1648 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM 



lACISTEMACEAE. 



Page 156. Lacistema myricoides should be placed in synonymj' under the 

 following name: Lacistema aggregatura (Berg) Rusby, Bull. N. Y. Bot. 

 Gard. 4: 447. 1907. Piper aggregatum Berg, Act. Helv. 7: 131. pi. 10. 1777. 

 This species has been collected in Sinaloa, where it is known as "guayparin." 



SALICACEAE. 



Page 158. Populus angustifolia. The Gosiute Indians of Utah use the 

 young shoots of this species for basket making. A kind of honey dew produced 

 on the under side of the leaves by aphids is gathered and used in much the same 

 way as sugar. 



Populus monticola. A synonym is Populus brandegeei Schneider, 111. Handb. 

 Laubh. 1: 23. 1904. It is probably this species of which Clavigero writes 

 (Historia de la California, 1789): "The guaribo, the largest tree of California, 

 is so like the cottonwood [dlamo, of Spain] that at first glance it can not be dis- 

 tinguished; but nevertheless it is quite different in the quality of the wood, which 

 is very good for rafters and all kinds of construction. Unfortunatel^y, this tree 

 grows only in a few rugged and almost inaccessiljle places, like the pines in the 

 southern part of the peninsula." 



Page 159. Populus dimorpha. "Alamo," "chopo" (Sinaloa). 



Populus arizonica. The Pima Indians of Arizona formerly ate the fresh catkins 

 of this and related species, stripping off the flowers between the teeth. 



Page. 160. The following names are reported for undetermined species of 

 Salix: "Tocoy" (Huastec, Asiai7i); "hoo-cuy" (Zoque, Gonzales); "xitzo" 

 (Otomf, Buelna). By some of the North American Indians willow bark was 

 smoked like tobacco. The Chiricahua Indians are said to have obtained a 

 yellow dye from the trees, while the Pimas employed the inner bark for making 

 breech clouts and skirts. 



Page 161. y^alix humholdtiana. Tliis and its synonjans should be placed in 

 synonymy under Salix chilensis Mol. (Sagg. Chil. 169. 1782), the oldest name 

 for the species. 



Page 162. Salix taxifolia. "Jaray" (Sinaloa). The branches are used for 

 rough brooms, and the bark as a remedy for malaria. 



JUGLANDACEAE. 



Page 165. Juglans. Buelna reports the Otomf name for walnut (nogal) as 

 "ttzatchu." Walnut bark is said to have been employed by some of the Indians 

 of the United States for poisoning fish. 



Page 166. Hicoria pecan. "Napacoma" {Villada). Villada gives the 

 Nahuatl name as "quauhcacoatl." 



Page 167. After Hicoria pecan insert the following: 



Hicoria diguetii (Dode) Standi. Carya diguetii Dode, Bull. Soc. Bot. France 

 55 : 470. 1908. Described from Mexican specimens. 



BETULACEAE. 



Page 168. Alnus jorullensis. This species occurs also in Sinaloa, where it is 

 called "alizo." At Orizaba it is said to be called "ilite verde." 



Alnus arguta. "Alizo" (Sinaloa). 



Page 169. Carpinus caroliniana. Collected also in Sinaloa. 



Page 171. An elaborate monograph of the American oaks has been pub- 

 lished recently by Trelease (Mem. Nat. Acad. Sci. 20. 1924). In this there are 

 described and illustrated many new species from Mexico.
