574 Cotton: THREE NEW PLANTS FROM WASHINGTON 
' Orthocarpus barbatus 
Annual, slender, erect, simple or sometimes sparseyl branched 
above, 10-20 cm. high, minutely pubescent and sparsely hispid : 
leaves 2-4 cm. long, deeply 5-cleft, the lobes linear-attenuate ; 
uppermost leaves passing into the bracts of the spike: spike 3-5 
cm. long, its bracts oblong, acute, 10-15 mm. long, about 7 mm. 
wide ; the lower ones more or less 3—5-cleft, the upper merely 
3-5-toothed : calyx sparsely hispid, 9 mm. long, its lobes deeply 
2-cleft into subulate teeth; teeth nearly as long as the tube: 
corolla yellow, 12 mm. long, with a simply saccate lip incon- 
spicuously 3-toothed, and a moderately smaller triangular galea 
whose tip is straight and surpasses the lip about 1.5 mm. and is 
densely pubescent ; the rest of the corolla nearly glabrous : anthers 
2-celled, the cells equal, oblong, and covered with a few long 
hairs ; capsule ovoid, acute, dark brown to blackish. 
This species is closely allied to O. tenuifolius Benth., but is dis- 
tinguished by its acute bracts, and its galea which is straight and 
densely pubescent. The rest of the corolla is nearly glabrous 
while in O. tenuifolius it is finely puberulent. The capsule 1s 
broader just below the middle, not elliptical as in O. tenuifolius. 
Type collected at the junction of Crab and Wilson creeks, 
Douglas county, 19 June 1893, Sandberg & Leiberg, 234-
