152 PITTONIA. 
v VERBENA RUDIS. Allied to V. bracteosa, but the numer- 
ous assurgent or nearly prostrate stems from the branching 
crown of a hard thick woody perennial root: stems less 
distinctly angular, and pubescence more softly hirsute: 
leaves cuneate-obovate, variously incised or subpinnatitid, 
their sparse pubescence closely appressed: spikes loose and 
bracts only half as long as in V. bracteosa. 
Arboles, southern Colorado, 18 June, 1899, C. F. Baker. 
Said to be a common weed of roadsides and cultivated 
lands. Its remarkably thick hard woody perennial roots 
alone would completely separate it from V. bracteosa. 
^ VERBENA CONFINIS. Also allied to V. bracteosa, and the 
root annual, but rather tall much branched stems apparently 
erect or ascending; herbage greener, but under a lens ap- 
pearing sparsely hirsute: leaves distinctly 3-lobed, the two 
lateral lobes short and divaricate, the middle one many 
times larger and cuneate, incisely toothed or cleft: spikes 
elongated and very lax, many of its bracts and flowers in 
opposite pairs, the bracts smaller and narrower than in 
V. bracteosa. 
Organ Mountains, New Mexico, 30 Aug., 1897, E. O. 
Wooten (his n. 409 of my set). I know so much, by field 
experience, about verbena hybrids, and even of such as 
have V. bracteosa for one parent, that this plant would have 
been under suspicion but for the fact that, while Mr. Wooten 
called it V. bracteosa, his collection contained neither that 
species nor any other which, with V. bracteosa, could have 
generated this. I am therefore convinced that it is a proper 
species. 
“ CHRYSOTHAMNUS BAKERI. Low, compact, the crowded 
erect flowering branches only 5 to 7 inches high, from a much 
branched woody caudex and thick hard-woody root: bark 
of flowering branches glabrous and white ; leaves about an 
inch long, narrowly linear, deep-green and glabrous, but
