( Turckhi m 1 158). A species perhaps nearest to S. Canddaricc 

 Benth., but very distinct. 



PEREZIA NUDICAUL1S Gray. — Specimens from Guatemala, 

 Depart. Guatemala {J. D. S. 2364) show that the leaves are 

 not "all runcinate," some of them being simply ovate. 



Senecio Kermksixus Hemsl. {Gynoxys Heenkei DC.; 



Abundant material from Guatemala, Depart. Guatemala, alt. 

 5000 feet {J. D. S. 2356), shows that the original description 

 of De Candolle needs emendation, as that was professedly 

 drawn from imperfect specimens showing only the upper 

 leaves. The lower leaves are coriaceous, rugose veiny, and 

 more or less coarsely toothed. The heads also frequently 

 have more numerous flowers. The plant is a very handsome 

 one, climbing high over trees.

I. 1 Sauk NIGRA Marsh. — This species, in its distribution 

 from Texas southward and westward, presents two diverging 

 lines of variation. Southward, along the Gulf coast, it passes 

 by insensible gradations into the Mexican form of S. Huitt 

 boldtiana. Westward, across the plains of New Mexico and 

 Arizona, it takes on the character of var. venulosa Anders. 

 with the lower leaves of the branches oblong, rather obtuse, 

 often mucronate, later leaves at the tips of the branches 

 attenuate-linear, all yellowish-green (at least in herbarium 

 specimens) and veiny; mature capsules yellowish and long 

 pediceled. Var. Wrightii And. is the same thing only rep- 

 resenting (as it appears to me) an abnormal or retarded 



'The numbers correspond with those of the Flora of California.
