our books e\cci)l r.;iilcy\s luicv oK.i.L(lia of I lorlicullim-. S" tat- 

 as known to me, it is confined lo a hil of j^nound, uncultivated 

 in 19U), near tlie ve<4ctai)lc o;arden on the Ao^ricnltural Colle^re 

 farm, Logan. Probably over fifty plants were present, tlio none 

 were noticed there in 1909. Conditions for its spreadino^ are 

 not very favorable, and it may not even hold its own there very 

 long. Many plants were cut down, with other weeds during the 

 summer, but a few were allowed to .^o to seed. It is the "ro- 

 quette" of European gardens, and uiuloubtcdlv an escape from 

 the college garden. The luad gardener claims that "a garden 

 mustard" was planted years ago, but he has no records of what 

 it was. His a.ssistant says that none such has been planted 

 within the last six years. 



The flowers of this plant resemble very much those of 

 Raphatins salhits as commonly growing about San I'-rancisco 

 bay, California, the whitish petals soon changing to yellow, usu- 

 ally purple veined. The plant in fruit, at least at some distance, 

 resembles -onuwhat Cakilc caUfoniica Heller; but the technical 

 characters agree with none of the genera recognized in our North 

 American manuals, the two rows of seeds in each valve running 

 it \\\^o Diplolaxis, and the large, flat, sword-shaped beak making 

 one want to associate it with Siiiapis alba. 



I^ATHYRUS LATIFOLIUS L. The perennial pea of our .seed 

 catalogs and gardens is frequent in yards in Logan, readily per- 

 sisting without attention, but apparently not escaping much to 

 the wavsides, probably because its need of more moisture than 

 such jjlaces afford in this arid country. I gathered one speci- 

 men from a |)lant growing along an old irrigation gutter outside 

 of a neglected but irrigated yard, where the species was a prom- 

 inent resident. I nicnticni it only in comparison with the next. 



LATiivurs .svi.vKSTRi.s L. Another perennial jx-a of the 

 grou[) with two leaflets is seemingly well established along an 

 irrigation diicli on the Agricultural College farm, tho I did not 

 see it there in 1909. The plants along the main ditch were 

 mowed oxer and it did not seed; but a few s))ecinicns that got 

 into some bushes to one side ripev.ed and scattered many seeds.
