2. LEUCOPHYLLUM H. & B. 



Spreading shrubs, with scurfy-pubescent foliage. Leaves alternate, sometimes clustered : 

 blades relatively small, flat, entire. Flowers on solitary axillary pedicels. Calyx-lobes 

 rather valvate. Corolla violet-purple : tube funnelform or broadly campanulate ; lobes 5, 

 rounded, spreading, the 2 upper ones exterior. Stamens 4, included. Styles united. 

 Ovules numerous. Capsule 2-valved. Seeds strongly wrinkled. 



Leaf-blades silvery canescent : corolla funnelform ; limb 10-12 mm. broad. 1. L. minus. 



Leaf-blades tomentose : corolla campanulate ; 1 mb 20-25 mm. broad. 2. L. Texanum. 



1. Leucophyllum minus A. Gray. A shrub 3-7 dm. tall. Leaf-blades spatulate 

 or obovate -spatulate, usually 1 cm. long or less, blunt or slightly apiculate, silvery canes- 

 cent, conspicuously narrowed into petiole-like bases : outer calyx-lobes linear or nearly so, 

 3-4.5 mm. long : corolla sparingly pubescent within : capsules about 4 mm, high. 



In dry soil, southern and western Texas. Spring and summer. 



2. Leucophyllum Texanum Benth. A shrub 6-25 dm. tall. Leaf-blades oblong, 

 elliptic or obovate, 1-2 cm. long, apiculate pale-tomentose with very densely set hairs, 

 gradually or rather abruptly narrowed to the manifestly sessile base : outer calyx -lobes 

 oblong to oblong-lanceolate, 5-6 mm. long : corolla villous within : capsules 4-5 mm. high 



In dry soil, southern Texas and adjacent Mexico. Spring and summer. 



3. KfCKXIA Dumort. 



Annual herbs, with spreading or creeping stems. Leaves alternate : blades flat, entire, 

 toothed or lobed. Flowers on solitary axillary pedicels. Sepals 5, slightly united. Cor- 

 olla white, yellow or variegated, irregular, 2-lipped : tube spurred, the throat closed by a 

 palet, the lips lobed. Stamens 4, included. Styles united. Ovules numerous. Capsule 

 ovoid to subglobose, opening by 1 or 2 terminal slits, pores or valves. Seeds tubercled or 

 merely roughened. 



1. Kickxia Elatine (L. ) Dumort. Foliage villous or hirsute. Stems branched at 

 the base ; branches spreading or prostrate, 1-5 dm. long : leaf-blades hastate, or ovate to 

 elliptic near the ends of the branches, 1-2.5 cm. long, short-petioled : pedicels filiform, 

 surpassing the subtending leaf-like bracts : calyx densely pubescent ; lobes lanceolate, 1.5- 

 2.5mm. long, acuminate: corolla 5-6 mm. long, minutely pubescent ; lobes rounded, the 

 spur about as long as the lower lip : capsules 3-4 mm. in diameter.
