Li. W^ardii, Watson. Caudex simple ; the short stems procumbent : radical leaves round- 

 ovate on slender petioles ; the cauline short, linear to obovate-subulate : petals 3 lines long, 

 ligular-spatulate : filaments linear-subulate : pods on short pedicels (2 or 3 lines long), 1| to

 petals 4 lines long with a very broad undulate claw, somewhat contracted below the rounded 

 blade: pedicels longer : ovary obcompressed ; the cells 12-ovuled (mature pod unknown). — 

 Arizona, Palmer. Like the last abnormal in its obcompressed pods and perhaps to be

 caudex ; the simple stems a foot long or more : lower leaves narrowly oblanceolate, repand ; 

 the cauline linear-oblanceolate, entire or sparingly toothed : petals spatulate, 3 lines long : 

 pods ovate-globose to broadly ellipsoidal, erect on spreading or ascending pedicels, 2^ to

 mostly narrowly oblanceolate to linear ; the radical frequently sparingly toothed : petals 

 spatulate, 3 or 4 lines long: pods more or less pendulous upon recurved pedicels, 1^ to 2^
