Erysimum linifolium (Nutt. T. & G., Fl. i, 91). 



Sisymbrium linifolium Nutt. 1. c. 



No. 5485. June 23, Castle Gate, Utah, 6000° alt., in 

 gravel, along the river in open places in the juniper belt. 



No. 5486b. Same locality as above. 



No. 5309. May 28, Tropic, Utah, 6000° alt., in fields, 

 in gravel. 



It has always seemed to me that this species is wrongly 

 referred to Sisymhrimn and more properly belongs to 

 Erysimum. It is near to E . cheiranthoides, but verging 

 toward E . asperum. 

 Erysimum asperum var. parviflorum (Nutt. T. & G., 



Fl. 1,95). 



This is certainly only a variety of E. asperum. as given

Erysimum asferum var. ^umilum Watson, Bot. King's 

 Exp. is nothing but typical E . asperum as it is found on 

 the Great Plateau; his specimen is biennial and not per- 

 ennial. 



Erysimum -pumilum var. -perenne Watson, Coville, 

 Death Valley Rep. is not surely perennial, but seems to 

 be an ordinary form of the type with orange flowers near- 

 est to the var. Arkansanum. 



Thelypodium Wrightii var. tenellum. 



No. 5559- Provo, Utah, in Slate Canon, on rocks,. 

 July 2, 1895, 6000° alt. 



No. 53o8ah. Marysvale, Utah, in gravel, 6000° alt., 

 June 4, 1895. 



Many stemmed from a perennial root, stem slender, in- 

 tricately branching above, 2-3° high, retrorsely hispid 

 below; stem leaves all entire or faintly sinuate toothed, 

 thin and delicate, 15^-3' long, lanceolate, obtuse, cuneate 

 at base; pods 2' long, almost filiform, knotty, with long
