ANISANTHERINA Pennell, gen. nov. 
Stem erect, 1-4 dm, tall, branching, hirsute-pubescent with 
reflexed-spreading dark-jointed hairs. Leaves opposite, sessile, 
linear, sparingly minutely lobed, scabro-pubescent above, 4—6.5 
cm. long. Pedicels 25-35 (-45) mm. long, bibracteolate about 
the middle. Calyx of 5 united sepals, the lobes shorter than the 
tube. Corolla 12-14 mm. long, pinkish (not seen fresh), the lobes 
much shorter than the tube, the two posterior united only at base; 
within glabrous proximally, but pubescent over the bases of the 
posterior lobes. Filaments 4, lanate distally, the posterior pair 
shorter; anther-sacs unequal, the outer one smaller, glabrous. 
Style glabrous. Stigma linear, consisting of two lines, one down 
each side of style-apex. Capsule 7-8 mm. long, globose with a 
mucro, glabrous, loculicidal and septicidal. Seeds 0.6-0.8 mm. 
long, oblong-linear, reticulate, dark-brown, wingless. [Name 
from avoos, unequal, and avypa, anther.] 
This monotypic genus resembles Agalinis, which however has 
both anther-sacs alike, pedicels not bracteolate, and seeds wider.
