(2 lines long), rather dry and chaffy within. — Same locality (L) ; 

 "Chalate" or " Lalate." 



Alnus acuminata, HBK. A tree, 20 to 30 feet high and 1 or 2 

 feet in diameter. — Cumbre (83'J), growing among pines and oaks. 

 The bark is used for dyeing blankets. 



QuERCUs Emoryi, Torr. A tree, 10 to 20 feet high and 1 to 1|- 

 in diameter. — Yerba Buena (302), on poor grassy hills. The acorns 

 are sweet, and much used by Indians and Mexicans. 



JuNiPERUS PACHYPHLCEA, Torr. — A tree, 15 or 20 feet high and 

 2 or 3 in diameter. — Norogachi (UU) ; berries eaten. 



PiNUS Chihuahuana, Engelm. A tree, 20 to 25 feet high and 1 

 or 2 in diameter: leaves 2 to 5 in the sheath: cones 2 to 2i inches 

 long. — Yerba Buena (301). 



PiNUS CEMBROIDES, Zucc. A " scrub pine," 20 or 25 feet high and 

 2 in diameter. — Yerba Buena (303). 



Pixus Engelmanni, Carr. About GO feet high and 3 to 5 feet 

 in diameter, with short heavy branches : leaves usually in fours, 



— Norogachi (500). The specimens agree satisfactorily with Dr. 

 Engelmann's description of the single specimen collected by Wis- 

 lizenus in 1846. Palmer states that the Indians make of the cone 

 a good and durable hair-brush by bruising off the corky portion of 

 the scales. 



Spiranthes Madrensis, Benth. & Hook.? The same as 1523 

 Coulter, 521 Pringle (1885) from near Chihuahua, and 477 Lemmon 

 (1881) from Rucker Valley in Arizona. It agrees fairly well with 

 Reichenbach's description of Seemann's plant from the Sierra Madre. 



— Norogachi (409). 



NoLiNA ? Leaves only. — Hacienda San Miguel (241). 



Dastlirion ? Leaves only. — -Cumbre (340) ; the leaves are 



made into baskets, after removal of the spines.

 ends : leaves spreading and subfalcate, G inches long and 4 or 5 lines 

 broad : stem erect, 2 feet high or more, branching above, smooth, with 

 several (about 6) appressed scarious bracts an inch long; floral bracts 

 small : pedicels fascicled, jointed near the base, equalling the yellow 

 flowers (6 lines long) : capsule broadly elliptical, 3 lines long. — Dis- 

 tinguished from the ordinary species by the short falcate leaves, the 

 more numerous cauline bracts, shorter capsules, etc. Hacienda San 

 Miguel (229).
