* 
G. TrNncTroriumM diversifolium. Rather diffusely branched, 
stem angles more or less scabrous; leaves in fours, fives 
or sixes, often slightly scabrous on the margins and mid-rib; 
eorolla three- or four-parted, pedicels stouter than in G. éénctorium 
submontanum,; fruiting pedicels barely exceeding the leaves, 
stoutish, usually strongly divaricate., 
Arizona, California, Mexico: Willow Spring, Arizona, Palmer, 
No. 514; Bouldin Island, San Joaquin R., Mrs. Brandegee, 
July 9, 1893 (in part); Tamalpais, Brandegee; Valley of 
Mexico, Pringle, No. 6785. 
Palmer’s Arizona plant, No. 514, was assigned to G. fénctorium 
by K. M. Wiegand in Torr. Bull. xxiv, 397, but it agrees 
with the other specimens examined in the number of leaves, 
which is greater than in G. ¢inctorium of the Eastern States. The 
variety also has the pedicels strongly divaricate in fruit, which is 
not characteristic of G. tinctorium. ‘This variety is somewhat 
intermediate between G. ¢rifidum Claytoni and the type of G. 
tinctorium. 
G. siccatum. Perennial, one to four feet high, erect and 
very much branched and bushy when growing in some situations, 
or reclining in others; the whole plant cinereus-puberulent; leaves 
in fours, not rigid, linear, four to eight lines long, one-half to one 
line broad, barely mucronulate, mid-rib not prominent; inflores- 
cense cymose-paniculate, flowers polygamous, greenish-yellow, 
numerous; fruit a line broad, densely hispid with straight bristles. 
California, from San Diego north to San Benito County, and 
east to the Mojave: Del Mar, San Diego County, T. S. Brande- 
gee; Wilson’s Peak, Los Angeles Co., A. J. McClatchie, May, 
1896; Eagle Creek, San Benito Co., W. R. Dudley, June “ 
1899; [Eagle Creek plant grew out of rocks.] Antelope Valley, 
northwest of Mojave Desert, W. R. Dudley, No. cz. 
G. siccatum is most closely related to G. angustifolium, but may 
easily be distinguished from the latter, as the whole surface of 
G. siccatum is cinereous-puberulent. 
G. Coloradoense. Suffrutescent-perennial, twelve to eight- 
een inches high, inuch branched from the base, woody portions
