198 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
top; panicle 25 cm. long; rays slender, in twos, the longest 12 cm. long, very 
scabrous, naked for half its length; spikelets 10 to 12 mm. long, 5-flowered: 
glumes firm, lanceolate, acute, minutely scabrid near the tip, obscurely veined, 
the lower 5 mm., the upper 6 mm. long; lemmas firm, thickish, very obscurely 
veined, acute, purplish near the tip, 7 mm. long; palea slightly exceeding the 
lemma. 
There are no specimens in the National Herbarium that can be referred 
to this species. 
Festuca tolucensis H. B. K. Nov. Gen. & Sp. 1: 153. 1816. 
In Contributions from the U. 8. National Herbarium, volume 107, the treat- 
ment of this species and its supposedly near allies F. multiculmis Steud? and 
F. aequipaleata Fourn.’, was admittedly unsatisfactory. The types of all three 
are in the herbarium of the Muséum d’Histoire Naturelle at Paris. Festuca 
tolucensis, aS shown by more abundant recently collected material, is rather 
variable, especially in the size of the spikelets and the development of the awns. 
Festuca multicuimis Steud. must be regarded as a synonym, as the type (Heller 
306, Mount Toluca) is identical with the type of F. tolucensis from the same 
mountain. Lestuca aequipaleata Fourn. differs only in the tendency of the 
spikelets to be smaller and in the unawned or. very short-awned lemmas. On 
some specimens both awned and awnless lemmas occur, and other specimens 
show complete intergradation to F. folucensis. It is therefore best considered 
a subspecies.* 
Festuca texana Steud. Syn. Pl. Glum. 1: 310. 1854. 
The type is preserved in Steudel’s herbarium in the Muséum d’Histoire 
Naturelle, Paris. It was collected by Drummond (no. 387) in Texas, at San 
Felipe, as indicated by the specimen at Kew. The plant is Leptochloa fascicu- 
laris (Lam.) A. Gray. 
Festuca pseudoduriuscula Steud. Syn. Pl. Glum. 1: 312. 1854. 
The type of this, Drummond’s no. 389 from Texas, is also in Paris. It is 
Festuca obtusa Spreng., as is also Drummond's no. 398, indicated by Steudel as 
a variety but not named in publication. According to the specimens at Kew, 
nos. 389 and 398 are both from San Felipe, Texas. 
Festuca glabra Spreng. Syst. Veg. 1: 358. 1824. 
The original specimen of this is in the Kénigliches Botanisches Museum, 
Dahlem, Berlin, and is labeled “ Seacoast, Long Island, Nuttall.” It is the ordi- 
nary Atlantic coast form of Festuca rubra L.
