THE KOSES OF PECOS, NEW MEXICO. 



BY T. D. A. COCKERELL. 



Pecos, New Mexico, is on the upper Pecos river, about 6,800 feet 

 above sea level and no A^ery great distance from Santa Fe. It has 

 essentially the flora made familiar to botanists everywhere by the 

 collections of Fendler and Heller, the cafion a few miles above the 

 village furnishing Galpinsia fendleri (Gray), Cerens triglochidiatus En- 

 gelm., Sphceralcea fendleri Gray, Viola neomexicana Greene, Berberis 

 fendleri Gray, Linum aiistrale Heller, L. puherulum (Engelm.), Ver- 

 bena macdougali Heller, Philadelphus microphyllus Gray (the flowers 

 of which have an odor like that of spoiled oranges), Salix irrorata 

 Anders., Sidalcea neomexicana Gray, etc., etc. The bottom land 

 through which the Pecos river flows is thickly wooded for a few miles 

 on the Kin Kale Ranch, the trees being Popidus angusUfolia James, 

 with a mixture of willows, Alnus tenuifolia Nuttall, and on the out- 

 skirts Quercus novomexicana (A.DC), Q. leptophylla Rydberg (new to 

 New Mexico), etc. Under the shade of the trees it is cool and moist, 

 so that members of the Canadian zone flora are able to grow, while a 

 fcAv hundred yards away the dry bluffs possess a typically austral and 

 xerophytic assemblage of plants. As a result of these conditions the 

 locality, taken as a whole, is remarkably rich in species of both plants 

 and animals. The roads and cultivated fields are skirted by oak- 

 bushes, including the peculiar Quercus havardi Rydberg, only known 

 previously from Texas. Roses are abundant, and a few species of 

 climbing plants {Clematis ligusticifolia Nutt., Humulus lupidus neo- 

 mexicanus Nelson and CklL, Parthenocissus quinquefolia (L.) Planch) 

 are very conspicuous. The common weeds include Grindelia inorrmta 

 Greene, Lathyrus decaphyllus Pursh, Argentinia anserina (L.), Vicia 

 americana Muhl., Salsola tragus L., Anogra coronopifoUa (T. and G.), 

 Verbascum thapsus L., Erodium cicutarium (L.), Physalis pubescens L., 

 Allionia viscida {Oxybaphus angustifolius var. viscidus Eastwood, Pr. 

 Cal. Ac. Sci., 1896, p. 313), Solanum jamesii Torrey, Helianthus petio- 

 laris Nutt., H . annuus L., etc. Quite a surprise was the discovery of 

 a -large quantity of Chrysanthemum leucanthemum in a field on the Kin 

 Kale Ranch, this plant being hitherto unknown in New Mexico. The 

 austral Solanum ekeagnifolium was seen growing near Harrison's Store,
