As yet, it is imcertaiii wlietlier the following are mere varieties of one, or wlietlier they retain 

 their small distiintions uniformly. If at length redueeil to one the iianio A. curoiuiria should bo 

 preferred, Nuttall's name (probably suggested by a likeness to Chrysanthemum, cm-oiuirium) being 

 a year or so earlier than llijiiicnoxys Cati/oniicu of liooker. 



* Minutely ylioidular-pubescent : rays 10 to 15, elonr/ated-oblony : involucral scales 



oliUmy-lanceulate : receptacle pubescent, 



1. A. coronaria, timy, 1. c. Dillusi'ly hmucliiug elendor stoms a foot loiif,' : 

 pappus ul" 10 (or 8 Lu 12) iiiuceolHto or oblong cleiiUouliito scales, all tapering into 

 awns a little shorter than the disk-corollas, or in the ray fewer and some of them 

 awnless. — Ptilomeris coronaria & P. aristata, Nutt. in Trans. Anier. Phil. Soc. vii. 

 382, Shortia Calif arnica, Nutt. in garden catalogues. Hymenoxys Calif ornica, 

 Hook. ]>ot. Mag. t. 3828 ; Torr. & Gray, Fl. ii. 280, with var. coronaria. 



Near San Diego, Nultall. So far as we know collected only by him, and in cultivation from 

 his seeds. l)e.scribed as " very glabrous" in the Botanical Magazine, doubtless incorrectly. Rays 

 nearly half an inch long, usually VI. 



2. A. anthemoides, Gray. Leaves perhaps more copiously divided and glan- 

 dular, and heads rather smaller : pappus none. — Ptilomeris (Ptilopsis) anthemoides, 

 Nutt. 1. c. Hymenoxys calva, Torr. tt Gray, 1. c. 



AVith the preceding, Nuttall. Also towards Julian City, Bolander. 



3. A. mutica, Gray, 1. c. Like the foregoing : pappus of 6 to 8 quadrate-oblong 

 scales, eiose-laciniate at the truncate or very obtuse summit, shorter than the proper 

 tube of the corolla, occasionally one or two of them slightly awned. — Ptilomeris 

 mutica, Nutt. 1. c. 11 ynienoxys mutica, Torr. & Gray, 1. c. 



Near San Diego, A^ul/a/l ; by whom only it has yet been collected. 



« * More or less pubescent, but hardly if at all glandular : rays G to 8, shorter, oval: 

 involucral scales ovate : receptacle glabrous. 



4. A. tenella, Gray, 1. c. Smaller than the foregoing : the heads and leaves 

 about half the size of those of J. coronaria : lobes of the latter shorter and blunter 

 as well as fewer : i)appus of 5 to 8 short quadrate scales, which are lind)riate at the 

 broad sunuuit, or some of them occasionally bearing a delicate short awn. — Ptilo- 

 meris tenella, ^k, P. ajjinis, Nutt. I'l. (Jamb. 173 ; llu) latter a form with some of the 

 l>appus awned. 



Near Los Angeles, Gambd. Eays 2 lines long. 



§ 2. Floccose-woolly : most of the leaves alternate: invohicre narrow: rays rather few, 

 obovale : receptacle convex or obtusely conical : akenes mimitely liairy or some- 

 times glabrous : pajtpus 0/ 8 to 10 or more scales or squamelUe. — True 



ACTINOLEPIS. 



* Heads small and sessile or leafy-brncted, with only 5 {or " 3 to 5 ") yellow rays : 

 receptacle merely convex : anther-appendages ovate- lanceolate : pappus of subulate or 

 almost setifonn scales, commonly wanting in the diskjlowers. {Actinolepis, DC.) 



5. A. xnulticaulis, DC. Seldom a span high, dilfuscly branched from the 

 base, the white wool below somewhat deciduous with age : leaves cuneate or spatu- 

 late with a long tapering base, the summit obtusely 3-toothed or 3-lobed : scales 

 tif the ])appus 10 to 15, une.(]ual, very slendcn-, usually (but not always) wanting in 

 all the disk Uowers. — llouk. Ic. t. 325 ; IJut. Mc.\. IJound. t. 33.
