NEW Oil NOTEWORTHY SPECIES. 297 



Bat for the firm, spreading and rather persistent sepals, 

 this handsome buttercup, in the absence of mature fruit, 

 would perchance have passed for a rank northern R. Nelsomi^ 

 As it is, there is no described species, to which it can at all 

 be referred; and we are glad to be able to dedicate so fine a 

 new plant to the gentleman who has given the very best of 

 recent contributions to our knowledge of Alaskan vegetation, 

 Mr. J. H. Turner, who brings it from Porcupine Eiver. 



Sambucus maeitima. S. calllcarpa, Greene, Fl. Fr. 342 

 (1892), partly. Arborescent, 10 to 25 feet high, tlie ti-mdv 

 somewhat flaky rather than with close and firm fissured bark: 

 pith of shoots white: young twigs and leaves pubescent with 

 retrorse hairs: young leaves with small ligulate callous-tipped 

 stipules: cymes small, dense, flat- topped ; corolla rotate, 

 white: fruit dark purple with a reddish tinge, slightly 



glaucous. 



Tliough I named as the type of my S. caUioarpa the beau- 

 tiful scarlet-berried elder common in California, and called 

 S. raccmosa in the State Survey B.)tany, the description of 

 the trunk, foliage, etc. was drawn from fresh specimens of a 

 tree which now proves, by its mature fruit, to be a whol y 

 distinct and new species. Said trees, which by their early 

 flowering and general resemblance to the red-berried species, 

 I had always supposed to be that, had always interested me 

 deeply by their strangely maritime habitat. They stand at 

 only a few rods distance from a sand-beach of San Francisco 

 Bay; and that in a depression which can not more than equal 

 the level of the salt water at less than the Ingliest tide. 

 Almost underneath the trees grow great quantities of Poten- 

 tilla Anserina and other plants of brackish marshes, ihis 

 habitat had not failed to impress me ; because the usual 

 locations for the early and red-berried elders nre grounds 

 among the wooded hills, or at least aloT.g the banks of moun 

 tain streams well above the high water mark. S ill it was
