Madia. COMPOSITE.. 359 



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

 of the ray, the latter saliently 1 - 2-nerved ou 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 Mnripcsa Sequoia grove, and at Donncr Lal<e, Bolandcr. 

 Ileaiis lialf nn 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-flowers wholly destitute of pappus, either all or onlij the central ones xterile : 

 leaves almost all alternate. (Afadaria, J)C.) 



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 3dobed at apex, yellow throughout, or often with a brown-red spot at 

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

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

 — Madaria elegans k M. corymhosa, DC, (tc. J/, 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, yiscid-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-llowers 

 also fertile except the central ones, on a nearly Hat 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 reflexed upon the summit of the akene. — Proc. Calif Acad. iv. 190. 



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

 abrupt at base. 



§ 2. Rays short and more or less inconspicuous, \2 to \,or rarely wanting altogether: 

 disk-flowert numernus or few, all fertile, destitute of pappus, and with corolla- 

 tube pubescent : receptacle flat and smooth. — I'^umadia. 



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) l-ncrved down the sides. — The following forms jiass 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 tlie two sides. — M. 

 capitata, Nutt., not ''congesta" as printed in Torr. & Gray, Y\. 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. — Af. racemosa, Torr. <fe Gray, 1. c. Madorella racemosa, Nutt. 



Var. diSSltiflora, Gray : like the preceding or more dopauperalo, with Rcatten>d 

 or panicled smaller and mostly fower-flowered bonds, oflm oidy f) rays nnd us fi>w 

 disk-llowers: akenes inclined to short-obovate (I^ to 2 lines long), nnd with cither 

 flnt nnd nerveless or else "l-norved sides. — JA dissitiflora, Torr. it Gray. Madoi-ella 

 dissitipmi, Nutt. •
