Pseudopoa, C. Koch in Linnza, xxi. 409, includit P. persicazi, Poir., cum. speciebus 2 Asiatieis ei 
affinibus, Annuze sunt, habitu gracili NepAelocAloe, cui adjunxit Grisebach etsi characteribus minime 
conveniant. C. Koch sectionem in F'estuca includit ob caryopsin palez adhzerentem, quod tamen 
observatur in Pois pluribus genuinis eg. im P. Billardieri, Steud., ssepeque in ipsa P. pratensi ; 
eharacteres czeteri Pseudopoe omnino Poe. 
Lrvcoroa, Griseb. in Ledob. Fl. Ross. iv. 383, est P. albida, ''urcz., species spiculis solito majori- 
bus, glumis subscarioso-nitentibus, quod tamen plus minus observatur in aliis speciebus, e.g. in 
P. chilensi affinibusque ex America australi extratropica. 
Dioicopoa, E. Desv. in €. Gay, Fl. Chil. vi. 418 (Dispar, Dadll), continet P. chilensem, Trin., 
P. lanugi Poir, affinesque ex Ameriea eustrali extratropica, spieulis sepius abortu dioicis.
