While some Palms, as indicated, descend to cooler latitudes, 
others ascend to temperate and even cold mountain regions. 
Among the American species are prominent in this respect : 
Euterpe anclicola, Brogn., E. Haenlceana, Brogn., E. longi- 
vaqincda, Mart., EiplotJiemium Porallyi, Mart, and Ceroxylon 
pithyropliyUum, M-a.vt., all occurring on the Bolivian Andes 
at an elevation of about 8000 feet. — Ceroxylon andioola, 
Humb., KuntMa montana, Humb., Oreodoxa frigida, Humb., 
and Geonoma densa, Linden, reach also on the Andes of 
New Grranada a height of at least 8000 feet. — Ceroxylon 
Klopstochia, Mart., advances on the Andes of Venezeula to 
a zone 7500 feet altitude, where Karsten saw stems 200 feet 
high with leaves 24 feet long ! There also occur liyagrus 
Sancona, Karst, and Platenia Gliiragua, Karst, at elevations 
of 5000 feet, both very lofty Palms. Prom the temperate 
mountain regions of sub-tropical Mexico are known among 
others ; Gliamaedora concolor, Mart., Copernicia Pumos, 
Humb., G. nana, Kunth, and Braliea dulcis, Mart., at eleva- 
tions from 7000 feet to 8000 feet. 
Xanthorrhiza apiifolia, I’Herit. 
North America. A perennial almost shrubby plant of 
medicinal value. The root produces a yellow pigment, 
similar to that of Hydrastis Canadensis, L. Both contain 
also Berberin. 
Ximenia Americana, L. 
Tropical Asia, Africa and America, passing however the 
tropics in Queensland, and gaining also an indigenous 
position in Florida. This bush may therefore accom- 
modate itself to our clime in localities free of frost. 
The fruits are edible, resembling yellow plums in ap- 
pearance ; their taste is agreeable. The wood is scented. 
Yucca filamcntosa, P- 
The Adam’s Needle. Prom Carolina and Florida to Texas 
and Mexico. An almost stemless species. It would hardly 
be right, to omit here the plants of this genus altogether, as
