560 FLORA NIGRITIANA. 
The Timor plant, which Decaisne identified with Lamarck’s 
Panicum polygonoides, is certainly this species, and a true 
Isachne. The flowers are much smaller than in the more 
common East Indian J. muricata, (Nees. in Herb. Wight). lt 
is doubtful which of them is the original Meneritana. 
l. Panicum brizoides, Linn.— Kunth, Enum. 2. p. 78 2—Cape 
Coast, Vogel; East India. 
The lower glume is not ovate, but broad and truncate, as in 
P. paspaloides, fluitans, and brizeforme, which are all probably 
varieties of one species, common in Tropical Asia and Africa, 
introduced apparently from thence into Tropical America, and 
both as an aquatie and as a cultivated plant, very likely to be 
variable. 
2. Panicum /faleiferum, Trin.—Kunth, Enum. 1. p. 80.—Accra, 
Don. 
3. Panicum Gayanum, Kunth, Enum. 1. p. 79.—On the Quorra 
at Stirling, Vogel; Senegal. 
4. Panicum horizontale, Mey.— Kunth, Enum. 1l. p. 81.— 
Sierra Leone, Vogel, Don; Grand Bassa and Fernando Po, 
Vogel. 
5. Panicum distichophyllum, Trin.—Kunth, Enum. 1. p. 90. 
non N. ab E.—Accra, Don ; at the confluence of the Niger, 
Ansell. 
6. Panicum Numidianum, Lam.—JN. ab E. Gram. Afr. Austr. 
p. 33.—Aboh, Vogel. A single specimen, either belonging 
to this, or a closely allied species. 
7. Panicum maximum, Jacq. (Guinea Grass).—Sierra Leone, 
Aguapim, and on the Quorra, Vogel; St. Thomas, Don. 
This grass, originating from Tropical. Africa, is now exten- 
sively eultivated in East India and South America. In Vogel's 
collection there are two varieties, one growing in moist places, 
and attaining the height of 6 or 8 feet or more, the other about 
2 or 3 feet high, with narrower leaves and smaller flowers, was 
found in dry situations on the Quorra. 
8. Panicum arenarium, Brot.—N. ab E. Gram. Afr, Austr. pP- 
Siang Coast, Don; South Europe, Africa, and East 
ndia.
