Mearns 2194; Organ 
Mountains, alt. 1,800 meters, September 23, 1906, Wooton & Standley. 
It seems undesirable to describe any additional species of Geranium in this 
group where the species are so closely related and so poorly known, These 
plants, however, could not be placed under any name in Dr. Rydberg’s recent 
revision of the genus without stretching specific limits more than seems reason- 
able. This species is near G. fremontii and G. caespitosum, but is more slender, 
has paler, rather larger flowers, scarcely any glandular pubescence, and nearly 
glabrous leaves with broader, blunter segments. 
Geranium lentum Wooton & Standley, sp. nov. 
Perennial with a stout caudex ; stems weak, slender, ascending or spreading, 
30 to 60 em. long, branched, densely glandular-villous; leaf blades reniform- 
pentagonal, 35 to 45 mm. wide, dull green, thin, glandular-hirsute on both 
surfaces, 5-parted, the divisions cuneate and with rounded obtuse teeth ; 
petioles very long and slender, densely glandular; pedicels long and slender, 
glandular; sepals elliptic-oblong, tipped with an awn less than 1 mm. long, 
glandular-pilose; petals white, 7 to 10 mm. long; style column densely glandu- 
lar; seeds finely reticulate. 
Type in the U. S. National Herbarium, no. 561079, collected on the West 
Fork of the Gila, August 7, 1900, by E. O. Wooton. 
ADDITIONAL SFECIMENS EXAMINED: Craters, Valencia County, July 28, 1906, 
Wooton; Rio Zuni, July 28, 1892, Wooton; West Fork of the Gila, August 6, 
1900, Wooton; Middle Fork of the Gila, August 5, 1900, Wooton. 
The specimens cited here have passed as G. wislizeni, a Mexican species, 
Apparently none were examined in the preparation of the Geraniaceae for the 
North American Flora, for no description in that work agrees with our plant. 
Geranium wislizeni is the plant to which this is most closely related, but that 
lacks the dense glandular pubescence characteristic of our plant, being glandu- 
lar only on the style column. 
LINACEAE. 
Cathartolinum vestitum Wooton & Standley, sp. nov. 
Annual, 15 to 25 cm. high; stems slender, striate, densely puberulent, simple 
below, branched above the middle. the branches strongly ascending; leaves 
small, linear-lanceolate, glandular-denticulate, acute, thick, glaucous; bracts 
linear-lanceolate, 3 to 4 mm. long, aristate-tipped:; floral branches slender, 6 
to 35 mm. long; sepals lanceolate, 5 or 6 mm. long, acute, bristle-tipped, with 
many glandular teeth on the margins, puberulent on the nerves; petals bright
