and distinctly auriculate at the base, the auricles often overlapping. 

 The innermost bracts and bracteoles of the female inflorescences 

 are not well developed; the lobes of the bracts, however, are 

 entire and the same thing is true of the lobules (except for the 

 stylus) and of the divisions of the underleaves. None of these parts 

 are canaliculate. The specimens are clearly distinct from F. hians, 

 but it is evident that F. Arecae is in need of further study. It is 

 perhaps worth noting that there is a specimen of Jungerniannia 

 Arecae Spreng. in the Lindenberg herbarium at Vienna, labeled 

 " ab ipso," and presumably a co-type. This specimen is autoicous 

 but lacks perianths and is insufficient to give a clear idea of the 

 species. According to Stephani the range of F. Arecae extends 

 from Mexico to Chile and the plant is common throughout this 

 whole region. 



Among the species with pluriplicate perianths recognized by 

 Stephani the following are autoicous: F. glauca Steph., of Brazil; 

 F. itatiaja Steph., of Brazil; and F. spiniloha Steph,, of Panama 

 and Ecuador. These species are known to the writer from de- 

 scription only and are evidently very close to F. hians. 



In distinguishing F. hians the following characters wiU be found 

 useful: the reddish or purplish pigmentation (not always present), 

 the imbricated leaves and underleaves, the more or less crispate 

 lobes, lobules and underleaves, the strongly arched water-sac ter- 

 minating in a slender point, the variable, oblong appendiculum 

 often with teeth, the minute stylus, the great infrequency of inter- 

 mediate thickenings in the middle of the lobe and their greater 

 frequency elsewhere, the autoicous inflorescence, the crowded, large 

 and highly coalescent bracts and bracteoles, the sharp-pointed 

 and often toothed lobes, lobules and divisions of the bracteoles, 

 the canaliculate lobules and divisions, the long pluriplicate perianth 

 with a long beak, the throat of which is closed by papillae.

 Frullania laxiflora Spruce, Hep. Amaz. et And. 26. 1884. 

 On wood, San Miguel, 6,000 feet, July 24, 1911. 

 In his original description of F. laxiflora Spruce records the 

 typical form of the species from trees and rocks in Ecuador and 

 a variety Crossii from Colombia. Stephani states that the plant 

 grows also in Guatemala and Venezuela. The writer has seen no 

 authentic specimens of the species and bases his determination of 

 the Peruvian material on the full descriptions of Spruce and Stephani.
