DIGITARI A Heister 
DIGITARI A SANGUINALIS (Linn.) Scop. FI. Carn. ed. 2 1 (1772) 52. 
Panicum sanguinale Linn. Sp. PI. (1753) 57. 
G. E. S. 220, apparently the form described by Thwaites as the variety 
australis. 
Warmer parts of both hemispheres, variable. 
DIGITARIA CILIARIS (Retz.) Pers. Syn. 1 (1805) 85. 
Panicum ciliare Retz. Obs. 4 (1786) 16. 
G. E. S. 21 4. 
Widely distributed in the warmer parts of both hemispheres, frequently 
considered merely a variety of the preceding. 
DIGITARIA STRICTA Gaudich. Bot. Freyc. Voy. (1826) 409, non Roth 
(1821). 
Panicum gaudichaudii Kunth. Rev. Gram. (1830) 385, t. 106; Safford 346. 
The type of this was from Guam, and it is not otherwise known. From 
the descriptions available I suspect that it is but a form of some one of 
the closely allied species, D. consanguinea Gaudich., D. microbachne Presl, 
etc., and have accordingly refrained from transferring Kunth’s specific 
name, the valid one of the species, to Digitaria. 
DIGITARIA MARIANNENSIS sp. nov. 
Planta parva, prostrata, ramosa, ciliato-pilosa ; foliis anguste 
lanceolatis, 1 ad 2 cm longis, numerosis ; ramis floriferis erectis, 
circiter 5 cm altis; spicis binis, 1.5 ad 2.5 cm longis, rhachibus 
undulatis; spiculis biseriatis, sessilibus, oblongo-lanceolatis, 2.5 
mm longis, glumis 1 et 2 obsoletis, 3 plus minusve pilosis, circiter 
9-nerviis, margine inflexis, dense ciliato-pilosis, 4 (floriferis) 
anguste lanceolatis, glabris, laevis, acuminatis. 
A small, prostrate, branched, rather densely ciliate-pilose plant, 
the stems very slender, rooting at the nodes and sending up 
erect, short, simple, flowering branches about 5 cm in length, 
the creeping stems up to 40 to 50 cm in length, their internodes 
2.5 cm long or less, glabrous. Sheaths ciliate-pilose, rather loose, 
mostly shorter than the internodes ; ligules membranaceous, 
truncate, about 0.5 mm long; leaf-blades narrowly lanceolate, 1 
to 2 cm long, 2.5 to 4 mm wide, acuminate, base somewhat 
narrowed, " both surfaces ciliate-pilose with long white hairs. 
Spikes in pairs, somewhat exserted, slightly pubescent, 1.5 to 
2.5 cm long, few-flowered, usually appressed to each other, their 
rachises undulate, 0.5 mm wide. Spikelets 2-seriate, sessile, 
closely appressed to the rachis, alternate in the undulations, 
oblong-lanceolate, 2.5 mm long. First and second glumes en- 
tirely obsolete. Third glume (first and only empty glume for 
this species) oblong-elliptic, somewhat pilose, obtuse or somewhat 
acute, about 2.2 mm long, 1 mm wide, 9- to 10-nerved, the
