more or less kneed or flexuous, hairy downwards. Pedicelled spike-

The author places this near Andropogon confinis, Hochst. The description 
points unmistakably to Hyparrhenia Lecomtei and its immediate allies. The 
passages above put between inverted commas should probably read “ revolute, 
hairy on the lower side ” and “ midrib stout, impressed on the upper side.” 
43a. DYBOWSKIA, Stapf. 
Spikelets 2-nate, or the terminal ternate, inserted on the short 
more or less fragile rhachis of paired racemes, terminating the culms 
and branches, those of the terminal trio differing in sex and shape, 
one of them sessile, the others pedicelled, those of the pairs below 
it homogamous and subsessile, surrounding it like an involucre ; 
raceme-pairs supported by a spatheole and collected in 1 or 2 terminal 
or subterminal tiers ; the fertile spikelet on maturity falling with the 
contiguous pedicels ; the homogamous pairs tardily separating 
afterwards, their adjacent joints entering into the formation of the 
raceme-base, very short, stout, eciliate, obliquely truncate and 
tardily disarticulating ; pedicels of the trio slender, filiform, ciliate, 
obliquely truncate, of the homogamous pair similar to the joints if 
not slightly longer, not disarticulating. Florets 2, lower reduced 
to an empty valve, upper $ in the terminal sessile spikelet, in 
those of the homogamous pairs and in the pedicelled spikelets. 
Fertile spikelets slightly flattened dorsally with broad rounded 
sides, awned ; callus long and pungent, bearded. Glumes equal, 
the lower coriaceous with a very short broad sightly depressed 
beak, margins involute almost up to the beak, then indexed from 
the very short keels, the upper rounded on the back to near the 
obscurely keeled tip, 3-nerved. Valves ciliate, of the lower floret 
hyaline, 2-nerved, of the upper very short, stipitiform, passing 
between two obtuse small hyaline teeth into a coarse kneed hirtellous 
awn. Valvule small, hyaline, nerveless. Lodicules 2, small, glabrous. 
Stamens 3. Stigmas laterally exserted ; styles terminal. Ovary 
oblong, glabrous. Grain unknown. Pedicelled spikelets (of the 
terminal trio) very acute, involute, very finely keeled upwards. 
Valves of both florets developed, much shorter than the glumes. 
Homogamous spikelets very large, equalling or slightly exceeding 
the fertile, similar to the terminal pedicelled but dorsally more 
compressed and flattened. — Annual. Spatheoles very large, boat- 
shaped, the short peduncle and the base of the stout short con- 
tiguous raceme-pairs permanently enclosed in them. 
Species 1, endemic. 
The affinity of Dyhowskia is with the Involucratae series of Hyparrhenia ; 
but the excessive development of most parts of the inflorescence and the very
