110 A Botanical Tramp. [ ZOE. 
Linum Lewisii, which gives promise some day of being of consid- 
erable commercial value. 
Negundo aceroides grows luxuriantly all over this region and is a 
favorite tree for front yards in the city of Helena. 
Rhus aromatica var. trilobata was found growing up little gullies, 
but had just gone out of bloom. 
Thermopsis rhombifolia and montana were not found on this trip: 
or region; but the writer knows that they were both in bloom at 
this time on regions but little remote from the range of the trip. 
Lupinus leucophyllus surprised us by showing its blue racemes. 
much earlier than was expected. 
Astragalus caryocarpus was found both in bloom and in fruit, its — 
large globular juicy pods giving promise of service as food for 
man: it is reported from some sections as used for pickles. 
Astragalus Canadensis was only in bud; as also A. adsurgens, 
hypoglottis, and Drummondii. 
Astragalus Missouriensis is very common on our plains, and al- 
ways attracts the botanical eye both for its beauty of bloom and 
grace of pods. It clings close to the soil in its struggle for exis- 
tence on our hot waterless plains. 
Astragalus Purshii was abundant in fruit, but its bloom had gone.. 
The bloom is very scant, yellow; but the pods are turgid and cov- 
ered with glossy white long wool, giving them a very strange ap- 
pearance as they lie flat upon the ground. 
Astragalus triphyllus is also to be found on these gulch sides, 
but at this season out of bloom. One strange experience belongs to: 
the writer, namely: while he has seen this plant by the thousands 
in bloom, he has never yet gathered it in fruit. Many a time has 
he bent down to search for its fruit, but thus far in vain. 
Astragalus inflexus was seen, but not in bloom. Astragalus 
bisulcatus and flexuosus were just beginning to open. 
Oxytropis lagopus was in full bloom, as also O. Lamberti, our 
dreaded “loco weed.” Besides these the writer knows to be in 
bloom at this time in other regions of the State Oxytropts nana, and 
nearly ready to bloom O. deflexa and splendens. . 
ffedysarum boreale is also in bloom, but our specimens instead of 
being purple, as says Coulter’s description, are invariably creamy 
white. Later, the writer finds this growing plentifully at an eleva- 
tion of 8, 300 feet.
