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 Texànum 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. KÍCEXIA 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 Blátine (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- 
2.5 mm. 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.
