Another species of this genus was found with the preceding, but 

 not in flower. It is entirely clothed with dense soft canescent pu- 

 bescence. It is shrubby, with long stout branches springing from 

 near the root. The leaves are oblong, coriaceous, entire, and two 

 inches or more in length. 



Several other undetermined Labiatse were found in the valley of 

 the Del Norte and on the Gila. 



BORAGINACEtE. 



Myosotis glomerata, JYutt. Tributaries of the Canadian. 



Euploca grandiflora, n. sp. Hirsute with rough oppressed hairs. 

 Leaves oblong-lanceolate, on short petioles. Flowers in leafy clus- 

 ters. Calyx five-parted to the base, with linear-lanceolate segments. 

 Corolla white; (the expanded limb nearly three-fourths of an inch 

 in diameter,) obscurely 5-lobed, plaited; tube slender, somewhat 

 ventricose below the middle; the throat naked. Stamens inserted 

 towards the base of the corolla-tube; the filaments short; anthers 

 oblong-linear. Ovary 4-celled, style filiform, persistent, arising 

 from the summit of the ovary; stigma capitate, with a tuft of stiff/ 

 hairs at the extremity. Fruit 4-celled, 2-lobed, finally separating 

 into indehiscent carpels; embryo curved, terete, surrounded with 

 very thin albumen; radicle superior. On the Del Norte below 

 Santa Fe\ This plant is clearly a congener of Euploca convolvulacea 

 of Nuttall. It is nearly related to Tournefortia.

 10, p. 183. A well characterized Californian genus, containing 

 three described species, one of which, the Wigandia Californica^ 

 Hook, and Am., was found in rocky places near the mouth of San 

 Carlos, on the Gila, and on the Cordilleras of California. The 

 leaves are coriaceous, varying in form from narrowly linear to lan- 

 ceolate, and from being perfectly entire to strongly dentate. The 

 upper surface (as well as the branches) is covered with a copious 

 adhesive varnish, while the under-side is whitish tomentose, with 

 strongly marked reticulated veins. 



POLEMONIACE^. 



Phlox, n. sp. This likewise occurs in Texas, and will be de- 

 scribed by Dr. Gray. It was found in various places on the tribu- 

 taries of the Canadian.
