Arabis, sp. — San Ignacio. 

 Sisymbrium reflexum Nutt. — San Gregorio. 

 Sisymbrium canescens Nutfc. —San Gregorio. 

 Thelypodium, sp. — Magdalena Island. 

 Nasturtium tanacetifolium (Wall.) ? — Purisima. 



Nasturtium (?) laxum Watson. Evidently the same plant, 

 but the segments of the lower leaves are more numerous 

 than described. The immature pods are more than 12 ram. 

 in length, slightly 4 -angled, valves 1 -nerved, cotyledons 

 incumbent, seeds in one row, 10 to 12 in each cell. — San 

 Gregorio. 



Nasturtium curvisiliqua Nutt. var. lyratum Watson.— 

 San Ignacio. 



Lyrocarpa Xanti, (Plate II). Annual, branching near the 

 base: stems decumbent, a foot or two long: leaves, sepals 

 and ovary somewhat pubescent, with branching hairs: 

 leaves all petioled, cordate-lyrate, repand, 2-4 inches long, 

 1-2 inches wide: flowers in an elongated leafless raceme, 

 dark purple: petals obovate-lanceolate, 9 lines long: pods 

 nearly an inch in length, not constricted above, cells 5-10 

 seeded; seeds wingless. 



This is probably the plant mentioned in Bot. Cal. 44 

 and Proc. Am. Acad. Y, 153. The bright colored, hand- 

 some flowers and habit of growing in masses make it one of 

 the most showy annuals of the region. The seeds difl*er 

 from the generic description in being wingless. — San Gre- 

 gorio and Santa Margarita Island. 



Lyrocarpa Coulteri Hook. & Harv. Suffrutescent, much 

 branched from the base and perennial. — San Gregorio and
