icoscordion venenosum (Wats.) Rydb., a rather large flowered 

 plant, the original of which came from wet places in the middle 

 coast region of California. This species probably does not occur 

 outside of California, but Watson mixed one or more other spe- 

 cies with it, and confusion as to the identity of the plant has 

 existed from the very beginning. The other known species 

 and their ranges are: 



T. intermedium Rydb. the type of the genus, has been found 

 in Idaho, Montana, Wyoming and Utah: T. gramineum Rydb. 

 from Saskatchewan to Idaho, Montana, Wyoming and South 

 Dakota; T. acutum Rydb. South Dakota; T. falcalum Rydb. 

 Colorado; T. Nuttallii (Gray) Rydb. Arkansas ana Kansas; T. 

 Fremontii (Torr.) Rydb. coast region of middle California; T. 

 arenicola Heller, Inyo county, California, and probably north- 

 ward into western Nevada. 



J. J. Sullivan, M. D., a member of the Board of Regents of 

 the University of Nevada, while a student at the University, 

 prepared a manuscript on certain poison plants, from which the 

 following is extracted: 



"Wild onion (Zygaacnus pauiculatus) belongs to the lily 

 family, and has received the common names 'wild sego,' 'sand 

 corn," etc. The following description of the plant is from a 

 newspaper bulletin published by Professor Hillman in May, 

 1893: 'The various species of the genus Zygadcnus are mainly 

 western in their distribution, and range from the southern to the 

 northern limits of the country, and westward to the Pacific. 

 One particular species seems to have a more limited distribution, 

 being confined to parts of Nevada, California and Utah. The 

 plant is most common in the foothill regions, but sometimes oc- 

 curs on the wild lands in the vicinity of the hills. Both the 

 hard and rocky and sandy soils seem favorable to the plant's ex- 

 istence. Popularly described, the plant is deep rooted, bearing 

 a coated bulb six or more inches below the surface of the ground. 

 Below the bulb is a blackened stem which has sent forth plants 

 in previous years. This is but a half inch or more in length 

 and diameter, and produces from its crown a few living roots. 

 Along its side numerous dead roots occur. The plant appears
