cellatis super nodis pilosis suffultis; foliorum vaginis longitudinaliter suleatis, infer- 
ioribus scabrido-pubescentibus, superiore glandulifero; ligula pilosa; lamina lineari, 
apice attenuata, glabra ; paniculee ramis ascendentibus vel patentibus, velut ramulis 
pedicellisque glanduliferis ; spiculis ovalibus, subcompressis, gluma 1™ brevi, ovata, 
3-pectinata, purpurea, sublinea longa, 2* lata, truncata, 5-nervia, pectinata, 5-dentata, 
3" ovali-oblonga apice irregulariter dentata, 7-nervia, margine purpurea; florifera 
quam preecedens subbreviore, ovali, apice subobtusa et dorso sparse ciliolata; palea 
quam gluma includente breviore, sub apice sparse pilosa. 
The slender leafy culms are longitudinally striate, 12-21 in. long, and bear a few 
long-stalked capitate hairs, evidently glandular, below the pilose nodes. The leaf-sheaths 
are longitudinally ridged, the lower ones scabrido-pubescent, while the uppermost bears 
the stalked glands in the depressions between the ridges; the ligule is represented by a 
row of pilose hairs at the mouth of the sheath; the linear blade has a tapering, some- 
what cuspidate apex, is longitudinally striate with inconspicuous venation, 3-4 in. long, 
13 lines broad, in the radical leafy shoots often with completely involute margin. The 
inflorescence is a panicle, with branches ascending or spreading, and giving an ovate 
general outline 3-5 in. long by 2-3 in. broad; the axis, branches, and pedicels bear the 
characteristic glands, which are easily rubbed off the dry plant. The oval subcompressed 
spikelets are 1? lines long. The short outer glume is $ line long, consisting in the upper 
part of three teeth, of which the middle is the longest; the second is purple like the first, 
but larger, 14 lines long, and 5-nerved, or with a shorter 6th nerve not reaching the top, 
with 5 apical teeth ; the third is oval oblong, 1$ lines long, 7-nerved, with purplish edges 
and an irregularly toothed apex; the 4th or flowering glume is very slightly shorter than 
the third, oval, flattened dorsally, with involute edges firmly enclosing the pale and flower : 
it is coriaceous with a hyaline margin, the upper third purple, the rest greenish, sparsely 
ciliolate on the back beneath the subobtuse apex. The pale is slightly shorter than the 
flowering glume, 14 lines long, flattened dorsally, with involute margin, subcoriaceous 
with hyaline edges, glabrous except for a few hairs near the acute apex. The stigmas 
are plumose. Fruit not seen.

This grass is of interest from a biological standpoint owing to the long-stalked glands, 
which must be of importance in the life of the plant, while from a systematic point of 
view its pectinate glumes separate it from all other species of the genus Panicum. The 
latter character I was inclined to consider of generic value, but Prof. E. Hackel, whom I 
consulted, thinks the plant “a true Panicum, but somewhat anomalous in the genus on 
account of its toothed glumes.” He also reminds me that, while no Panicum is known 
as yet which offers this character, a similar case occurs in the genus Muehlenbergia, 
where M. clomena, M. gracilis, and others have the second empty glume three-toothed, 
a fact which led Beauvois and Nuttall to separate them as distinct genera; modern 
authors, however, including Bentham, have reunited them with Muehlenbergia. 
P. pectinatum falls in the section Hupanicum, its otherwise normal spikelets, with
