valley, which, being a new generic type in a favorite order, may 



most appropriately and deservedly bear Mr. Bolander's name and 



commemorate his services to our science. In applying this name to 



species, as I have occasion largely to do, I have reluctantly followed 



the example set for me by Mr. Lesquereux and Professor Tuckerman, 



in writing " Bolanderi " ; yet for the genus (notwithstanding the name 



is doubtless Scandinavian) I prefer the form consecrated by unbroken 



usage in the strictly similar case of Solander (also of Dryander, if that 



is not a genuine Greek-made name), and here write Bolandra rather 



than Bolandera. 



Sedum obtusatuii : glabrum, subglaucum ; foliis planis spathulatis 



cuneatisve, summis oblongis ; floribus laxe cymosis pedicellatis 5- 



rneris ; petalis ovali-oblongis " flavidis " sepala ovata longius super- 



antibus, utrisque obtusissimis ; seminibus appendice cultriformi termi- 



natis. — Granite rocks in the Sierra Nevada, on Mount Hoffman and 



above Sonora Pass, Brewer ; at Vernal Fall in the Yosemite Valley, 



Bolander. Habit and aspect of S. spathuli folium and S. Oreganum ; 



but the flowers larger than in the former, all pedicellate, and petals 



paler, in the specimens mostly seeming to have been almost white. 



DEWEYA, Torr. & Gray, Fl. N. Am. 1, p. 641. This genus, 

 which Bentham and Hooker have recently, with Velcea, reduced to 

 Arracacia, may be sustained upon the undivided carpophore and the 

 total want of stylopodia ; perhaps also on the completely involute seed. 

 There is, indeed, no decisive evidence as to the carpophore in the 

 original species, of which fully ripe fruit has not yet been examined, 

 but it remains quite entire after the fall of the carpels in the two 

 species now added. It is to be noted, however, that Bentham, in PI. 

 Hartw. p. 187, describes Arracacia glaucescens as having "carpopho- 

 rum vix apice bifidum " ; but this is passed over in the Genera Plan- 

 tarum, where much is made of the carpophore in this tribe. 



Deweta arguta, Torr. & Gray, 1. c. ; Torr. in Bot. Mex. Bound, 

 t. 26. — Folia simpliciter pinnata. Calycis dentes subulati persis- 

 tentes. Fructus oblongus, jugis subalato-elevatis. 



Deweta Hartwegi : fere acaulis, secus petiolos venas venulasque 

 foliorum scabrella; foliis biternatis et quinatis ; foliolis obovatis seu 

 ovali-oblongis quam D. argutce minus argutis magisque confluentibus ; 

 calycis dentibus obsoletis ; fructus paululum brevioris jugis carinato- 

 elevatis vix alajformibus. — On the Sacramento, Hartw eg, No. 1748, 

 in flower. Near San Francisco, Dr. A. Kellogg, in fruit. A leaf
