FOUQUIERIA. OCOtillO. 



(Family Fouquieriaceae). 



Shrubs, rather few- and 

 arcuately-branched from near the 

 ground, with very sharp slightly 

 curved spines below the buds: de- 

 ciduous. Twigs moderate or 

 slender, rather fleshy, broadly 

 ridged below the nodes: pith 

 angular, continuous, (or becom- 

 ing chambered according to Sole- 

 reder). Buds small, spindle- 

 shaped, quickly developing into 

 ij I ^^f^^' short axillary leaf-clusters. Leaf- 



s?' flfn) scars found only on the axillary 



spurs or at the annual junctures, 

 minute, half-round, raised: bundle- 

 trace 1, minute: stipule-scars lack- 

 ing. Each spine represents the 

 dorsal part of the petiole of a 

 fallen foliage leaf. 



The second species, of Lower 

 California, forming a tapering 

 columnar trunk covered with slender ungrooved branches, and 

 with globose buds, is sometimes separated under the generic 

 name Idria. Incidentally, a grove of this is shown on plate 

 29 of the twenty-second Report of the Missouri Botanical Gar- 

 den, in a photograph by Mr. E. A. Goldman of the superb 

 agave subsequently named after him. 



Shrub: twigs flat-ridged below the spines. (1). F. splendens.
