3292 PITTONIA. 
Deserts of eastern Oregon, W. C. Cusick, 21 June, 1898; 
distributed under n. 1956, for M. adoratissima, but very 
different, representing a strongly marked new species. 
⁄ M. nervosa. Stems fewer from the stout woody base, 
taller, usually 12 to 18 inches high: leaves ovate- and 
oblong-lanceolate, obtuse, entire, prominently veiny beneath, 
plane above, about $ inch long, notably shorter than the 
internodes, hoary-tomentulose on both faces but most so 
beneath, only sparsely punctate: heads about 1 inch 
broad; braets ovate-oblong, villous-tomentose and strongly 
woolly-ciliate: body of the calyx nearly glabrous, the teeth 
strongly villous-hirsute: corollas white. 
Distributed by Sandberg & Leiberg from the arid region 
of eastern Washington in 1893, under the name of M. 
adoratissima, which is a plant of quite other characters.
