Glossary and abbreviations

! – after the citation of type material: material seen.

a.s.l. – above sea level.

aciantheroid – pollen morphology, describes a surface that is marked by 1) irregularly protruding tetrads, 2) a tetraedic position of the sister pollen grains, and 3) borders of the sister grains recognisable by thin interruptions in the outer wall. The typical aciantheroid surface is seen in Fig. 43a+c: a domed tetrad with easily recognisable pollen grain walls.

bp – base pair(s).

BP – before present.

C – Centre, central.

CA – Central America.

E – east(ern).

FCP – Flora de Cuba Project.

GA – Greater Antilles.

ma – million years.

LA – Lesser Antilles.

lepanthoid – pollen morphology, describes a levelled surface with fused exinous layers of the outer tetrads. The sculpture may be psilate to punctate (Stenzel 2000).

Lundberg rooting – definition of a hypothetical outgroup with all characters (taxa) coded 0, i.e. absent.

octomerioid – pollen morphology, describes a psilate sculpture with a distal sporopollenin cap disintegrating into marginal ribbons, a reticulum, or gemmae (Stenzel 2000). This disintegration usually starts at the flanks of the exinous cap of a tetrad/pollen grain, however, in some cases it might affect the whole cap at once.

MP – maximum parsimony.

N – North(ern).

punctate – pollen morphology, the term as applied hereafter, does not automatically mean a tectal perforation (sensu Erdtman 1952) but refers to a small depression (< 1µm) on the surface of exposed pollen grains.

PFC – Proyecto Flora de Cuba. Herbarium material collected within this project received a special number, e.g. PFC 12345.

ramicaul – term coined by Stern & Pridgeon (1984) and adopted by Dod (1986b) for linguistic usage in Spanish. Refers to the non-pseudobulbous secondary stems in the subtribe Pleurothallidinae.
