Diplachne and leptochloa (Poaceae) in North America
Tóm tắt
Most North American botanists includeDiplachne inLeptochloa but good evidence for this treatment has never been provided. The diagnostic characters of these two closely related genera of the tribe Eragrosteae are presented and the seven species ofDiplachne and six ofLeptochloa occurring in America north of Mexico are distinguished. Three new combinations are made inDiplachne:D. sect. Ipnum, D. panicoides andD. monticola and the generic disposition of all the Central and North American species noted.
