This structure is terminal given that no rudimentary rachilla
Other finds include coconut shell (fragments in all deposits) and, less commonly, cotton/baobab seeds, sorghum and rice rachilla
The objectives of this present study were to establish the characteristics of the vascular system in the different parts of rachilla through which food was supplied to individual differentially growing grains of spikelet and correlate the same with their innate natures.
At each node, the rachilla bore a lemma in whose axil a floret axis ascended.

It is a mid-season, white pearl, six-rowed spring barley with smooth awns, short rachilla
hairs and more lateral vein barbs than Morex.
The most important variations include: a) flower sexuality: spikelets with male and female flowers may be gynandrous (with the female flower distal), androgynous (with the male flower distal) and mesogynous (with female flowers proximal and distal to the male flowers); b) shape (shortly ovate, elliptical, lanceolate, linear, ovate, etc); c) compression (laterally or dorsiventrally compressed or more or less terete); d) rachilla
internodes more or less straight, zigzag or flexuose; e) rachilla
prolongation exceeding (e.
The results imply that, grains along the rachis were less affected in their nutrient concentrations than those along the rachilla
The non-shedding trait occurs in rice by a toughening of the attachment of the spikelet base to the rachilla
, and as shown by Thompson (1996; 1997), this is accompanied by a subtle change in the cross section of the rachilla
attachment scar (also Sato 2002).
The spikelet in Eleocharis palustris consists of an indeterminate rachilla
Traditionally, genera have been distinguished on the basis of differences in the morphology of the utricle and rachilla
The first identifiable grass spikelets present after the divergence of these two genera have one fertile rioter with a lemma, a palea, no rachilla
extension (a rachilla
is a primary axis that joins the rioters and two glumes within a spikelet, and here it does not extend beyond the point of attachment of the fertile floret).
