third and even sometimes the fourth from the bottom tolerably wide 

 apart, and all more or less compound at their base, sometimes (though 

 rarely?) simple, their spicules more or less spreading; subterminal 

 spikelets approximate, the terminal crowded, smaller and more pointed 

 than the basal, and simple. Brads subulate, foliaceous, erect, very 

 rough on the margin and keel, with trigonous points, the lowermost 

 bract always much longer than the rest, and generally overtopping the 

 spike, often quite as long as in C. remota, the remaining bracts always 

 as remarkably shorter than in that species, the inferior bracts not 

 reaching the summit of the spike,, those still higher reduced to mere 

 subulate points of their broad, glume-like bases, and below the crowded 

 terminal spikelets scarcely distinguishable from the glumes themselves; 

 in these respects agreeing with C. divulsa, to which, although suffici- 

 ently distinct from both, our present plant and C. remota bear a con- 

 siderable degree of resemblance. Glumes ovate, acute and even 

 mucronate, membranous, at first greenish and silvery, finally pale 

 tawny, and having a broad, tapering, bright green keel, and a central, 

 pellucid, often roughish nerve continued to their apex. Staminate 

 florets in all my specimens apparently few at the base of each of the 

 lower spikelets, often scarcely any, one or two occasionally in the 

 centre or upper part of them ; more numerous in the terminal and 

 subterminal spikelets, which are sometimes wholly staminate or nearly 

 so. Anthers bearded or spinulose at the tips. Styles two, long and 

 tapering. Perigynes substipitate, nearly erect (not spreading), ovate- 

 lanceolate, tapering (not rounded) at base, plane in front, slightly con- 

 vex at the back, with several prominent ribs ; mostly about as long or 

 longer than the glumes, gradually narrowed into the green, rough- 

 edged, rather deeply cloven beak. Nut broadly ovate or ovate-ellip- 

 tical, much compressed, smooth, tapering into a short cylindrical 

 point, on which the persistent style is apparently articulated ; seldom, 

 it would seem from Kunze's observations and my own, perfected. 



The foregoing description will enable any one to judge in what re- 

 spects C. Boenninghauseniana differs from C. axillaris, from which I 

 feel myself at present quite incompetent to disentangle it in figures, 

 description or dried specimens. The plant pronounced to be C. 

 Boenninghauseniana, from Quarr Copse, and described above, has to 

 my eyes little or no resemblance to C. paniculata, if we except its 

 densely cespitose habits of growth, but the figure in E. B. Suppl., and 

 a plant in St. John's garden at Ryde, from Mr. Borrer (from the ori- 

 ginal Hertfordshire station, if I mistake not), do in the darkness of the
