 them exactly agrees with Dr. Gray's description of that species.

Notes on Colorado Plants. — During several seasons of bot- 

 anizing in northern Colorado I have collected several plants which 

 seem to be of some interest as occurring in the state and I note 

 them to add to their geogra})lucal range. Of these may be noted: — 



1. Plants of the Plains. Some of these may have come to Col- 

 orado from the east. Acuan Illinoensis (Mich.) Kuntze and Lacin- 

 aria spicata (L.), Kuntze, are found at Sterling in Logan County, 

 Euphorbia serpens H. B. K., and Tissa marina (L.) Britton, at 

 New Windsor in Weld County, and Heteranthera limosa (Sw.) 

 Willd, on the eastern border of Larimer County. 



2. Plants of the Foot-hills. These are found at an altitude of 

 5,000 to 7,000 feet, and are indigenous. Smilax herbacea L., and 

 Osmorrhiza longistylis D. C, grow along streams on the eastern 

 side of the mountains in Larimer County, Helianthemum majus 

 B. S. P., at Palmer Lake, on the divide between Denver and Col- 

 orado Springs, and Solidago speciosa Nutt., in the mountains of 

 Larimer County, at about 7,000 feet altitude. This I have col- 

 lected only once. Here, too, may be placed Astragalus artipes A. 

 Gray, collected at Glen wood Springs, on the western slope. So far 

 as I know it has been reported only from Arizona and Utah. 



3. Plants of the Mountains. Some of these are northern species 

 which come to Colorado along the high mountain -range. Mimulus 

 Lewisii Pursh is found in the high mountains west of North Park. 

 About North Park are also found Ranunculus tenellus Nutt. (R. 

 Bongardii Greene), and Angelica pinnata Watson. Astragalus 

 Purshii Dougl. grows on some of the hilis, and Astragalus debilis, 

 (Nutt.) A. Gray, along the North Platte. In the synopsis of the 

 genus by Dr. Sereuo Watson, in the " Botany of King's Expedition," 

 the location of this is given as " Plains of the Rocky Mts. along 

 streams (Nuttall)." Ranunculus acriformis A. Gray, which seems
