Magnoliopsida - Magnoliales - Lauraceae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|H. Ecklund and J. Kvacek 1998||Inflorescences compound and elongate, consisting of a central axis bearing densely spaced and helically arranged lateral units. Central axis showing distinct and ovate scars following detachment of the lateral units. Lateral inflorescence units distinctly bilobed and supported by a small scale (bract?). Each lobe composed of several closely spaced and distichous, small, leaflike scales. Individual scales with a thick cuticle and a thin apical rim with perforations. Adaxial side of lateral units typically bearing seven (occasionally three, five or nine) sessile flowers in a proximal position and a variable number of small scalelike structures in a distal position. Flowers distinctly trimerous. Tepals six in two whorls; short and broadly triangular in the outer perianth whorl; longer and more narrowly triangular and with a distinct keel in the inner perianth whorl. Androecium consists of nine stamens arranged in three alternating whorls and three staminode-like structures in a fourth inner whorl. Filaments of the third whorl associated with paired staminal appendages. Anther dehiscence introrse in the two outer whorls of fertile stamens, extrorse in the inner whorl of fertile stamens. Anthers with distally expanded connective. Carpel solitary, erect, and ovoid. Globular resinous bodies densely distributed on the small, leaflike scales, tepals, and anthers. Trichomes short and frequently occuring on adaxial side of lateral units, more sparsely on carpels and filaments of stamens and staminodes.|
