Madia. COMPOSITE. 359 



* 



nected : akenes narrow and elongated, minutely and all sparsely hairy, even those 

 of the ray, the latter saliently 1 - 2 -nerved on each face ; outer ones of the disk 

 apparently fertile : pappus of almost setiform plumose unequal chaffy scales, the 

 longer ones little shorter than the corolla. Anisocarpus Bolanderi, Gray, Proc. 

 Am. Acad. vii. 360. 



Woods of the Sierra Nevada : in the Mariposa Sequoia grove, and at Conner Lake, Bolander. 

 Heads half an inch high : rays 3 lines long. Akenes 3 lines long ; those of the ray lanceolate- 

 falcate, sometimes bearing the rudiments of a pappus like that of the disk, but much reduced ! 



* * Disk-floivers loholly destitute of pappus, either all or only the central ones sterile: 

 leaves almost all alternate. (Madaria, DC.) 



3. M. elegans, Don. Pubescent, and more or less hirsute or even hispid, as 

 well as glandular, one or two feet high, or in depauperate slender forms only a span 

 or so in height : heads loosely corymbose or paniculate : scales of the involucre with 

 slender linear tips : rays (10 to 15 in the larger, 5 to 9 in depauperate forms) elon- 

 gated, acutely 3-lobed at apex, yellow throughout, or often with a brown-red spot at 

 base : disk-flowers all sterile, on a strongly convex hirsute-fimbrillate receptacle : 

 fertile akenes obliquely obovate, the areola at the thick truncate summit depressed. 



Madaria elegans &, M. corymbosa, DC., &c. M. racemosa, Nutt., one of the 

 slender forms. 



Hills and plains, throughout California and in Oregon and Nevada. Very variable in size, 

 pubescence, glandulosity, and number of flowers in the head ; but all apparently of one species. 

 The larger forms are handsome in cultivation. 



4. M. radiata, Kellogg. Viscid-pubescent and glandular, 2 or 3 feet high : 

 heads pretty large : scales of the involucre with short tips : rays 9 to 20, golden- 

 yellow, broadly oblong or somewhat cuneiform, obtusely 3-toothed : disk-flowers 

 also fertile except the central ones, on a nearly flat and glabrous receptacle ; their 

 akenes somewhat clavate and 4-angular, straightish, with depressed areola at 

 summit ; ray-akenes narrowly obovate-falcate, flat, tipped with a very short beak 

 which is rettexed upon the summit of the akene. Proc. Calif. Acad. iv. 190. 



Near the mouth of the San Joaquin River, Bolander. Head broad : ligules half an inch long, 

 abrupt at base. 



2. Rays short and more or less inconspicuous, 12 to 1, or rarely wanting altogetlier: 

 disk-flowers numerous or few, all fertile, destitute of pappus, and with corolla- 

 tube pubescent : receptacle flat and smooth. EUMADIA. 



5. M. sativa, Molina. Viscid-hirsute and glandular, heavy-scented, one to 

 three feet high : heads racemose or paniculate, often glomerate : ray-flowers 5 to 

 12 : disk-flowers about the same number : akenes obovate-oblong and slightly 

 curved, or those of the ray obovate-lunate, those of the disk commonly (and of the 

 ray sometimes) 1 -nerved down the sides. The following forms pass freely into 

 each other. 



Var. congesta, Torr. & Gray : a large and very glandular, common form : the 

 many-flowered heads sessile in crowded clusters : akenes (as in the Chilian plant) 

 rather narrow and mostly angled by the prominent nerve on the two sides. M. 

 capitata, Xutt., not "congesta" as printed in Torr. & Gray, Fl. ii. 404. 



Var. racemosa, Gray : a smaller and more slender form : commonly fewer-flow- 

 ered heads rather loosely racemose or panicled : akenes usual with less prominent or 

 obsolete lateral nerves. M. racemosa, Torr. & Gray. 1. c. Madorella racemosa, Nutt. 



Var. dissitifiora, Gray : like the preceding or more depauperate, with scattered 

 or panicled smaller and mostly fewer-flowered heads, often only 5 rays and as few 

 disk-flowers : akenes inclined to short-obovate (1 \ to 2 lines long), and with either 

 flat and nerveless or else 1-nerved sides. M. dissiiiflora, Torr. & Gray. Madorella 

 dissitiflora, Nutt.
