Note 223 — INTRODUCTION.
Reading edition
The Navahoes say they are acquainted with four kinds of wild tobacco, and use them in their rites. Of these the author has seen and identified but two. These are Nicotiana attenuata which is the dsĭ′lnạto, or mountain tobacco; and Nicotiana palmeri, which is the depénạto, or sheep tobacco. N. attenuata grows widely but not abundantly in the mountains of New Mexico and Arizona. N. palmeri is rare; the writer has seen it growing only in one spot in the Chelly Canyon. It has not been learned what species are called weasel tobacco and cloud tobacco; but one or more of the three species, N. rustica, N. quadrivalvis, and N. trigonophylla, are probably known to the Navahoes.
