OF ARTS AND SCIENCES: JUNE 11, 1867. 835 



(ut videtur) saturate caerulea, carina nuda. — Summit of the Cascade 

 Mountains, lat. 49°, Dr. Lyall (Coll. Oregon Bound. Comm., distrib. 

 Herb. Kew.). — The short, tufted shoots spring from a woody base 

 barely an inch high, terminated by the solitary naked peduncle, bearing 

 a head (half or two thirds of an inch in diameter) of deep blue or violet 

 flowers. Pedicels short : bracts shorter than the calyx, caducous. 



LuPiNUS Danaus : herbaceu?, e caudice perenni csespitosus, pu- 

 milus, strigoso-hirsutulus ; stipulis subulatis ; foliolis 4-5 oblanceo- 

 latis (lin. 2-4 longis) •, racemo oblongo (pollicari) densifloro ; calycis 

 minute bracteolati labio inferiore tridentato, superiore profunde bifido ; 

 corolla albo-violacea, carina rectiuscula ciliata. — Mount Dana, alt. 

 about 12,500 feet, Bolander. — This interesting little Lupine maybe 

 held to bear the name either of the lofty peak it inhabits, or of the 

 distinguished geologist and naturalist whom the mountain commemo- 

 rates. It was very scantily collected, and is probably rare or out of 

 reach. The slender and diffuse or ascending flowering stems are only 2 

 or 3 inches high, and 1 — 3-leaved below the middle. Bracts subulate, 

 rather shorter than the calyx, twice the length of the pedicel. Co- 

 rolla 3 lines long ; the vexillum and wings apparently white and tinged 

 with blue or violet, the keel deep violet. — This and the two preceding 

 seem very distinct from all other North American species. Neither of 

 them can well be L. minimus, Dough, which I do not identify. 



Trifolium Bolanderi : T. repenti subsimile, multiceps e caudice 

 incrassato, glaberrimum ; caulibus adsurgentibus 1 - 2-floris ; stipulis 

 herbaceis ; foliolis obovato-oblongis vix retusis ; pedunculis (spitha- 

 mjeis) folia longe superantibus ; floribus (coerulescentibus ?) arete capi- 

 tatis mox deflexis ; pedicellis etiam fructiferis brevissimis ; calycis 

 dentibus subulatis tubo campanulato basi gibboso subajquilongis ; ovario 

 dispermo. — Westfall's Meadows above the Yosemite Valley, at the 

 elevation of 8,000 feet, Bolander. 



Trifolium barbigerum (Torr. Bot. WhippL Exped.), var. An- 

 DREWSii : multo majus, subpedale, villosum ; foliolis majoribus sub- 

 pollicaribus ; involucre explanato quandoque fere pollicem lato (corollis 

 atropurpureis). — Collected by the late Dr. Andrews in 1856; but 

 now Mr. Bolander sends it from Mendocino City (4781), with heads 

 &c. fully as large as those of the related T. cyathiferum, and also, 

 from drier and sandy soil (4755), in a form like the original of Bige- 

 low and Fitch, but less depauperate.
