mira when compared to the taxa included in Chevaliera are related to the inflorescence structure and the texture of the bracts: the numerous and densely arranged branches are flabellate (vs.
Indeed, Bentham and Hooker (1880) placed the dasypogonoids (plus some other taxa now firmly placed in the lilioid order Asparagales) within the Poalean family Juncaceae, citing similarities in inflorescence structure.
The main problems in the interpretation of the inflorescence structure result from studies which did not consider the entire inflorescence (Vegetti, 2003); instead, attention was restricted to the position and arrangement of flowers in the final units of the often copiously branched inflorescence (Kukkonen, 1984).
One of the characters they analyzed was the partial inflorescence structure, for which they recognized only two states: there may be present only fertile flowers and modified sterile flowers.

1 and 2): (1) Gross Inflorescence Structure (unispicate, 0; occasionally unispicate, 1; multispicate, 2; highly compound, 3); (2) Degree of Utricle Fusion (closed, 0; open, 1); (3) Spikelet Sexuality (one-flowered pistillate, 0; bisexual, but monoecious, 1; perfect, 2); (4) Stigma Number (three, 0; two, 1); (5) Cladoprophylls (present, 0; absent, 1); (6) Inflorescence Prophylls (present, 0; absent, 1).
Evolution in the Myrtaceae--Evidence from inflorescence structure.
Observed heterochronic differences in the inflorescence structure may be divided into three types: spatial difference s in the relationship between the unit inflorescence and the subtending leaf (hysteranthy); differences in the time of formation and/or the duration of whole axes; and changes in development pathways, leading to shoot dimorphism.
Together, these fossils provide character information for inflorescence structure, flower morphology, fruit structure, and mature and juvenile wood anatomy.
Further floral and spikelet research in the Cariceae is needed in order to establish the nature of the male "flower" and to give more insight in the complex inflorescence structures.
