Stamens 15, one before each true calyx-lobe, and two before each 

 petal : filaments very capillary and as long as the calyx. Carpel only 

 one, gibbous, with a sublateral style, in fruit the coriaceous-utricular 

 achenium rising out of the cyathiform base of the calyx, and enclosed 

 by its conniving lobes. Cotyledons plano-convex, the short radicle 

 oblique, pointing to the base of the style. — It is really going too far 

 to rank this plant under Potentilla. 



Poterium officinale (Sanguisorba officinalis, L.), in a depaupe- 

 rate form, was collected by Mr. Bolander on the Mendocino Plains, 

 in 18G4: new to this continent. 



Gayophytum strictum : pube molli cinereum ; caule (demum pe- 

 dali) simplicissimo vel inferne parce ramoso rigido, a basi ad apicem 

 in axillis foliorum angusto-linearum crebre florifero ; petalis (incarna- 

 tis) oblongis bifidis calyce longioribus ; antheris stam. breviorum pol- 

 liniferis ; stigmate subclavato breviter bifido ; capsulis arete sessilibus 

 arrectis lineari-subulatis quadricostatis folia suboequantibus ; seminibus 

 in quoque loculo biseriatis ovalibus planoconvexis. — Dry hills, Clover- 

 dale, Sonoma Co., Bolander. Petals 1£, and capsules 5 or 6 lines long. 

 My original specimen of G. ccesium is too imperfect for verifying the 

 published characters ; but the present plant seems to differ sufficiently 

 in its strict and rigid habit, and closely sessile appressed pods with a 

 tapering point and much thicker valves, as well as in the stamens and 

 stigma ; and the seeds are more than double the size. The plant is 

 stouter than any other Gayophytum ; but the ovary is only 2-celled, 

 although the ovules are in four ranks. 



CEnothera (Godetia) Whitneyi : minute puberula ; caule valido 

 usque ad apicem crebre foliato ; foliis oblongo-lanceolatis subinteger- 

 rimis ; floribus confertis maximis ; calycis tubo obconico segmentis 

 multo breviore ; antheris linearibus ; stigmatibus linearibus elongalis ; 

 capsulis sessilibus (nunc subsessilibus) fusiformi-oblongis hirsuto-canes- 

 centibus (8-12 lin longis), loculis polyspermis ; seminibus adscenden- 

 tibus. — Plains at Shelter Cove, Humboldt Co. : " very striking and 

 ornamental," Bolander. Stem about a foot high, simple. Leaves 1 or 

 2 inches long, tapering to both ends. Calyx-lobes fully an inch long. 

 Petals fully 2 inches long, pink-purple, sometimes apparently with a 

 crimson spot about the middle. Stigmas 3 lines long. The most 

 splendid of all the Godetias, and very desirable for cultivation, from 

 the fine color and great size of the flowers, crowded at the summit of 

 the stem. In habit and in the capsule it is allied to (E purpurea, &c. ;
