northeast of the town, from a small mountain lake or pond, runs through) a narrow, chasm-like 
valley, which widens about three miles from Santa Fé, and opens into the plain just where the 
town is built. Below, the water of the creek is almost entirely absorbed’ by the numerous irri- 
gating ditches, which are most essential for the fertilization of the else sterile fields. Most of the 
characteristic plants of the upper part of the creek and of the mountain-sides are those of the 
Rocky Mountains, or of allied forms; some of which, such as Atragene Ochotensis or alpina, 
Draba aurea, &c., have never before been met with in so low a latitude (under 36°). 
‘Mr. Fendler made his principal collections from the beginning of April to the beginning of 
August, 1847, in the region just described. At that time, unforeseen obstacles obliged him to 
leave the field of his successful researches. He quitted Santa Fé, August 9th, followed the usual 
road to Fort Leavenworth, which separates from the ‘ Bent’s Fort road’ at the Mora River, and 
unites with it again at the ‘Crossing of the Arkansas.’ The first part of the route from Santa 
Fé to Vegas leads through a mountainous, wooded country, of much botanical interest, crossing 
the water-courses of the Pecos, Ojo de Bernal, and Gallinas. From Vegas the road leads north- 
eastwardly through an open prairie country, occasionally varied with higher hills, as far as the 
Round Mound (6,655 feet high, according to Dr. Wislizenus). The principal water-Courses on 
this part of the route, all of which furnished different remarkable species, were the Mora, Ocaté, 
Colorado (the head of the Canadian), and Rock Creek, all of which empty into the Canadian. 
Rabbit’s Ear Creek and McNees Creek (the head-waters of the north fork of the Canadian) are east 
of the mountains altogether. From thence the Cimarron was reached, where the Cold Spring, 
Upper, Middle, and Lower Spring, and Sand Creek are interesting localities. On September es 
Mr. Fendlerrecrossed the Ark and reached Port Heaven worth 
UII the 24th Or that month,’ 
Mr. Fendler is about to revisit New Mexico, for a more thorough exploration of the 
botany of that little known region, and especially of the higher mountains in the northern 
and western part of the district. It is greatly to be wished that he should receive pat- 
ronage, in the form of additional subscriptions for his collections, which may enable him 
to reéngage in this arduous undertaking under more favorable circumstances than before. 
Several families of the ensuing ‘enumeration, such as the Cactacee, Cuscutinex, As- 
clepiadee, Euphorbiacez, &c., have been elaborated by Dr. Engelmann, of St. Louis, 
upon whom a lafge share of the labor and care incident to this enterprise has fallen. His * 
name is affixed to the portions, as well as to various notes, thus contributed by him. 
The species of which there were not sufficient specimens collected for distribution 
in the sets are designated by the sign (f) prefixed to the number. Vide No. {2 et seq.
