FOUQUIERA SPLENDENS Engelm. 



Branching near the base, sending up 

 numerous divergent simple slender 

 stems few to 20 ft. high, with ashy- 

 gray bark and large pith; leaves 

 strongly grooved and ridged by the 

 decurrent bases of the spines, spatu- 

 late to obovate, % in. long, the prima- 

 ry attenuate into rigid petiole: fls bril- 

 liant crim?on. on short pedicels in nar- 

 row nearly simple terminal racemes. 

 Hocotillo or candle wood, the straight 

 poles (when dry) excellent for torches, 

 and often cut for fences. Abundant 

 from the western precipitous slopes of 

 the Colorado desert' to El Paso, Texas, 

 south into Baja Cal., Sonora, and to 

 the state of Durango. Mexico. Curious 

 at all times, brilliant in flower. Stems 

 have produced leaves and flowers 

 many months after being cut and 

 stored in a house on an increase in the 

 humidity of the atmosphere.
