408 COMPOSITE. 



leaves from the rootstock: leaves about 3, cordate or ovate, entire, 3 — 5 

 in. long: outer bracts of involucre foliaceous, oval; inner narrow and 

 villous. — Foothills of the Sierra, from Amador Co. to Placer. 



50. WYETHIA, Nuttall. Vegetative characters of Balsamorrhiza, 

 and like that genus, flowering in spring, but the stout stems in our 

 species leafy. Achenes prismatic-quadrangular, crowned with a short 

 pappus of united or nearly distinct rigid scales or awns. 



1. W. heleiiioides, Nutt. Trans. Am. Phil. Soc. vii. 353 (1840); DC. 



Prodr. V. 537 (1836), under Alarfonia. Soft-tomentose, becoming less so 

 in age, 1 — 2 ft. high, very stout and leafy: leaves oblong, or oblong- 

 ovate, the lowest a foot long or more: heads very large, the disk 2 in. 

 broad, the rays also long and broad: outer bracts of the foliaceous invo- 

 lucre ovate and ovate-lanceolate, occasionally toothed: achenes some- 

 what pubescent at summit. — Hillsides of the Mt. Diablo Range; very 

 early-flowering. 



2. W. glabra, Gray, Proc. Am. Acad. vi. 543 (1865). Size and habit 

 of the preceding, but glabrous and balsamic-viscid; leaves occasionally 

 serrate: achenes glabrous. — Middle Calif ornian, like the last, but of the 

 Coast Range proper, and to the seaward. 



3. W. longicaiilis, Gray, Proc. Am. Acad. xix. 4 (1883). Glabrous 

 and balsamic-viscid, tall and rather slender, 2 ft. high: leaves lanceolate: 

 heads solitary or panicled, the disk scarcely 1 in. broad: outer bracts of 

 the involucre oblong or spatulate, foliaceous, surpassing the disk; rays 

 only 1 in. long: achenes with a short erose-denticulate crown. — Prairies 

 of eastern Humboldt Co., Rattan. 



4. W. reticulata, Greene, Bull. Calif. Acad. i. 9 (1884). Tall and 

 leafy, puberulent-hispidulous without woolliness, the heads several and 

 corymbosely disposed: leaves shining, ovate or subcordate, 2 — 4 in. long, 

 3 — 5-nerved, and with veins and veinlets much reticulated: heads only 

 % in. high; bracts of involucre short, obtuse: rays few and small: 

 achenes glabrous; pappus a short erose-denticulate crown. — Banks of 

 Sweetwater Creek, El Dorado Co., Mrs. Curran. 



5. W. ovata, T. & G., in Emory's Rep. 143 (1848). Canescent with a 

 soft but not woolly pubescence, 2—3 ft. high from running rootstocks, 

 branching: leaves ovate, the upper subcordate, acute, 3-nerved, scarcely 

 reticulate: bracts of involucre broadly lanceolate, not surpassing the 

 disk: pappus a chaffy several-toothed crown. — Obscure species of south- 

 easterly habitat, perhaps beyond our limits.
