CHICORIACEOUS COMPOSIT^E. 49 



linear-lanceolate, 4 lines long, the awn very little shorter. — 

 Prod. 1. c. ; Microseris, Gray, 1. c. 



From San Francisco to San Diego; equally as common as 

 the first species. 



0. Parryi, G-ray. Furfuraceoas-puberulent, 6 — 8 inches 

 high: akenes 3 lines long, and not at all attenuate; palea 

 softer than in the last, its awn less than half as long. — Pac. 

 R. Rep. iv. 112; Microseris, Gray, 1. c. 



Common from the plains back of Mt. Diablo to San 

 Diego: easily mistaken for small C. LincUeyi, but, on closer 

 inspection, appearing clearly distinct. The fruit is here for 

 the first time described. The species does not appear to 

 have been collected save by Dr. Parry, in a very immature 

 condition, and by the present writer; but it is no rarity in 

 the field. 



H~ -5- Aiun of the pappus longer than the palea. 



0. MACROCH^rA, Gray. — Like 0. Lindleyi in size and as- 

 pect, but akenes shorter and more attenuate at summit; 

 palea short, only a third as long as the awn, and cleft to the 

 middle.— PI. Fenld, 112; Pac. R. Rep., 1. c. 



From Oregon to San Diego, but very rarely collected. 



C. Kelloggii. — Also resembling G. Lindleyl: akenes 3 — 4 

 lines long, attenuate at each end: palea a third the length 

 of the awn, and with a shallow notch. 



San Bruno Mountains, near San Francisco, Dr. Kellogg. 



SCORZONELLA, Nutt. 



Involucre campanulate; bracts herbaceous, imbricated in 

 in several series, the inner long-acuminate, the outer suc- 

 cessively shorter and acute. Receptacle flat or convex, fov- 

 eolate or alveolate. Akenes linear, or somewhat turbinate, 

 8 — 10-costate or -striate, truncate at summit, the basal cal- 

 losity acute and not expanded, areola lateral. Pappus of 

 about 10 (in one species 5) ovate or lanceolate paleoe, tipped
