Retz and Wahlenberg attribute to this a single purely male spike, remote female ones, and mention that 
the whole plant is a span long : our species is obviously considerably larger, the female spikes are not re- 
markably remote, and the mixture of female flowers on the terminal spikes may be the effect of accident. 
On the other hand, the description of the fruit, of the scales, of the sheaths to the bractem, of the bractem 
themselves, and especially their being about equal in length to the spikes, the number of stigmas, and the 
smoothness of the culm, are the same in both. We searcely entertain a doubt respecting their identity.]

[This varies with the glume 3-7-nerved and the spikes either in pairs or several, or 3-nerved, and then the 
spikes are usually in pairs : in the Chinese specimens ( Vachell, “ Z.”) referred here by us, the glumes are 
3-nerved; there are several (3-5) spikes, and the spikes are more spreading than usual; the plaits on the 
glumes, which are rather small for this species, are not very conspicuous. It is the only species, we believe, 
from the East, with orbicular spikelets placed in two rows on the rachis.]

* The terms used by Professor Nees v. Esenbeck being not quite the same as those employed by Trinius, the follow-

may be acceptable: — 
“1. As to the distribution of the spikelets. The words homogamous (viz. spikelets) and heterogamous signify the dis- 
tribution of the sexes in different spikelets on the same individual. They are called homogamous if there be no differ- 
ence in this respect between any of the spikelets of the same individual, as in JBromus: — heterogamous, if the arrangement 
of the sexes be different in different spikelets from the same root, as in Andropogon. Dioecious signifies that there are some 
spikelets conformably male (whether provided with an accessory neuter floret or not) on one individual, and conformably 
female on another, as in Gynetium : and monoecious, that male and female spikelets (whether or not they be accompanied 
by a neuter floret) are distributed apart from each other, but on the same individual, as in Zea. 
“ As to composition. The terms hemiologamous, hemigamous, and polygamous, serve to indicate the distribution of the 
sexes among the different florets of the same spikelet. A spikelet is called polygamous, if one, of the two florets which it 
contains be unisexual, and the other bisexual, as in Spodiopogon, and several Panica. A hemiologamous spikelet is 
that in which one of the two florets is neuter, and the other bisexual, as in several species of Panieum. Hemigamous 
signifies that a spikelet is composed of one neuter floret and another unisexual, whether male or female, as in Ischce- 
mum. Spikelets are also called Monoecious in composition, where one of the two florets is male and the other female.” —
