ON THE AWNS OF NEPAUL BARLEY. 37 
ordinary circumstances these hairs are directed forward, but in many 
instances (fig. 17, 18) they become reflexed throughout the space 
immediately beneath the base of the bud (a) and the spot where 
the basial leaf (5) ceases to be attached to the awn. This is a pretty 
constant phenomenon wherever the bud has become well developed; 
and it appears very clearly to indicate the great extent to which the 
forces in relation to its own ** axis of development" have exerted their 
influence over parts which otherwise would have been modified by those 
forces only which are in relation to the “ axis of development " of the 
awn. 
Among the examples just given, we have (at fig. 19) very distinct 
traces of the formation of several rudimentary appendages round the 
axis of the bud. A rudimentary scale, stamen, and ovaries, fig. 20, 
are well marked, and indicate the fact that the bud is strictly floral in 
its character, and is composed of several internodes. We may now 
readily anticipate the occasional exhibition of a still more complete 
development of floral appendages upon it, and such are often found to 
be numerous and well marked. The scales are often more or less mem- 
branous and closely resemble the ordinary glume and paleæ of regularly 
formed spikelets. Those which belong exclusively to the bud are easily 
_ distinguishable from the * wings," which we have considered to result 
from some joint influence of both axes of development. In fig. 23 
is represented the most highly developed state I have noticed of the 
stamens. In this case, distinct traces of pollen occurred, though the 
ains did not contain granules. Some of the stamens were free and 
well formed, but others were coherent and associated, as in the three at 
fig. 24 
At fig. 26 is an appearance, more than once noticed among the 
appendages, of a delicate membrane with rudimentary stamens and 
pistils, which had been coiled up in a spiral manner. The stamens and 
pistils are bent back in the figure, but iw situ were erect and parallel 
to the axis of the coil. The membrane appears to be composed of 
rudimentary scales, cohering by their margins; or may we not rather 
say, that this membrane would have subdivided into such scales, if the 
developing process had proceeded to perfection? — At fig. 27 are forms 
exhibited by imperfectly organized stamens, and at fig. 28 by pistils, 
produced on the buds. 
Other modifications of the developing appendages to the bud are
