SPECIES OF LAPPULA 547 
fruit 6-8 mm. long, shining, covered all over with subequal glo- 
chidiate separate prickles; ventral surface smooth, the scar 
central. 
This is apparently the commonest California species. It is 
readily distinguished from all others at a glance by its velvety 
pubescence, its large blue salverform corollas, and the very promi- 
nent corolla appendages. 
The following specimens have been examined, all from Cali- 
fornia: General Grant Grove, 20 July 1892 (type in herbarium 
California Academy of Science), Brandegee ; General Grant Park, 
I-13 July 1899, Eastwood ; Lake Tahoe, June 1900, Miss King ; 
Lake Tahoe, July 1895, Abraham; Lake Tahoe, Lemmon, Tu- 
lare county, June 1896, Purpus, 1777; Humboldt county, 1885, 
C. C. Marshall; Amador county, June 1886, Mrs, Wiley ; Arm- 
strong Station, 13 June 1895, G. Hansen, 1141; Summit, EI- 
dorado county, July 1899, Blaisdell, 96. 
__ The Cusick specimen was distributed as a new species but on 
further study it is thought best to refer it here. 
It has been a matter of some difficulty to decide upon a type for 
this species, inasmuch as Dr. Gray confused three very different 
plants under one name and did not definitely indicate a type either 
in the published description or in his herbarium. The difficulty is 
easily understood from his original description which follows : 
ae Comparatively large-flowered, perennial, with tube of the corolla surpassing 
the calyx and about the length of the lobes: nutlets of the globose fruit equally armed 
over the whole surface and margins with long and slender but flattish minutely glochid- 
late prickles, 
“E. Cauirornicum. £. diffusum Gray, Syn. Fl. (exéluding small-flowered 
Specimens which belong to the true Z. diffusum, and excl. syn. Kellog?) not of Lehm. 
Sierra Nevada, California, from Mount Shasta southward. This was taken for Leh- 
Mann’s Z, diffusum, because of his description of the corolla (‘ Corolla alba? magna, 
tubus calyce paullo longior sensim ampliatus’ ); and Californian specimens of the real 
£. diffusum were mixed with it, The original specimens of the latter do not have the 
€xserted tube of the corolla which marks the present species when in blossom, as does 
the fruit at maturity. It is the Z. mervosum of Kellog; but neither the leaves nor the 
Sepals are perceptibly nervose(the former not ‘ 3-5-nerved ’ nor the latter ‘ 3-nerved’), so 
that the name would be a false one.’’ 
It is perfectly clear that the flower characters of the above de- 
_ Scription were taken from the specimens L. velutina and L. nervosa 
8S they alone have salverform corollas. The fruiting characters 
_ Were drawn from the Brewer and Pringle specimens, perhaps also
