new, he very kindly supplied me with a good series of specimens from which 
the characters are drawn. It may at once be distinguished by its rather low, 
strict, usually monocephalous stems, its unusual pubescence, its almost 
lavender corollas, and the peculiar appendage-like appearance of the middle 
lobe of the lower lip. 
I am informed that it occurs rather sparingly in sandy soil near Boulder 
creek, Boulder, Colorado, where it was collected by Professor Ramaley (to 
whom it is dedicated) June 27, 1goo, no. 92. 

PHACELIA HETEROPHYLLA Pursh. The Rocky mountain speci- 
mens of this species seem somewhat aberrant, but the characters 
so far as made out do not seem to warrant separation. 
Mimutus Lancsporriu Titinct (Regel) Greene? A pecu- 
liarly pubescent form was sparingly represented. It seems 
probable that fuller material may show this to be distinct. 
LITHOSPERMUM LINEARIFOLIUM Goldie was represented by 
several numbers and showed much diversity. However, since 
these numbers represented different localities and plants in dif- 
ferent stages of maturity no dependence can be placed on the 
diversity shown. In this species and its allies successive col- 
lections shouid be made during the season from what 1s 
undoubtedly the same community of plants. 
CHRYSOPSIS FULCRATA Greene. What seems to bea pretty 
good match for the type number of this species, originally 
described from New Mexican material, was collected near 
Boulder, 
Oonopsis monocephala, n. sp —Caudex woody, its branches 
Slender: stems one or more from each branch of the caudex, 
frect or ascending, 1-2™ high, simple, uniformly leafy from 
base to summit, monocephalous: leaves glabrous as are also the 
stems, linear-oblong, sessile, acute, quite uniform in size and 
Shape, 5—g™ long, about 1™ broad, the uppermost involucrating 
the large head: involucre hemispherical, about 15" high; the 
bracts oblong, rather abruptly short acuminate-cuspidate, glab- 
rous but for some ciliate pubescence on the margins: heads 
tayless; disk flowers very numerous: pappus nearly as long as 
the corolla tube, the bristles widely spreading. at maturity: 
akene oblong, about 3™™ long, sparsely and obscurely glandular.
