PSierra del Pajarito in Southern Arizona ; ft. August; collected 
only by the late Dr. Arthur Schott, 1855, to whose memory I 
have dedicated this species in consideration of long years of friend¬ 
ship and of the valuable services to science rendered by him in 
many arduous exploring expeditions in the arid southwestern 
wilds, as well as in the primeval tropical forests of the isthmus 
and on the plains of Yucatan. 
^ According to the discoverer, this as well as the next is one of 
the Amole or soap-plants. Leaves 6-12 inches long, 3-4 lines 
wide, terminating in a perfectly terete spine 3 lines long; margin 
splitting into numerous extremely fine whitish fibres. Scape 5-6 
feet high ; spike rather looser-flowered than in the last; primary 
and secondary pedicels about 1 line long; flower i| inches long, 
.ovary as well as narrow lobes about 5 lines, the gradually widen¬ 
ing tube 8 or 9 lines long, and bearing the filaments (8 lines long 
and reaching scarcely more than 1 line beyond the lobes) i£ lines
