 have the same pale color. It was found in company with 9253 

 referred to above under V. venosa, growing below a snow bank, 

 and bore fruit only, while the other was in full flower. 



In Pittonia 3: 38, Dr. Greene states that V. Nuttallii be- 

 longs strictly to the Rockv mountain region. This may very 

 well be true, for most violets have a rather limited distribution.

Aulospermum Bethcli sp. nov. 



Leaves and peduncles arising from a strong perennial root, 

 this often clothed at top by old leaf sheaths: the scape leafless, 

 remarkably stout, purplish at base, 6 to 15 cm. long, exceeding 

 the leaves: the leaves from broad, clasping, scarious sheaths, the 

 petiole more slender than the peduncle, 3 cm. or more in length, 

 the blade broadly ovate in outline, ternate and bipiunate, the 

 rachis of the leaflets winged, the leaflets rather broad, coarsely 



toothed and the teeth sharp 

 pointed: rays of the umbel 2 to 



4 cm. long, the fruiting pedicels 



5 to 8 mm. long: involucre none: 

 involucels of several linear, acu- 

 minate bracts: flowers purple(?): 



fruit 7 to 8 mm. long, 6 to 7mm. 



Figure8. .1. Betheli x 5 diameters -i , 1 . n ' ,- , , 



wide, with three to five broad 



wings not thickened at the base: oil tubes | on the coillissure, 

 3 to 5 in the intervals: seeds somewhat flattened dorsally, with 

 a broad concavity. 



This species somewhat resembles- \ulospermum purpureum 

 'Wats.) C. & R., and I suppose is nearest to it, but seems to be 

 somewhat Stouter, and has four oil tubes on the comissure in- 

 stead of eight. Collected .it DeBeque, Mesa county, Colorado,
