blotched leaves of which I greatly admired. Botanists who visit us 
in these later days when man and the omnipresent sheep have done 
their worst with our fair lands have small conception of the astonish- 
ing luxuriance of the vegetation springing from the then almost 
virgin soil. 
-TRAGOPOGON PORRIFOLIUS L. ‘‘Salsify’’ or ‘‘ Oyster Plant” is 
now very freely naturalized in the northern part of the State. 
LACTUCA SCARIOLA L. ‘‘Prickly Lettuce” is becoming established 
in Berkeley. It was abundant last year near the entrance of the 
University grounds. 
ARCTOSTAPHYLOS NUMMULARIA Gray, was found by Mr. Brande- 
gee three years ago, growing abundantly on the eastern side of Mt. 
Tamalpais, and he has since brought it from the northern slope of 
the Bolinas range. In these localities it blooms sparingly during 
nearly the whole year. The plants are rarely more than eighteen 
inches in height, of a bright glossy green. The tall form found on 
Ben Lomond in Santa Cruz county has duller, less rounded leaves, 
and though often eight feet high bears a much greater resemblance 
to A. myrtifolia of Amador County, which can hardly be more 
than a mere variety distinguished by its tetramerous flowers and 
less rounded leaves. Dr. Parry was in error in stating that the 
fruit of 4. nummularia was covered by the persistent corolla. It is 
promptly deciduous in the thousands of plants observed in these 
various localities. The species appears to have a preference for 
the sandstone formations. : 
RHODODENDRON CatiForNicuM Hook. “ Rose Bay’’ has been 
recently collected on the side of Tamalpais above Corte Madera 
_by Miss Belle Brown. :

of this species described as produced by ‘‘a broad adnate and emar- 
ginate or obcordate scale’ is in fact caused by a series of arched 
saccate. protuberances, one at the base of each segment of the 
corolla, and the external surface bears as many corresponding de- 
pressions. It is often a much larger plant than described, forming 
tufts three or four inches high and as broad. It has been brought 
from the Mojave Desert, from Tehachapi, from Walker’s Basin, 
Kernville and Owens Valley.
