TRISCENIA, nov. gen. Spicule lanceolatis, acuminatz, muticz, pedicellate. Glu- 
m:e, inferior membranacea, superior duplo major, cum flore neutro univalvi herbacea 
eique subzqualis. Flos fertilis solitarius, membranaceus, non induratus, inclusus: 
palea inferior superiorem binerviam subzquans. Lodicule minute. Stamina 93, an- 
therz loculis subdistinctis. Stigmata supra medium florem emersa. Caryopsis libera, 
oblonga; embryone minuto. — Gramen csespitosum, habitu JFestucee ovine ; foliis 
setaceis recurvis subcompressis supra canaliculatis levibus culmum subaphyllum (8 - 18 
poll. longum) ssepe cequantibus, vaginis latiusculis patulis brevibus membranaceis, mar- 
gine ligulari ciliato; spiculis racemosis raris racemisque ramos breves distantes panicule 
erect: anguste continue constituentibus, pedicellis inzqualibus. — Genus a Panico 
flore membranaceo sterilibus glumis (secunda et tertia) tenuiori, embryone minuto, 
habitu distinctum, potius Andropogineis inserendum, et Zoysie aliquid affine, si in hoc 
genere glumam primam Z'iscenie suppressam floremque ad paleam solitariam reduc- 
tum, quandoque etiam nudum, consideramus: sed caryopsis, que Triscenie inter 
Andropogineas Paniceasve anomala fit embryone minuto, in Zoysia et .Leptothrice 
adhuc ignota est.
