1920] Fernald, —New Digitaria from New Hampshire 103 
come from southern New Hampshire rather than southeastern Massa- 
chusetts is, however, somewhat surprising, although the New Hamp- 
shire stations for Rynchospora Torreyana Gray and Sclerolepis uni- 
flora (Walt.) BSP. are in nearly the same latitude and only thirty to 
thirty-five miles away. The discovery of these three plants indicates 
that the sandy regions of Hillsboro, Merrimack, and eastern Sullivan 
Counties need very careful exploration. 
In organizing the North American material of Digitaria in the 
Gray Herbarium it has been found necessary to make the following 
transfers. 
D. saNGUINALIS (L.) Scop., var. marginata (Link), n. comb. 
D. marginata Link, Enum. Hort. Bot. Berol. i. 102 (1821). Panicum

39 (1894). P. lineare, var. mississippiense Gatt. ex Beal, Grasses 
N. A. ii. 111 (1896). Syntherisma linearis mississippiensis (Gatt.)

inger and by Scribner as common in sections of Tennessee, this char- 
acteristic variety has been collected also in Maryland and Iowa. 
D. Simpsoni (Vasey), n. comb. Panicum sanguinale, var. Simp- 
soni Vasey, Contrib. U. S. Nat. Herb. iii. 25 (1892). P. Simpsoni

Agrost. 12, 154 (1812). Syntherisma paniceum (Swartz) Nash, N. 
A. Fl. xvii. 152 (1912). ^ 
The combination D. panicea Willd. ex. Steud. Nom. ed. 2, pt. 1, 
508 (1840) was published as a pure synonym of Panicum sanguinale 
and therefore has no nomenclatorial status.
