Mountain in the Eastern Sierra Nevada, Dr. C. L. Anderson, 1866. 

 The allied R. Chamissonis has the achenia winged, as much as R. 

 glacialis. 



Ranunculus (Aphanostemma) hystriculus: glaber; radice fas- 

 ciculata; foliis omnibus radicalibus reniformi-rotundatis 5-lobis crenato- 

 lobulatisque ; scapis folia superantibus nudis unifloris rariusve unifoli- 

 atis bifloris ; sepalis (5 - 6) petaloideis albis ovalibus ; petalis totidem 

 staminibus brevioribus nectariformibus, ungue longo lamina parva ovali 

 subcarnosa basi foveolata terminato; carpellis lanceolatis tenuiter mem- 

 branaceis pilosciusculis stylo subrecurvo rostratis in capitulum subglo- 

 bosum hystricinum arete digestis. — Foot-hills of the Sierra Nevada, 

 at Forest Hill and at New Castle, Placer Co., April, 1865, Bolander. 

 Also, 1866, by Mr. Rattan, a state with longer petioles (6 inches long), 

 and scapes nearly a foot high : apparently in wet soil. Sepals nearly 

 half an inch long, deciduous. Petals inconspicuous, 1£ to 2 lines long, 

 apparently yellow, gland-like, consisting of a minute fleshy lamina, 

 with its base impressed with a nectariferous pit, raised on a claw of 

 twice its length. Carpels 3 lines long when nearly full grown, re- 

 markably slender and tapering, not striate nor margined. Ovule 

 ascending as in Ranunculus. — Nothing like this has before been met 

 with ; but the characters, as to calyx and corolla, are those of St. 

 Hilaire's Aphanostemma, although the subulate carpels very different ; 

 so that this accession, remarkable as it is, hardly tends toward the 

 re-establishment of that genus. 



Aquilegia Californica, Lindl. in Gard. Chron. 1854, p. 836, & 

 1857, p. 382. A. eximia, Van Houtte, Fl. des Serres, Jan. 1857, 

 cum ic. This is common in California (is Hartweg's, no. 1635), and 

 comes also from Oregon. In cultivation the characters do appear to 

 be well marked. That is, the sepals are reflexed ; the spurs, scarcely 

 longer than the sepals, are much thickened at the tip, and truncate at 

 the mouth, the limb of the petals being extremely short. But Fisch- 

 er's A. formosa is intermediate between this and A. Canadensis in the 

 relative length of the spurs and sepals, the latter widely spreading. 

 In cultivation A. Californica comes into flower a month later than A. 

 Canadensis. 



Draba Douglasii : Leucodraba ; caudice multicipiti ; foliis omni- 

 bus rosulatis subcartilagineis fere eveniis integerrimis margine crebre 

 hispido-ciliatis facie aut glabris aut cum scapo aphyllo corymboso- 

 plurifloro hirsutulis (pilis omnibus simplicibus), imis ovatis, superiori-
