ZUNl AND COLORADO RIVERS. 175 



NOTE. 



The botanical collections placed in my hands for examination by Dr. Wood- 

 house, consisted of three portions. The first were made chiefly between the 

 Neosho and Arkansas rivers, and on the North Fork of the Canadian. The flora 

 of this region embraces a great many plants of the States east of the Mississippi, 

 and although a full catalogue of the species was prepared, it was not considered 

 as of sufficient value to publish it. Some of the more interesting plants found 

 i*?tween the Neosho and the Arkansas are Hypericum Drummondi, Talinum 

 aurantiacum, (Enothera rhomMpetala, Discopleura Nuttattii, Eryngium Leaven- 

 worthii, Heliotrojnum, tenellum, Torr., (Lithospermum tenellwm, Nutt.) and Frctli- 

 chia Floridana. 



Of those found on the North Fork of the Canadian, the following are the more 

 important: Cleomella angustifolia, Dithyraa Wislizeni, Hosackia Purshiana, Rosa 

 foliolosa, (Enothera Jamesii, Mentzelia omnia, Eryngium diffusam, Heterotheca 

 scabra, Cosmidiwm JUifolium, Coreopsis aristosa, RudbecMa itlismafolia, SoMago 

 Missourierisis and peliolaris, Jlmphiachyrsis dracunculoides, Vernonia Jirkansana, 

 Echinacea angustifolia, Cenlaurea \3mericana, Lobelia Texensis, Giliu longifiora, 

 Euploca convolvulacea, Sabbatea campestris, Ipomma IcptophyUa, Jlsclepias speciosa, 

 Eustenia albida, Hendecandra Texensis, Euphorbia armaria, Eriogonium annuum 

 and longifoliuin, and Yucca angustifolia. 



The Texan collection was much richer, and a catalogue of it was also prepared, 

 but omitted at the suggestion of Dr. Woodhouse, as Mr. Wright, and the botanists 

 of the Mexican Boundary Commission, had so recently explored the route passed 

 over by Captain Sitgreaves. Most of the plants in this part of the collection 

 were gathered between San Antonio and El Paso del Norte. There are very few 

 of them that are not included in Dr. Gray's Plantse Wrightianse, as far as that 

 work is published. Beyond Composite, the following are the principal : Specu- 

 laria ovala, (Dysmicodon ovahm, Nutt.,) Camptjlocera leptocarpa, Nutt., Chilop- 

 sk linearis, Stetlandrium barbatuin, Gray, Galophanes linearis, I.eucophyllum Tex- 

 anum, Pentstemon dasyphyllum, Cobaea and Grahaini, Solawum Texanum, Ery- 

 thrcsa Beyrichii, HeUotrophum inundatum, and Greggi, Torr. mss., Salvia 

 enth., Jlsclepias longicorhis, Tetraclea Wrightii, Gray, Acleisanthes 

 longiflora, Gray, Querats Emoryi, Juglans rupestris, /2 :' t}reenia m .Vrkansana; 

 Nutt., Chcilanthcs gracilis, and Selaginella convoluta, Spring. 



The third collection was made between El Paso and California, in the latter 

 part of the summer and autumn of 1851. Most of the plants were found on 

 the route from Laguna to the Puebla of Zuiii, a tributary of the Colorado of the 

 West. The Zuni mountains (Sierra de Zuiii) rise to the height of 7,545 feet. 

 When the party reached California, it was so late in the season that very few 

 plants were in a proper state for the herbarium, and the collection is accordingly 

 meagre in specimens from the western extremity of the route. It is hoped that 

 the list here given will at least contribute to our knowledge of the botanical 

 geography of our far western territories.
