114 PITTONIA. 
Type specimens from Golden City, Colorado, collected by 
myself in 1871, and then mistaken for V. Americana from 
which its entire or subentire foliage and the longer and 
almost acute capsules require that it should be distin- 
guished. 
VERONICA CRENATIFOLIA. Smaller than the above, more 
slender and diffuse, freely creeping, 4 to 8 inches high, — 
glabrous, not glauceous, but the herbage of a singularly 
light green: leaves 4 to 14 inches long, all petiolate, the low- 
est suborbicular or round-oval, the upper and larger nearly 
all elliptical, all but the very uppermost crenate rather than 
serrate, but some of the lowest and smallest entire: racemes 
and petioles very slender, the flowers rather few: sepals 
somewhat oblanceolate. 
The type of this is Baker, Earle and Tracy’s n. 33, from 
along the Mancos River in southern Colorado, 22 June, 
1898, distributed for V. Americana. 
Tiss LUTEOLA. Annual, with a dense system of rigid, 
stoutish, yellow-green, glabrous, short-jointed branches, each 
plant forming a mat 5 to 10 inches broad, yet not prostrate, 
erect-spreading rather; leaves short, linear, subterete, pun- 
gently acute, glabrous, yellowish ; stipules deltoid, acumi- 
nate: bracts and pedicels of the dense inflorescence glandu- 
lar-villous, as also the broad green midrib of the otherwise 
scarious sepals: petals exceeding the calyx, apparently 
white: seeds minute, reddish-brown, broad] y semiobcordate, 
none winged, but all minutely roughened by subsessile 
glands, especially around the thick obtuse margin. a
