528 Evans: A NEW LEJEUNEA 
tropical and subtropical America. Both species are somewhat 
larger than L. minutifolia, the leaves being often 0.7 mm. in length, 
but they agree with it in inflorescence and in having small or- 
bicular underleaves. In both species, however, the lobules are 
frequently inflated and conform closely to the usual Lejeunea type. 
L. floridana is further distinguished by its much larger perichaetial 
bracts (often 0.8 mm. in length), by its more shortly bifid under- 
leaves and bracteole, and by the crenulate keels of its perianth, 
projecting upward as horns. In L. glaucescens, the bracts approxi- 
mate those of L. merreifalee in size but the lobules are usually 
distinctly pointed.
