cystolithis numerosis instructis, 3 ad 7 cm longis, sursum an- 
gustatis, apice obtuse acuminatis, basi acutis ad subobtusis, 
nervis utrinque 4 vel 5; cymis paucifloris, bracteis inferioribus

seminibus 8. 
A slender annual herb 30 to 40 em high, the lower portions 
of the stems often decumbent, the branches, leaves, and bracts 
with numerous cystoliths, the branches at most 1.5 mm in diam- 
eter, the very young branchlets sparingly appressed-pubescent. 
Leaves lanceolate, chartaceous, 3 to 7 em long, 7 to 15 mm 
wide, dark olivaceous when dry, entire or very obscurely undulate, 
narrowed upward to the blunt-acuminate apex, the base acute 
to subobtuse; lateral nerves 4 or 5 on each side of the midrib, 
slender, obscure; petioles 3 to 10 mm long. Cymes terminal, 
few-flowered, the bracts subtending the pedicels narrow, oblong 
to lanceolate, at most 2 to 3 mm long, the two foliaceous bracts 
subtending the flowers ovate to oblong-ovate, acute, the base 
broadly rounded and distinctly cordate, 12 to 15 mm long, 6 to 
~ 10 mm wide, sessile, the bracteoles narrowly lanceolate, acu- 
minate, 4 to 6 mm long. Sepals narrowly lanceolate, acuminate, 
slightly pubescent, 4 mm long. Corolla pale purplish, about 
2.2 cm long, the tube slender, 12 mm long and slightly ciliate

Anthers linear-oblong, 3.5 to 4 mm long, the upper cell slightly 
overlapping the upper portion of the lower one. Capsules about 
10 mm long, sparingly hirsute, the basal narrowed portion 5mm 
long, the seed-bearing part oblong, somewhat acuminate, about
