Cotula coronopifolia, Linn.; DC. 1. c. p. *18. Swampy places, Benicia, California; April. 
Laguna, near San Francisco, Mr. H. G. Bloomer. Dr. Bigelow does not seem to have thought 
this an introduced plant; but it was probably brought to California from the Old World. 
Artemisia dracunculoides, Pursh., FI. 2, p. 742 ; Torr. & Gray, FI. 2 ,p. 416. Rocky hills

hills on the Canadian ; August. 
Artemisia Bigelovii (sp. nov.) : fruticosa, humilis, incana ; foliis utrinque albo-sericeis 
cuneato-linearibus seu augustissime cuneatis apice tridentatis, floralibus parvis integerrimis; 
capitulis obovatis parvis glomeratis longe spicato-paniculatis ; involucro tomentoso seepissime 
trifloro ; floribus 2 hermaphroditis, unico foemineo ; corolla glabra. Rocks and canons on the 
Upper Canadian and Llano Estacado. A much branched, shrubby species, apparently only a 
foot high, and of the section Abrotanum ; very canescent all over, the crowded leaves and 
branchlets with a fine and close silvery sericeous pubescence, the heads (which are glomerate, 
into a strict and virgate, interrupted, spicate panicle, of fully the length of the leafy branches) 
more tomentose. Leaves 3 to 7 lines long, 1 to 2 lines broad at the truncate and 3-toothed or 
3-lobed apex, thence tapering to the base, equally silky-canescent on both sides, the broader 
ones triplinerved above ; the floral ones very small, filiform-linear, entire, scarcely as long as 
the glomerules they subtend. Heads a line and a half long, usually three-flowered, sometimes 
only two-flowered, but one of them always slender and pistillate only, apparently all of them 
fertile. Scales of the involucre oblong, obtuse ; the exterior with slight scarious margins, the 
innermost scarious, villous-ciliate. This might be mistaken for a small and narrow-leaved stato 
of A tridentata, Nutt.; but the heads are smaller, more hoary, fewer-flowered, and heteroga.

maphrodite.
