508 GRAMINEZ. 
8. Pennisetum flavescens, Presl, Relig. Henk. i. p. 49. 
Mexico (Henke). 
A doubtful plant, perhaps not different from P. setoswm. Fournier did not see it. 
4. Pennisetum humboldtianum, Hemsl. 
Gymnothriz crinita, H. B. K. Nov. Gen. et Sp. i. p. 112; Kunth, Enum. Pl. i. p. 159; Fourn. Mex. 
Pl. Enum., Gram. p. 47. 
Mexico, on the shores of Lake Cuisco near la Puerta de Andaracuas, and near Santa 
Rosa at 5400 feet (Humboldt & Bonpland). 
Fournier, rightly or wrongly, refers several specimens in recent collections to this 
species. See remarks under P. mexicanum. 
5. Pennisetum karwinskii, Schrad. in Linnea, xii. p. 43; Fourn. Mex. Pl. 
Enum., Gram. p. 49. 
Mexico (Karwinskt). 
Fournier states that this was not found among Karwinski’s plants of the St. Peters- 
burg Herbarium. 
6. Pennisetum mexicanum, Hemal. 
Gymnothriz mexicana et G. grisebachiana, Fourn. Mex. Pl. Enum., Gram. p. 48. — 
SoutH Mexico, Orizaba (Bourgeau, 3139; Miller, 2015, 2067), Papantla (Liebmann). 
Hb. Kew. 
Fournier refers Miiller’s 2067 to Gymnothria crinita, but the Kew specimen bearing 
this number is the same as 2015 and as Bourgeau’s 3139. On the other hand, the 
Pennisetum setosum of Bentham’s ‘ Plantes Hartwegiane,’ which Fournier also refers to 
Gymnothria crinita, is certainly different from Miiller’s plant, though it may be true 
crinita. It is very probable that Fournier had different species under the numbers in 
question. P. mexicanum is perhaps hardly specifically different from P. complanatum. 
7. Pennisetum multiflorum, Fourn. Mex. Pl. Enum., Gram. p. 49. 
Fournier merely describes the inflorescence and flowers of this, and adds “ con- 
fusum cum ceteris.” 
8. Pennisetum nervosum, Trin. ; Steud. Gram. p. 102. 
Gymnothrix nervosa, Nees, Agrostol. Bras. p. 277; Doll in Mart. Fl. Bras. i. 2, p. 8302; Fourn. 
Mex. Pl. Enum., Gram. p. 47. 
Sovura Mexico, Tampico (“ herb. Uzac” ex Fournier).—BRAZIL. 
9. Pennisetum nicaraguense, Fourn. in Bull. Soc. Bot. France, xxvii. p. 293. 
Nicaracua, around Granada (Lévy, 1304). |
