In these specimens the ripe siliques are 7 cm. long and about 

 3 mm. broad, and spread either horizontally or upwardly. The 

 stems are generally several from a perennial root and are conspic- 

 uously clothed with the sheathing petioles of former leaves for 

 about two inches below the ground. The new shoots for the 

 flowering stems of the next year are almost always present and 

 have spatulate leaves with small blades, about 1 cm. long, and 

 almost filiform petioles 2-5 cm. long. The flowers are 2 cm. or 

 more across. The seeds are 1-6 mm. in diameter, narrowly 

 winged but not continuously, and have accumbent cotyledons. 

 The short style of the silique is evident and forms a beak. 



The form common in the vicinity of San Francisco was origin- 

 ally described in Linnaea I. 14, by Chamisso and Schlechtendal. 

 The transcript of the original description follows : 

 "Cheiranthus aspcr. Nob. 



Ch. foliis sinuato-dentatis, inferioribus lanceolatis, superioribus 

 sublinearibus, pube bipartita, caulibus basi adscendentibus erectis, 

 siliquis pedicello triplo longioribus stylo brevi apiculatis." * 

 * * "In littore Californiae." 



"Habitus florentis plantas est species omnis Erysimi lanceolati 

 cuius varietatum esse crederes. Tota planta paullo magis scabra, 

 folia radicalia et caulina remote sinuato-dentata, dentibus acutis. 

 Caulis sesquipedalis basi adscendens, simplex aut ramosus, fere 

 semper atque ex omnibus axillis foliorum fasciculos s. ramos 

 abbreviates steriles prodens. Pedunculi quam in Er. lanceolato 

 paullo longiores circiter 6 lineares. Siliquae paucae maturge in 

 nostris speciminibus, circiter 15 lin. longa\ lineam lake, coni- 

 pressx' ; plurimis ovulis abortu baud perfectis, pauca modo ader- 

 ant semina in quoque loculo ; valvuhe medio uervo extus promi- 

 ueute a basi ad apicem sunt uotatie. Stylus siliquam terminans 

 brevis vix semilinearis, crassus, stigmate capitato, indistincte 

 bilobo. Semen lineam longum compressum, cotyledones accum- 

 bentes." 



This species was identified by Hooker from specimens sent to 

 him by Chamisso with a species collected by Douglas " on rocky 

 places of the Columbia, near the sea and at Puget Sound," 

 Hook. Fl. Bor. Am. I. p. 38.
