III. NOTES ON CERTAIN BORRAGINACEAE 
“ Lappula bella, spec. nov., perennis, circa 6 dm. alta; caulibus 
adpresse retrorso-strigillosis; foliis internodiis longioribus caulinis 
inferioribus oblanceolatis circa 10 em. longis 1-2 cm. latis apice 
acutis vel obtusis, basi in petiolum attenuatis, utrinque adpresse 
strigillosis et margine eciliatis, caulinis superioribus sessilibus ob- 
longis vel ovatis basi haud angustatis; inflorescentia ut apud L. 
diffusam; corollis verisimiliter albis 10-15 mm. latis; corollae ap- 
pendiculis pubescentibus non latioribus quam longis; nuculae facie 
dorsali 6 mm. longa; aculeis permultis (24-30), anguste subulatis 
basi non confluentibus. — CALIFORNIA: common on open slopes, 
Dorleska, in the Salmon Mts. of Trinity County, altitude 2000 m., 
July 21, 1909, H. M. Hall, no. 8599 (Typn, Gray Herb.). 
Dr. Hall referred this plant to L. diffusa, noting on the label the 
“pure white flowers’ and “‘ pubescent appendages.” Piper has 
shown, Bull. Torr. Club xxix. 535 (1902), the specific value of these. 
characters elsewhere in the genus. Furthermore there are in this 
case other differences of importance. In L. diffusa the blue corollas 
are only 8-10 mm. broad and their glabrous appendages are dis- 
tinctly broader than long; the dorsal faces of the nutlets are only 
4-5 mm. long and the prickles are uniformly fewer (9-14), much 
more strongly widened, and more or less joined, at the base. The 
pubescence on the petioles and the lower part of the stems is looser 
and more spreading than in L. bella. L. subdecumbens of the Rocky 
Mts. has white flowers and pubescent appendages but otherwise is 
not so nearly related to L. bella as is L. diffusa. The latter has not 
been found farther south than northern Nevada, its range being 
from Montana to Nevada and Eastern Oregon to Alberta and 
British Columbia, and so is far removed geographically.
