NOTES FROM NORTHERN UTAH— I 

 By C. P. Smith 



Trifolium gymnocarpon Nutt. While in Parley's Park 

 last summer, I picked up a few scraps of this plant, long past 

 the flowering stage. Upon examination, soon after, the leaflets 

 were found to number four and five, as a rule, and I landed 

 nowhere in my attempt to determine the species, supposing 

 number of leaflets to be of some importance. Even Watson, 

 who reports it from this same locality (sagebrush foothills, Par- 

 ley's Park) and illustrates it, gives no suggestion of more than 

 three leaflets. Nor do I find reference to four or five leaflets in 

 this species in any of the literature at hand. 



Sida hederacea (Dougl.) Torr. This species has received 

 my attention, wherever I have met it, because of its apparent 

 lack of frequency in the ripening of its seeds. It is common in 

 the town of Mayfield, College Terrace addition, California, and 

 appears as if native amongst the foothills westward, but many 

 efforts to obtain seed of it there met with no success. It is com- 

 mon along the Southern Pacific railroad near Castroville, Cali- 

 fornia, on the main line to Salinas, where it flowered profusely 

 during the season of my observation; but again my search for 

 seed was not rewarded. 



In Utah I have found it well established along the Southern 

 Pacific, out of Ogden three miles, and along the Oregon Short 

 Line, about midway across the valley between Mendon and Lo- 

 gan, Cache county. Along these railroads it certainly appears 

 as if introduced. Last September, however, I at last secured a 

 few seeds, from the locality last mentioned, and think I can say 

 that I obtained not over one seed for each fifty heads of carpels 

 examined — certainlv not a very high rate of productivity.
