one of tliem has short and Lroad lohes to the corolla of the disk. The glands are manifestly 

 not of generic importance ; and as in habit there is no louger a marked distinction, it will he 



evident^ on comparing the characters of C, Fremontii with those of the two new Ilcmizonia) 

 above described, that it is becoming increasingly difficult to preserve Calycadenia as a genus. 



LAQoriiYLLA DicHOTOMA, Bcnili. PI, Hartio. p. 817. Oq the Sacramento, California ; Itev. 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.

Hooh. & 



Bot, Beech. Voy. SuppL p. 356, On the Sacramento, California ; liev. 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 Lagophylla^ and thus raise that genus to tliree known 

 species. The receptacle is not chaffy in the centre. The small rays are three-parted nearly to 



the base. 



Madia sativa, Molina. In springy places, California, near Monterey ; April. 



HARP-^CARrus EXiGUUS: tenellus, diffusus ; pedunculis filiformibus ; paleis receptaculi 3 in 

 cupulam florem hermajihroditum includentem coalitis; acheniis hand rostratris. — Sclerocarims 

 exiguus, Smith in Bees Cycl.; Hook. <& Am. Bot. Beech^ Voy. p 355, adn. California, (probably 

 Mariposa county,) Bev. 3Ir. Fitch. Plant 2 to 4 inches high, including the fruit-bearing peduncles 

 (which are an inch or more long); the branches diffuse. Koot annual. Leaves from a quarter 

 to half an inch long. Heads little over a line long, with 4 to 7 ray-flowers, and a single 

 hermaphrodite one, which is inclosed in a cup formed of only three palete. 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 at all rostrate, H. 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. 



CoIjS'ogyxe caknosa, Less.; DC. Prodr. 6, p. 42. Salt j)laces and seashore near San Diego 

 California ; Parry. The genus should stand next to Jaumea, in the Helenie^e, from which it 

 differs principally in the want of the pappus. 



Baileya pauciradiata, Raw. & Gray, in PL FendL p. 105. Diluvial banksof the Colorado, 

 Sonora ; February, 1855 ; Schott. These are the only specimens of this plant I have seen, 

 exce])ting 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 l-2-'toothed or 

 lobed. The root is that of a biennial or winter annual. 



Baileya pleis^iradiata, Harv. & Gray, I. c, d: PL Wright. L c. Very common from the Hio 

 Grande to the Colorado, Sonora^ etc. 



I tripaleato trifloro, corollae lobis oblongis ; achenio radio laevi obtuso, lis disci hirsutulis pappo lO-paleaceo (paleis alternis subulato- 



* ^ productis) longioribus. — California ; CoL Fremont, This species presents nearly tTie habit of C. tenella, except that the pro- 



j longed branches are simple or sparingly forked, and bear lateral nearly sessile beads ; and they are scarcely, if at all, glandular 



ll or viscid. The heads are still smaller, or at least narrower, and, as far as examined, have unformly only one ray and three 



disk flowers ; the latter surrounded by a cup formed of the thin coalescent paleaa. Pappus nearly as in C. Premontiu Ray- 

 achenium rather acute at the bare, but the summit not at all apicufate. ^
