4 mm. long, 3 mm. wide, twice as long as the short tube : folds in 
the throat thick, each of 3 wart-like crests, the middle one largest: 
stamens on short filaments which are concealed by the large anthers, 
1 mm. long, inserted below the folds and alternating with them: 
scales at the base of the corolla tube fleshy, in pairs: style short: 
stigma capitate : nutlets ovate, 3 mm. long, 2 mm. broad, the sur- 
face pubescent and having a few barbed bristles which are .5-2.5 
mm. long, generally a long and short one alternating. 
This beautiful species grows in the cafions of Mesa Verde in 
southwestern Colorado whére the cliff dwellings are situated. 
The type specimens were collected by the author in Navajo Cafion, 
June 7, 1892. 
Type in the herbarium of California Academy of Sciences. 
‘ Corydalis Wetherillii 
Annual or biennial, branched from the base and also above, 
with slender, erect stems and branches, 10-15 cm. high, glabrous 
and glaucous: leaves dissected, the lower on long slender petioles, 
twice-compound with 5 primary divisions on capillary petiolules, 
secondary divisions fan-shaped, 3—5-parted with ultimate divisions 
spatulate, entire, or 3-lobed, acute, minute : peduncles axillary from 
near the base to the top of the stems, 1 mm.—2 cm. long, with 1-3 
flowers at summit as well as some abortive ones : bracts linear-act’ 
minute, entire or with a few teeth nearthe summit : sepals 2, mem 
branous, triangular, scale-like, less than 1 mm. long: corolla 2 cm 
long, the spur rounded at base, straight, 4 mm. long : outer petals 
pinkish, hooded but without dorsal crests ; inner yellowish, as long 
as the outer, with wing-like crests on the back: capsules secs 
or linear-lanceolate, straight or somewhat curved, 2 cm. long, 
tipped with the persistent style and disk-like stigma : seeds /- 
tened, orbicular, black, very glossy, 2 mm. in diameter, faintly 
marked under a 10-diameter lens with a fine quadrangular venation. 
This peculiar species was collected near Bright Angel Creek, 
one of the branches of the Colorado River which comes into . 
river nearly opposite Hans’ Trail. This trail is that taken by 
tourists who go into the cafion from the Flagstaff side. It is nam 
in honor of Mr. Alfred Wetherill who collected it in the summer 
of 1897. ; 
The foliage is more finely dissected than in any other specie 
_ known to me. It is perhaps more nearly related to the gr 
which contains C. aurea but it is quite distinct from that oF she 
other known species. The type is in the herbarium of the | 
fornia Academy of Sciences.
