11 October, 1899, ZH. W. D. Holway, no. 3617 (type, in hb. Gray); 12 
November, 1905, C. G. Pringle, no. 13,672; in granitic soil on the 
Sierra Madre of Michoacan or Guerrero, alt. 1100 m., 6 September, 1898, 
E.. Langlassé, no. 576. This species is near C. peltata HBK., buts 
readily distinguished by its leaves, which are less deeply lobed, the 
lobes not again sinuately lobed, and by the smaller exceedingly narrow “A 
bractlets, those of C. peltata being foliaceous. 
Cacatta LazvicaTa Sch. Bip. ex Klatt, Leopoldina, xxiv. 125 (1888) : 
Senecio heteroideus Klatt, l.c. (1888). Cacalia longipetiolata Robinson & 
Greenman, Am. Jour. Sci. 1. 157 (1895). When in 1895 the authors 
of C. longipetiolata characterized that species they knew C. laevigata 
only from Klatt’s description. A drawing and some fragments of the 
type of C. laevigata, subsequently received at the Gray Herbarium by 
the purchase of the Klatt Herbarium, prove beyond doubt the identity 
of C. longipetiolata with C. laevigata, a correspondence which coul 
scarcely have been inferred from the brief and in some respects mislead- 
ing characterization of C. laevigata given by Klatt. oS
