 Calif. Acad. Sci. ii. 34. — Armed shrubs or small trees (nearly or quite leafless 

 during drought) with terminal racemes or panicles of showy flowers. Leaves of 

 the primary shoots and developed branches soon deciduous, leaving only the in- 

 durated outer or ventral portions of the petioles as phyllodial thorns (Engelm. 

 Bot. Gaz. viii. 338) in the axils of which the more or less' succulent foliar leaves 

 are fascicled. Anomalous genus, of four species, chiefly Mexican and Lower 

 Californian. 



F. splendens, Engelm. (Coach-whip.) A shrub, 6 to 10 or even 20 feet high, branching 

 near the base : long branches gray, deeply furrowed between the decurrent bases of the 

 slender spreading spines : leaves obovate, rounded at the apex, cuneate at the base, 1 -nerved, 

 half inch to inch in length ; inflorescence racemose, thyrsoid, elongated, often branched 

 from the base, rather dense ; pedicels short : sepals rounded, subscarious, 3 lines in diameter : 

 tubular corolla briglit scarlet, over an inch in length, with spreading or recurved obtuse 

 lobes: stamens 8 to 12, exserted: capsules 6 to 8 lines in length, with 3 or 4 lance-oblong 

 coriaceous valves ; seeds white, lance-oblong, with long fringe of spirally thickened hairs. —

 147, t. 8, not HBK. — Rocky hillsides, W. Texas to Arizona and S. California. (Mex., 

 Lower Calif.) Often cultivated by the Mexicans to make impenetrable hedges. 



F. SPINOSA, IIBK. 1. c. iii. 452 (Bronnia spinosa, HBK. 1. c. vi. 83, t. 528), of Northern 

 Mexico, may be expected on our southwestern frontier. It has a trunk simple below, and may 

 be readily distinguished from the foregoing by its broad and open inflorescence (the slender 

 pedicels being 6 to 12 lines in length).
