easy to understand, therefore, the difficulties in the 
way of preparing a correct list of the species of Col¬ 
orado plants. The writer of these notes has spent 
considerable time conferring with various authori¬ 
ties for the purpose of making the list as nearly cor¬ 
rect as possible. We follow mainly the nomenclature 
of the Cyclopedia of American Horticulture, quot¬ 
ing in each case the specific authority so that any 
one may adopt the synomyn preferred. 
The following notes will explain some of the 
changes which it has seemed advisable to make from 
our former lists, and other questions in this relation: 
Aconitum Columbianum of the Colorado Moun¬ 
tains seems to be quite distinct from A. Fischeri 
Wats, though considered the same by some authori¬ 
ties. 
Aquilegia Coeruiea; our seed is saved from 
wild plants in the mountains and is positively true. 
Astragalus Prumfer; formerly included with 
A. caryocarpus. 
Delphinium albescens* — D. azureum albidum. 
Delphinium Geyeri — D. Scopulorum of Coul¬ 
ter’s Manual in part. 
Machaeranthera; a group of very handsome 
large flowered plants formerly included with Aster. 
Mertensia ciliata (Torr.)—M. Siberica of Coul¬ 
ter's Manual, not Don.; distinct from the European 
plant. 
Oenothera caespitosa; two forms are included 
here, ours is the very large flowered, perennial, acaul- 
escent form. 
Oenothera Goodingii; Coulter’s O. brachycarpa 
includes two distinct forms, of which the plants o f ( 
the Colorado foot hills having flowers and fruit 
much larger than the type has recently been given 
the name as above. , 
Pentstemon Glaber, this is a tall plant, 2 to 3 
feet, apparently different from one offered by the 
same name in Europe. 
Polemonium moiie —P. fcliosissimum of Coul¬ 
ter. 
Berber is repens; distinct from B. aquifolium 
of dealers. 
Ribes tenuiflorum; related to aureum but with 
large yellow or cherry tinted fruit; very handsome. 
Rosa Woods'! i— R. Fendleri of Coulter’s Man 
ual in part.
