PLATYSTEMON AND ITS ALLIES. 141 
Concerning the somewhat more recently established genus 
Meconella, which Bentham declined to recognize as a genus, 
referring the species to Platystigma, I remarked in my first 
treatment of the group, that it has better claims to generic 
rank than has Platystigma’; and I here propose its restoration. 
MECONELLA, Nuttall. 
Slender upright branching annuals, with small white 
flowers on long filiform peduncles. Herbage glabrous and 
glaucous, only the small sepals sparsely aculeolate at sum- 
mit. Leaves partly in a basal and rosulate tuft, partly 
cauline and opposite in whorls of three. Sepals petals 
6; the inner 3 always narrower. Stamens normally 
6,8 or 12; when 12 the 6 outer with much shorter fila- 
ments; the filaments seldom or never obviously dilated, 
never petaloid. Carpels 3, long, slender, spirally twisted. 
Anthers short, ovate or oval, adnate 
Corollas & inch broad

s 8, the 4 outer shorter 2. M. octandra. 
Corollas x to 4 inch broad 
Stamens 12, the 6 outer shorter. 
Filaments all filiform 3. M. Californica. 
Some inner filaments dilated from base to middle and 
toothed 4. M. collina. 
Anthers linear, nearly or quite as long as the gee these 6 only, 
uniserial, equal; corolla % inch broad. 5. M. denticulata.
