Orthocarpus dbnsiflorus, Benth. I. 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 

 of the lower lip rather obtuse.

CoKDYLANTHU LAxiFLORUS (sp. 110 V. ) : paniculato-ramosus, hirsutissimus, sublanclulosiis ; foliis 

 linearibus brevibus integerrimis rarius trifidis ; floribus solitariis vel in ramulos breves adproxi- 

 raatis unibracteatis; calycis lobo postico apice bidentato ; corollse labio inferior! saccato subin- 

 tegerrimo ; aatherarum loculo altero abortivo seu in stam. brevioribus plane nullo. — Rocky bills, 

 Sonora, Mexico; Thurher. Also Great Salt Lake ; Col. Fremont^ 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 6 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. 



CoRDYLAKTHUS Wrigiitii (sp, nov.) I paniculato-ramosus, glabellus, minute glandulosus; 

 foliis 3-5-partitis filiformibus; bracteis conformibus hand 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^ (450.) Sand 

 hills. Chihuahua ; TJiurher. This, far the most eastern of the genus, was first met with by Mr. 



Alright, 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.

 recorded, but probably Monterey ;) Parry, Shelton. The middle lobe of the involucral bracts 

 is somewhat dilated at the extremity and truncate-emarginate.
