one of them has short and broad lobes to the corolla of the disk. The glands are manifestly 
not of generic importance; and as in habit there is no longer a marked distinction, it will be 
evident, on comparing the characters of C. Fremontii with those of the two new Hemizonim 
above described, that it is becoming increasingly difficult to preserve Calycadenia as a genus, 
Т.АВОРНҮТЛА DICHOTOMA, Benth. Pl. Hartw. p. 317. On the Sacramento, California; Rev. Mr: 
Fitch. Branchlets only ; rays evidently yellow. The genus is distinguished from Hemizonia by 
the obcompressed fertile achenia, completely enclosed by the involucral scales, and by the cunei- 
form, deeply trifid rays. The habit also is peculiar. Yet, perhaps, it may be found to pass 
into Hemizonia ; though it is more distinct than Calycadenia.

Bot. Beech. Voy. Suppl. p. 356, On the Sacramento, California ; Rev. Mr. Fitch. The specimens 
are merely in flower. I suspect that in the achenia, no less than in other characters, as well as 
in habit, the plant will accord with ZLagophylla, and thus raise that genus to three known 
species. Тһе receptacle is not chaffy in the centre. The small rays are three-parted nearly to 
the base.

eupulam florem hermaphroditum includentem coalitis ; acheniis haud rostratris.—Sclerocarpus 
exiguus, Smith in Rees Cycl.; Hook. & Arn. Bot. Beech, Voy. p. 355, adn. California, (probably 
Mariposa county,) Rev. Mr. Fitch. Plant 2 to 4 inches high, including the fruit-bearing peduncles 
(which are an inch or more long); the branches diffuse. Root annual. Leaves from a quarter 
to half an inch long. Heads little over a line long, with 4 to Т ray-flowers, and a single 
hermaphrodite one, which is inclosed in a cup formed of only three pales. Besides this character, 
and the diminutive size and diffuse habit of this plant, it differs from H. madarioides, Nutt., of 
Oregon, in the less falcate ray-achenia, of barely a line in length (only half the size of those of 
the other species), the apex of which is obtusely apiculate, but not atallrostrate. Н. madarioides 
has, when young, a simple and strict stem, leaves of one or two inches in length, and, according 
to Nuttall, sometimes attains the height of 2 feet.

California; Parry. The genus should stand next to Jaumea, in the Heleniew, from which it 
differs principally in the want of the pappus.

excepting the original ones in Coulter's collection. They possess the lower cauline and radical 
leaves, which are pinnatifid, with few and unequal linear lobes, some of them 1—2-toothed or 
lobed. The root is that of a biennial or winter annual.
