(1906). Achenes with straight ribs, or the inner ones smoothish 

 or merely costate. Palomar, San Jacinto, and San Bernardino 

 Mts., north to British Columbia, and on the islands from Guada- 

 lupe at least to Santa Cruz. 



f. kymapleurum Greene, Bull. Torr. Club x. 88 (1883), as var. 

 Macrorhynchus heterophyllus Nutt., Trans. Am. Philos. Soc. ser. 

 2, vii. 430 (1841). Kymapleura heterophylla Nutt., 1. c. errat 

 455. Agoseris heterophylla kymapleura Greene, Pitt. ii. 179 

 (1891). Ribs of the outer, and sometimes also the inner achenes 

 corky-thickened and beautifully sinuate or undulate. A common 

 form, usually with the species, but not yet detected in Southern 

 California. It will be noted that this is the form first named 

 and described and therefore represents the taxonomic type of the 

 species, while f. normale evidently represents the morphologic 

 type. 



f. cryptopleurum Greene, Bull. Torr. Club x. 88 (1883), as 

 var. Agoseris heterophylla var. cryptopleura Greene, Pitt. ii. 

 179 (1891). A. heterophylla California Piper, Contr. U. S. Nat 

 Herb. xi. 544 (1906) ; not Cryptopleura Calif ornica Nutt. Outer 

 achenes or some of them much inflated and inconspicuously 

 striate, not at all ribbed or winged. Also with the species in 

 middle California and northward but not yet seen within our 

 borders. 



Var. Calif ornicum (Nutt.) Hall, comb. nov. Cryptopleura 

 Calif ornica Nutt., Trans. Am. Philos. Soc. ser. 2, vii. 431 (1841). 

 characters extended. Plant usually larger and coarser than in 

 typical T. heterophyllum; scapes 15 to 45 cm. high : ligules con- 

 spicuous, about 1 cm. long, much exceeding the involucre : achenes 

 exhibiting a series of variations exactly parallel with those of the 

 species. 



Var. Californicum f. idiale Hall, form. nov. Achenes with 

 straight ribs or the inner ones with straight striae. Near Goshen. 

 Tulare Co., Brandegee, as formerly represented in the Herbarium 

 of the California Academy of Sciences; New York Ravine, El 

 Dorado Co., Mrs. Brandegee (Herb. Univ. Calif, no. 88020) ; 

 Simpsons, El Dorado Co., Mrs. Brandegee (Herb. Univ. Calif, 

 no. 88021). Several other collections are intermediate between 

 this morphologically typical form and the next.
