On the anomalous splitting of the rhizome and root of Delphinium 
scaposum 
MARGARET APPLETON KINGSLEY 
(WITH PLATES 13 and 14) 
Delphinium scaposum, first named by Greene,* is one of the 
xerophytic forms of the Ranunculaceae. The material used in this 
investigation was collected at the Desert Laboratory at Tucson, 
Arizona, under the kind direction of Dr. D. T. MacDougal of the 
Carnegie Institution. It was carefully killed at that time, and 
proved most satisfactory for anatomical study. 
As to its distribution, Huth,t who names it Delphinium decorum 
B scaposum (Greene) Huth, reports that it was mentioned by Parry, 
1874, as found in southern Utah, and by Pringle, 1883, in the 
Arizona hills near Tucson, the same territory from which this 
material was sent. Greene records its presence in the hill country 
between the Gila and San Francisco rivers, May 25, 1880, and says 
that Dr. Asa Gray informed him that Professor Newberry obtained 
what appeared to be the same, south of the Diamond River in 
Arizona.* In this same account, Greene gives the only adequate 
description of the plant, which I quote in part, as I have no ac- 
quaintance with the living form, ‘‘ Leaves all radical, rather fleshy, 
pubescent, 3-parted, the divisions broadly cuneate, 3-5-cleft or 
toothed, the teeth ending in a callous point, racemose at summit, 
pedicels as long as the deep azure flowers; spur incurved, root a
