ACCSSSIONS TO APOCYNUM. 183 



largest ^. androsaemifolium, but with smaller and quite reddish 

 flowers. It has an almost coriaceously thick foliage, and is 

 of the arid interior of the county. 



Apocynum stbnoIvOBUM. Plants branched from almost the 

 very base, only 6 to 10 inches high, glabrous throughout: 

 lowest leaves small, oval obtuse, }i to }i inch long, the others 

 exactly ovate, lj4 inches long, obtuse at base, scarcely acute 

 at apex though there very prominently subulate-mucronate, 

 of thinnish texture, very dark-green above, whitish with 

 bloom beneath, the upper ascending on rather long and slen- 

 der petioles, the lower widely spreading or even deflexed : 

 flowers few and large, mostly terminal; sepals triangular- 

 lanceolate, with long and slender acumination ; corolla with 

 long narrow cylindric tube and very long oblong-linear sub- 

 erect segments, the whole little less than j4 inch long, pinkish 

 or flesh-color. 



This is another of the fine discoveries of Mrs. R. M. Aus- 

 tin in extreme northwestern California, where she obtained 

 it, on Davis Creek, Modoc Co., in 1895. It can have formed 

 no part of the Grayian var. pumilum, for that author never 

 saw this plant. The type sheet is in my own herbarium, 

 n. 7052. 



Apocynum panicui,atum. Plant a foot high more or less, 

 with short naked main stem erect, but the branching above 

 this wide and somewhat fastigiate, the branches copiously 

 leafy, all of them at summit very definitely cymose-panicu- 

 late : leaves about 13^ inches long, 1 inch wide, mostly of 

 precisely ovate outline, but many oval, very short-petioled, 

 at base subcordate, at apex obtuse or only acutish, of rather 

 firm texture, dark-green above, glaucous beneath, spreading 

 apart, but not drooping ; numerous flowers borne above all 

 foliage in about 5 to 7 simple or compound cymes of which 

 the terminal one is not larger than the laterals which join it 

 to form an apparently panicled inflorescence : sepals triangu- 

 lar-lanceolate, acute, the tips straight ; corolla with long tube
