186 PITTONIA. 
VERBENA PUBERA. Perennial, stoutish, the many stems 
decumbent, only 3 to 10 inches high, densely clothed with 
subsessile bipinnatifid leaves, ending in a thick subsessile 
spike; pubescence dense, hirtellous, somewhat viscid; ulti- 
mate leaf-segments oblong-linear; bracts short, not half the 
length of the calyx, lanceolate, nerveless: calyx-segments 
merely acute: corolla large, rose-red, the tube well exserted: 
nutlets large, nearly filling the short calyx. 
Davis Mountains, 28 April, 1902, n. 337, typical. I also 
refer to the species n. 162 from the foothills of the same 
range. Though related to V. bipinnatifida, Schauer, which is 
a rather tall, erect annual, with a harsh and long bristly 
pubescence, this must be held distinct by its perennial root, 
and very different habit and pubescence. Mr. Tracy’s 2. 
162* may, however, be a hybrid between the two. 
VERBENA PULCHELLA. Evidently a winter annual, the 
several stems nearly erect, 3 or 4 inches high and simple, 
each with 4 or 5 pairs of leaves, and a large subsessile ter- 
minal spike; pubescence rather sparse, hirsute, the calyx 
also minutely glandular beneath the scanty hairiness, but 
not viscid: lowest leaves simple, ovate, entire; those next 
above cuneate-obovate, petiolate, deeply 5-cleft ; cauline 
ternately divided and the divisions trifid, the whole leaf 
subsessile, shorter than the internodes, about 4 inch long: 
bracts subulate-lanceolate, 1-neryed, appressed to the calyx, 
not equaling it in length; calyx-teeth short, acute: corollas 
large for the plant, apparently pale-pink. 
Foothills of the Davis Mountains, 23 April, 1902. A® 
elegant little species allied to V. bipinnatifida ; possibly some- 
times perennial, for it has partly the habit of that group, 
but in the specimens even the cotyledons are obvious, while 
the plants are in late flower and early fruit.
