branches distantly verticillate along the main rhachis. It was 
first received from the Jardin des Plantes at Paris, where it had 
been raised from seeds brought from China by the Pöre David; 
but it has since turned up among Shearer's Kiu-Kiang plants. 
7. Mers, Beauv. (Zristegis, Nees, Suardia, Schrank), is a 
single Brazilian species, Nees's original type of the tribe. It is 
very near Arundinella, but remarkable for the long slender awn 
of the third empty glume, whilst the flowering glume is short, 
without any awn. Doell has reduced the genus to a section of 
Panicum, a view in which I can by no means concur. 
8. TniscENTA, Griseb., is a single Cuban species unknown to 
me, but from the author's description it must be very near to the 
following. 9. AnTHnoPocoN, Nees, a single Brazilian species, 
well described and figured by Kunth. So also is 10. REYNAUDIA, 
Kunth, a single West-Indian species allied to Arthropogon; but 
the awn, longest on the lowest glume, is gradually shortened and 
reduced to a point on the flowering one, and there is no palea: 
there are, however, four lodicules, a condition so unusual in 
Graminez, that we might be tempted to consider the lowest pair 
of lodieules, though close upon the others, as being in fact a 
bipartite palea. 
11. RHYNCHELYTRUM, Hochst., two or three tropical African 
species, which appear to form a fairly distinct genus allied to Arun- 
dinella, but approaching nearer to the Andropogonee in the long 
hairs of the lower glumes. The generic name was originally Nees's, 
who applied it to a South-African plant of Drége’s, which proves to 
be scarcely even a variety of the Panicum (Tricholena) roseum of 
that country. Hochstetter and Steudel totally misunderstood 
Nees’s genus when they added to it their R. grandiflorum and R. 
ruficomum, which may now, however, retain those names, Nees's 
genus being suppressed. 
12. THYSANOLENA, Nees( Myriachata, Zoll. and Mor.), is a single 
tropical Asiatic species, a very tall grass with long broad leaves 
and a very large full panicle, with innumerable minute spikelets 
in dense clusters along its long erowded branches. The flowering 
glumes are more or less covered with rather long hairs; but these 
hairs are so closely appressed and covered by the empty glumes 
that Steudel could not see them, and published a supposed second 
species as being destitute of them. Trinius figured the plant as a 
Panicum ; by other early Indian botanists it was referred to 
Agrostis.
