In the present paper the notes upon two species of grasses have been 
furnished by Mrs. Agnes Chase, of the U. 8. Department of Agricul- 
ture, and the description of a new species of Piper by Dr. William 
Trelease of the University of Illinois. 
Paspalum botteri (Fourn.) Chase 
Dimorphostachys botteri Fourn. Mex. Pl. 2: 14. 1886. Based on Bottert 
118, collected at Orizaba, Mexico. The specimen was examined in the Paris 
Herbarium. This is the species described as Paspalum macrophyllum 
H. B. K. by Nash.2. The type of that species, also in the Paris Herbarium, 
was likewise examined, and is found to belong to a different group, not to 
that of P. botteri and its allies (the genus Dimorphostachys of Fournier) in 
which the first glume is developed in at least one of each pair of spikelets. 
Chase in Hitchcock’s Mexican Grasses* misapplied the name Paspalum 
planifoltwm Fourn. to this species. That species is based on a Virlet speci- 
men (without number) from San Luis Potosi, Mexico, and Miiller 2062 
‘in herb. Petrop.”’ The Virlet specimen was examined in the Paris Her- 
barium and is found to be the same as P. publiflorum Rupr. Miiller 2062 in 
St. Petersburg Herbarium has not been examined. This collection in the 
Kew Herbarium is P. ividwm Trin.

Syntherisma fiebrigii (Hack.) Chase 
Panicum fiebrigii Hack. Rep. Sp. Nov. Fedde 8: 46. 1910. Based on 
Fiebrig 5371 and 5375 from northern Paraguay, ‘“‘in herb. Hassler.” These 
two specimens, named in Hackel’s script, were examined in the Hassler 
collection in the herbarium of the Jardin de Botanique, Geneva. 
SALVADOR: San Salvador, Calderén 1158. 
Piper incanum Trelease, sp. nov. 
A shrub, 1.5 or in richer soil 3-5 m. high, nodose; flowering internodes 
moderately slender and short (4X40 mm.), gray-subtomentose; leaves 
elliptic or subobovate, acuminate, inequilaterally subcordulate, rather small 
(5-6 12-14 or as much as 8X16 em.), pinnately nerved from below the 
middle, the nerves 5 or 6X2, gradually approximated downward, at length 
bullulate, somewhat thinly appressed-hispid on both faces and gray beneath; 
petiole rather short (8X2 mm.) and winged at base, or on the more equi- 
laterally truncate-cordulate lower leaves twice as long and winged to or 
beyond the middle; spikes opposite the leaves, gray-mucronate, in fruit 
380 mm.; bracts roundish-subpeltate, gray-ciliate; peduncle gray-hairy, 
12 mm. long; berries obconic, glabrous; stigmas 3, sessile.
