minimis ; sepalis oblongis obtusiusculis vix ciliolato-glandulosis : pe- 

 talis albis basi utrinque subunidentatis ; sinubus inter stamina dente 

 brevissimo glandukeformi instructis ; stylis 3 ; stigmatibus subclavatis 

 recurvis. — On Mount Bullion, Mariposa Co., Bolander. About a foot 

 higb. Flowers as much smaller than in the preceding as those are 

 than in L. Ccdifornicum, even smaller than in L. Virginianum and 

 L. striatum, Walt. (L. opposiUfolium, Eugelm.). This differs from 

 the four other trigynous species now known, in wanting the little 

 appendage to the face of the claw of the petal, and the lateral teeth 

 are less distinct. The three false partitions of the globular capsule 

 are almost complete. (In the old Linum trigynum of our conser- 

 vatories I can no more find even a trace of appendages to the 

 petals in fresh flowers, than could Bentham and Hooker in dried 

 specimens. So far as regards this species the genus Reinwardtia 

 has no characters. 



Linum digynum : annuum, glabrum ; caule exili (spithamajo) apice 

 subcymoso-plurifloro ; foliis oppositis oblongis (lin. 3-6 longis) ; glan- 

 dulis stipularibus nullis ; pedicellis strictis calyce brevioribus ; sepalis 

 oblongo-lanceolatis obtusis uninerviis margine lacerato-denticulatis 

 gkndulosisque ; petalis flavis ; dentibus inter stamina nullis ; stylis 2 

 liberis; stigmatibus capitatis; capsula quadrilocellata. — Mariposa Trail, 

 Yosemite Valley, rare, Bolander. — Flowers small, but rather larger 

 than in the foregoing. Petals not appendaged at the base. While all 

 the other peculiar Californian species are trigynous, this is digynous ! 



Lupin us Breweri : fruticulosus, ramosissimus, casspitoso-humi- 

 fusus, pube appressissima argenteo-sericeis ; stipulis subulatis ; foliolis 

 7-10 spathulatis cuneatisve retusis (lin. 3 -4 longis) ; racemo brevi 

 (pollicari) densifloro ; calycis bracteolati labio superiore bipartito ; 

 corolla violaceo ; carina vix ciliata. — " Prostrate, trailing on the 

 ground or on rocks, on the Yosemite trail, alt. 6,000 feet," Prof. 

 Brewer. Nevada near Carson, Dr. C. L. Anderson ; a form with 

 flowers only 3 lines long, the keel not in the least ciliate ; Avhile in 

 Prof. Brewer's specimens the flowers are 4 or 4| lines long, and with 

 a few hairs on the margins of the keel. — This ranks with the andine 

 species forming Agardh's tribe Microphylli. 



Lupinus Lyalli : fruticuloso-ca3spitosus, nanus, hirsuto-sericeus : 

 stipulis subulatis ; foliolis 5-6 obovato-oblongis (lin. 3-longis) ; pe- 

 dunculo scapiformi nudo bipollicari capitulum multiflorum gerente ; 

 calycis bracteolati labio inferiore tridentato, superiore bipartito; corolla
