flowers half that size, from light to deep purplish blue, not 
distinctly blue-veined, the circular white center more or less 
punctate; inter-staminal scales short, wide and short hairy; 
ovary longer than in N. intermedia and with 20 to 32 ovules,

N. atomarta, F.& M. With the habit of N. intermedia 
but less hairy and growing only in springy places among the 
hills; corolla less than one inch wide, white with a slight 
tinge of violet on the outside of the tube, closely dark-spotted 
nearly to the edge, densely hairy within the tube; inter-stam- 
inal scales narrow and long-hairy; ovary rounded and less 
hairy than that of the two foregoing species, ovules about 
16. Ind. Sem. Hort. Petrop. (1835). Bot. Reg. t. 1940 
The figure of the scale is drawn from a plant from Caza-

The color of the flowers is variable in the first two species, 
but NV. insignis is generally more deeply colored, of a less 
pure blue and with a white center of more distinct circular 
outline. The spots are very variable in both species. At 
Lake Merced, San Francisco and at Pomona the corolla of N. 
insignis is almost destitute of spots, while specimens of the 
same species from Tulare are more densely spotted than any 
specimens of N. intermedia that I have seen; but in neither 
species do the spots extend to near the edge of the corolla as 
in N. atomaria.
