Parlatore (Fl. Ital. i. 462) has, under .^l. littoralis, pointed out that two plants 

 have been referred to JE. lavis, Trin., namely, Dactylis brevifolia, Keen., and 

 B. Uttoralis, Willd. The former of these is an Indian species, on which alone 

 Trinius founded the genus, the latter being subsequently referred to it by Steudel 

 (Nora. Ed. II. i. 30) ; but Parlatore was not aware of I>. brevifolia being a species 

 of Eleusine, and that therefore JEluropus, Trin., has no foundation. That this is so 

 is evidenced both by Trinius's citation of Koenig's plant by name as his Icevis, and 

 by his figure of the fruit (Agrost. Fund. t. 12), which is conclusive. It would, 

 however, appear from C. A. Meyer (Verz. Pfl. Cane. 18 (1831) that Trinius may 

 have included both D. brevif>Ua and littoralis under his A. Icevis ; for that author, 

 quoting no doubt from the St. Petersburgh Herbarium, cites laois and villosus as 

 species of Trinius, giving (by error) D. littoralis as the authority for laois, and Poa 

 repens, Bieb., for villosus. Under these circumstances ifappears to me that the best 

 course to adopt, is to retain Mluropus as " Trin. ex parte," for D. littoralis and 

 other plants described by later authors under that generic name. The alternatives 

 are either to coin a new name for the latter, or to adopt for these Calotheca, Spreng. 

 (Syst. i. 342 (1825), which is a mixture of several genera, including ^Uropi, and 

 which name is better avoided, inasmuch as there is an earlier Calotheca (Desv. 1810), 

 likewise made up of several genera of grasses. It remains to say that the synonyms 

 of Meusine brevifolia (see p. 295), and of JEhiropus littoralis and villosus are 

 almost inextricably involved ; and I am far from being satisfied with my attempt to 

 disentangle the first and last of them.
