Diese Art ist aucli von 01. dimidiata, Hochst. und obliquifolia Steud. (beiden aus Surinam) deutlich 

 verschieden; sieh die kurzen Beschreibungen in der Flora Brasil., fasc. 72, p. 325, und in E. G. Steudel, 

 Synopsis plantar. gluinacear., pars I, Graminese (1855), pag. 35, HG. Von beiden finden sich Originalexemplare 

 im Stockholmer Herbarium. Zur Vergleichung mit 01. fasciculata Trin. benntzte ich Exemplare dieser Art von 

 Keönell (n. 239) im Herbar. Regnell. zu Stockholm» 



01. dimidiata differt nervis I. numero 7, spiculse maseulee glumis acutissimis, spiculis femineis in radio 

 umbellse siugulis et glumis longissime caudatis, valvula ovata. 



01. obliquifolia differt nervis I. numero t) — 7, spiculse mascnlae glumis acutiusculis densius pubescentibus 

 (ceterum haec species hal)itu, forma foliorum, indolo spiculse feminese niaxime cum 01. heliconia nostra eongruit). 



Luziola leiocarpa Lindm. n. sp. — Tal'. VIII, A. 



Species Luziolae peruviance Pers. plurimis notis persimilis, differt oinnibus partibus 

 minoribus et caryopsi minuta, lsevi, non striata.
