Chase — Notes on Genera of Panicese. II. 3 



dente [H. fluviatilis, which is the same as Panicum vilvoides and H. cam- 

 pestris] floscnlus hermaphroditus glumis et neutro flosculo brevior est 

 mnlto, non vero herbaceus ut in H. myuro, sed subcartilagineus." Pani- 

 cum paludicola Nees, a Hymenachne, and P. striatum Lam., a Sacciolepis, 

 are given among true Panicums. 



Desvaux (1831, Opus. 82) transfers Agrostis monostachya Poir. to Pani- 

 cum, changing the name to P. Hymenachne Desv. He observes that this 

 plant had been confounded with Agrostis [Panicum] myuros, which was 

 very different. 



Kunth (1833, Enum. PL 1: 86) under division 5 includes a miscella- 

 neous group of Sacciolepis, Hymenachne, Eriochloa and other allies, as 

 well as several species of Panicum itself. 



Trinius (1883, Pan. Gen. 165) includes about the same group under his 

 section Virgaria of Panicum. 



Nees (1841, Fl. Afr. Aust. 50.) makes a section Curviflora of Panicum 

 for two species of Sacciolepis. 



Steudel (1854, Syn. PL Glum. 2 :■ 101) includes in the genus Hymen- 

 achne four names referable to Sacciolepis, and two (which are, however, 

 synonyms) to Hymenachne; a seventh species, which is probably a Saccio- 

 lepis, he includes with the mark of doubt. 



Grisebach (1864, Fl. W. I. 553) includes in the genus Hymenachne one 

 species which belongs there and two which belong to Sacciolepis. 



Doell (1877, Mart. Fl. Bras. 2 2 : 231) in the first part of the section 

 Miliaria of Panicum gives seven species, five of which are referable to 

 Sacciolepis, one to Hymenachne, and one probably to Steinchisma. Pani- 

 cum auriculatum, a Hymenachne with ascending, not oppressed, panicle 

 branches, is placed in the second part of the section in which most of the 

 species are true Panicums. It is worthy of note that Doell uses the name 

 Panicum myuros Lam. for the species to which the type really belongs, 

 stating that he saw the specimen in the Paris Museum. Under Panicum 

 amplexicaule Rudge, he straightens out the hitherto confused synonomy 

 of this species. 



Bentham (1878, Flora Australiensis 7: 465) makes a section Myuroidese 

 of Panicum under which he places three species, two of which belong in 

 Sacciolepis and one in Hymenachne. 



Founder (1881, Mex. PL 2: 36) includes eight species in the genus Hy- 

 menachne, two of which are referable to Sacciolepis, three to Hymenachne, 

 and two to Panicum. The remaining species, H. Gouini Fourn., unknown 

 to us, is probably a Hymenachne. 



Hackel (1887, Engler & Prantl. Pfl. Fam. 2' 2 : 35) recognizes Hymen- 

 achne as a section of Panicum with spike-like panicles and slightly indu- 

 rated glumes. No species are mentioned. 



Hooker (1896, Fl. Brit. Ind. 39) places seven species under Hymenachne 

 as a section of Panicum, three of which are referable to Hymenachne and 

 four to Sacciolepis. 



Stapf (1898, Flora Capensis 386) makes a section Vilfoidese for three 

 species referable to Sacciolepis.
