10 PITTONIA. 
from Vancouver Island, distributed by Mr. Macoun, may be 
the same, but I have seen no specimens in fruit. 
The species next following may be regarded as segregates of 
M. attenuata, though the plants were not known at the time that 
species was published, and consequently have not affected the 
diagnosis of it; but several of them since have been referred to 
it by me as manuscript labels show. They are all at agreement 
with it as to the attenuation of the achene, which is only partly 
filled by the seed, the upper portion of the pericarp being 
vacant. 
M. CALLICARPHA. Leaves pinnatifid but not very deeply so, 
the divisions from triangular to subulate-lanceolate or subfal- 
cate: involucres oval: achenes scarcely 3 lines long, dark chest- 
nut-brown, the ribs sharply serrulate-scabrous, a few of the 
outer villous; pappus about 4 lines long, the oval and distinctly 
eymbiform palea dull-brownish, white-flecked with the usual 
minute appressed scaberulous hair, but not in the least villous, 
the aun of less than twice the length of the palea, 
Known to me only in a specimen preserved in my herbarium, 
taken out of the Botanic Garden at Berkeley in 1894, and named 
M. attenuata, I can not now recall from what part of Cali- 
fornia the seeds were derived. 
M. picta. Leaves narrowly lanceolate, entire, or some with a 
few coarse teeth or short-lobes: involucres oblong, 4 inch long : 
achenes 3 lines long, slender-fusiform, rather abruptly narrowed 
under the pappus and much more than half filled by the seed, 
white, but with numerous large oblong-linear flecks of black, 
the ribs very sharply serrulate-scabrous, a few of the outer very 
villous; pappus 43 lines long, the palea cymbiform sordid- 
brown, oblong-lanceolate, the awn one and a half times as long. 
Salinas Valley, Monterey Co., Calif., May, 1889, E. K. 
Abbott; the type in my own herbarium. 
M. LEIOSPERMA. Large; the many scapes stout, decumbent : 
leaves rather coarsely pinnate-parted: involucres very many-
