paraclade consists of a short hypopodium, a prophyll
, an epipodium and a
In the accessory branches, each of these accessory axes has its own prophyll
, in whose axils a prophyllar branch can be produced.
Each of these axillary shoots bears a prophyll
, a variable number of leaves, and ends in an inflorescence (axillary inflorescence).
A rhipidium is a (cymously) built partial inflorescence in which the prophyll
of a lateral axis subtends a new lateral axis, each axis ending in a flower.
2006) and easily separated from all other Cyperaceae by naked unisexual flowers where the female is surrounded by a sac-like prophyll
known as a utricle or perigynium (Fig.
For example, Bugnon and Joffrin, and Brunaud, saw the first foliar structure initiated on what we call a "stolon complex" as a prophyll
of the whole axillary complex: but in material studied by dissection it is perfectly clear that the first foliar structure is initiated on the stolon complex itself.
The general concordance of additional features such as root growth, vascular anatomy, sieve-tube plastids, prophyll
number, leaf architecture, microsporogenesis, pollen types, and patterns of floral morphology supports the general view that both monocots and dicots are natural lineages.
characteristically develop only in leaf axils, a palea that was homologous with a prophyll
would be absent in a truly terminal flower, and we suggest that the "lemma and flower" structures of Anomochloa represent terminal bracteate flowers rather than subterminal ones.
The wings, developed from two folded accrescent prophylls
, are membranous, with main veins radiating from the lower 1/3 of the central axis, 1-2 mm apart, forming reticulate festooned brochidodromous pattern, looping, with an intervening reticulum of looping finer veins.
Roy), the axillary bud of the prophylls
generates one flower; consequently, the florescence is formed by dichasia.
Vigneastra), a large subtropical species from Southeast Asia with branching inflorescences and inflorescence prophylls

d)Podostemoideae posses an additional envelope, homologous to prophylls
or leaves (spathella), whereas Tristichoideac have a cuplike cover (Cupule) (Rutishauser, 1997.
