120 UNITED STATES AND MEXICAN BOUNDARY. 
dens, Durand, Рі. Herrm. Dr. Bigelow gathered it at Albuquerquc, New Mexico, when in 
Whipple’s expedition ; and Fendler’s No. 583 is a narrow-leaved form of the same species.

places near San Diego, California, March ; Dr. Parry. 
ORTHOCARPUS DENSIFLORUS, Benth. 1. c. Dry hill sides, Monterey, California, April. Stem 
nearly simple, but the specimens are early ones, and later in the season no doubt the plant 
becomes much branched. Lower leaves simple, tapering to a very long narrow point. Appendages 
of the lower lip rather obtuse.

CoRDYLANTHU LAXIFLORUS (sp. nov.): paniculato-ramosus, hirsutissimus, sublandulosus ; foliis 
linearibus brevibus integerrimis rarius trifidis ; floribus solitariis vel in ramulos breves adproxi- 
matis unibracteatis; calycis lobo postico apice bidentato; corolle labio inferiori saccato subin- 
tegerrimo ; antherarum loculo altero abortivo seu in stam. brevioribus plane nullo.— Rocky hills, 
| Sonora, Mexico; Thurber. Also Great Salt Lake; Col. Frémont, 1843. Plant branched from 
the base, 1 or 2 feet high, turning dark colored in drying, very hirsute throughout with rather 
viscid and and sometimes rather glandular spreading hairs; branchlets very numerous, short, 
very leafy throughout, bearing from one to four or five flowers. Leaves to 9 lines long, about 
a line wide. Calyx half an inch long, almost equalling the “ bright yellow ” corolla. Galea 
nearly straight, broad. Anthers one-celled and with a minute pendulous vestige of the second 
cell, at least in the longer stamens. A true congener of the Californian species, remarkable for 
its scattered flowers, and for the abortion of the smaller anther cells. 
CoRDYLANTHUS WRIGHTII (sp. nov.): paniculato-ramosus, glabellus, minute glandulosus; 
foliis 3-5-partitis filiformibus; bracteis conformibus haud ciliatis ; floribus subcapitatis ; calycis 
lobo postico 2—3-dentato; antherarum loculo altero pendulo etiam in staminibus brevioribus 
manifesto. Prairies, from 6 to 30 miles east of El Paso, Western Texas; Wright, (150. Sand 
hills, Chihuahua; Thurber. This, far the most eastern of the genus, was first met with by Mr. 
Wright, who found it only in the autumn of 1849, in his first expedition, which was attended by 
many hardships, but which was very rich in its botanical results. This species is nearly related 
to C. filifolius ; but it is not so rigid, has finer foliage (without hispid hairs,) less capitate and 
larger flowers, the more incurved corolla an inch and a quarter long, and the upper lip of the 
calyx is more or less 2—3-toothed or cleft at the apex. Seeds elongated-oblong, deeply farove- 
reticulated. - : 
CORDYLANTHUS FILIFOLIUS, Nutt.; Benth. in DC. Prodr. 10, р. 597, California, (station not 
recorded, but probably Monterey ;) Parry, Shelton. The middle lobe of the involucral bracts 
is somewhat dilated at the extremity and truncate-emarginate. 
PEDICULARIS CENTRANTHERA (sp. nov.): acaulis, glabra; foliis pinnatifidis scapum bis supe- 
rantibus, segmentis ovatis duplicato-dentatis margine denticulisque subcartilagineis discolo- 
ribus (albis ;) spica oblonga densiflora ; calycis cylindracei dentibus 5 aequalibus lanceolatis 
albido-marginatis ; corollae galea cucullata erostri edentula labio inferiore patente paullo lon- 
giore; filamentis glabris; antheris basi eximie bicalcaratis,—New Mexico, and on Ben More, 
April, Bigelow ; the specimens from the latter locality nearly past flowering. This is unlike 
any other Pedicularis that I know of, and is distinguished by its awned or spurred anthers from 
all known species except P. grandiflora, Fisch., with which it has little else in common. The
