530 PLANTS FKOM LOWER CALIFORNIA. 



ones often entire, on long petioles ; calyx tube, 14 inches long, slender; 

 petals obco relate, 9 lines long; capsules becoming reflexed in age and 

 burying themselves in the sand ; Mowers rose-colored. The whole plant 

 more or less purplish, much resembling (E. primiveris, but capsule and 

 seeds very different. 



668. Megarrhiza. 



Perhaps distinct but nearest M. Californica. Fruit globose, 2 inches 

 in diameter, covered with weak, slender spines 8 to 10 lines long by 4 

 to 5 broad. The large root is used as a medicine. 



643. Apiastrum angustifolium Nutt. 



678. Galium aparine L., var. Vaillantii Koch. 



635. Aplopappus fasciculatus n. up. 



Belonging to the § Aplopappus proper. Herbaceous, a foot or two 

 high, glabrous ; leaves entire, linear-spatulate (1 to 1£ lines long), acute, 

 fascicled in the axils ; heads five to ten, in cymose clusters, 3 to G lines 

 high; bracts well imbricated in three or four series with indefinite green 

 tips; ray less; akeues pubescent; style tips short, broadly ovate. 



724. Pleuchea borealis Gray. 



605. Styloclyne gnaphaloides Nntt. 



699. Gnaphalium Sprengelii H. & A. 



But a single specimen collected. 



674. G. microcephalum Nutt. 



Not common. 



622. Franseria chenopodifolia Benth. 



This species, which for so long a time was unknown and variously re- 

 ferred to F. deltoidea and F. eriocentra, seems to be rather widely dis- 

 tributed. Orcutt collected it at All Saints Bay, 1885, by means of 

 which Dr. Gray re-established Beutham's species; also collected by 

 Hinds at Bay of Magdalena, E. L. Greene at Cedros Island, aud now 

 by Dr. Palmer at San Quentin. 



664. Viguiera laciniata Gray. 

 661, 662. Encelia Californica Nutt. 

 677. Leptosyne Douglassii D. C. 



Its most southern range. 



602. Layia elegans T. & G. 



The rays are only yellow near the base, the remainder purple or 

 white, three-quarters of an inch long, the hairs on the pappus sparse 

 and hardly woolly, and about one-third their length. Stems mostly sim- 

 ple; only the uppermost leaves entire. Orcutt has also collected a 

 purple-flowered form at All Saints Bay (1885). 



634. Baeria gracilis Gray, var. paleacea Gray. 



Plant much brauched and spreading at base; heads 2 to 3 lines 

 high; bracts six to eight, erect and close; rays small (1 to2 lines), barely 

 exserted. Collected by Orcutt in 1881 and distributed as the var. tener- 

 rima. This plant differs somewhat from the var. paleacea in most 

 herbarium specimens, but Orcutt's plant was referred here by Dr. Gray.
