FOUQUIERIACEAE. 239 
FouQquUIERIA. 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 
short axillary leaf-clusters. Leaf- 
sears 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 /dria. 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.
