116 VEBBENACEAE. 



1. L. Camara L. Shrub with armed branches, 10-15 dm. tall : leaf -blades ovate 

 to oblong-ovate, 2-7 cm. long: corolla yellow to orange; limb 6-8 mm. high. 

 Two forms of this species occur in Florida: one with acuminate leaf -blades, 

 derived from plants commonly in cultivation apparently from the West Indies, 

 the other a native plant with obtuse, relatively coarser-toothed leaf -blades. 



Roadsides, waste places, and cultivated grounds, n. Fla. and the pen. The 

 native plant occurs in pinelands, hammocks and about swamps. (Cont., W. I.) 



2. L. aculeata L. Shrub with copiously and rigidly armed branches, 2.5 dm. 

 tall or less: leaf -blades ovate, often broadly so, 3-6 cm. long: corolla yellow 

 to purple; limb 7-9 mm. high. 



Pinelands, cultivated grounds, and roadsides, pen. Fla. Nat. of the W. I. 



3. L. depressa Small. Shrub with unarmed prostrate branches, 2-11 dm. long: 

 leaf -blades ovate to elliptic, 1-3.5 em. long: spikes less than 2.5 cm. wide: 

 corolla-tube 5-6 mm. long: stone of the drupe globose, 2-3 mm. long, scarcely 

 beaked. 



Pinelands, E. Keys. (Endemic.) 



3. L. ovatifolia Britton. Shrub 2 m. tall or less: leaf-blades ovate, 3-7 cm. 

 long, crenate-serrate : spikes over 2.5 cm. wide: corolla-tube 9-10 mm. long: 

 stone of the drupe ovoid, about 5 mm. long, beaked. 

 Hammocks, s. pen. Fla. (W. I.) 



5. L. Sellowiana Link & Otto. Shrub 3-18 dm. tall, with tomentulose foliage : 

 leaf-blades ovate, oval, or elliptic-ovate, 1-3 cm. long, abruptly narrowed or 

 truncate at the base : corolla magenta or lilac ; tube puberulent ; limb 8-10 mm. 

 high, the lower lobe much longer than the others. POLECAT-GERANIUM. 



Thickets, pinelands, and waste places, pen. Fla. Nat. of Trop. Am. (W. I.) 



6. L. involucrata L. Shrub 4-17 dm. tall, with puberulent or tomentulose 

 foliage: leaf -blades oval, obovate, to suborbicular, 1-3 cm. long, usually cuneate 

 at the base : outer bracts of the involucre 4-7 mm. long, ciliolate : calyx becom- 

 ing 1.5 mm. long: corolla white or pale-purple; tube 2-4 mm. long; limb 2-4 

 mm. high. 



Hammocks, pinelands, and sand-dunes, s. pen. Fla. and the F. Keys. (W. I.) 



7. L. odorata L. Similar to L. involucrata in habit: leaves similar but com- 

 monly larger: bracts of the involucre narrower, the outer lanceolate or oblong- 

 lanceolate: flowers often smaller. 



Hammocks and sand-dunes, s. pen. Fla. and the F. Keys. (W. I.) 



3. CITHAREXYIiUM L. Shrubs or trees, sometimes spiny. Leaf -blades 

 mainly entire. Flowers in clusters or long spikes. Calyx obscurely 5-lobed. 

 Corolla mainly white: tube straight or nearly so: limb slightly oblique, nearly 

 equally 5-lobed. Staminodium present. Stigma 2-lobed. Nutlets 2. 



1. C. fruticosum L. Shrub or small tree, with softly pubescent twigs: leaves 

 5-15 cm. long; blades elliptic, oblong, or oblong-obovate, veiny: flowers in 

 spikes or racemes: fruits 9-10 mm. in diameter. FIDDLEWOOD. 



Hammocks and pinelands, lower half of the e. coast of Fla., the E. Keys and F. 

 Keys. (W. I.) 



4. DURANTA L. Shrubs or trees, often spine-armed. Leaf -blades entire 

 or toothed. Flowers in racemes. Calyx more or less prominently but minutely 

 5-lobed. Corolla salverform or funnelform: tube mainly curved: limb slightly 

 unequally 5-lobed. Staminodium mostly obsolete. Stigma 4-lobed. Nutlets 4. 



1. D. repens L. Shrub or small tree : leaf -blades ovate-elliptic, oval or obovate, 

 1.5-5 cm. long: racemes 5-15 cm. long, recurving: calyx 3-4 mm. long, angled:
