5. LAPPULA PINETORUM Greene, Pittonia, 2: 182. 189gI 
Echinospermum pinetorum Greene ; Gray, Proc. Am. Acad. 17: 
224. 1872. 
This species appears from the specimens to be an annual. The 
following specimens are in the Gray herbarium : 
New Mex.: Pinos Altos Mts., July and September 1880, Greene. 
Arizona: Santa Rita Mts., 13 July 1881, Pringle, 349;

6. LAPPULA ARIDA Piper, Bull. Torrey Club, 28: 44. 1901 
In addition to the specimens cited in the original description 
the following are referable here : ; 
WasHincton : Without locality, 1889, G. R. Vasey, 479. 
OrEGon: Camp Harney, 26 May 1885, Howell ; Camp Har- 
ney, 1875, Captain Bendire ; Drew’s Valley, Lake county, d/rs. 
R. M. Austin 282, This specimen is referred to L. arida with 
considerable hesitation. 
The two following species are very near allies, and further ma- 
terial may compel their reduction. In all three the fornices of the 
Corolla are practically identical.
